Effect of estrogens on boar sperm capacitation in vitro
BACKGROUND Mammalian sperm must undergo a series of controlled molecular processes in the female reproductive tract called capacitation before they are capable of penetrating and fertilizing the egg. Capacitation, as a complex biological process, is influenced by many molecular factors, among which steroidal hormone estrogens play their role. Estrogens, present in a high concentration in the fe...
متن کاملEffect of heparin on in vitro capacitation of boar sperm.
Chlortetracycline (CTC) fluorescent pattern, the ability to undergo acrosome reaction (AR) upon exposure to 10 microM calcium ionophore A23187 and vitality estimation were used to investigate the effect of the sulfated glycosaminoglycan heparin on the in vitro capacitation of porcine spermatozoa. Sperm incubation in capacitating medium (CM) supplemented with 10 mM heparin for up to 120 min, sho...
متن کاملBiochemical and immunochemical characterization of boar sperm flagellar protein with role in hyperactivation/capacitation process.
Investigations on specific and functionally active sperm antigens could bring about the elucidation of the mechanisms of gamete interaction and help the search for new approaches in prognosis and regulation of fertility. Previously, we reported that the monoclonal antibody (Mab) 3G4 against capacitated boar spermatozoa was capable of inhibiting boar sperm-porcine zona pellucida binding due to i...
متن کاملThe CatSper channel modulates boar sperm motility during capacitation.
The cation channel of sperm (CatSper) comprises four transmembrane subunits specifically expressed in human, equine, murine and ovine spermatozoa, apparently implicated in capacitation, hyperactivation and acrosome exocytosis. Western blotting and immunocytochemistry showed hereby that CatSper subunits are also present in boar spermatozoa, primarily over the sperm neck, tail and cytoplasmic dro...
متن کاملSperm Capacitation and in Vitro Fertilization in Cattle
The slaughtered cows or heifers have a large number of immature oocytes within primordial follicles or developing follicles. Therefore, it is useful to aspirate immature oocytes, which would be wasted if left unprocessed, from ovaries; subsequently they are matured in vitro (IVM), fertilized in vitro (IVF), and cultured in vitro (IVC). Also most recently it has been shown that immature oocytes ...
