objective: the main objective of the current study was to observe the ameliorative effect of withania somnifera on arsenic-induced testicular toxicity by exploring the crucial parameters such as sperm counts, sperm motility, hormonal assay and lipid peroxidation including histopathology. materials and methods: in the present study, arsenic in the form of sodium arsenite was administered orally ...

In this study, we conducted a simultaneous analysis of sperm count and viability in rats by flow cytometry (FCM). Epididymal fluids were taken from the caudal epididymis of 12 to 13 week-old Sprague-Dawley rats. The fluids were weighed and mixed with Dulbecco's phosphate buffered saline (D-PBS). Propidium iodide, which can stain only dead sperm, was used to distinguish viable and dead sperm. Th...

Semen from 5210 sperm bank donors was analyzed and trends in semen quality were evaluated at Shandong Human Sperm Bank between 2008 and 2014. After 2-7 days of abstinence, semen samples were collected. Measurements of semen volume, sperm concentration, sperm forward motility, and total sperm count were performed. There were significant declining trends in semen volume, sperm concentration, sper...

Semen from 10 932 male partners of infertile couples was analysed and sperm parameter trends were evaluated at the Reproduction Biology Laboratory of the University Hospital of Marseille (France) between 1988 and 2007. After 3-6 days of abstinence, semen samples were collected. Measurements of seminal fluid volume, pH, sperm concentration, total sperm count, motility and detailed morphology of ...

BACKGROUND This is the first study to assess the outcome of sperm washing and intrauterine insemination (IUI) cycles in human immunodeficiency virus-positive (HIV(+)) men to determine any predictors of success, as well as evaluating the effect of HIV on sperm parameters. METHODS Semen characteristics were evaluated in 106 HIV(+) men and a control group of 234 HIV(-) men, and the effect of mar...

Effect of a combination of pesticides, viz. Delatmethrin 1% + Chlorpyriphos 35% EC, has been studied on the reproductive toxicology of wistar rats. Male rats were exposed to test substance at the dose level of 15, 25, and 35-mg/kg body weight for a consecutive period of 20 weeks. At the end of the experimental period, all the animals were subjected for necropsy, sperm parameters such as motilit...

Eight male dogs with both asthenozoospermia and teratozoospermia were used in this study. In experiment 1, semen was collected 10 times at intervals of 48 hr, 24 hr and 12 hr in 4 of the 8 dogs, and the semen quality was evaluated. In experiment 2, semen was collected 5 times at 24-hr intervals in the other 4 dogs. The spermatozoa collected on day 1 and day 5 were incubated for 4-6 hr in Canine...
