background: besides the well-known adverse effects of valproate (vpa), disorders related to male reproductive functions have been reported. furthermore, only a limited number of previous studies have reported the relationship between vpa dose and impairment of the hormonal axis and semen quality. a patient with reversible changes that occurred in the sperm parameters after a dose increment of v...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. Conventional semen analysis is the routine test performed during the evaluation of a couple’s fertility status. The test is cost-effective and easy to perform and at the same time provides essential information on quantitative semen parameters such as semen volume, sperm motility, concentration, viability and morpholo...

BACKGROUND Sperm selection method is usually used to collect these cells for in vitro-assisted reproduction. Few studies reported the relationship of in vivo fertility and semen parameters after sperm selection; hence, the present study attempted to assess different semen parameters after post-thaw or sperm selection, using density gradient separation BoviPure®, to predict in vivo fertility. ...

BACKGROUND Organophosphates are broad class of chemicals widely used as pesticides throughout the world. We performed a cross-sectional study of associations between dialkylphosphate metabolites of organophosphates and semen quality among pesticide applicators in Majes (Arequipa), Peru. METHODS Thirty-one men exposed to organophosphate (OP) pesticides and 31 non-exposed were recruited (age, 2...

black bengal goat is the heritage and one of the potential genetic resources of bangladesh. genetic and phenotypic parameters for semen characteristics and their relationships with scrotal circumference in black bengal bucks were estimated in this experiment. genetic parameters were estimated by residual maximum likelihood procedure, fitting an animal model ignoring maternal genetic or permanen...

Semen cryopreservation is widely used in assisted reproductive technologies, but it reduces sperm quality dramatically. The aim of this study was to develop a model using basal semen quality to predict the outcome of postthaw semen parameters and improve the efficiency of cryopreservation in a human sperm bank. Basal semen parameters of 180 samples were evaluated in the first stage, and a multi...

Motility is one of the most important characteristics associated with the fertilising ability of spermatozoa indicating their viability and structural integrity. Therefore, the examination of motility constitutes an integral part of semen analysis. Computer-assisted semen analysis (CASA) allows an accurate and objective assessment of different sperm motion characteristics with high repeatabilit...

OBJECTIVES To assess the technical feasibility and compare the semen quality in men with or without pregnancy after percutaneous embolization of varicoceles in the management of infertility. METHODS The records of 102 patients who underwent retrograde varicocele embolization between January 1997 and January 2002 were reviewed through the Hospital Information Support System. Infertility was th...

With expanding knowledge on the health benefits of exercise, there is an increasing demand for information on the andrological consequences of participating in sports. These consequences are especially important in the context of infertility problems worldwide. The so-called "male factor" is reported in up to 50% of couples having trouble with conception. The answer to the question, "Is physica...

Contrary to public opinion on the causes of infertility, male factor accounts for over 50% of infertility during reproductive age of couples and even there are several reports on its increase during the recent years. Semen analysis as one of the main laboratory tests provides valuable information about male fertility status. In spite of huge development in diagnostic tests and laboratory innova...
