   Capacitation
   A process that occurs as sperm pass through the female genital tract which gives them the ability to penetrate and fertilize the ovum. (This can be mimicked in culture medium ) see fertilization.

   capacitation
   A process occurring in mammalian sperm after exposure to secretions in the female genital tract. Surface changes take place probably involved with the acrosome which are necessary before the sperm can fertilize an egg.

   Capacitation
   `Capacitation` is the final step in the maturation of mammalian spermatozoa and is required to render them competent to fertilize an oocyte. This step is a biochemical event; the sperm move normally and look mature prior to capacitation. `In vivo` this final step typically occurs after ejaculation, in the female reproductive tract. `In vitro`, capacitation can occur in sperm that have either undergone ejaculation or have been extracted from the e...

   capacitation
   (kә-pas″ĭ-ta´shәn) the process by which the glycoprotein coat and the seminal proteins are removed from the surface of the sperm's acrosome by substances secreted by the uterus or fallopian tubes of the female genital tract, thereby permitting the acrosome reaction to occur.

   capacitation
   Capacitation is a process whereby the glycoprotein coat is modified and seminal proteins are removed from the surface of the sperm. There are no morphologic changes. Capacitation occurs in in vitro fertilization; after capacitation, the acrosomal reaction can occur. [L. capacitas, fr. capax, capable of]

8. 
   Capacitation
   A change in sperm that occurs as they travel through the female reproductive tract that enables the sperm to penetrate and fertilize an egg. Sperm that have not have been capacitated in the female reproductive tract cannot fertilize the egg.
