Effect of heparin on in vitro capacitation of boar sperm
(Sociedad de Biología de Chile, 2006)
Energy Metabolism and Hyperactivation of Spermatozoa from Three Mouse Species under Capacitating Conditions
(MDPI, 2022-01-10)
Mammalian sperm differ widely in sperm morphology, and several explanations have been presented to account for this diversity. Less is known about variation in sperm physiology and cellular processes that can give sperm ...
Regulation mechanisms and implications of sperm membrane hyperpolarization
(Elsevier Science, 2018-12)
Mammalian sperm are unable to fertilize the egg immediately after ejaculation. In order to gain fertilization competence, they need to undergo a series of biochemical and physiological modifications inside the female ...
Bicarbonate is required for migration of sperm epididymal protein DE/CRISP-1 to the equatorial segment and expression of rat sperm fusion ability
(Society for the Study of Reproduction, 2004-05)
Numerous studies have demonstrated that sperm capacitation is a bicarbonate-dependent process. In the rat, capacitation has not been studied as much as in other species, mainly because of the difficulties in carrying out ...
Pharmacological inactivation of catsper blocks sperm fertilizing ability independently of the capacitation status of the cells: implications for non-hormonal contraception
(Frontiers Media S.A., 2021-07)
Cation channel of sperm (CatSper), the main sperm-specific Ca2+ channel, plays a key role in mammalian fertilization, and it is essential for male fertility, becoming an attractive target for contraception. Based on this, ...
Acrosin release and acrosin activity during incubation in capacitating media using fresh and frozen-thawed dog sperm
(Sociedad de Biología de Chile, 2011)
Sperm phospholipid methyltransferase activity during preparation for exocytosis
(1994)
The present report describes experiments to evaluate phospholipid methyltransferase activity in golden hamster spermatozoa incubated under different conditions. Washed cauda epididymal sperm were incubated with taurine, ...
Timing of sperm capacitation appears to be programmed according to egg availability in the female genital tract
(Elsevier Science Inc, 2004-07)
The time course of the level of A23187-induced acrosome reaction between human and rabbit spermatozoa was compared. It was extended in the former (a periodic ovulator) and short in the latter (an induced ovulator). This ...
