The endocrine disruptor bisphenol A (BPA) is well known for its adverse effect on male fertility. Growing evidence suggests that BPA may interact with testicular germ cells and cause infertility as a result of its estrogenic activity. Objective of current in vitro study was to investigate the proliferation, survivability and stemness properties of mouse testicular germ cells exposed to BPA, and to evaluate possible expression of cellular proteome. Our results showed that germ cell viability and proliferation were not affected by low concentrations (0...

REVIEW
Robert M Coward, Jesse N Mills
A variety of surgical options exists for sperm retrieval in the setting of obstructive azoospermia (OA). With appropriate preparation, the majority of these techniques can safely be performed in the office with local anesthesia and with or without monitored anesthesia care (MAC). The available techniques include percutaneous options such as percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA), as well as open techniques that include testicular sperm extraction (TESE) and microsurgical epididymal sperm aspiration (MESA)...

Because rhesus macaques (Macaca mulatta) are prolific breeders, overpopulation can be problematic in both research and feral populations. Currently, the most effective contraceptive methods are hormonal control in female macaques and vasectomies in males. These methods each come with innate challenges, the foremost being the alteration of necessary hormonal patterns. In this study, we assessed the use of zinc gluconate neutralized with arginine as a novel, nonsurgical alternative to male contraception in 12 rhesus macaques...

Infertility, whether of male or female origin, is a critical challenge facing the low birth rate and aging population throughout the world, and semen analysis is a cornerstone of the diagnostic evaluation of the male contribution to infertility. This means that tools which can characterize sperm properties in an effective manner are very much needed. The conventional approaches are essentially image-based, which have a limited value for analyzing sperm properties. Here, we show that an assay using nanomechanical sensors can detect sperm motility based on nanomotion...

REVIEW

Clinical varicoceles have been associated with impaired semen parameters and male-factor infertility. Varicocele repair can improve live birth rates for men with clinical varicocele. Varicocelectomy is often combined with assisted reproductive techniques (ART) such as intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI). Here we review the literature examining varicocelectomy before ART to evaluate whether improved pregnancy outcomes are realized. Although insufficient evidence exists to determine if correcting a varicocele improves IUI outcomes, a clinical benefit is observed when correcting a clinical varicocele in oligospermic and nonobstructed azoospermic men before IVF/ICSI...

DiGeorge syndrome (DGS) is one of the most frequently seen chromosomal abnormalities. The major genetic cause of DGS is a microdeletion on chromosome 22q11.2. Majority of the cases are diagnosed during their childhood. DGS is rarely considered and diagnosed in adulthood. Herein, we report the first case of a patient with DGS and azoospermia in the literature. Our patient was a 35-year-old male with mild dysmorphic features, hypernasal voice, mental retardation, and azoospermia. His laboratory tests and echocardiographic assessments were normal...

The most common cause of male infertility is idiopathic oligo-, and or astheno-, and /or teratozoospermia. In such cases, anti-estrogens, antioxidants (vitamins and trace elements) or carnitines are used, but the evidence on their effectiveness is inconsistent; there are currently no published studies exploring their concurrent use. AIM: To investigate the efficacy and safety of the L- and acetyl-L-carnitine complex, vitamins A, E, C, selenium, zinc and other antioxidants ("SpermActin" + "More than vitamins") in combination with clomiphene citrate (CC) in managing male idiopathic infertility in the form of oligo, and/or astheno-, and/or teratozoospermia...

PURPOSE: The aim of this study is to evaluate whether the MTHFR contribution to male decreased fertility can be attributable to anomalies in sperm nucleus DNA structure in relation to defective methylation. METHODS: The presence of MTHFR C677T, contributing at most for male infertility, was determined from a venous blood sample, using real-time polymerase chain reaction (PCR). Sperm DNA fragmentation (SDF) and sperm nucleus decondensation index (SDI) measurements were performed using acridine orange and flow cytometry...

Harold C Wiesenfeld, Lisa E Manhart
Health consequences of sexually transmitted diseases disproportionately affect women, making it important to determine whether newly emerged pathogens cause sequelae. Although the pathogenic role of Mycoplasma genitalium in male urethritis is clear, fewer studies have been conducted among women to determine its pathogenic role in the female reproductive tract. Pelvic inflammatory disease (PID) is an important cause of infertility and ectopic pregnancy, and Chlamydia trachomatis and Neisseria gonorrhoeae are recognized microbial causes...

Several studies have addressed the impact of viral infections on male infertility. However, it is still unknown whether human papillomavirus (HPV) can alter seminal parameters. The aim of this study was to determine the prevalence of HPV in the semen of male partners of couples seeking fertility evaluation. Additionally, we assessed the possibility that HPV infections affect seminal parameters. A total of 229 semen samples were collected from men in the Sperm Analysis Section of São Camilo Laboratory of Maringá, Brazil, between October 2015 and March 2016...

Urethral coitus is a rare type of sexual practice, usually due to vaginal agenesis or hymeneal anomalies. We report a case of urethral coitus in a healthy couple who were evaluated for infertility. The female partner had cribriform hymen and dilated urethral orifice but did not report any problems except infertility and her genital anatomy was normal. The male partner reported concerns over his penile size but was otherwise healthy. After incision of hymen, they were able to have vaginal coitus and successfully conceived...

Although in vitro and in vivo laboratory studies have demonstrated androgen and anti-androgen effects on male reproduction from phthalate exposures, human studies still remain inconsistent. Therefore, a case-control study (n = 289) was conducted to evaluate the associations between phthalate exposures, male infertility risks, and changes in metabolomic biomarkers. Regional participants consisted of fertile (n = 150) and infertile (n = 139) males were recruited from Nanjing Medical University' affiliated hospitals...
