Epididymis cholesterol homeostasis and sperm fertilizing ability.
Cholesterol, being the starting point of steroid hormone synthesis, is a long known modulator of both female and male reproductive physiology especially at the level of the gonads and the impact cholesterol has on gametogenesis. Less is known about the effects cholesterol homeostasis may have on postgonadic reproductive functions. Lately, several data have been reported showing how imbalanced c...
متن کاملAn epididymis-specific beta-defensin is important for the initiation of sperm maturation.
Although the role of the epididymis, a male accessory sex organ, in sperm maturation has been established for nearly four decades, the maturation process itself has not been linked to a specific molecule of epididymal origin. Here we show that Bin1b, a rat epididymis-specific beta-defensin with antimicrobial activity, can bind to the sperm head in different regions of the epididymis with varied...
متن کاملEvaluation of frozen thawed cauda epididymal sperms and in vitro fertilizing potential of bovine sperm collected from the cauda epididymal
In the present study, the fertilizing potential of semen recovered from slaughtered bulls epididymis was evaluated after cryopreservation, by conventional techniques and flow cytometry methods. The cauda epididymal was dissected and sperm were recovered and evaluated for volume, sperm concentration, and membrane and acrosome integrity using a flow cytometer. Sperm fertility potential was tested...
متن کاملMotility and fertilizing ability of frozen-thawed raM sperM froM two sheep breeds
The aim of the study was to evaluate motility parameters of Lacaune (Lc) and east-Friesian (eF) ram frozen-thawed spermatozoa by cASA (computer-Automated Sperm Analysis) technique in relation to their in vivo fertilizing ability. Fresh ejaculates were diluted in a Triladyl extender containing 20 % egg yolk, 6 % glycerol and 0.1 % trehalose and frozen in a liquid nitrogen vapour. The evaluation ...
متن کاملThe ethane dimethanesulfonate-induced decrease in the fertilizing ability of cauda epididymal sperm is independent of the testis.
Several decades ago it was reported that when adult male rats were exposed to a single injection of 50 mg/kg body weight ethane dimethanesulfonate (EDS) and mated with untreated females, average litter size was significantly reduced as early as 2 weeks later. Recently, we demonstrated that EDS exerts multiple effects in the epididymis of adult rats. Some of these effects were independent of red...
