    Multidisciplinary andrology deals with clinical application and modern technology for the evaluation and differential diagnosis of male infertility with emphasis on morphological, anatomical, biochemical, immunological, hereditary, and microbiological parameters. Little is known about the effects of diet, disease, stress, environmental, and drugs on male-related unexplained infertility of couples. Regional, national, and international centers of multidisciplinary andrology should provide (1) extensive and unique clinical services; (2) a computerized "patient referral center," (3) self-learning packages (slides/tape programs) for patients; and (4) a computer link to the National Library of Medicine and the Drug Information Center. Specialized laboratories and clinics can be served by expert consultants, visiting professors, bilingual and well-trained clinicians, nurses, laboratory technologists, computer operators, and related allied health personnel. Patient education pamphlets, updated every few years, can be distributed during training workshops when an extensive network of remote teleprinters can be utilized. Qualified client location may install a printer to allow on-site printing of reports in the shortest possible time. Special mailing containers are provided to clients who wish to mail their laboratory specimens. Other clinical services may include the following: 1. Central source of communication and information in andrology; 2. International roster of multidisciplinary andrology centers; 3. Patient referral to centers and consultations for developing countries; 4. Screening of husbands and wives for in vitro fertilization/embryo transfer (IVF/ET); 5. Screening of couples with unexplained infertility for sexually transmitted diseases (STDs) including AIDS; 6. Exchange of research material and methodology; 7. Coordination of multicenter research; 8. Organizing training workshops for clinicians, nurses, and laboratory technicians; 9. Establishing a repository

    Lumbar disc herniation is a common male disease. In the past, More academic attention was directed to its relationship with lumbago and leg pain than to its association with andrological diseases. Studies show that central lumber intervertebral disc herniation may cause cauda equina injury and result in premature ejaculation, erectile dysfunction, chronic pelvic pain syndrome, priapism, and emission. This article presents an overview on the correlation between central lumbar intervertebral disc herniation and andrological diseases, focusing on the aspects of etiology, pathology, and clinical progress, hoping to invite more attention from andrological and osteological clinicians.

    Two issues of this Journal are devoted to the history of andrology and male sexuality, from Hippocratic medicine to contemporary ethical problems due to the increasing role of technology in human reproduction. Studies have been devoted to: the Hippocratic Corpus, to authors of the Roman Empire, to Byzantine medicine; the transmission of ancient texts through Arabic and other languages of the Middle East; the influence of Constantinus Africanus' translations from Arabic to Latin; early modern theories about semen, male sexuality, impotence. Recent developments of biochemistry and epistemology are analyzed to show how these and other topics have influenced sexual ideas and behaviours until the discovery - around 1840 - of the chemical nature of male sexual hormones. In more recent years, technologies and cellular and molecular biology have opened new perspectives in the fields of fertilization and male sexuality, giving way at the same to new ethical, social and legal problems.

    Appropriate physical activity is one of the bases of healthy lifestyle. In fact, physical exercise and playing sport may be associated with both improvements and injury to both general and reproductive health. A biologically normal testosterone secretion appears fundamental in males to guarantee both a physiological exercise adaptation and safe sport participation. The reproductive system is highly sensitive to the effects of exercise-related stress and the reproductive hormones may both increase and decrease after different acute or chronic exercises. Exercise and sport participation may positively or negatively influence andrological health status depending on the type, intensity and duration of performed physical activity and on individual health status. In addition, prohibited substances administration (e.g. androgenic-anabolic steroids, and so forth) in competitive and non-competitive athletes represents the main cause of iatrogenic andrological diseases. Preventing and treating andrological problems in active healthy and unhealthy individuals is as important as promoting a correct lifestyle. Physicians need to be educated on the relationships between the male reproductive system and sport participation and on the great role of the pre-participation physical examination in the prevention of andrological diseases.

    Full Text Available Aiming to determine the relationship between the frequency of testicular shape and the andrological aspects in young Nellore bulls, 18,676 animals were assessed. All andrological examinations were performed between the years 2000 and 2008. Animals were classified as able for breeding, able for breeding in natural mating system, unable for breeding and discarded. The testicular shape was classified as long, fairly long, oval-long, spherical-oval, and spherical. The analysis of Pearson correlations was performed for testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major defects, minor defects and total defects. Testicles with oval shape prevailed (99.61%. It was obseved that 76.34; 66.34; 64.34; 58.33 and 50.00% of the animals were classified as sound for breeding for shapes long, fairly long, oval-long, spherical-oval, and spherical, respectively. Correlations between testicular shape with scrotal circumference, testicular volume, progressive motility, sperm vigor, major, minor and total defects were 0.26; 0.08; 0.00; 0.11; -0.02; 0.02 and -0.01, respectively. Testicular shape had no influence upon the andrological examination results. Testicles of long shape were prevalent within the population.

    Aim: To pursue whether cytogenetic aberrations correlate with specific spermatological or hormonal abnormalities.Methods: 305 infertile couples were investigated. All male partners were referred to a complete andrological workup with physical examination, determination of hormones, HIV testing and semen analysis. Cytogenetic analysis was carried out in both partners by means of standard techniques using cultured lymphocytes from peripheral blood. Results: Among the 305 couples, 10 men (3.2%) and 10 women (3.2%) showed constitutional chromosomal aberrations, including reciprocal translocations (n=7), Robertsonian translocations (n=3), inversions (n=3), other structural aberrations (n=4) and sex chromosome aberrations (n=3). In addition to the impaired sperm count in most of the patients, a tendency to an increased proportion of spermatozoa with acrosome defect was observed. Conclusion. Chromosomal aberrations may contribute to the low fertilization and pregnancy rates in the infertile couples.(Asian J Androl 2000 Dec;2:293-296)

    Aim: To improve workflow and usability by introduction of a new electronic patient record (EPR) and database.Methods: Establishment of an EPR based on open source technology (MySQL database and PHP scripting language)in a tertiary care andrology center at a university clinic. Workflow analysis, a benchmark comparing the two systems and a survey for usability and ergonomics were carried out, Results: Worlflow optimizations (electronic ordering of laboratory analysis, elimination of transcription steps and automated referral letters) and the decrease in time required for data entry per patient to 71% ± 27%, P<0.05, lead to a workload reduction. The benchmark showed a significant performance increase (highest with starting the respective system: 1.3 ± 0.2 s vs. 11.1 ± 0.2 s, mean ± SD). In the survey, users rated the new system at least two ranks higher over its predecessor (P<0.01) in all sub-areas.Conclusion: With further improvements, today's EPR can evolve to substitute paper records, saving time (and possibly costs), supporting user satisfaction and expanding the basis for scientific evaluation when more data is electronically available. Newly introduced systems should be versatile, adaptable for users, and workflow-oriented to yield the highest benefit. If ready-made software is purchased, customization should be implemented during rollout.

    Post-vasectomy semen analysis (PVSA) is the procedure used to establish whether sperm are present in the semen following a vasectomy. PVSA is presently carried out by a wide variety of individuals, ranging from doctors and nurses in general practitioner (GP) surgeries to specialist scientists in andrology laboratories, with highly variable results.Key recommendations are that: (1) PVSA should take place a minimum of 12 weeks after surgery and after a minimum of 20 ejaculations. (2) Laboratories should routinely examine samples within 4 h of production if assessing for the presence of sperm. If non-motile sperm are observed, further samples must be examined within 1 h of production. (3) Assessment of a single sample is acceptable to confirm vasectomy success if all recommendations and laboratory methodology are met and no sperm are observed. Clearance can then be given. (4) The level for special clearance should be methods contained within these guidelines. Surgeons are responsible both preoperatively and postoperatively for the counselling of patients and their partners regarding complications and the possibility of late recanalisation after clearance. These 2016 guidelines replace the 2002 British Andrology Society (BAS) laboratory guidelines and should be regarded as definitive for the UK in the provision of a quality PVSA service, accredited to ISO 15189:2012, as overseen by the United Kingdom Accreditation Service (UKAS).

    The traditional Chinese and andrology can be traced back to the ancient Chinese medical literature over 3000 years ago describing the diseases of male set,but it is only since mid 1980s of century whtn it was differentiated from traditional Chinese clinical medicine into an independent discipline that it has a great boom.The exact concept of this discipline was first presented and published in the literature in 1986.With concerted efforts of traditional Chinese andrologists,the discipline has been systematically established,enriched in content,properly categorized and progressively developed.However,judging from its present theoretical and clinical studies,the traditional Chinese andrology has not a uniform and definite positon in the entire system of traditional Chinese medicine and clinical disciplines,a due position in medical teaching and a far from uniform position in academic organizations.Seeing from the published literature and monographs,the discipline category of traditional Chinese andrology is also not uniform.All of this hinders the further development of the discipline.Therefore,in this paper the positioning and categorization of traditional Chinese andrology and their relationship with the development of the discipline are discussed.

    Full Text Available In addition to the annual report of the German IVF Registry (D·I·R the database of 498,784 ART cycles between 1998 and 2008 was analysed for aspects regarding andrology, medical and economical aspects of ICSI and stimulation with gonadotropins. The indication for an ICSI procedure is related to the retrieval of sperm. Seven percent of all ART cycles in the DIR are already performed with epididymal or testicular sperm due to azoospermia. The analysis of cycles with testicular sperm revealed that fertilisation and pregnancy rates are reduced in comparison to ejaculated or frozen sperm, but miscarriage and birth rates do not increase. The data recording of lifestyle parameters can be valuable in the future. The analysis of the D·I·R data demonstrates that restrictions on the reimbursement for ART cycles have significant impact on the use of IVF and ICSI treatments. Medical indications rather than economic reasons seem to be responsible for the increase in ICSI treatment. Since the commercial launch of GnRH antagonists in 1999 and 2000 more than 90 % of IVF and ICSI protocols in Germany are now performed with GnRH agonists (54.8 % and GnRH antagonists (31.5 %. Approximately 90% of the IVF and ICSI cycles in Germany are performed with recombinant FSH (rFSH, highly purified menotropin (HP-hMG or a combination of both. Non-medical factors can influence the choice of gonadotropins for stimulation. Women beyond the age of 34 probably have better IVF or ICSI outcome when the stimulation is performed with rFSH. J

Sin embargo, la mayoría de estas características dependen de eventos reproductivos de las hembras y, con excepción del perímetro escrotal, pocos estudios abordan las características andrológicas. Las estimaciones de las heredabilidades y correlaciones genéticas de las características testiculares y seminales, además del comportamiento sexual, podrán proveer alternativas para la elaboración de estrategias más adecuadas de selección para fertilidad, en conjunto con las demás características de interés económico.The sexual precocity and fertility of bovines have great impact on the economic success of commercial cattle herds, where some reproductive traits have been adopted as selection criteria. However, the majority of these traits depend on reproductive events of the females and, with exception of the scrotal circumference, few studies approach others andrological traits. The estimation of heritabilities and genetic correlations of testicular and seminal traits and also sexual behaviour, will allow to provide alternatives for the design of more appropriate selection strategies for fertility, together with other economic traits.

The introduction of biochemical tests into the analysis of male factor has the advantage that standardized assays with a coefficient of variafion characteristic of clinical chemistry are performed, in contrast to biological test systems with a large variability .Biochemical parameters may be used in clinical practice to evaluate the sperm fertitizing capacity (acrosin, aniline blue,ROS), to characterize male accessory sex gland secretinns (fructose, a-glucosidase, PSA), and to identify men with silent genital tract inflammation (elastase, C'3 complement component, coeruloplasmin, IgA, IgG, ROS).

    Population aging is continuously increasing in Italy and in the World. Individuals aged 60 years or more are currently 10,500,000 and will be 13,000,000 in 2015. Life quality in geriatric ages includes the maintenance of sexual power: according to recent data (Carrol et al., 1992), 80% of impotence cases are due to organic causes. In addition, the use of drugs can cause impotence. Among them tiazidic diuretics may cause an increase of sexual disturbances. Other drugs with this potential are digitalis, antihypertensive drugs (particularly beta blockers), major and minor tranquillizers, antidepressant, H2 receptor antagonists, antiparkinsonian cholinergic drugs and estrogens employed in the treatment of prostate tumors. Diseases of geriatric age that can alter sexual power are diabetes mellitus, ischemic heart disease for the accompanying depression and for the use of antidepressants; severe hypertension is complicated by impotence in 15% of cases. Among neurological diseases Parkinson's disease and multiple sclerosis can be causes of sexual dysfunctions. Patients on hemodialysis can be impotent, with recent data (Soloh et al 1992) showing that erythropoietin treatment of anemia also improve sexual dysfunctions. Prevention from a geriatric standpoint should be base on action on known risk factor as smoking, alcohol abuse and dislipidemias and with the activation of a close drug vigilance.

    Stem cells hold great promise for regenerative medicine because of their ability to self-renew and to differentiate into various cell types. Although embryonic stem cells (BSC) have greater differentiation potential than adult stem cells, the former is lagging in reaching clinical applications because of ethical concerns and governmental restrictions.Bone marrow stem cells (BMSC) are the best-studied adult stem cells (ASC) and have the potential to treat a wide variety of diseases, including erectile dysfunction (ED) and male infertility. More recently discovered adipose tissue-derived stem cells (ADSC) are virtually identical to bone marrow stem cells in differentiation and therapeutic potential,but are easier and safer to obtain, can be harvested in larger quantities, and have the associated benefit of reducing obesity. Therefore, ADSC appear to be a better choice for future clinical applications. We have previously shown that ESC could restore the erectile function of neurogenic ED in rats, and we now have evidence that ADSC could do so as well. We are also investigating whether ADSC can differentiate into Leydig, Sertoli and male germ cells. The eventual goal is to use ADSC to treat male infertility and testosterone deficiency.

  11. The role of prolactin in andrology: what is new?

    2015-09-01

    Prolactin (PRL) has been long deemed as a hormone involved only in female reproduction. However, PRL is a surprising hormone and, since its identification in the 1970s, its attributed functions have greatly increased. However, its specific role in male health is still widely unknown. Recently, low PRL has been associated with reduced ejaculate and seminal vesicle volume in infertile subjects. In addition, in men consulting for sexual dysfunction, hypoprolactinemia has been associated with erectile dysfunction and premature ejaculation, findings further confirmed in the general European population and infertile men. Several metabolic derangements, recapitulating metabolic syndrome, have also been associated with low PRL both in men with sexual dysfunction and from the general European population. In men with sexual dysfunction, followed-up for more than 4 years, low PRL was identified as an independent predictor of the incidence of major adverse cardiovascular events. Finally, an association with anxiety or depressive symptoms has been found in men with sexual dysfunction and from the general European population. While a direct role for impaired PRL function in the pathogenesis of these reproductive, sexual, metabolic and psychological disorders is conceivable, the possibility that low PRL is a mirror of an increased dopaminergic or a decreased serotonergic tone cannot be ruled-out. Hyperactivity of the dopaminergic system can explain only a few of the aforementioned findings, whereas a hypo-serotonergic tone fits well with the clinical features associated with low PRL, and there is significant evidence supporting the hypothesis that PRL could be a mirror of serotonin in the brain.

    Introduction: Erectile dysfunction (ED) is a common occurrence and its incidence is expected to increase significantly along with the increase in various lifestyle diseases. The drug utilization for ED is very low. Also, studies describing the prescription pattern in ED are lacking. Materials and Methods: We conducted a retrospective cross-sectional observational study, including a drug utilization analysis, of 606 prescriptions as per the standard guidelines (WHO and STROBE). Results: Out of 606, 249 (41%) were from the age group of 30-39 years. Addictions were present in 388 (64%). Out of 606, 186 had urological, 154 had cardiovascular and 102 had psychological co-morbid disorders. Out of 348, 201 were prescribed Tadalafil (low dose) on a once daily basis. Out of 172, 121 were prescribed Sildenafil (high dose) on an ‘as and when required’ basis. Nutritional/ herbal supplements were prescribed in 126/606. The ratio of ‘Prescribed Daily Dose’ to ‘Defined Daily Dose’ of Tadalafil, Sildenafil, and Dapoxetine were 1.1, 1.3 and 1.5 respectively. Conclusion: Measures for de-addiction play an important role in the overall management of ED. The most common co-morbid disorders were urological, like BPH, LUTS, etc, followed by cardiovascular, psychological and diabetes. Overall, rational pharmacotherapy was observed. Tadalafil was the most commonly prescribed drug for ED. The main factor in the selection of a particular PDE5 inhibitor was its pharmacokinetics and cost. Udenafil, being the costliest, was the least prescribed. Dapoxetine was used in a significant number of individuals primarily for PE with ED. The combination of Papaverine, Chlorpromazine ± Alprostadil was used as intracavernosal injection in patients not responding to oral drugs. PMID:26393163

    Since release of the latest WHO manual with the new lower reference values of semen parameters, a lot of discussion has been raised about their usefulness and appropriateness for assessment of male fertility. As with the previous reference values the new limits do neither allow an andrological diagnosis based on nosological criteria nor clear-cut differentiation between fertility and sub-/infertility.Therefore, considering the fact that fertility is a continuum, the new lower reference limits should not be overestimated. Most probably,more sperm function tests, such as determination of DNA integrity, and-in the future-assessment of biomarkers, such as sperm proteomics will be included into andrological work-up, thus resulting in a more personalized approach of infertility management. On the other hand, the detailed instructions for standard and advanced semen analysis provided in the new manual are very much appreciated and should be adopted by each seriously working laboratory.

To date, PET/CT with F.D.G. has never been used for functional study of testes with andrology aim. The objective is to search an eventual correlation between the F.D.G. testes uptake and spermatology examination. Conclusions: This preliminary study shows that among men without any known testes pathology, there is a significant correlation between the F.D.G. testes uptake and the principal parameters of masculine fertility. If these results are confirmed, clinical applications could appear in the diagnosis and prognosis exploration of hypo fertility. (N.C.)

    Full Text Available Unexplained male infertility is a diagnosis reserved for men in whom routine semen analyses results are within normal values and physical as well as endocrine abnormalities were ruled out. In addition to erectile problems and coital factors, immunologic causes and sperm dysfunction may contribute to such condition. New etiologies of unexplained male infertility include low level leukocytospermia and mitochondrial DNA polymerase gene polymorphism. Contemporary andrology may reveal cellular and sub-cellular sperm dysfunctions which may explain subfertility in such cases, thus aiding the clinician to direct the further work-up, diagnosis and counseling of the infertile male. The objective of this article is to highlight the concept of unexplained male infertility and focuses on the diagnosis and treatment of this condition in the era of modern andrology and assisted reproductive techniques. Extensive literature review was performed using the search engines: Pubmed, Science-direct, Ovid and Scopus.

  18. Functional testicular evaluation using PET/CT with 18F-fluorodeoxyglucose

    International Nuclear Information System (INIS)

    PET/CT using 18F-FDG is a well-established diagnostic examination in oncology, cardiology and neurology. The clinical significance of nontumoral testicular uptake of FDG is unknown. Functional testicular imaging may have important clinical applications in the diagnosis and prognosis of male infertility. The aim of this study was to determine the andrological value of a FDG PET/CT in analysing testicular function, by correlating the PET/CT data with the sperm parameters. Retrospective analysis of FDG PET/CT in 20 consecutive cancer patients without testicular pathology in whom two semen samples had been obtained for analysis before any chemotherapy. FDG PET/CT parameters were the mean standardized uptake value (SUVmean), used for measuring the intensity of uptake, and the functional testicular volume (FV). For statistical analysis, a Spearman's rank correlation test and a Mann-Whitney test were used. Of 20 patients (mean age 22 years), 18 had provided two sperm samples for cryopreservation. Sperm concentration was above 20 x 106/ml in 55% of the patients. The intensity of uptake and the FV were correlated with the total sperm count, the sperm concentration and motility (p < 0.05). The difference in SUVmean between the two testes showed an inverse correlation with sperm concentration (p = 0.036). Normospermic and oligospermic men had significant differences in: (1) mean SUVmean, (2) mean FV, and (3) the difference in intensity of uptake between the testes (p < 0.05). This is the first report on the andrological value of FDG PET/CT in analysing nontumoral testicular function. This pilot study showed a significant correlation between intensity of uptake of FDG and testicular FV with the main sperm parameters. PET/CT with FDG could become a useful new tool in assisted reproductive technologies and other andrological or urological applications. (orig.)

    Full Text Available Objective: To assess the proportion of patients with Peyronie’s Disease (PD and the possible association with its potential risk factors in the general population of the central and western Sicily in our weekly andrological outpatient clinic. Materials and methods: We recruited a sample of 279 consecutive patients consulting our andrological outpatient clinic. Two arms were created: the first one composed by PD patients (men with symptoms suggestive for PD, the second one composed by patients with other andrological diseases (control arm. For each patient we evaluated the age, cigarette smoking, diabetes, blood hypertension and erectile function. In the PD arm we administered validated questionnaires to determine the erectile function status by the International Index of Erectile Function 5 (IIEF-5 and the pain status during erection by the Visual Analogue Scale (VAS. A univariate analysis was conducted using R software. Results: We enrolled 279 consecutive patients. The number of PD patients was 97 (34,7%. The univariate analysis showed a correlation between PD and cigarette smoking (p = 0.0242, blood hypertension (p < 0.001, erectile dysfunction (p < 0.001. No significant association was observed between diabetes and PD (p = 0.358. The median age of PD arm was 60 years and the median age of the control arm was 63,5 years; therefore the median age of PD arm resulted lower than the median age of the control arm (p = 0,031. Conclusions: Peyronie’s disease is more common than we might think; furthermore it can be diagnosed among young patients. According to our results, cigarette smoking and blood hypertension may be considered statically significant risk factors for developing PD. On the contrary diabetes seems not to be a risk factor for PD. According to our results PD should be sought also in young patients. Further studies are necessary to confirm that removing the indicated risk factors may reduce the incidence of PD.

Based on the current epidemiological and experimental data, most common etiological factors of gynecomastia were investigated. A multiple-valued role of various causes of gynecomastia in several age-groups was revealed. Literature data show that gynecomastia may be a manifestation of various diseases: endocrine, genetic, systematic. As well as that, gynecomastia may occur in patients with oncological diseases. However, gynecomastia can be an iatrogenic complication. Currently, we continue to make insights to the problem of gynecomastia in order to be able to classify its etiological factors and determine its basic pathogenesis pathways.

    2016-05-01

    This study aimed to report penile dimensions in adult Egyptian males consulting for small-sized penis (SSP) and describe their demographics and andrological profile. A case control study was designed through retrospective data analysis of patients (n = 239) seeking advice for SSP and a control group (n = 59). This included sociodemographics, other andrological complaints, and penile dimensions (pendulous length [PL], penopubic or total length [TL], and circumference [CF]) at flaccid and erect states and the size of the prepubic fatty pad. The results reported that most patients were single, students, and smokers and had not completed a university education. Several patients reported falsely premature ejaculation (PE), penile curvature (PC), and small-sized testes. Most penile dimensions of the patients (mean, cm) were significantly lower than those of the controls, whether in flaccid (PL: 7.4 vs. 8.05, p = .008; CF: 8.7 vs. 8.98, p = .026) or erect state (PL: 11.8 vs. 13, p = .000; TL: 14.2 vs. 15, p = .000; CF: 11.3 vs. 11.8, p = .003). However, no patient presented with a pendulous penile length <4 cm in flaccid or <7 cm in erect state. In conclusion, Egyptian men consulting for SSP did not have true small organs, but their penile dimensions were slightly smaller than those of men without such complaint.

    Surgery in germ cell tumors of the testis (TGT) may result in andrological disorders, both after orchiectomy and after retroperitoneal lymphadenectomy (RPLND). Bilateral orchiectomy suppresses both testicular functions: exocrine and endocrine. In selected cases with bilateral TGT (metachronous/synchronous), or in the case of TGT in monorchid patients, partial orchiectomy (enucleation of the tumor) can preserve both functions with a low risk of relapse in residual testicular parenchyma, in the absence of intraepithelial neoplasia (TIN). In cases of TIN and normal testosterone levels (80%), the fertility is maintained in 50% of patients. In these cases the use of radiotherapy on the residual testicular parenchyma can prevent the future development of invasive cancer, though compromising the hormonal function. The RPLND (open or laparoscopic) can produce major side effects, such as retrograde ejaculation. Knowledge of the adrenergic fiber retroperitoneal neuroanatomy enables to implement a "nerve sparing" surgery with an almost total reduction of this serious side effect, but that option is only available in few centers of excellence. Semen cryopreservation has become a common practice performed before any treatment that might impact on the andrological function of patients. PMID:23371266

    This study aimed to report penile dimensions in adult Egyptian males consulting for small-sized penis (SSP) and describe their demographics and andrological profile. A case control study was designed through retrospective data analysis of patients (n = 239) seeking advice for SSP and a control group (n = 59). This included sociodemographics, other andrological complaints, and penile dimensions (pendulous length [PL], penopubic or total length [TL], and circumference [CF]) at flaccid and erect states and the size of the prepubic fatty pad. The results reported that most patients were single, students, and smokers and had not completed a university education. Several patients reported falsely premature ejaculation (PE), penile curvature (PC), and small-sized testes. Most penile dimensions of the patients (mean, cm) were significantly lower than those of the controls, whether in flaccid (PL: 7.4 vs. 8.05, p = .008; CF: 8.7 vs. 8.98, p = .026) or erect state (PL: 11.8 vs. 13, p = .000; TL: 14.2 vs. 15, p = .000; CF: 11.3 vs. 11.8, p = .003). However, no patient presented with a pendulous penile length <4 cm in flaccid or <7 cm in erect state. In conclusion, Egyptian men consulting for SSP did not have true small organs, but their penile dimensions were slightly smaller than those of men without such complaint. The proper sexual education program is highly advisable in these situations to avoid the myths and misconceptions about sexuality. PMID:25563384

It can be distressing because of its negative effect on self-esteem, quality of life, and interpersonal relationships. Oral phosphodiesterase-5 inhibitors (PDE5 inhibitors are now the first choice of treatment in ED. The availability of three (sildenafil citrate, tadalafil, and vardenafil well tolerated and effective oral PDE5 inhibitors gives treatment options for men with ED. Although the mechanism of action is the same for the three drugs, they differ in their pharmacokinetics. Several preference studies were conducted between the three PDE5 inhibitors but they were not free from bias. Because of the lack of overwhelming reliable data showing that one PDE5 inhibitor is superior to another, current opinion is that the individual patient should have the opportunity to test all three drugs and then select the one that best suits him and his partner.Keywords: erectile dysfunction, PDE5 inhibitors, patient preference

    Chronic orchialgia (CO) is a common complaint in urology or andrology. Due to its complicated pathogenesis, the diagnosis and treatment of CO are quite challenging. Based on different etiologies, CO can be idiopathic or secondary. Idiopathic CO accounts for approximately 50% of the cases and is probably associated with Wallerian degeneration in the spermatic cord nerves and peripheral sensitization. Secondary CO can be attributed to direct causes and its treatment focuses on the pathologic condition identified. The main methods for the treatment of CO include conservative and surgical strategies, among which microsurgical spermatic cord denervation ( MSCD) is an effective and minimally invasive option, while orchiectomy is but the last alternative when no other means is left.

    Good-quality semen is a prerequisite for successful and profitable artificial insemination (AI) of modern dairy cattle. Fertility of the bulls is evaluated with andrological examinations and semen analyses, such as morphology. However, little attention has been paid to the inheritance of bull fertility. In this study, we correlated sperm morphology, birth year and station of 695 AI bulls with calving rate (CR). Sperm morphology was clearly associated with CR underlining the usefulness of morphological examination in the assessment of fertility. The correlation between the proportion of normal spermatozoa and CR was significant (p sires to study the inheritance of fertility. Sire's CR did not correlate with the CR of the sons (p = 0.218).

    Pain at ejaculation/orgasm perceived in perineum, urethra and/or urethral meatus, has a profound impact on the quality of life of the affected man. Although underestimated, this condition is reported to have a 1-9.7% prevalence over the general population. METHODS. Structured review of the relevant available literature. RESULTS. Among the main causes of pain experienced at ejaculation/orgasm are: prostatevesicular causes (LUTS/BPH, prostatitis, ejaculatory duct obstruction, vesicular stone), postsurgical causes (radical prostatectomy, inguinal hernioplasty), pharmacologic causes (antidepressants), psychogenic causes (psychosexual conflicts, sexual abuse), rare causes. For these pathologies, diagnostic and therapeutic strategies have been proposed. CONCLUSIONS. Ejaculatory pain is associated with a high level of personal distress, and represents a possible request for help within the andrologic/urologic area. Each field specialist should be competent in correctly interpreting every single case, in order to manage it appropriately. PMID:21086282

    In some cases, human spermatozoa to be used for in vitro fertilization are processed from testicular or epididymal biopsies collected in the clinic or operating room. An appropriately equipped Andrology or Embryology Laboratory is required. Sterility must be maintained at all stages from collection and transport to identification and processing to insemination or cryopreservation. The technologist must be able to properly process and identify spermatozoa from aspirates, seminiferous tubules or pieces of testicular tissue. Recovery of undamaged spermatozoa from tubules or tissue requires mincing, squeezing, or vortexing the tissue, usually without the need of enzymatic digestion. A motility stimulant such as Pentoxifylline is commonly used to calculate the number of functionally competent spermatozoa. After recovery, spermatozoa may be used immediately for IVF-ICSI, incubated overnight prior to IVF-ICSI, or cryopreserved for future use. Methods for identifying, purifying, and determining the number and motility of spermatozoa during these processes are presented. PMID:22992917

In this manuscript, we provide a brief review of the history of AAS and discuss clinical applications of two of the more well-known AAS: nandrolone and oxandrolone. Both agents exhibit favorable myotrophic/androgenic ratios and have been investigated for effectiveness in numerous disease states. We also provide a brief synopsis of selective androgen receptor modulators (SARMs) and postulate how these orally active, non-aromatizing, tissue-selective agents might be used in contemporary andrology. Currently, the applications of testosterone alternatives in hypogonadism are limited. However, it is tempting to speculate that these agents may one day become accepted as alternatives, or adjuncts, to the treatment of male hypogonadism.

    Full Text Available Selection of sperm is a crucial part in assisted reproductive treament (ART. Sperm preparation methods do mainly differentiate according to sperm motility and are indispensable for therapies like intrauterine insemination, in-vitro fertilization (IVF and intracytoplasmic sperm injection (ICSI. Although in the beginning of the era of ICSI andrology was thought to play a minor role, ICSI has offered new options by correlating the treatment outcome to parameters of the individual applied spermatozoon. Hence the possibility for selecting spermatozoa has shifted from parameters which characterize the entire sperm cohort to a single-sperm specific assessment technology. Consequently, sperm selection is a topic which is intensively discussed nowadays. This article gives a comprehensive overview of the technologies which can be applied today and give a prospective on future techniques.

    Full Text Available Introduction: Few studies on the prevalence of male sexual diseases are currently available due to difficult application of observational studies or andrological disease prevention campaigns on large series of apparently healthy subjects. The medical check-up linked to compulsory military service represented in Italy a valid tool for epidemiological and observational study for 18 year old boys from 1861 to 2004. The stopping of compulsory military service and its related medical check-up could have determined an important social impact in terms of a lower level of attention and care on male genital/sexual diseases. The aim of the present observational study was to check the prevalence of genital/ sexual diseases among young male high-school students and promote an alternative campaign of information among young students. Methods: A prospective observational analytical study on young male students was conducted by 6 urological centres. Genital and sexually transmitted diseases were presented with slides to students in a general assembly. Some students were then counselled and filled out a short questionnaire on their lifestyle. Results: 12,535 students (10,432 males-83.6% followed the presentation. and 4,897 males (46.7% decided to be checked-up by the urologist and out of them 1554 (31.7% presented relevant andrological diseases. Five-hundred students completed the questionnaire concerning their lifestyle. Many of them had not yet experienced condom use during sexual intercourse (27.8%. Drug abuse was reported by 39.6% of subjects and alcohol consumption in 80.8% of them. Conclusions: These data suggest the need for a national information campaign on male sexual disorders to promote sexual health.

    Background Pharmacological therapy has been considered as the first-line treatment for patients with uncomplicated benign prostatic hyperplasia (BPH). The aim of this study was to evaluate the efficacy and safety of tamsulosin compared with a placebo for treating BPH. Methods The randomized placebo-controlled trials (RCT) of tamsulosin for the treatment of BPH from all over the world were searched. PubMed, Ovid, ScienceDirect, EBSCO, CBM, and CNKI were searched, as well as a manual search of four Chinese journals: Chinese Journal of Andrology, National Journal of Andrology, Chinese Journal of Urology, and Journal of Clinical Urology was also performed. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted the data from the eligible studies, with confirmation by cross-checking. Divergences of opinions were settled by discussion. Meta-analysis was processed by Rev Man 5.0 software, fail-safe number was performed by SAS8.0 software. Results Seven RCTs involving 2455 men met the inclusion criteria. The basic characteristics of patients were comparable in all the studies. Comparing three common criteria: international prostate symptom score (IPSS)/Boyarsky symptom score, maximum flow rate (MFR), quality of life (QOL), tamsulosin was better than placebo at improving IPSS and MFR, with no significant difference in the QOL. Adverse events of tamsulosin also showed no significant difference from the placebo group (Z=1.62, P=0.10, OR=1.22, 95% CI 0.96-1.54).Conclusions Tamsulosin is better than placebo at improving IPSS and MFR. Adverse events of tamsuloisn show no significant difference compared with placebo. More high quality trials with larger samples and longer follow-up are proposed.

    Full Text Available Abstract The onset of clinical assisted reproduction, a quarter of a century ago, required the isolation of motile spermatozoa. As the indication of assisted reproduction shifted from mere gynaecological indications to andrological indications during the years, this urged andrological research to understand the physiology of male germ cell better and develop more sophisticated techniques to separate functional spermatozoa from those that are immotile, have poor morphology or are not capable to fertilize oocytes. Initially, starting from simple washing of spermatozoa, separation techniques, based on different principles like migration, filtration or density gradient centrifugation evolved. The most simple and cheapest is the conventional swim-up procedure. A more sophisticated and most gentle migration method is migration-sedimentation. However, its yield is relatively small and the technique is therefore normally only limited to ejaculates with a high number of motile spermatozoa. Recently, however, the method was also successfully used to isolate spermatozoa for intracytoplasmic sperm injection (ICSI. Sperm separation methods that yield a higher number of motile spermatozoa are glass wool filtration or density gradient centrifugation with different media. Since Percoll® as a density medium was removed from the market in 1996 for clinical use in the human because of its risk of contamination with endotoxins, other media like IxaPrep®, Nycodenz, SilSelect®, PureSperm® or Isolate® were developed in order to replace Percoll®. Today, an array of different methods is available and the selection depends on the quality of the ejaculates, which also includes production of reactive oxygen species (ROS by spermatozoa and leukocytes. Ejaculates with ROS production should not be separated by means of conventional swim-up, as this can severely damage the spermatozoa. In order to protect the male germ cells from the influence of ROS and to stimulate

The samples were sperm specimens of eighteen infertile couple male or volunteers who were infertile with age ranged between 20-40 years old. The samples   were divided into two groups: treatment group (caffeine + EBSS and control group (EBSS. The data were analysed statistically by normality test (Kolmogorov - Smirnov Goodness of Fit Test, Homogeneity test, and Paired Student’s t test.  Results: The results showed that the caffeine addition in EBSS medium could increase significantly (p<0.05.  The integrity of the sperm membrane obtained were from 81.30 % to 86.60 % and acrosomal reaction from 82.60% to 89.60% evaluated by hypo-osmotic swelling test (HOS. The conclusion of this study is that addition of caffeine in EBSS medium increases significantly membrane integrity and acrosomal reaction of the human sperm.

    For many years, andrologists have sought ways of assessing sperm fertility, especially of new sires entering the breeding chain. As knowledge of the complex processes that enable sperm to fertilize eggs has increased, it has become clearer that quantitative estimation of the fertilizing potential of a sire or an ejaculate is actually unlikely ever to be fully realized. Here, we propose that a better approach is to identify substandard males and semen samples. During the past decades, the use of fluorescence technologies in biomedical science has burgeoned, with the development of very powerful instrumentation such as confocal microscopy and flow cytometers of ever-increasing capabilities together with a vast range of fluorochromes and fluorochrome conjugates. This technology has been applied to andrology but thus far in only a relatively simple way. In this review, we offer strategies for assessing a large range of sperm functions thought to be related to fertilizing ability over a temporal window rather than at a single time point. From such an assessment profile, sperm samples that over-respond or do not respond sufficiently could be identified, termed dysfunctional and rejected. We outline the rationales behind such tests, present information on new potentially useful fluorochromes and current flow cytometer models that would be suitable for the multicolour multifunctional tests we propose, and we offer suggestions as to how andrologists might design such multicolour tests for themselves.

    The purpose of the study was to investigate the possible effect of an environmental organochlorine, dichlorodiphenyldichloroethylene (p,p'-DDE), on male fertility assessed by main sperm variables, conducted through a case-control study on young men attending the andrology laboratory in the context of infertility investigation in the couple. Blood and semen samples were obtained from 73 young men considered as fertile based on semen analysis (controls) and 82 classified as subfertile or unfertile (cases). Standard clinical analysis of semen was performed and identification and quantification of p,p'-DDE in serum and in seminal plasma were done by gas chromatography. No p,p'-DDE was detected in the seminal plasma of either group. Blood concentration of p,p'-DDE in both groups was very low and did not differ between cases and controls; however, blood samples were obtained from 23 mothers in the control group, and from 19 in the case group, and p,p'-DDE serum level was significantly higher in the mothers of subfertile men. These data suggest that male infertility could be associated with exposure of the mothers to p,p'-DDE with deleterious effects restricted to intra-uterine life and thus undetected in blood or seminal plasma of subfertile men.

    Flow cytometry is now a recognized methodology within animal spermatology, and has moved from being a research tool to become routine in the assessment of animal semen destined to breeding. The availability of 'bench-top' flow cytometers and of newer and versatile markers for cell structure and function had allowed the instrumentation to measure more sperm parameters, from viability to reactiveness when exposed to exogenous stimuli, and to increase our capabilities to sort spermatozoa for potential fertilizing capacity, or chromosomal sex. The present review summarizes the state of the art regarding flow cytometry applied to animal andrology, albeit keeping an open comparative intent. It critically evaluates the present and future capabilities of flow cytometry for the diagnostics of potential fertility and for the development of current reproductive technologies such as sperm freezing, sperm selection and sperm sorting. The flow cytometry methods will probably further revolutionize our understanding of the sperm physiology and their functionality, and will undoubtedly extend its application in isolating many uncharacterized features of spermatozoa. However, continuous follow-up of the methods is a necessity owing to technical developments and the complexity of mapping spermatozoa.

    Full Text Available A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA area pre- and post-Hurricane Katrina. We retrospectively evaluated semen analyses data (n = 3452 of 1855 patients who attended the Tulane University Andrology/Fertility Clinic between 1999 and 2013. The study inclusion criteria were men whose semen analyses showed ≥ 1.5 ml volume; ≥15 million ml -1 sperm concentration; ≥39 million total sperm count; ≥40% motility; >30% morphology, with an abstinence interval of 2-7 days. After the inclusion criteria applied to the population, 367 normospermic patients were included in the study. Descriptive statistics and group-based analyses were performed to interpret the differences between the pre-Katrina (Group 1, 1999-2005 and the post-Katrina (Group 2, 2006-2013 populations. There were significant differences in motility, morphology, number of white blood cell, immature germ cell count, pH and presence of sperm agglutination, but surprisingly there were no significant differences in sperm count between the two populations. This long-term comparative analysis further documents that a major natural disaster with its accompanied environmental issues can influence certain semen parameters (e.g., motility and morphology and, by extension, fertility potential of the population of such areas.

    Full Text Available The performances of the diluents TES and CEBRAN II were compared as cryopreservatives of semen from non human primates of the genus Ateles. The experiment was carried out using one Ateles marginatus and two Ateles paniscus specimens, males and adults, maintained in the same captivity conditions at the National Center of Primates (CENP-SVS/MS. The animals were subjected to clinical and andrological examinations - testicular biometry - before the semen collection by eletroejaculation. Evaluations of motility and forward movement in the fresh semen were made. Semen were made dilution was made with the diluents TES and CEBRAN II. The ejaculates were diluted with the diluents (2:1proportion, packed in 0.25mL plastic straws and cryopreserved in liquid nitrogen. After thawing, the packed ejaculates were appraised in thermo resistance test (TTR. The averages of volume and concentration were, respectively, 1.94mL (0.83 and 3,020,000 sptz/mL (275.97. The pH 8 and seminal coagulation were observed in all samples. The results suggest that the TES diluent presents better efficiency in the preservation of Ateles semen than CEBRAN II.

    Spinal cord injury (SCI) in men results in defects in erectile function, ejaculatory process and male reproductive potential. There are alterations in the capacity of men with SCI to achieve reflexogenic, psychogenic and nocturnal erections. The sexual function in different stages after SCI and the types of erections depend mainly on the completeness of the injury and the level of neurological damage. Furthermore, most of the SCI men demonstrate defects concerning the entrance of semen into the posterior urethra and the expulsion of the semen through the penile urethra and the urethral orifice. In addition, SCI men develop defects in the secretory function of the Leydig cells, Sertoli cells and the male accessory genital glands. The overall result is a decreased quality of the semen is recovered either with penile vibratory stimulation (PVS) or with electroejaculation. Nowadays the therapeutic andrological approach of SCI men focuses on achievement of erectile function, recovery of spermatozoa and assisted reproductive technology. The first line of therapy recommended for infertility in SCI men is collection of semen via PVS with concomitant evaluation of total motile sperm yields for assisted conception which may include intravaginal insemination, intrauterine insemination, or in vitro fertilisation/intracytoplasmic sperm injection. Patients failing PVS may be referred for electroejaculation or surgical sperm retrieval. PMID:20500744

    The pelvic congestion syndrome has been widely studied in the female sex, while there are not many publications on the male equivalent. Prostatitis represent the most frequent affections of the genito-urinary male tract that require the urologic consult, but in the majority of the cases the etiology of such affections remains unknown. Some forms of microscopic hematuria or macroscopic hematuria are also cryptogenetic. Varicocelectomy is widely given in the infertile patients, but not always the intervention achieves a recovery of the semen quality. In this work we revisit the anatomy of the pelvic male venous drain and we depict its objective findings with the echo-color-Doppler sonography (ECD). The purpose of the study is to encourage a polycentric uro-andrologic search on large numbers, with the goal of resolve if the ECD pictures of congestion pelvic syndrome could have relation with some "prostatitis syndromes", with some cryptogenetic hematuria and/or with the prognosis of the infertile patients undergone to varicocelectomy.

    Full Text Available ABSTRACT This study describes a new method of microcentrifugation as an improved, viable, cost-effective option to the classical Cytospin apparatus to confirm azoospermia. Azoospermic semen samples were evaluated for cryptozoospermia by a centrifugation method similar to that of World Health Organization guidelines (2010; entire specimen centrifuged at 3000g for 15 min, and aliquots of the pellet examined. Then, if no sperm were detected, the pellet from that procedure was resuspended in culture medium, centrifuged (2000g for 15 min, and the entire pellet spread on a 4 X 6mm area of a slide and stained using the Christmas tree method (Nuclear-Fast solution and picric acid. The entire stained area was examined for the presence or absence of sperm. A total of 148 azoospermic samples (after standard WHO diagnosis were included in the study and 21 samples (14.2% were identified as sperm-positive. In all microcentrifugation slides, intact spermatozoa could be easily visualized against a clear background, with no cellular debris. This novel microcentrifugation technique is clearly a simple and effective method, with lower cost, increasing both sensitivity and specificity in confirming the absence or presence of spermatozoa in the ejaculate. It may represent a step forward of prognostic value to be introduced by andrology laboratories in the routine evaluation of patients with azoospermia in the initial semen analysis.

    The objective of this study was to investigate the relations of basic semen parameters and reproductive hormones with different surrogate measures of adiposity: body mass index (BMI), body fat percentage (BF%), waist circumference (WC) and waist-to-height ratio (WHtR). Standard semen analysis was performed and serum levels of reproductive hormones were measured in 260 male partners of pregnant women at a university hospital andrology centres in Estonia. Quartile analysis revealed that all adiposity markers were negatively related to sex hormone-binding globulin and total testosterone levels. After adjustment for covariates a high BF%, WC and WHtR were negatively associated with total sperm count. The BF% was also negatively related to semen volume. These significant changes occurred from a BF% ≥ 23.4%, WC > 98 cm and WHtR > 0.54. Next to these changes the BMI was not related to sperm parameters. This study shows that semen quality is affected by central adiposity and confirms earlier findings that adiposity markedly changes serum sex hormone levels. Further studies are required to find out what is the best body composition marker showing most clearly the relationships between adiposity, semen characteristics and sex hormone levels.

    The aim of this study was to investigate the relations of basic semen parameters and reproductive hormones with alanine aminotransferase (ALT) and gamma-glutamyl transferase (GGT). In addition, to examine possible interaction between adiposity, alcohol consumption, and liver tests in relation to male reproductive health, standard semen analysis was performed and serum levels of reproductive hormones and liver tests were measured in 245 male partners of pregnant women at a University Hospital Andrology Centres in Estonia. Quartile analysis revealed that after adjustment for covariates GGT was negatively related to sperm concentration and total sperm count. These significant changes appeared from a GGT >35.5 U/L. Next to these changes ALT was not related to sperm parameters. Both enzymes, GGT and ALT, were not related to reproductive hormones. Alcohol consumption was positively related to GGT and in cases with elevated GGT alcohol use was negatively related to sperm concentration and total sperm count. Alcohol consumption was positively related to body mass index (BMI) and waist circumference (WC). Our findings also confirm results of previous studies that BMI and WC are associated positively with ALT and GGT. According to the study, increased GGT activity might represent a possible connection between adiposity, alcohol consumption, and semen quality.

    Full Text Available Sperm traits of 243 young bulls from Caracu (n=62, Gir (n=23, Guzerá (n=59 and Nellore (n=99 breeds, with 20-25 months of age, from the Breeding Program of Estação Experimental de Zootecnia de Sertãozinho, were analyzed. On the day of breeding soundness evaluation animals were weighed, the scrotal circumference was measured and the semen was collected by electroejaculation. The sperm motility, vigor and morphology were assessed and the animals were classified according to the andrological classification by points (CAP. No difference was observed among breeds for any seminal trait evaluated, although Nelore presented lower scrotal circumference average than the other breeds. When the animals were classified by body weight, it was observed that the heavier animals presented greater scrotal circumference, better seminal characteristics and, consequently, greater percentage of these animals were considered sexually mature comparing with the other body weight groups. It was concluded that the animals selected for post-weaning and reared on pasture from the taurine adapted breed Caracu and from the zebu breeds Gir, Guzerá and Nelore have proved able to reproduction at 23.2, 23.4, 22.7 and 22.8 months, respectively, corresponding to age which reached an average weight of 452, 422, 470 and 467 kg respectively.

    Full Text Available Erectile dysfunction (ED, metabolic syndrome (MetS, and hypogonadism are closely related, often coexisting in the aging male. Obesity was shown to raise the risk of ED and hypogonadism, as well as other endocrinological disturbances with impact on erectile function. We selected 179 patients referred for ED to our andrology unit, aiming to evaluate gonadotropins and estradiol interplay in context of ED, MetS, and hypogonadism. Patients were stratified into groups in accordance with the presence (or not of MetS and/or hypogonadism. Noticeable differences in total testosterone (TT and free testosterone (FT levels were found between patients with and without MetS. Men with MetS evidenced lower TT circulating levels with an increasing number of MetS parameters, for which hypertriglyceridemia and waist circumference strongly contributed. Regarding the hypothalamic-pituitary-gonadal axis, patients with hypogonadism did not exhibit raised LH levels. Interestingly, among those with higher LH levels, estradiol values were also increased. Possible explanations for this unexpected profile of estradiol may be the age-related adiposity, other estrogen-raising pathways, or even unknown mechanisms. Estradiol is possibly a molecule with further interactions beyond the currently described. Our results further enlighten this still unclear multidisciplinary and complex subject, raising new investigational opportunities.

    In the past, celiac disease (CD), or intolerance to gluten, was considered a rare disease of infancy characterized by chronic diarrhea with malabsorption and delayed growth. Besides the overt enteropathy, there are other clinic and subclinical forms which appear later in life. Target organs are not limited to the gut, but include liver, thyroid, skin and female and male reproductive systems. CD interference on reproduction is related to the multifactorial nature of the disease, whose pathological manifestations can be modulated, besides gluten, by different concurrent genetic and environmental factors. CD induces malabsorption with consequent deficiencies of micronutrients such as iron, folic acid and vitamin K, which are essential for organogenesis, and fat-soluble vitamins important for spermatogenesis. Regarding endocrine disorders, the deficiencies of specific trace elements on ovarian function could explain its involvement in the increased risk of female osteoporosis in CD patients. Affected males show a picture of tissue resistance to androgens; the increases of follicle-stimulating hormone and prolactin, not associated with infertility, may indicate an imbalance at hypothalamus-pituitary level, with general effects on health. Since reproductive alterations are reversible, adoption of a gluten-free diet supported by early diagnosis is important. Therefore, the detection of early biomarkers, such as deficiencies of vitamins and/or iron and andrological or endocrinological dysfunctions, should trigger timely strategies for prevention and treatment.

    Full Text Available Andrology is a constantly evolving discipline, embracing social problems like pedophilia and its pharmacological treatment. With regard to chemical castration, the andrologist may perform an important role as part of a team of specialists. At present, no knowledge is available regarding hormonal, chromosomal or genetic alterations involved in pedophilia. International legislation primarily aims to defend childhood, but does not provide for compulsory treatment. We reviewed international literature that, at present, only comprises a few reports on research concerning androgen deprivation. Most of these refer to the use of leuprolide acetate, rather than medroxyprogesterone and cyproterone acetate, which present a larger number of side effects. Current opinions on chemical castration for pedophilia are discordant. Some surveys confirm that therapy reduces sexual thoughts and fantasies, especially in recidivism. On the other hand, some authors report that chemical castration does not modify the pedophile’s personality. In our opinion, once existing legislation has changed, andrologists could play a significant role in the selection of patients to receive androgen deprivation therapy, due in part to their knowledge about its action and side effects.

Both poor water solubility and drug permeability have hindered the percutaneous absorption of silymarin. Formulation of silymarin into pluronic-lecithin organogel (PLO basis for topical skin delivery is the main aim of this work. Six different PLO formulations were prepared containing various pluronic to lecithin ratios using two cosolvent systems of ethyl alcohol and dimethyl sulfoxide. Formulation 2 (20% pluronic and 3% lecithin was found to be the optimal base for topical delivery of silymarin as it showed optimum pH, viscosity, drug content, and satisfactory in vitro silymarin permeation. The silymarin PLO formulation significantly relieved inflammatory symptoms of AD such as redness, swelling, and inflammation. These findings warrant the ability for application of these novel silymarin PLO formulations as a novel treatment for AD.

  18. Leukocytes and oxidative stress: dilemma for sperm function and male fertility

    Institute of Scientific and Technical Information of China (English)

    Ralf R Henkel

    2011-01-01

    Spermatozoa are constantly exposed to the interphase between oxidation through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions as being the only cells with such high polarization and exerting their functions outside the body, even in a different individual, the female genital tract, the membranes of these cells are chemically composed of an extraordinary high amount of polyunsaturated fatty acids. This in turn, renders them very susceptible to oxidative stress, which is defined as an imbalance between oxidation and reduction towards the oxidative status. As a result, ROS deriving from both leukocytes and the male germ cells themselves cause a process called 'lipid peroxidation' and other damages to the sperm cell. On the other hand, a certain limited amount of ROS is essential in order to trigger vital physiological reactions in cells, including capacitation or the acrosome reaction in sperm. The treatment of patients with antioxidants to compensate the oxidative status caused by oxidative stress is highly debated as uncontrolled antioxidative treatment might derail the system towards the reduced status, which is also unphysiological and can even induce cancer. This paradox is called the 'antioxidant paradox'.Therefore, a proper andrological diagnostic work-up, including the evaluation of ROS levels and the antioxidant capacity of the semen,has to be carried out beforehand, aimed at keeping the fine balance between oxidation and scavenging of vital amounts of ROS.

    Traditionally, the success of a researcher is assessed by the number of publications he or she publishes in peer-reviewed, indexed, high impact journals. This essential yardstick, often referred to as the impact of a specific researcher, is assessed through the use of various metrics. While researchers may be acquainted with such matrices, many do not know how to use them to enhance their careers. In addition to these metrics, a number of other factors should be taken into consideration to objectively evaluate a scientist's profile as a researcher and academician. Moreover, each metric has its own limitations that need to be considered when selecting an appropriate metric for evaluation. This paper provides a broad overview of the wide array of metrics currently in use in academia and research. Popular metrics are discussed and defined, including traditional metrics and article-level metrics, some of which are applied to researchers for a greater understanding of a particular concept, including varicocele that is the thematic area of this Special Issue of Asian Journal of Andrology. We recommend the combined use of quantitative and qualitative evaluation using judiciously selected metrics for a more objective assessment of scholarly output and research impact. PMID:26806079

  20. New Approaches to Boar Semen Evaluation, Processing and Improvement.

    2015-07-01

    The improvement of boar reproductive performance may be the next frontier in reproductive management of swine herd in Unites States, facilitated by better understanding of boar sperm function and by the introduction of new advanced instrumentation in the andrology field. Objective single ejaculate evaluation and individual boar fertility prediction may be possible by introducing automated flow cytometric semen analysis with vital stains (e.g. acrosomal integrity and mito-potential), DNA fragmentation analysis and biomarkers (ubiquitin, PAWP, ALOX15, aggresome) associated with normal or defective sperm phenotypes. Measurement of sperm-produced reactive oxygen species (ROS) is a helpful indicator of normal semen sample. Semen ROS levels could be managed by the addition of ROS-scavenging antioxidants. Alternative energy regeneration substrates and sperm stimulants such as inorganic pyrophosphate and caffeine could increase sperm lifespan in extended semen and within the female reproductive system. Such technology could be combined with timed sperm release in the female reproductive system after artificial insemination. Sperm phenotype analysis by the image-based flow cytometry will go hand in hand with the advancement of swine genomics, linking aberrant sperm phenotype to the fertility influencing gene polymorphisms. Finally, poor-quality ejaculates could be rescued and acceptable ejaculates improved by semen purification methods such as the nanoparticle-based semen purification and magnetic-activated sperm sorting. Altogether, these scientific and technological advances could benefit swine industry, provided that the challenges of new technology adoption, dissemination and cost reduction are met. PMID:26174914

    Increasingly accumulated results from randomized controlled trials and other clinical studies have demonstrated that male circumcision reduces the risks of acquisition and transmission of HIV, HPV, HSV-2, and other sexually transmitted infections, and thus has a potential role in preventing cervical cancer, penile cancer and prostate cancer. The prevalence of male circumcision in China is currently less than 5%. The clinical evaluation studies and randomized controlled trials of the Shang Ring device showed excellent safety profiles, extremely high acceptability, and satisfaction among the participants and service providers in Africa and China. Given the recent recommendations by the World Health Organization and the Joint United Nations Program on HIV/AIDS (UNAIDS), voluntary medical male circumcision should be promoted in China at the national level as an important alternative intervention to reduce reproductive tract infections and prevent both males and females from reproductive tract cancers. More emphasis is required on the studies of the long-term health benefits of male circumcision in uro-andrology.

    Full Text Available The purpose of this study is to investigate the prevalence rate and risk factors of depression in outpatients who were diagnosed with PE. Therefore, between September 2009 and September 2011, 1801 outpatients at andrology clinics were enrolled and consented to participate in our survey by completed a verbal questionnaire. It included the following: (1 demographic data (e.g., age, body mass index, (2 PE duration, medical history, and sexual history, (3 self-estimated intravaginal ejaculatory latency times, (4 the Zung Self-rating Depression Scale (SDS, and (5 the National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI and (6 the International Index of Erectile Function (IIEF-5. The results showed that a total of 1,206 patients were diagnosed with PE. The prevalence rate of depression in these PE patients was 26.78%. Depression was associated with PE duration, NIH-CPSI score, and IIEF-5 score. Risk factors for depression specifically included PE durations for 13–24, 25–60, or ≥61 months, CPSI scores of 15–30 or ≥31, and IIEF-5 scores <22. These findings suggested that several associated factors (PE duration, CPSI scores, and IIEF-5 scores were the risk factors of depression in men with PE.

    Full Text Available Abstract Background We present a case of primary infertility related to extreme cervical stenosis, a subset of cervical factor infertility which accounts for approximately 5% of all clinical infertility referrals. Case presentation A 37 year-old nulligravida was successfully treated with ovulation induction via recombinant follicle stimulating hormone (FSH and direct intraperitoneal insemination (IPI. Anticipating controlled ovarian hyperstimulation with in vitro fertilization/embryo transfer (IVF, the patient underwent hysteroscopy and cervical recanalization, but safe intrauterine access was not possible due to severe proximal cervical stricture. Hysterosalpingogram established bilateral tubal patency and confirmed an irregular cervical contour. Since the cervical canal could not be traversed, neither standard intrauterine insemination nor transcervical embryo transfer could be offered. Prepared spermatozoa were therefore placed intraperitoneally at both tubal fimbria under real-time transvaginal sonographic guidance using a 17 gage single-lumen IVF needle. Supplementary progesterone was administered as 200 mg/d lozenge (troche plus 200 mg/d rectal suppository, maintained from the day following IPI to the 8th gestational week. A singleton intrauterine pregnancy was achieved after the second ovulation induction attempt. Conclusions In this report, we outline the relevance of cervical factor infertility to reproductive medicine practice. Additionally, our andrology evaluation, ovulation induction approach, spermatozoa preparation, and insemination technique in such cases are described.

  5. How strict should specimen acceptance or rejection criteria be for diagnostic semen analysis? An opinion.

    2015-06-01

    Medical laboratory accreditation (previously by Clinical Pathology Accreditation UK Ltd and now by the United Kingdom Accreditation Service) has been integral to improving standards and service quality in the UK. With the recent introduction of the ISO15189 standard, all laboratories offering a clinical diagnostic service are required to demonstrate further improvement, with more emphasis on validation and assessment of the uncertainty levels associated with testing. This applies not only to 'bench testing', but also to the evidence-base for all pre-analytical and post-analytical procedures. To reduce the risk of external influences on andrology test results, semen sample rejection criteria were developed, including confirmation of patient identity, a strict time limit from sample production to testing, the use of toxicity-tested containers, a prescribed sexual abstinence and a need for complete sample collection. However, such criteria were originally developed by the World Health Organization in order to standardise analysis rather than reject testing outright, and should therefore be implemented with caution. Rejecting samples with normal semen parameters because they fail to meet some of the criteria as outlined above would be a waste of resources and adversely affect user (the person who requested or provided the sample) satisfaction. This document evaluates the evidence base underlying commonly used criteria for specimen rejection and suggests how they may be applied more pragmatically in order to improve efficiency and reduce the waste of resources.

    Full Text Available Abstract Background In male patients suffering from chronic pain, opioid administration induces severe hypogonadism, leading to impaired physical and psychological conditions such as fatigue, anaemia and depression. Hormone replacement therapy is rarely considered for these hypogonadic patients, notwithstanding the various pharmacological solutions available. Methods To treat hypogonadism and to evaluate the consequent endocrine, physical and psychological changes in male chronic pain patients treated with morphine (epidural route, we tested the administration of testosterone via a gel formulation for one year. Hormonal (total testosterone, estradiol, free testosterone, DHT, cortisol, pain (VAS and other pain questionnaires, andrological (Ageing Males' Symptoms Scale - AMS and psychological (POMS, CES-D and SF-36 parameters were evaluated at baseline (T0 and after 3, 6 and 12 months (T3, T6, T12 respectively. Results The daily administration of testosterone increased total and free testosterone and DHT at T3, and the levels remained high until T12. Pain rating indexes (QUID progressively improved from T3 to T12 while the other pain parameters (VAS, Area% remained unchanged. The AMS sexual dimension and SF-36 Mental Index displayed a significant improvement over time. Conclusions In conclusion, our results suggest that a constant, long-term supply of testosterone can induce a general improvement of the male chronic pain patient's quality of life, an important clinical aspect of pain management.

Being systemic, it might be possible to evaluate the extent of atherosclerosis from retinal vascular findings. We investigated the possible correlation between penile cavernosal artery blood flow and retinal vascular findings in patients with arteriogenic ED.Patients and methods: Sixty patients with ED were divided according to the peak systolic velocity (PSV in their penile cavernosal arteries into two groups; Group A included 30 patients with PSV less than 25 cm/sec, and Group B included 30 patients with PSV more than 35 cm/sec. Blood flow in the penile cavernosal artery was measured with color Doppler ultrasonography. All patients were assessed by ocular fundus examination under amydriatic conditions to evaluate retinal vascular atherosclerotic changes using Hyman’s classification.Results: Evidence of retinal vascular atherosclerotic changes was found in 19 patients (63.3% in Group A and in 10 patients (33.3% in Group B.Conclusions: Our study confirms the possibility of predicting penile arterial vascular status in patients with ED from their retinal vascular findings by using amydriatic simple, practical funduscopy.Keywords: erectile dysfunction, atherosclerosis, retinal vascular atherosclerosis

    Full Text Available Abstract Background Infertility is defined as inability of a couple to conceive naturally after one year of regular unprotected sexual intercourse. It remains a major clinical and social problem, affecting perhaps one couple in six. Evaluation usually starts after 12 months; however it may be indicated earlier. The most common causes of infertility are: male factor such as sperm abnormalities, female factor such as ovulation dysfunction and tubal pathology, combined male and female factors and unexplained infertility. Objectives The aim of this study is to provide the healthcare professionals an evidence-based management protocol for infertile couples away from medical information overload. Methods A comprehensive review where the literature was searched for "Management of infertility and/or infertile couples" at library website of University of Bristol (MetaLib by using a cross-search of different medical databases besides the relevant printed medical journals and periodicals. Guidelines and recommendations were retrieved from the best evidence reviews such as that from the American College of Obstetricians and Gynaecologists (ACOG, American Society for Reproductive Medicine (ASRM, Canadian Fertility and Andrology Society (CFAS, and Royal College of Obstetricians and Gynaecologists (RCOG. Results A simple guide for the clinicians to manage the infertile couples. Conclusions The study deploys a new strategy to translate the research findings and evidence-base recommendations into a simplified focused guide to be applied on routine daily practice. It is an approach to disseminate the recommended medical care for infertile couple to the practicing clinicians.

    Full Text Available Context: Lifestyle factors, like alcohol intake and cigarette smoking, have been reported to affect male fertility. Aims: To find out the specific impact of alcohol and smoking on semen quality of male partners of couples seeking treatment for primary infertility. Materials and Methods: From the semen samples analyzed in our andrology laboratory, results of 100 alcoholics and 100 cigarette smoker males were studied following WHO guidelines and compared with 100 strict nonalcoholic and nonsmoker males for presence of asthenozoospermia, oligozoospermia and teratozoospermia. Statistical Analysis: Data was analyzed by F- test using Microsoft Office Excel 2003. Results: Only 12% alcoholics and six per cent smokers showed normozoospermia compared to 37 % nonalcoholic nonsmoker males. Teratozoospermia, followed by oligozoospermia dominated alcoholics. Overall impact of asthenozoospermia and teratozoospermia, but not of oligozoospermia, was observed in smokers. Light smokers predominantly showed asthenozoospermia. Heavy alcoholics and smokers showed asthenozoospermia, teratozoospermia as well as oligozoospermia. Conclusions: Asthenozoospermia, the most common semen variable in our study, can be an early indicator of reduction in quality of semen. Alcohol abuse apparently targets sperm morphology and sperm production. Smoke-induced toxins primarily hamper sperm motility and seminal fluid quality. Progressive deterioration in semen quality is related to increasing quantity of alcohol intake and cigarettes smoked.

    This cross sectional study was carried out in the Infertility Unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2011 and June 2013. Eighty one (81) consecutive azoospermic male partner of married couple, aged 20-50 years with at least two years of subfertility and no known endocrinopathy and ejaculatory dysfunction were included in this study to find out their abnormal hormonal pattern. None of them had received any form of treatment within the last 3 months prior to hormonal evaluation. Men with hypertension, recent fever, chemo or radiation exposure were excluded from the study. Eight weeks interval two semen analyses were done in the Andrology Laboratory of above department following standard WHO guideline, 2004. Using standard ELISA technique, serum levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), testosterone and prolactin were measured/assayed/estimated. The results of this study demonstrated that 40 (49.4%) men had normal endocrine pattern against 51 (50.6%) with endocrinopathy. The former may be related to obstructive azoospermia, which needs further analyses. Both the increased FSH (>11.1mIU/ml) and LH (>7.6mIU/ml) were observed in 25 (30.9%) men, only elevated FSH (>11.1mIU/ml) in 9(11.1%), and only elevated LH (>7.6mIU/ml) in 7(8.6%). Low testosterone level (prolactin (<2.5ng/dl) in 5(6.2%).

    Aim: To analyse the possible effect of seasonal variation on semen parameters. Methods: The participants consisted of 1688 men attending the andrology laboratory between 1991 and 1997 for reduced fertility in the couple. Semen analysis was performed according to the WHO manual. The 84 individual months of the study period were each assigned to one of the three groups according to the average monthly outside temperature; Group A (temperature 13.3 ℃). Results: When comparing the different sperm parameters, the morphology was significantly better in Group C. However, when the smokers were analysed separately, this difference disappeared and significant seasonal variations were found in sperm density, total sperm count, motility and total motile sperm; they were deteriorated in the warmer season. In non-smokers, no such negative effect of increased temperature was observed. Conclusion: Sperm quality is influenced by seasonal factors.Increased environmental temperature, (maybe also light exposure) has an additional negative effect on the spermatogenesis in smokers, leading to reduced sperm quality in men with borderline fertility.

    In September 1994, the Kennedy Institute of Ethics Journal published a special issue on the ethics of embryo splitting or "cloning," which included papers originally prepared for a workshop on embryo splitting sponsored by the National Advisory Board on Ethics in Reproduction (NABER) and NABER's report, Human Cloning through Embryo Splitting. The impetus for the project was embryo-splitting research conducted by Drs. Jerry L. Hall, Robert J. Stillman, and others, at George Washington University and presented in October 1993 at a joint meeting of the American Fertility Society and the Canadian Fertility and Andrology Society. Media coverage at the time reported that the research had been approved by the university's formal review committees. However, it came to light in December 1994 that the researchers had not obtained approval from the university's institutional review board prior to conducting the research. Following a university investigation, the researchers were disciplined and instructed to destroy their data. The university also voluntarily forwarded the records of the incident to the Office for Protection from Research Risks at the National Institutes of Health. Dr. Hall resigned from George Washington University in September 1994. In the following postscript to her article on the ethics of embryo splitting (KIEJ, September 1994), Ruth Macklin discusses these events. The letters and memoranda that she cites were obtained from NIH through the Freedom of Information Act.

In Stavropol since 2007 has been organized the Men, s health protection service based on Regional clinical specialized uroandrological center. In uroandrological short stay surgical department successfully provides treatment in all forms of male genital in children and adult pathology with using minimally invasive methodics in short stay conditions and absence postsurgical complications. The operation rooms are staffed with all necessary equipment for carry out activities in full volume. All patients treated in urological department had sorted by anaesthesiological and somatic criterias.The main strategical directions are male reproductive health, pediatric urology-andrology, oncouroandrology. Human resources, high technology staff and intelligent work organization are fundamental for modern stationary substitute service. Human resource conception is urologist-andrologist – urologist – surgeon with laparoscopic, transurethral, microsurgery, reconstructive and plastic technique with endocrinology and psychiatric skills.Work indicators of medical center tells about high effectiveness and possibility of release profile urological beds for “big” surgical help and transfer male genital surgery on stationary substitute technologies.

    The authors studied the publications written by the staff of the University Department of Urology in Budapest, Hungary between 1946 and 1956. The collection was contributed on the occasion of Professor Babics's 10-year-long chairmanship. Over a period of 10 years, 214 papers were published by 15 urologists, including 3 books and 3 PhD theses; 16 papers were published in German, 22 in English, 2 in French, and 1 in Italian. The most frequent topic of the papers (26) was basic science (e.g., ureter motility, lymph circulation, intrarenal pressure condition). Other papers dealt with nephrology, artificial kidneys, TURP, and nephron-sparing renal surgery. Some articles examined various types of malignant tumors and benign prostatic hyperplasia, while 17 publications focused on the topic of andrology. Tuberculosis was also discussed by the authors. Despite political isolation, the communist dictatorship, poverty, the lack of health equipment, physicians educated before WWII with their work morality and hard work managed to perform contemporary clinical and basic scientific research.

    Full Text Available The advent of innovative techniques for addressing infertility has made for exciting times in the arena of andrology. The success of microTESE for retrieving sperm has enabled azoospermic men to have the opportunity to father biological children when it was previously impossible. The ability to offer a variety of assisted reproductive techniques that includes intracytoplasmic sperm injection has opened the door for couples with male factor infertility who were otherwise untreatable. With the multitude of options available to infertile couples, however, comes an unsurprising degree of controversy regarding what treatments should be offered and when. Complicating the picture is the question of if and when varicocele repair should be undertaken, and the financial implications of the treatment decisions that are made. The infertile couple with varicocele warrants careful consideration. The overall efficacy of varicocele repair as well as cost-effectiveness of repair compared to immediate microTESE in azoospermic men and assisted reproductive technology in men with suboptimal semen parameters will be reviewed.

    The aim of this study was to determine and examine the possible reasons for the difference in prostate cancer incidence between Asian men and North American men by literature review. Data regarding cancer incidence and mortality were obtained from the database of the International Agency for Research on Cancer (IARC). A literature review was conducted by studying related articles published in peer-reviewed journals such as the The New England Journal of Medicine, Journal of Clinical Oncology, A Cancer Journal for Clinicians and Asian Journal of Andrology. To evaluate the early diagnosis and survival rates, the mortality-to-incidence rate ratio (MR/IR) was calculated from the IARC data. By comparing prostate cancer data between Asian men and North American men, we found that differences in the incidence rate and MR/IR could be attributed largely to a lack of annual prostate cancer screening with serum prostate-specific antigen (PSA) in most Asian countries. It is likely that PSA screening also contributes significantly to the differences in prostate cancer mortality rates. Prostate cancer has the highest incidence rate among five common malignancies in Asian Americans. However, the MR/IR ratio of prostate cancer is the lowest among cancers. These data seem to further support the usefulness of PSA screening, even though the percentage of low risk cancers is greater in prostate cancer than in other cancers. The low incidence rate of prostate cancer does not reflect the actual statistics of this disease in Asia. The data from limited institutions in many Asian countries seem to bias the true incidence and mortality rates. To improve this situation, incorporating PSA screening for prostate cancer, as well as constructing a nationwide cancer registration system, will be helpful.

    The molecular diagnosis of Y-chromosomal microdeletions is a common routine genetic test which is part of the diagnostic workup of azoospermic and severe oligozoospermic men. Since 1999, the European Academy of Andrology (EAA) and the European Molecular Genetics Quality Network (EMQN) have been actively involved in supporting the improvement of the quality of the diagnostic assays by publication of the laboratory guidelines for molecular diagnosis of Y-chromosomal microdeletions and by offering external quality assessment trials. The present revision of the 2004 laboratory guidelines summarizes all the clinical novelties related to the Y chromosome (classic, partial and gene-specific deletions, genotype–phenotype correlations, methodological issues) and provides an update on the results of the quality control programme. These aspects also reflect the consensus of a large group of specialists present at a round table session during the recent Florence-Utah-Symposium on ‘Genetics of male infertility’ (Florence, 19–21 September, 2013). During the last 10 years the gr/gr deletion has been demonstrated as a significant risk factor for impaired sperm production. However, the screening for this deletion type in the routine diagnostic setting is still a debated issue among experts. The original basic protocol based on two multiplex polymerase chain reactions remains fully valid and appropriate for accurate diagnosis of complete AZF deletions and it requires only a minor modification in populations with a specific Y chromosome background. However, in light of novel data on genotype–phenotype correlations, the extension analysis for the AZFa and AZFb deletions is now routinely recommended. Novel methods and kits with excessively high number of markers do not improve the sensitivity of the test, may even complicate the interpretation of the results and are not recommended. Annual participation in an external quality control programme is strongly encouraged. The 12

    Discussions can be seen on the sexually -transmitted diseases related to male homosexuality in the Ming and Qing Dynasty.Based on the conceptions of yin and yang,medical professionals and moralists argued that male homosexuality leads to the intercourse between two yangs,on the top of which the hyperactive yang (kan-gyang)results in diseases.The andrology diseases referred to include turbidity (zhuobing),and malnutrition (gan-bing).The commonly seen diseases related to male homosexuality were vision -impairment,infertility,strength -exhaustion,in which the concept of male homosexual toxin (longyangdu)was particularly prominent.Medical pro-fessionals grounded their pathological reasoning on the basis of moral ideas,by which conclusions were reached prior to their proofs.This is an enlightening illumination of medical idealism.%与男色同性恋相关的疾病在明清时期有所讨论,诸医家及社会道德人士立足于阴阳观念,认为男男性行为是两阳相并,亢阳则诸疾丛至。所言男色男科病包括有浊病、疳病等,由男色引起的普通疾病包括有目损、艰嗣、体虚等,而“龙阳毒”的概念尤其引人瞩目。医家们用道德观念来推断病因,先下结论再找理由,为医学唯心主义提供了一个典型例证。

The etiology varies; in some cases, pneumoscrotum may be due to life-threatening disease like pneumothorax or Fournier gangrene. Despite this, pneumoscrotum is a rarely debated issue. We present two different cases of pneumoscrotum and a review of the literature. The first case report is about a 29 year old male patient affected by Duchenne syndrome who showed pneumoscrotum after cardiopulmonary resuscitation that was performed for asphyxic crisis and cardiovascular arrest. We carried out local puncture with an 18-gauge needle, and the pneumoscrotum was successfully solved. The second case report is about a 56 year old male with pneumoscrotum due to Fournier gangrene who underwent radical exeresis of all necrotic tissues and drainage. This is why most of the scrotal skin and all of the penis skin were removed; as a result, the testicles, epididymis, and cavernosa corpora were externalized. On postoperative day one, the patient was feverless and underwent hyperbaric chamber therapy. No postoperative complications occurred. Accurate evaluation of the pneumoscrotum is always needed. Despite the benign course of most of the clinically evident pneumoscrotum cases, this condition should never be underestimated.

    Aim:To test the hypothesis that season affects the semen quality of swamp buffalo (Bubalus bubalis) bulls used for artificial insemination (AI) under tropical conditions in Thailand, as it does in Bos taurus and Bos indicus. Methods: Clinical and andrological examinations, and monitoring of semen production and quality were carried out on five mature, healthy swamp buffalo AI bulls in Thailand from July 2004 to the end of June 2005. Sperm output, motility, morphology and plasma membrane integrity (PMI) were compared between three seasons of the year (rainy, I.e. July-October; winter, I.e. November-February; and summer, I.e. March-June) with distinct ambient temperature and humidity. Results: All bulls were diagnosed as clinically healthy and with good libido throughout the study. Ejaculate volume, pH, sperm concentration, total sperm number and initial sperm motility did not differ between seasons, whereas PMI and the relative proportion of morphologically normal spermatozoa were highest in summer and lowest in winter (P < 0.05). Buffalo age, week of collection and season influenced sperm morphology (P < 0.05-0.001). Among morphological abnormalities,only proportions of tail defects were affected by season, being highest in the rainy season and lowest in summer (P<0.001). In conclusion, climatic changes did not seem to largely affect semen sperm output or viability. Although the proportions of PMI and tail abnormalities were affected by season, they were always below what is considered unacceptable for AI bull sires. Conclusion: Seasonal changes did not appear to cause deleterious changes in sperm quality in swamp buffalo AI-sires in tropical Thailand.

    Semen storage is now routinely offered to men of reproductive age who are diagnosed with malignant disease and who require surgical or chemotherapeutic treatments that have a significant risk of leaving them sterile or subfertile. There is a perception by the public at large and professionals in the field that this is a routine and simple process. Yet, semen storage for such men requires a number of unique skills from a multidisciplinary team of oncologists, nurses, counsellors and scientists (andrologists or embryologists) in order to provide a quality service to the patient. All too often it is seen as 'just another branch' of assisted conception treatment but there are sufficient unique issues for it to be considered a specialty in its own right. In the absence of professional guidelines to outline 'best practice', the British Andrology Society invited interested parties to attend a one-day workshop. This was designed as an interactive workshop for all those involved in the process of semen storage, be they clinicians, nurses, counsellors and scientific staff from either the disciplines of reproductive medicine or oncology. It was intended to examine the process of semen storage for such patients from the point of initial diagnosis, through the process of banking semen samples, to the point at which they are either used in treatment or are discarded. The programme was designed to promote maximum interaction between the speakers and the audience and between those from different specialties and disciplines so that they may learn from each other, developing and improving the service that is provided to these men.

Therefore, the goal of this study was to investigate the relationship between the physical and morphological assessment of semen cryopreserved in Central with the number of doses per pregnancy and pregnancy rate by the number of doses used. Four Nelore bulls were challenged in 557 heifers and one bull in 156 Red Angus cows, both Nellore. For number of insemination doses required per pregnancy, tended to correlate significantly with lower amount of pathologies (0.053, P> 0.05, with no significant correlation between sperm motility (0.433, P> 0.05, spermatic vigor (0.932 , P> 0.05, concentration (0.111, P> 0.05, number of viable sperm (0.637, P> 0.05, percentage of major diseases (1, P> 0.05 and percentage of pathologies Total (0.623, P> 0.05.

    Full Text Available OBJECTIVE: The growing consensus on the negative impact of cigarette smoking on fertility prompted us to compare the rate of sperm respiration in smokers and non-smokers. MATERIALS AND METHODS: Semen samples from 20 smokers and 58 non-smokers consulting at the andrology laboratory for fertility evaluation were used. Smoking was defined as consumption of at least a half a pack per day. A phosphorescence analyzer that measures O2 concentration in sperm suspensions as function of time was used to determine the rate of respiration. In a sealed vial, the rate of sperm respiration (k was defined as -d[O2]/dt; where [O2] was obtained from the phosphorescence decay rate of a palladium phosphor. [O2] in solutions containing sperm and glucose declined linearly with time, showing the kinetics of O2 consumption was zero-order. Inhibition of O2 consumption by cyanide confirmed the oxidations that occurred in the sperm mitochondrial respiratory chain. RESULTS: There were no differences (p > 0.28 between smokers and non-smokers for ejaculate volume, motility, concentration, normal morphology, viability and hypo-osmotic swelling test. The rate (mean ± SD, in µM O2/min/108 sperm of sperm mitochondrial O2 consumption in the smokers was 0.96 ± 0.58 and in the non-smokers 1.39 ± 0.67 (p = 0.004. CONCLUSIONS: The rate of sperm respiration was significantly lower in smokers. This negative impact of cigarette smoking on sperm aerobic metabolism may, in part, explain the lower rate of fertility in smokers.

    The problem of the interference of celiac disease (CD) with the male reproductive system is made evident both by the recognized adverse effects on female reproduction and by the multifactorial nature of the disease. It is important to consider CD as a multifactorial condition since its diverse effects can be modulated, besides gluten, by different concurrent genetic and environmental factors. The male CD patient has a greater risk of infertility and other reproductive disturbances, as well as a greater incidence of hypoandrogenism. In this paper the problems of CD associated to endocrine disorders and to deficiencies of micronutrients are discussed. Affected males show a picture of tissue resistance to androgens. Moreover, attention should be paid to increases of FSH and prolactin; these are not associated to infertility and/or impotence, but they may indicate an imbalance at hypothalamus-pituitary level, with general effects on health: an example is the increased risk of male osteoporosis in CD patients. Hormone alterations are reversible upon start of the gluten-free diet, emphasizing the importance of early diagnosis; this should be performed in the case of clinical suspicion, e.g., unexplained hypoandrogenism. As regards nutritional aspects, the folic acid deficiency of CD can affect rapidly proliferating tissues, such as the embryo and the seminiferous epithelium. More attention should be paid to deficiencies of fat-soluble vitamins, such as A and E, observed in CD. Vitamin A is important for Sertoli cell function as well as for early spermatogenetic phases. Vitamin E supports the correct differentiation and function of epidydimal epithelium, spermatid maturation and secretion of proteins by the prostate. Therefore, CD male patients should be considered as vulnerable subjects; thus, the detection of early biomarkers of andrological or endocrinological dysfunctions should trigger timely strategies for prevention and treatment.

    The aim of the study was to evaluate the efficiency, after 1 year, of combined use of psychodynamic psychotherapy integrating virtual reality (VR) for the treatment of erectile dysfunction (ED) and premature ejaculation (PE) in 160 heterosexual males who had neither any prior sexual therapy nor had made use (either before, during or after therapy) of any specific pharmaceuticals for the treatment of primary sexual dysfunction. All subjects had given their informed consent. After a clinical diagnosis in an andrologic center, 50 presumably psychological ED (average age 43.7 years), 60 mixed ED (53.9 years) and 50 primary PE (39 years) who suffered these problems over 6 months were undergoing a cycle of 12 sessions, over a 25-week period, of psychotherapy, integrating an audio CD and helmet with miniature television screens that projected specially designed CD-ROM program on the ontogenetic development of male sexual identity. The clinical follow up was done after 6 and 12 months after the cycle. After one year, the overall partial (two times out of three) and complete positive response rate for psychological ED was 75%, for mixed ED was 47% and for PE was 54%. We considered drop-out cases as only before the 7th session of the treatment cycle, the drop-outs after session 7 and the patients that did not show up for follow-up are counted as negative results. Two patients reported nausea and one, vertigo during the first 15-min virtual reality experience. Considering the particular way that full-immersion virtual reality involves the subject who experiences it, we hypothesized that this methodological approach could speed up the therapeutic process. The evidence that positive results persist over time allows us to hypothesize that certain changes in cerebral function can be possible and that these changes are correlated to favorable sexual performance in the male.

    The incidence of male reproductive failure leading to infertility, whether due to delayed parenthood, environmental issues, genetic factors, drugs, etc., is increasing throughout the world. The diagnosis and prognosis of male subfertility have become a challenge. While the basic semen assessment has been performed for many years, a number of studies question the value of the traditional semen characteristics. This is partly due to inadequate methods and standardization, limited knowledge of technical requirements for quality assurance, and an incomplete understanding of what clinical information a semen assessment can provide. Laboratories currently performing semen and endocrine assessment show great variability. The World Health Organization (WHO) manual for the evaluation of semen has been the core of andrology and fertility evaluation that has helped in further development of this field over many years. These include the physical appearance of the ejaculate, assessments of sperm count, motility, vitality, morphology, and functional aspects of the sperm and semen sample. These tests also include male endocrine profile, biochemical evaluation of the semen, detection of antisperm antibodies in serum, the use of computer-aided sperm analysis (CASA), sperm DNA integrity, and its damage due to oxidative stress. Assisted reproductive techniques (e.g., IVF, ICSI) have shown great success but are too expensive. Further development in this field with newer techniques and extensive training/instructions can improve accuracy and reduce variability, thus maintaining the quality and standards of such an evaluation. There is an urgent need to have standardized training centers and increased awareness in this area of men's health for reproductive success.

    Full Text Available Objective. The aim of this study was to evaluate the prevalence of most common mutations and intron 8 5T (IVS8-5T polymorphism of CFTR gene in Italian: a azoospermic males; b non azoospermic subjects, male partners of infertile couples enrolled in assisted reproductive technology (ART programs. Material and methods. We studied 242 subjects attending our Andrology Unit (44 azoospermic subjects and 198 non azoospermic subjects, male partners of infertile couples enrolled in ART programs. Semen analysis, molecular analysis for CFTR gene mutations and genomic variant of IVS8-5T polymorphic tract, karyotype and chromosome Y microdeletions, hormonal profile (LH, FSH, Testosterone and seminal biochemical markers (fructose, citric acid and L-carnitine were carried out. Results. The prevalence of the common CFTR mutations and/or the IVS8-5T polymorphism was 12.9% (4/31 cases in secretory azoospermia, while in obstructive azoospermia was 84.6% (11/13 cases; in these, the most frequent mutations were the F508del, R117H and W1282X. Regarding the non azoospermic subjects, the prevalence of the CFTR and/or the IVS8-5T polymorphism was 11.1% (11/99 cases in severe dyspermia, 8.1% (6/74 cases in moderate dyspermia and finally 4.0% (1/25 cases in normospermic subjects. Conclusions. This study confirms the highly significant prevalence of CFTR mutations in males with bilateral absence of the vas deferens or ejaculatory ducts obstruction compared with subjects with secretory azoospermia. Moreover, the significant prevalence of mutations in severely dyspermic subjects may suggest the possible involvement of CFTR even in the spermatogenic process. This could explain the unsatisfactory recovery of sperm from testicular fine needle aspiration in patients affected by genital tract blockage.

    The aim of this work was to evaluate the effects of ROS scavenger supplementation in human semen samples undergoing cryopreservation procedures.After screening out andrological pathologies, we selected 25 male partners of infertile couples with the following semen profile: volume >/= 2.0 ml, normal viscosity, sperm count >/=20 x 10(6)/ml, straight progressive motility (classes 1 and 2) >/= 40% (Mazzilli, Rossi, Delfino and Nofroni (1999) Andrologia 31: 187-194), atypical forms semen analysis and the Hypoosmotic Viability Test (HVT) were carried out; the samples were then divided into 4 aliquots. The first was untreated as a control; 200 U/ml of superoxide dismutase (SOD) was added to the second, 200 U/ml of catalase to the third and both SOD (100 U/ml) and catalase (100 U/ml) were added to the fourth aliquot. Each aliquot was mixed (v/v) with TEST yolk buffer freezing medium (Irvine Scientific) and then frozen at -196 degrees C. The percent recovery of progressive motile and swollen spermatozoa was evaluated after thawing.No significant variation in the recovery of progressive motility was seen in the aliquots with added SOD or catalase alone, compared to the control group. On the other hand, a significant improvement in sperm parameter recovery was seen in the aliquot with both SOD and catalase supplementation; perhaps because of their combined and simultaneous action on superoxide anion and hydrogen peroxide. These results suggest that, in some selected cases, SOD and catalase supplementation can contribute greatly to the prevention of sperm membrane lipid peroxidation by ROS and thus allow good sperm parameter recovery after freezing-thawing procedures.

    Inflammatory disease such as prostatitis and prostatovesiculitis, can affect the fertility potential of the male population. In this study, the Authors tested the therapeutical efficacy of a second generation quinolone, enoxacin, in patients suffering from vesicular and/or prostatic inflammations. This drug has been shown to diffuse into the prostatic fluid, achieving therapeutical concentrations either in acute or chronic pathological conditions. Thirty infertile patients referring to our Andrology Center and showing seminal signs (leukocytes, abnormal sperm forms, chemical and physical alterations, etc) of genital tract inflammations were found to have positive sperm culture for enoxacin-sensitive strains. Further investigations (echotomography) showed that they were affected by prostatic and/or vesicular subacute chronic inflammations. The mean age was 32.2 (range 20-36) ys. All the patients discontinued any previous treatment for at least 90 days. Enoxacin was administered at the dose of 300 mg b.i.d. for two cycles of 10 days each, with intervals of 20 days. At the beginning and at the end of the treatment (days 0 and 60), semen analysis and culture were performed. A paired-T test was employed for the statistical evaluation of data. 26.6% of patients ad an altered fluidification before treatment. Only 10.0% of them showed the same sign after treatment. A condition of hyperviscosity was present in 50% and 16.6% of patients before and after treatment respectively. Likewise, an elevated number of leukocytes (greater than 10(6)/ml) occurred in the ejaculates of 43.3% of patients and in 23.3% after enoxacin treatment. Enoxacin treatment was efficacious in 89.2% of cases, in presence of either Gram positive or Gram negative bacteria.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:2529639

    Men's health concerns have evolved from the traditional andrology and male sexual health to a more holistic approach that encompasses male psychological, social and physical health. The poor state of health in men compared to their female counterparts is well documented. A review of the epidemiological data from Malaysia noted a similar trend in which men die at higher rates in under 1 and above 15 years old groups and most disease categories compared to women. In Malaysia, the main causes of death in men are non-communicable diseases and injuries. Risk factors, such as risk-taking behaviour, smoking and hypertension, are prevalent and amenable to early interventions. Erectile dysfunction, premature ejaculation and prostate disorders are also prevalent. However, many of these morbidities go unreported and are not diagnosed early; therefore, opportunities for early intervention are missed. This reflects poor health knowledge and inadequate health-care utilisation among Malaysian men. Their health-seeking behaviour has been shown to be strongly influenced by family members and friends. However, more research is needed to identify men's unmet health-care needs and to develop optimal strategies for addressing them. Because the Malaysian population is aging and there is an increase in sedentary lifestyles, optimizing men's health will remain a challenge unless effective measures are implemented. The existing male-unfriendly health-care system and the negative influence of masculinity on men's health behaviour must be addressed. A national men's health policy based on a male-friendly approach to health-care delivery is urgently needed to provide a framework for addressing these challenges.

    Chronic prostatitis ( CP ) is a common disease of urology and andrology. It seriously impacts the physical and mental health of the patients, because it frequently recured and can not be cured completely. According to the clinical characteristic of CP, we found that the pathogenesises of traditional Chinese medicine ( TCM ) are closely related to liver ( Gan ). Because the liver channel named in TCM is distributed at external genitalia area, Qi stagnation of liver, dampness-heat of liver channel and coldness accumulation in liver channel are the main pathogenesises of CP. Thus the treatment of CP with TCM should be aimed at liver. The treatment principles of CP in TCM include relieving depressing of liver, relieving stagnation of liver, dispelling the heat of liver, nourishment of liver blood, warming channel of liver, etc. Moreover, psychological counseling is also a treatment method for patients with CP. There is a clincial significance to treat patients with CP from liver in clinical practice of TCM.%慢性前列腺炎是泌尿男科的常见多发病,其病程迁延难愈、常反复发作,严重影响着患者的身心健康.根据慢性前列腺炎的临床特点,其发病与肝的关系尤为密切.因肝司阴器,肝郁气滞、肝经湿热、寒凝肝脉是引起慢性前列腺炎的重要病机.治疗慢性前列腺炎应责之于肝,治法包括疏肝气、解肝郁、清肝热、养肝血、温肝经等,同时应重视对患者的心理疏导.从肝论治慢性前列腺炎有着重要的临床意义.

    Full Text Available Wayne JG HellstromChief, Section of Andrology, Department of Urology, Tulane University School of Medicine, New Orleans, LA, USAAbstract: Premature ejaculation (PE is a common problem in men worldwide. It has a significant impact on affected men and their partners in terms of self-esteem, dissatisfaction with their sexual relationships, personal distress, and interpersonal difficulty. Psychological therapies may achieve short-term improvements, but there are limited data on the long-term success of these methods. Oral therapy with long-acting selective serotonin reuptake inhibitors (SSRIs improves intravaginal ejaculatory latency time (IELT, but these agents are designed to be administered daily and may be associated with unwanted sexual side effects and withdrawal symptoms upon abrupt discontinuation. Dapoxetine is a short-acting SSRI that can be taken as needed (prn by men with PE. It has been studied in five separate multicenter, randomized, double-blind, placebo-controlled trials involving more than 6000 men with PE. In four studies that evaluated IELT as an endpoint (N = 4843, dapoxetine 30 and 60 mg prn achieved statistically significant increases in IELT versus placebo. Dapoxetine also showed statistically significant improvements in perceived control over ejaculation, PE-related personal distress, and other patient-reported outcomes in all five trials. Dapoxetine treatment is generally well-tolerated, with low incidences of discontinuation syndrome, sexual dysfunction, and treatment-emergent mood symptoms. The most common adverse events with dapoxetine included nausea, diarrhea, headache, dizziness, and somnolence.Keywords: dapoxetine, discontinuation syndrome, premature ejaculation, selective serotonin reuptake inhibitor

    Peyronie’s disease (PD) is a chronic inflammatory disease involving the tunica albuginea of the penis. Erectile dysfunction (ED) is a possible invalidating symptom of PD. The aim of this study was to evaluate the prevalence, psychological impact, and risk factors of ED in patients with PD. The study was conducted by carrying out a retrospective analysis of the clinical records of 309 patients with PD who visited our andrology clinic. All patients underwent the following tests: body mass index, common blood tests and hormone assays, questionnaire for erectile function assessment, dynamic penile color Doppler ultrasonography, imaging of the penis at maximum erection with photographic poses according to Kelâmi, psychosexual impact evaluation with PD Questionnaire (symptom bother score), evaluation of depression symptoms with the Patient Health Questionnaire-9, and evaluation of the intensity of penile pain with the pain intensity numeric rating scale. ED was observed in 37.5% of the cases. We divided the cases into two groups: group A (PD + ED), 116 cases, and group B (PD without ED), 193 cases. After multivariate analysis, we concluded that the following comorbidities are independent risk factors for ED: dyslipidemia, obesity, chronic prostatitis, benign prostatic hyperplasia, and autoimmune diseases. A depressive disorder was observed in 62.4%, and it was more frequent in patients with PD + ED (91.37% versus 45.07% group B). Sexual bother was greater in group A compared with group B (9.7 versus 7.6). Intensities of depressive symptoms and sexual bother were significantly higher compared with cases with no curvature when the bend angle was ≥30°. Our study confirms that an integrated psychological support with medical treatment is needed in patients with PD. PMID:27486570

    Full Text Available Digito-rectal examination (DRE of the prostate provides useful information on the state of prostate growth and on the presence of suspected peripheral nodules. The aim of this study is to describe the clinical and biochemical correlates of finding an enlarged prostate size at DRE in subjects with sexual dysfunction (SD. A consecutive series of 2379 patients was retrospectively studied. The analysis was focused on a subset of subjects (n = 1823; mean age 54.7 ± 11.4 selected for being free from overt prostatic diseases. Several parameters were investigated. After adjusting for confounders, the presence of an enlarged prostate size at DRE was associated with a higher risk of metabolic syndrome (HR = 1.346 (1.129-1.759; P = 0.030, type 2 diabetes mellitus (HR = 1.489 (1.120-1.980; P = 0.006, increased LDL cholesterol (>100 mg dl−1 ; HR = 1.354 (1.018-1.801; P = 0.037 and increased mean blood pressure (BP values (HR = 1.017 (1.007-1.027 for each mmHg increment; P = 0.001. Accordingly, enlarged prostate size was also associated with a higher risk of arteriogenic erectile dysfunction (ED, as well as with other andrological conditions, such as varicocele and premature ejaculation (PE. PSA levels were significantly higher in subjects with enlarged prostate size when compared to the rest of the sample (HR = 3.318 (2.304; 4.799 for each log unit increment in PSA levels; P < 0.0001. Arteriogenic ED, according to different criteria, was also associated with increased PSA levels. In conclusion, our data support the need to examine prostate size either by clinical (DRE or biochemical (PSA inspection in subjects with SD, in order to have insights into the nature of the SD and the metabolic and cardiovascular (CV background of the patient.

    Abnormal foetal testis development has been proposed to underlie common disorders of the male reproductive system such as cryptorchidism, hypospadias, reduced semen quality and testicular germ cell tumour, which are regarded as components of a 'testicular dysgenesis syndrome'. The increasing trends and geographical variation in their incidence have been suggested to result from in utero exposure to environmental chemicals acting as endocrine disruptors. In rodents, the anogenital distance (AGD), measured from the anus to the base of genital tubercle, is a sensitive biomarker of androgen exposure during a critical embryonic window of testis development. In humans, several epidemiological studies have shown alterations in AGD associated with prenatal exposure to several chemicals with potential endocrine disrupting activity. However, the link between AGD and androgen exposure in humans is not well-defined. This review focuses on the current evidence for such a relationship. As in rodents, a clear gender difference is detected during foetal development of the AGD in humans which is maintained thereafter. Reduced AGD in association with clinically relevant outcomes of potential environmental exposures, such as cryptorchidism or hypospadias, is in keeping with AGD as a marker of foetal testicular function. Furthermore, AGD may reflect variations in prenatal androgen exposure in healthy children as shorter AGD at birth is associated with reduced masculine play behaviour in preschool boys. Several studies provide evidence linking shorter AGD with lower fertility, semen quality and testosterone levels in selected groups of adults attending andrology clinics. Overall, the observational data in humans are consistent with experimental studies in animals and support the use of AGD as a biomarker of foetal androgen exposure. Future studies evaluating AGD in relation to reproductive hormones in both infants and adults, and to gene polymorphisms, will help to further delineate

Traditionally, injectable testosterone esters have been used for treatment, but they generate supranormal testosterone levels shortly after the 2- to 3-weekly injection interval and then testosterone levels decline very rapidly, becoming subnormal in the days before the next injection. The rapid fluctuations in plasma testosterone are subjectively experienced as disagreeable. Testosterone undecanoate is a new injectable testosterone preparation with a considerably better pharmacokinetic profile. After 2 initial injections with a 6-week interval, the following intervals between two injections are almost always 12-weeks, amounting eventually to a total of 4 injections per year. Plasma testosterone levels with this preparation are nearly always in the range of normal men, so are its metabolic products estradiol and dihydrotestosterone. The “roller coaster” effects of traditional parenteral testosterone injections are not apparent. It reverses the effects of hypogonadism on bone and muscle and metabolic parameters and on sexual functions. Its safety profile is excellent due to the continuous normalcy of plasma testosterone levels. No polycythemia has been observed, and no adverse effects on lipid profiles. Prostate safety parameters are well within reference limits. There was no impairment of uroflow. Testosterone undecanoate is a valuable contribution to the treatment options of androgen deficiency.Keywords: testosterone treatment, testosterone undecanoate, pharmacokinetic profile, clinical efficacy, side effects

IVDs were categorized into two types: IVD-B has a tail used for fixing to the vas deferens (fixed wing whereas IVD-A does not. A multicenter prospective randomized controlled clinical trial was conducted in China. The study was comprised of 1459 male volunteers seeking vasectomy who were randomly assigned to the IVD-A (n = 487, IVD-B (n = 485 or NSV (n = 487 groups and underwent operation. Follow-up included visits at the 3 rd -6 th and 12 th postoperative months. The assessments of the subjects involved regular physical examinations (including general and andrological examinations and semen analysis. The subjects' partners also underwent monitoring for pregnancy by monthly interviews regarding menstruation and if necessary, urine tests. There were no significant differences in pregnancy rates (0.65% for IVD-A, 0 for IVD-B and 0.21% for NSV among the three groups (P > 0.05. The cumulative rates of complications at the 12 th postoperative month were zero, 0.9% and 1.7% in the three groups, respectively. In conclusion, IVD male sterilization exhibits a low risk of long-term adverse events and was found to be effective as a male sterilization method, similar to the NSV technique. IVD male sterilization is expected to be a novel contraceptive method.

    Full Text Available Introduction: Penile implant patients are required to remain in the hospital after the operation for monitoring, antibiotic and analgesia administration. Cost containment, however, has resulted in the increased use of ambulatory surgery settings for many surgical procedures. Few studies have studied the feasibility of performing penile prosthesis insertion in an outpatient setting. The results are controversial and nowadays, in the most of centers that deal with prosthetic surgery, patients are still hospitalized. Aim: The aim of our investigation was to compare the feasibility of the performance as well as the complication profiles of penile implant surgery performed in an in-patient and an outpatient setting at a single center by a single surgeon. Methods: From January 2009 to June 2014, 50 patients of the same uro-andrological unit underwent penile prosthesis implantation performed by a single surgeon (N.M.. Twenty implantations were performed in an ambulatory day surgery setting. Main outcome measures: Effectiveness and costs of outpatient setting versus the in-patient setting of the penile prosthesis surgery. Results: There were some differences between the two groups in the intra-operative parameters, such as, operating time. Time lost from work was similar in both groups approximating 14 days. The mean number of analgesic pills ingested by the patients post-operatively was similar in both groups, averaging just under 25 pills per patient. There weren’t post-operative complications in the outpatient group. Cost were 17% less in outpatient clinic. Conclusions: The outpatient setting for this surgery is safe and effective even in patients with comorbidities or in case of secondary procedures. Costs are reduced by 17%.

    During the period January 1, 1991 through December 31, 1995, 258 patients, in whom motile sperm counts for insemination (postwash, processed) were 10.0 million motile sperm or less were seen in the andrology unit for sperm washing and intrauterine insemination (IUI). No significant female factors were noted on history; all female partners had patent Fallopian tubes and were ovulatory spontaneously or were treated by the referring gynecologist with clomiphene citrate, human menopausal gonadotropin (hMG), or follicle-stimulating hormone (FSH) ovulation induction in both anovulatory or ovulatory women. Of the total of 258 patients, 15 achieved a pregnancy in 284 cycles of IUI in which the inseminating motile-count was IUI in this group was 0.61 (+/-0.29) million sperm, with a range of 0.19-0.95 million motile sperm. The initial motile count was 2.97 (3.2) million sperm, with a range of 0.2-12.81 million sperm. With inseminating motile counts of 1.0-10.0 million motile sperm, there were 83 pregnancies after 467 cycles of IUI, resulting in a monthly f of 17.8%. The mean (+/-SD) motile count for IUI in this group was 4.9 (+/-2.7) million motile sperm with a range of 1.0-9.9 million motile sperm. The initial sperm count in this group was 10.9 million (+/-7.1), with a range of 1.1-23.7 million motile sperm. These data suggest that acceptable pregnancy rates can be achieved with IUI, even in severely oligozoospermic specimens. Intrauterine insemination is less invasive and less costly than other assisted reproductive techniques. These data are supportive of IUI prior to attempting other more invasive and potentially costly reproductive technologies. PMID:9283959

    The incidence of male reproductive failure leading to infertility, whether due to delayed parenthood, environmental issues, genetic factors, drugs, etc., is increasing throughout the world. The diagnosis and prognosis of male subfertility have become a challenge. While the basic semen assessment has been performed for many years, a number of studies question the value of the traditional semen characteristics. This is partly due to inadequate methods and standardization, limited knowledge of technical requirements for quality assurance, and an incomplete understanding of what clinical information a semen assessment can provide. Laboratories currently performing semen and endocrine assessment show great variability. The World Health Organization (WHO) manual for the evaluation of semen has been the core of andrology and fertility evaluation that has helped in further development of this field over many years. These include the physical appearance of the ejaculate, assessments of sperm count, motility, vitality, morphology, and functional aspects of the sperm and semen sample. These tests also include male endocrine profile, biochemical evaluation of the semen, detection of antisperm antibodies in serum, the use of computer-aided sperm analysis (CASA), sperm DNA integrity, and its damage due to oxidative stress. Assisted reproductive techniques (e.g., IVF, ICSI) have shown great success but are too expensive. Further development in this field with newer techniques and extensive training/instructions can improve accuracy and reduce variability, thus maintaining the quality and standards of such an evaluation. There is an urgent need to have standardized training centers and increased awareness in this area of men's health for reproductive success. PMID:27056346

    The aim of this study was to evaluate the possible association between cardiometabolic risk factors accumulation and vitamin D status in a cohort of Italian normal weight and overweight male children. 108 boys enrolled in an andrological health prevention project underwent physical examination, anthropometric measurements, and fasting blood sampling. Serum blood glucose, HDL-cholesterol, triglycerides, parathyroid hormone, and 25-hydroxyvitamin D (25(OH)D) were measured. Cardiovascular risk factors were defined according to the National Cholesterol Education Program Adult Treatment Panel III modified for age. Lean and overweight subjects differed in terms of waist circumference (P < 0.001), HDL-cholesterol (P = 0.001), triglycerides (P = 0.001), systolic blood pressure (P < 0.001) and diastolic blood pressure (P = 0.002). Both groups had similar mean 25(OH)D levels (P = 0.160) and were below the sufficiency threshold: indeed only 24 % of normal weight had 25(OH)D ≥30 ng/ml, and even less in the overweight/obese group (8 %, P = 0.03 vs. normal weight). A significant accumulation of risk factors in course of 25(OH)D insufficiency was detected in both the whole cohort and in the normal weight group (P = 0.003 and P = 0.04, respectively) with odd ratios of 1.31 (1.16-1.49 95%CI) and 1.41 (1.18-1.69 95%CI), respectively. In course of vitamin D deficiency, the odd ratios were 2.24 (1.34-3.77 95%CI, P = 0.003) in the whole cohort and 2.40 (1.27-4.82 95%CI, P = 0.03) in lean subjects. We reported a considerable occurrence of cardiovascular risk factors in course of hypovitaminosis D in overweight/obese boys and even in lean subjects, which normally would not have been further evaluated by considering the sole BMI-related parameters. In this regard, 25(OH)D levels appear as a potential discriminating parameter able to identify male children at higher health risk.

About 10% of follicular thyroid carcinoma shows multiple metastases: lung and bone are the most common sites of metastasis. Renal involvement from thyroid primary cancer is very rare with incidence of 4.5%–5.9%.Purpose: We report the first laparoscopic conservative treatment of renal metastasis from thyroid cancer. This is a new and useful approach in order to delay malignant disease progression and to reduce the surgical discomfort of the patient.Patients and methods: We present the case of a 67-year-old woman, undergoing total thyroidectomy for follicular thyroid cancer with bone and lung metastasis. During adjuvant radiometabolic treatment, renal metastasis was diagnosed. Renal metastasis showed high metabolic activity, reducing the effectiveness of radioiodine therapy for secondary lesions. For this reason, we performed a laparoscopic simple enucleation of the single renal metastasis using extraperitoneal access and a clampless procedure.Results: The excision of the renal lesion improved the effectiveness of adjuvant radioiodine therapy: two months after surgery, the patient underwent adjuvant radiometabolic treatment with iodine-131 (150 mCi and the following whole body scan showed only a small uptaking area at the level of the vertebral metastasis. The lung micrometastases were not detectable. At 36 months follow-up, malignant disease was clinically stable and well controlled.Conclusion: Minimally invasive renal

    Full Text Available Background: Most of male infertility are caused by defect in sperm motility (asthenozoospermia. The molecular mechanism of low sperm motility in asthenozoospermic patients has not been fully understood. Sperm motility is strongly related to the axoneme structure which is composed of microtubules and supported by outer dense fiber (ODF and fibrous sheath (FS protein. The objective of this study was to characterize the ODF (ODF1 and ODF2 expression in asthenozoospermic infertile male and control normozoospermic fertile male.Methods: Asthenozoospermic samples (n=18 were collected from infertile patients at Andrology Lab, Cipto Mangunkusumo Hospital Jakarta and control were taken from normozoospermic fertile donor (n=18. After motility analyses by computer-assisted sperm analysis (CASA, semen were divided into two parts, for Western blot and for immunocytochemistry analysis. Antibody against ODF1 and ODF2 protein were used in both analyses.Results: Analysis of ODF1 protein expression showed bands with molecular weight of ~30 kDa and ODF2 ~85 kDa. The mean band intensity of ODF1 and ODF2 protein were lower in the asthenozoospermic group (AG compared to normozoospermic group (NG. Moreover, both ODF proteins were less intense and less localized in the AG than NG. Sperm motility was lower in AG, compared to control NG, i.e. average path velocity (VAP = 32.07 ± 7.03 vs 37.58 ± 8.73 µm/s, p = 0.455; straight line velocity (VSL = 24.17 ± 6.90 vs 27.61 ± 4.50 µm/s, p = 0.317 and curvilinear velocity (VCL = 45.68 ± 7.91 vs 55.55 ± 16.40 µm/s, p = 0.099.Conclusion: There is down-regulation of ODF1 and ODF2 protein expression and less-compact localization in AG sperm compared to the NG. These changes might have caused disturbances in the sperm motility as observed in this study.

    Young males have testicular germ cells tumors (TGCT) as the most common malignancy and its incidence is increasing in several countries. Besides unilateral orchiectomy (UO), the treatment of TGCT may include surveillance, radiotherapy, or chemotherapy (CT), basing on tumor histology and stage of disease. It is well known that both radio and CT may have negative effects on testicular function, affecting spermatogenesis, and sex hormones. Many reports investigated these aspects in patients treated with bleomycin, etoposide, and cisplatin (BEP), after UO. In contrast no data are available on the side effects of carboplatin treatment in these patients. We included in this study 212 consecutive subjects who undergone to sperm banking at our Andrology and Human Reproduction Unit after UO for TGCT. Hundred subjects were further treated with one or more BEP cycles (BEP-group), 54 with carboplatin (CARB group), and 58 were just surveilled (S-group). All patients were evaluated for seminal parameters, sperm aneuploidy, sperm DNA, sex hormones, volume of the residual testis at baseline (T0) and after 12 (T1) and 24 months (T2) from UO or end of CT. Seminal parameters, sperm aneuploidies, DNA status, gonadic hormones, and testicular volume at baseline were not different between groups. At T1, we observed a significant reduction of sperm concentration and sperm count in the BEP group versus baseline and versus both Carb and S-group. A significant increase of sperm aneuploidies was present at T1 in the BEP group. Similarly, the same group at 1 had altered sperm DNA integrity and fragmentation compared with baseline, S-group and Carb group. These alterations were persistent after 2 years from the end of BEP treatment. Despite a slight improvement at T2, the BEP group had still higher percentages of sperm aneuploidies than other groups. No impairment of sperm aneuploidies and DNA status were observed in the Carb group both after 1 and 2 years from the end of treatment. Despite

    Background Erectile dysfunction (ED) is a common impairment among older men, and the prevalence rates increase sharply after age of 60 years. Most studies have focused on the prevalence rate or dangerouse factors. The aim of this study was to investigate the basic epidemiologic data about ED patients with different ED courses. The purpose of this researth was to understand the therapeutic effect of phosphodiesterase type 5 inhibitor (PDE5-1) and see how and why the ED course impact the progress of ED and the therapeutic effect of PDE5-1 treatment.Methods From June 2008 to June 2009, 4252 questionnaires (Quality of Erection Questionnaire, QEQ) were gathered from 46 centers by urology or andrology doctors all around China. Patients with ED (age > 20 years) filled in first half of the questionnaires when they came for the first time, and then completed the second half 4 weeks after PDE5-1 therapy.Results ED courses of most patients were less than 5 years (<5 years, 74.0%; 5-10 years 20.8%; >10 years, 5.2%). As ED course increasing, the incidence of the risk factors of ED, such as smoking, drinking, hypertension, diabetes, heart disease and hyperlipidemia also increase (P ≤0.01). PDE5-1 was effective in improving the quality of sexual activities (P ≤0.01). Administration of PDE5-1 improves satisfaction, enjoyment and frequency of sexual activities. The longer the ED course, the worse the therapeutic effect (<5 years, 96.1%; 5-10 years, 94.9%; >10 years, 89.0%) (P<0.01).Conclusions The ED course greatly affected the therapeutic effect of PDE5-1, the patients with ED should consult doctor at early stage of the disease. Admistration of PDE5-1 effectively improves the penile erection and the quality of sexual life of the patients hence should be considered as first-line medicine in the treatment of ED.

    Full Text Available Estudaram-se o efeito do tempo de avaliação da libido sobre a conduta sexual de touros e a atividade de monta em diferentes proporções touro:vaca e verificaram-se as possíveis correlações entre libido, circunferência escrotal e qualidade seminal. Vinte touros foram selecionados por meio de exame andrológico e teste da libido e distribuídos segundo as proporções touro:vaca: T1= 1:25; T2= 1:50; T3= 1:75; e T4= 1:100, com cinco repetições em cada proporção. O aumento no tempo de avaliação do teste da libido de 10 para 15 minutos reduziu o percentual de touros classificados como questionáveis e com libido boa e elevou o percentual de touros com libido muito boa e excelente. O tempo de 10 minutos interferiu negativamente no desempenho sexual dos touros. Das 1250 vacas utilizadas nos quatro tratamentos, 738 (59,0% foram marcadas, sendo 624 (84,5%, 112 (15,2% e duas (0,3% marcadas por um, dois e três touros, respectivamente. As correlações entre libido e qualidade seminal e circunferência escrotal foram baixas.The effect of time evaluation of bull libido on sexual behavior and the bull breeding activity for different bull:cow proportions were studied. Correlations between libido and scrotal circumference and sperm quality were estimated. Twenty selected bulls based on andrologic evaluation and on libido test were randomly allotted to four treatments in the following bull:cow proportions: T1= 1:25; T2= 1:50; T3= 1:75; and T4= 1:100. The increase in the time of the libido test from 10 to 15min reduced the percentage of bulls classified as questionable and good libido, and increased the percentage of bulls with very good and excellent libido. Ten minutes of libido test negatively affected sexual activity of the bulls.

    勃起功能障碍(ED)与高血压之间的关系是男科学研究的重点领域.目前研究认为,这两种疾病拥有相似的病理生理过程,如氧化应激效应造成血管内皮损害以及RhoA/Rho激酶活性上调.两种疾病均为血管功能损害这一病理过程的不同阶段.定期细致而全面评估高血压合并ED患者病情,并予以合理药物治疗显得尤为重要.在高血压患者中,5型磷酸二酯酶抑制剂无论是单用还是联合抗高血压药物使用都取得了令人满意的效果.目前,基因治疗以及脂肪源性干细胞治疗都展现出了良好的前景,通过转化医学方法可使其更好的为临床服务.%The relationship between erectile dysfunction (ED) and hypertension is a focus in andrological research. ED and hypertension share some pathophysiologic pathways, such as oxidative stress-induced endothelial dysfunction and up-regulated RhoA/Rho kinase activity, and both are the diseases at different stages of the pathological process of vascular dysfunction. Thus, it is particularly important to conduct regular and meticulous evaluation of such patients, so as to give rational individualized medication. Phosphodiesterase-5 inhibitors have an excellent efficacy and safety profile in the management of hypertension, either used alone or with antihypertensive medication. At present, gene therapy and adipose-derived stem cell therapy have displayed favorable prospects in the management of ED and hypertension, and translational medicine may help bring more clinical benefits.

First we investigated the folate receptors (FRs, folate's pathway into cells, and its expression in normal and cancerous cells, before detailing the mechanism of action of vintafolide, its clinical applications, and the results of different study phases.Materials and methods: A literature search was conducted through Pubmed/Medline, Google, ClinicalTrials.gov and websites of pharmaceutical companies. Only articles in English were selected. All articles investigating folate receptor expression in ovarian cancer were selected first, than articles reviewing platinum resistance. Papers about vintafolide were collected, while those talking about synthesis and biochemistry concerns were excluded. The different Phase I and II studies were read, and an update on the website of pharmaceuticals companies were added.Results: FR is a bundle-membrane receptor that is expressed normally in some normal tissues on the apical surface of cells, but highly expressed in ovarian cancer cells (>80%. It collects folate through endocytosis. Chemotherapy does not modify its expression in ovarian cancer cells, and its expression appears to be mostly associated with a poor prognosis and platinum resistance. Vintafolide is a folate-desacetylvinblastine monohydrazide conjugate, allowing a liberation of the drug into the cytoplasm of cancerous cells via the FR-α (FR α and endocytosis, with high specificity. Phase I studies showed a 2.5 mg bolus dose to be nontoxic, with moderately adverse events. Phase II clinical trials for the first time demonstrated a statistically significant improvement in disease

    The aim of this study was to evaluate the possible association between cardiometabolic risk factors accumulation and vitamin D status in a cohort of Italian normal weight and overweight male children. 108 boys enrolled in an andrological health prevention project underwent physical examination, anthropometric measurements, and fasting blood sampling. Serum blood glucose, HDL-cholesterol, triglycerides, parathyroid hormone, and 25-hydroxyvitamin D (25(OH)D) were measured. Cardiovascular risk factors were defined according to the National Cholesterol Education Program Adult Treatment Panel III modified for age. Lean and overweight subjects differed in terms of waist circumference (P < 0.001), HDL-cholesterol (P = 0.001), triglycerides (P = 0.001), systolic blood pressure (P < 0.001) and diastolic blood pressure (P = 0.002). Both groups had similar mean 25(OH)D levels (P = 0.160) and were below the sufficiency threshold: indeed only 24 % of normal weight had 25(OH)D ≥30 ng/ml, and even less in the overweight/obese group (8 %, P = 0.03 vs. normal weight). A significant accumulation of risk factors in course of 25(OH)D insufficiency was detected in both the whole cohort and in the normal weight group (P = 0.003 and P = 0.04, respectively) with odd ratios of 1.31 (1.16-1.49 95%CI) and 1.41 (1.18-1.69 95%CI), respectively. In course of vitamin D deficiency, the odd ratios were 2.24 (1.34-3.77 95%CI, P = 0.003) in the whole cohort and 2.40 (1.27-4.82 95%CI, P = 0.03) in lean subjects. We reported a considerable occurrence of cardiovascular risk factors in course of hypovitaminosis D in overweight/obese boys and even in lean subjects, which normally would not have been further evaluated by considering the sole BMI-related parameters. In this regard, 25(OH)D levels appear as a potential discriminating parameter able to identify male children at higher health risk. PMID:26323345

    Multiplex polymerase chain reaction (PCR) has been widely used to detect Y-chromosome microdeletions,which is one of the major causes of male infertility.Both the European Academy of Andrology (EAA) and the European Molecular Genetics Quality Network (EMQN) have recommended the use of sY84 and sY86 markers for the detection of azoospermia factor a (AZFa) microdeletion during DNA testing for male infertility.In this study,a large-scale analysis of AZF microdeletion in a total of 630 Chinese males,including healthy semen donors (n=200),infertile males with normal sperm count (n=226) and patients with either nonobstructive azoospermia or severe oligozoospermia (n=204),was performed.A series of nine sequence-tagged site (STS) markers from the AZF region of the Y chromosome was used to detect microdeletions.All primers were designed based on the recommendations of the National Center for Biotechnology Information.An unusually high incidence (73/630,11.6%) of sY84-absent but sY86-present genotypes was observed in the AZFa microdeletion screening.Sequencing the sY84-flanking region revealed a total of 73 patients with sY84-absent but sY86-present genotypes have a T-to-G transversion at the fifth base from the 5' end of the reverse sY84 primer.These prevalent false positives,which were not only observed in infertile men,but also observed in donors,resulted from a single-nucleotide polymorphism (SNP) named rs72609647 in the targeting sequence of the reverse sY84 primer.Our study suggests that a pre-screening of existence of rs72609647 polymorphism can prevent the frequent false positive results of AZFa microdeletions detection in the infertile Chinese males.Given the SNP rs72609647 was recently found in a deep sequencing of a Chinese individual,the current EAA and EMQN standards may need to be scrutinized among different populations to avoid the potential genetic variations in the primer binding sequences.

    Digito‑rectal examination(DRE) of the prostate provides useful information on the state of prostate growth and on the presence of suspected peripheral nodules. The aim of this study is to describe the clinical and biochemical correlates of ifnding an enlarged prostate size at DRE in subjects with sexual dysfunction(SD). Aconsecutive series of 2379patients was retrospectively studied. The analysis was focused on a subset of subjects(n=1823; mean age 54.7±11.4) selected for being free from overt prostatic diseases. Several parameters were investigated. After adjusting for confounders, the presence of an enlarged prostate size at DRE was associated with a higher risk of metabolic syndrome(HR=1.346(1.129–1.759);P=0.030), type2 diabetes mellitus(HR=1.489(1.120–1.980);P=0.006), increased LDL cholesterol(>100mgdl−1; HR=1.354(1.018–1.801);P=0.037) and increased mean blood pressure(BP) values(HR=1.017(1.007–1.027) for each mmHg increment;P=0.001). Accordingly, enlarged prostate size was also associated with a higher risk of arteriogenic erectile dysfunction(ED), as well as with other andrological conditions, such as varicocele and premature ejaculation(PE). PSA levels were signiifcantly higher in subjects with enlarged prostate size when compared to the rest of the sample(HR=3.318(2.304; 4.799) for each log unit increment in PSA levels;P<0.0001). Arteriogenic ED, according to different criteria, was also associated with increased PSA levels. In conclusion, our data support the need to examine prostate size either by clinical(DRE) or biochemical(PSA) inspection in subjects with SD, in order to have insights into the nature of the SD and the metabolic and cardiovascular(CV) background of the patient.

    Introduction and objective: In Europe, nearly every sixth couple in the reproductive age is involuntarily childless. In about 30%, both male and female reveal fertility problems. In about 10% of infertile men, azoospermia is the underlying cause. As conventional therapeutic options are limited, surgical testicular sperm extraction (TESE) is necessary to obtain sperms for assisted reproductive techniques. Regarding the females, up to 30% of all idiopathic infertilities are due to alterations of the uterine tube So far, no imaging technique, which does not require any labelling, is available to evaluate the male and female genital tract at a microscopic level under in vivo conditions. Thus, the aim of this study was to investigate the potential of optical coherence tomography (OCT) as a non-invasive diagnostic tool in gynaecology and andrology. Material and Methods: Tissues samples from the bovine testis, epididymis, vas deferens, ovary, oviduct (ampulla and isthmus) and uterus were obtained immediately after slaughter (14 cows aged 3 to 8 years and 14 bulls aged 3 to 6 years; breeds: Holstein- Friesian, and Deutsches Fleckvieh). Imaging was done by using the US Food and Drug Administration (FDA) approved probe-based Niris Imaging System (Imalux, Cleveland, Ohio, USA) and the Telesto 1325 nm OCT System and Ganymede 930 nm OCT System (Thorlabs Inc., Dachau, Germany). All images obtained were compared to histological images after paraffin embedding and HE staining. Results: OCT imaging visualized the microarchitecture of the testis, epididymis, spermatic duct and the ovary, oviduct and uterus. Using the Thorlabs systems a axial resolution of approx. 5μm and lateral resolution of 8- 15μm could be achieved. Different optical tissue volumes could be visualized, which depends on the optical penetration depth of the wavelength of the system used. While the tissue volume observed by probe based Imalux-OCT is similar to the used Thorlabs systems, the optical resolution is

    syndromes, usages and dosages of Sargassum and Radix Glycyrrhizae. RESULTS 1 137 pieces of literature were all retrieved, in which 60 pieces occupying the total number of 5.28% were the literature with Sargassum-Radix Glycyrrhizae antagonistic combination. Modified Haizao Yuhu Decoction was used for various diseases like gynecology, andrology, dermatology instead of simplified limited treatment on goiter. Qi-stagnation and phlegm-coagulation pattern was the primary syndrome pattern among indications. The clinical application of Haizao Yuhu Decoction was frequently combined with phlegm-removing drugs, drugs for promoting blood circulation to remove blood stasis, qi-regulating drugs, heat-clearing drugs and tonic drugs. The proportion of Sargassum and Radix Glycyrrhizae between 2: 1 and 5: 1 was more common in the compatibility application of clinical doctors, taking up 74.60% of the total number of literature, and there were no reports about adverse reactions. CONCLUSION Haizao Yuhu Decoction with antagonistic compatibility has a wider range in clinical application. Among its indications, the primary syndrome pattern is still qi-stagnation and phlegm-coagulation pattern and is in accordance with the application of original prescription. The compatibility proportion of sargassum and Radix Glycyrrhizae conspicuously differs from the original prescription.
