Similarly, you may ask, how long is sperm capacitation?
Sperm transport through the female genital tract can occur quite rapidly (times as short as 15–30 min have been reported in humans), whereas capacitation may take from 3 h to 24 h . It is speculated; therefore, that capacitation is not completed until after the spermatozoa have entered the cumulus oophorus.
Furthermore, what is capacitation reaction? Capacitation is an activation process that involves both enhancement of flagellar activity and the biochemical and structural changes in the plasma membrane of the sperm head that prepares sperm to undergo the acrosomal reaction.
Furthermore, what does capacitation mean?
Medical Definition of capacitation : the change undergone by sperm in the female reproductive tract that enables them to penetrate and fertilize an egg.
What happens during sperm capacitation?
Capacitation is a functional maturation of the spermatozoon. The changes take place via the sperm cell membrane in which it may be that receptors are made available through the removal of a glycoprotein layer. The area of the acrosomal cap is also so altered thereby that the acrosome reaction becomes possible.
