background: sodium arsenite can impair male reproductive function by inducing oxidative stress. silymarin is known as a potent antioxidant.objective: this study was performed to investigate if silymarin can prevent the adverse effect of sodium arsenite on ram sperm viability, motility and mitochondrial membrane potential.materials and methods: epidydimal spermatozoa obtained from ram were divid...

Ram seminal plasma increases the fertility of frozen-thawed ram spermatozoa deposited into the cervix. The aim of the current study was to compare the effect of ram seminal plasma to that of bull seminal plasma, dog prostatic fluid, protein-free TALP TrilEq (Triladyl with 0.5 mt of Equex STM paste added to each 100 mt) and heat-treated skim milk on longevity and percentages of progressively mot...

During transit through the epididymis, spermatozoa are normally kept immotile and do not attain the ability to become motile until they reach the caudal epididymis. This study was undertaken to determine whether endocannabinoids play a role in the epididymis and in particular in suppressing the ability of spermatozoa to become motile. We show that the levels of the endocannabinoid 2-arachidonoy...

The relationship between the three basic parameters of ejaculated spermatozoa, i.e. concentration, motility and morphology, and the results of intracytoplasmic sperm injection (ICSI) were investigated in 838 microinjection cycles. A further 123 ICSI treatment cycles in which testicular spermatozoa were used for microinjection were also evaluated. The influence of anti-sperm antibodies (ASA) on ...

The aim. aim of the work was to study indicators spermatogenesis in lake frog, Pelophylax ridibundus (Pallas, 1771), zone influence emissions from Burshtyn Thermal Power Plant (TPP).
 Materials and methods. Urinal sperm testes samples were taken male frogs under conditions anthropogenic pollution (Burshtyn industrial area). Such parameters as concentration ejaculate, number live spermatozo...

BACKGROUND The incidence of overweight and obesity in men of reproductive ages is rising, which may affect fertility. Therefore, this study aims to assess the associations between BMI, central adiposity and sperm parameters in men of subfertile couples. METHODS Ejaculate volume (ml), sperm concentration (millions per ml), percentage of progressive motile and immotile spermatozoa and total mot...

Klinefelter's syndrome is one of the known causes of azoospermia or cryptoazoospermia, and it may present in non-mosaic (47,XXY) or mosaic (47,XXY/46,XY) form. The likelihood of finding spermatozoa in the ejaculate or testicular tissue of patients with mosaic Klinefelter's syndrome is low, and with the non-mosaic form, even lower. We describe a patient with non-mosaic Klinefelter in whom initia...

The microinjection of completely immotile spermatozoa may impair the outcome of intracytoplasmic sperm injection (ICSI). Eleven couples underwent an initial ICSI cycle with 100% immotile freshly ejaculated spermatozoa. Two-pronuclear fertilization ensued in 18 of 145 (12.4%) successfully injected oocytes. None of these cycles resulted in a pregnancy. Nine couples underwent ICSI in subsequent cy...

Objective: The aim of this study was to evaluate the effects of aging on semen quality in a population of infertile couples. Methods: A cross-sectional study of semen samples obtained from 1,500 men randomly selected from couples who attended an infertility clinic was conducted. The analyses were performed using Spearman’s correlation and Mann-Whitney tests. The age groups consisted of men ≤ 35...
