Techniques such as mass spectrometry have led to unprecedented knowledge of the proteins that are present in the spermatozoa of humans and other mammals. However, in spite of their high-throughput and fractioning techniques, most of the techniques in use only offer average values for the entire sperm population. Yet, ejaculate is very heterogeneous, and average values may mask relevant biological information.The application of flow cytometry may overcome this disadvantage, allowing proteomic analysis at the single-cell level...

OBJECTIVES: To characterize the current gender and subspecialty of those holding academic departmental administrative and educational leadership roles in urology. METHODS: We conducted a cross-sectional observational study of U.S. Urology Residency Programs in 2016 to 2017. Inclusion criteria were participation in the Urology Residency Match Program and having a department of urology website. From June 1, 2016 to August 20, 2016, each department's website was queried...

OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex disease, the etiology of which is not well understood. Alterations in potential candidate genes involved in the biosynthesis and metabolism of androgens, folliculogenesis, and insulin and glucose metabolism have been suggested as possible etiologies. Dipeptidyl peptidase-4 (DPP4) plays a key role in glucose homeostasis and, thus, in the regulation of insulin secretion. The aim of our study was to analyze the DPP4 activity and concentrations in the serum of PCOS and non-PCOS patients and, additionally, study the activation of the DPP4 promoter by androgens in vitro...

STUDY QUESTION: Can a consensus and evidence-driven set of terms and definitions be generated to be used globally in order to ensure consistency when reporting on infertility issues and fertility care interventions, as well as to harmonize communication among the medical and scientific communities, policy-makers, and lay public including individuals and couples experiencing fertility problems? SUMMARY ANSWER: A set of 283 consensus-based and evidence-driven terminologies used in infertility and fertility care has been generated through an inclusive consensus-based process with multiple stakeholders...

INTRODUCTION: Male genital lichen sclerosus (MGLSc) is an acquired, chronic, inflammatory skin disease that is associated with significant morbidity and squamous cell carcinoma of the penis (PSCC). However, some clinical, diagnostic and management controversies endure, including the relationship with penile intraepithelial neoplasia (PeIN). OBJECTIVES: To clarify clinical presentations, diagnostic approaches, histological findings, response to treatment and the relationship with PeIN...

Seminal oxidative stress (OS) is well-known to affect male fertility status. The discrepancy in OS measurement has hindered its clinical use as a quality indicator for semen. Some tests measured single markers of oxidants or reductants, leading to lack of standardization of results. Oxidation-reduction potential (ORP) is a better representative for OS as it provides an overall measure of the activity of both oxidants and reductants. ORP assessment by MiOXSYS has been introduced as a measure of OS with high specificity in differentiating fertile from infertile semen samples...

OBJECTIVE: Previous study conducted by the Turkish Society of Andrology in 1999 reported the prevalence of erectile dysfunction (ED) as 69.2% in men of ≥40 years of age, using a single-item non-validated question. This rate seemed to be higher compared to the studies reported worldwide. So, there was a need to carry out another epidemiological study by using validated questionnaires. Our aim was to investigate ED prevalence, severity, and its correlates in men aged ≥40 years using validated tools...

OBJECTIVES: To assess the prevalence of OSA in men presenting with ED at a single centre. SUBJECTS AND METHODS: All men attending a specialised andrology outpatient department with a new diagnosis of erectile dysfunction were included in this prospective study. All patients completed 3 questionnaires: International Index of Erectile Function (IIEF) and 2 sleep questionnaires. The sleep questionnaires used were the 'OSA screening' questionnaire and the Insomnia severity index'...

The integrity of sperm deoxyribose nucleic acid (DNA) is one of the determinants that ensure normal fertilization, implantation, pregnancy, and the generation of a healthy progeny. Assessment of sperm DNA fragmentation has gained importance as a tool to provide significant information regarding sperm quality, and it can independently predict sperm fertilizing potential. The sperm chromatin dispersion (SCD) assay is one of the available techniques to detect sperm DNA damage with results comparable to the gold standard - Sperm Chromatin Structure Assay...

Uncertainty of measurement has become a paramount factor to consider in pathology. In the UK, consideration of uncertainty of measurement is mandatory for medical laboratories who apply to be accredited against ISO15189:2012 via the United Kingdom Accreditation Service. This guideline intends to help those working within diagnostic andrology to better understand the concept of uncertainty, and how it can be applied to semen analysis and post-vasectomy semen analysis. The various areas where uncertainty may exist are identified, and guidance is provided to minimise this uncertainty...

PURPOSE: The aim of the present study is to assess impairment of spermatogenesis induced by varicocele in, to our knowledge, the largest single-centre caseload available to date. MATERIALS AND METHODS: We conducted a retrospective study on 4230 consecutive patients attending our Department for andrological outpatient assessment and preconception check-ups between 2011 and 2014. A total of 2113 patients had varicocele (Group V), while the remaining 2117 were selected as the control group (Group C)...

OBJECTIVE: To explore the potential relationship between erectile dysfunction (ED), low testosterone levels, and the Charlson Comorbidity Index (CCI). MATERIAL AND METHODS: Cross-sectional study on patients referred to the andrology unit in 7 Spanish centers. The ED was diagnosed and graded using the International Index of Erectile Function (IIEF-5) score. Total testosterone, the prevalence of each comorbidity, and the CCI were compared between patients with different grades of ED...

BACKGROUND: The aim of this study was to investigate seminal oxidant-antioxidant activity in idiopathic and varicocele infertility in men. METHODS: Total anti-oxidant capacity (TAC), total oxidant status (TOS), paraoxonase (PON1), aryl esterase (ARE), and total thiol levels (TTL) were measured in seminal plasma with an autoanalyzer. The TOS/TAC ratio was determined as the oxidative stress index (OSI). A histopathological evaluation of the sperm was performed in the andrology laboratory of the hospital...

BACKGROUND/AIM: Concerns about the detrimental effects of occupational and environmental exposure on male reproductive function have been raised by reports of declining sperm quality over the last decades. The aim of this study was to investigate the association between altered semen parameters and exposure to occupational risk factors as assessed by questionnaire. MATERIALS AND METHODS: We conducted a cross-sectional questionnaire-based study among a population of 2122 men who underwent andrological investigation for couple infertility...

OBJECTIVE: This study investigated the effects of D-ribose and L-cysteine on aluminum-induced testicular damage in male Sprague-Dawley rats. METHOD: A total number of thirty-five (35) adult male Sprague-Dawley rats were divided into four groups (AD). Group A (comprised five (5) rats) was designated the Control Group that received Physiological Saline; while groups B, C, and D (comprised ten (10) rats) were given 75 mg/kg, 150 mg/kg and 300 mg/kg of body weight of aluminum chloride respectively for 39 days...
