PURPOSE: A recent study suggested that ibuprofen may alter testicular physiology in a state of compensated hypogonadism, but only evaluated spermatogenic cells in a laboratory ex-vivo model with no significant effect, and found no significant change in follicle stimulating hormone (FSH) in men treated with ibuprofen. The study did not evaluate the impact of ibuprofen use on clinical semen parameters, which has not been assessed to date. The purpose of this study was to evaluate the impact of ibuprofen on semen parameters...

Little is known of the genetic variability in semen quality traits in cattle and their inter-relationships. The objective of the present study was to estimate genetic parameters for a range of semen quality measures. The data consisted of 35,573 ejaculates from 787 artificial insemination bulls of 16 breeds. Genetic parameters were estimated using a repeatability animal linear mixed model. Large breed differences were detected with Belgian Blue bulls, on average, producing lesser semen volume than all other breeds while the Charolais bulls, on average, produced semen with fewer live sperm and reduced motility...

STUDY QUESTION: When is the investigation and treatment of midline prostatic cysts (MPC) of clinical value in the work-up of males of infertile couples? SUMMARY ANSWER: With a prevalence of 10.2% in infertile men, MPC should be investigated according to a seminal algorithm detecting a MPC volume >0.117 ml, which may impair semen parameters, and could be treated to improve sperm count and achieve natural pregnancy. WHAT IS KNOWN ALREADY: MPC are frequent and are considered a correctable cause of male infertility...

Bisphenol A (BPA) is a high-production volume industrial chemical found in many consumer products. BPA is a suspected potent endocrine disruptor, with endocrine-disrupting properties demonstrated in animal studies. Few human studies have examined bisphenol A exposure in relation to male fertility and, results are divergent. The aim of the study is to examine the associations between urinary BPA concentration and male fertility. Bisphenol A urinary concentrations were measured using gas chromatography coupled with tandem mass spectrometry in 315 men under 45 years of age with normal sperm concentration (⩾15 mln/ml) recruited from a male reproductive health clinic...

The aim of the study was to investigate the associations between standard semen parameters and the parameters reflecting oxidative stress intensity, antioxidant defense functions, levels of selected macro and trace elements, and parameters characterizing immune system function. The study group consisted of 103 fertile males. Based on semen volume, sperm concentration, total sperm count, and percentage of motile sperm at 1 hour postcollection, the individuals were divided into two equal groups-those with excellent (EX) semen quality and those with mediocre (ME) semen quality...

Accurate semen evaluation is necessary to maintain high reproductive efficiency but difficult to accomplish. The objective was to determine if the ability to bind oviduct cells or oviduct glycans are useful supplements to traditional semen analyses. Measuring binding to specific soluble glycans is less laborious than assessing binding to oviduct cell aggregates and more suitable for routine use. Previous work has shown that sperm binding to oviduct cells improves fertility prediction, possibly by estimating the ability of sperm to form an oviduct reservoir...

BACKGROUND: Sperm capacitation is essential for proper fertilization and is associated with increased sperm hyperactivity (HA) and acrosome reaction (AR). For successful fertilization, AR timing is critical; accordingly, early spontaneous AR may not facilitate fertilization. Paraoxonase 1 (PON1) possesses antioxidant properties which affect sperm capacitation. The association between PON1, semen parameters, and capacitation is not fully understood. OBJECTIVE: To study PON1 activity in relation to human sperm hyperactivity and AR...
