Our previous findings demonstrate that some oviductal secretion proteins bind to gametes and affect sperm physiology and gamete interaction. One of these proteins possesses an estimated molecular weight of 14 kDa. The objective of this study was to i

Innovative methods to select sperm subpopulations with the best fertilizing ability are needed in assisted reproductive techniques (ART) in order to improve fertilization and pregnancy rates, while also considering possible epigenetic effects on the

Ulispristal acetate (UPA) is a selective progesterone receptor modulator widely used for emergency contraception (EC). The described main mechanism of action is by inhibiting or delaying ovulation; however, the postovulatory effects of the drug are s

Oviductal secretion and gamete interaction

Autor: Carlos Zumoffen, Estefanía Massa, Sergio Ghersevich

Publikováno v: Reproduction (Cambridge, England). 149(1)

Experimental evidence from the last 30 years supports the fact that the oviduct is involved in the modulation of the reproductive process in eutherian mammals. Oviductal secretion contains molecules that contribute to regulation of gamete function, g

Proteins from human oviductal tissue-conditioned medium modulate sperm capacitation

Publikováno v: Human reproduction (Oxford, England). 25(6)

Background Spermatozoa acquire the ability to fertilize an oocyte when they become capacitated. Capacitation takes place when sperm pass through the female reproductive tract, interacting with female fluids. Both tyrosine phosphorylation of sperm pro
