Capacitation of Rabbit Spermatozoa: Species Specificity and Organ Specificity.

Abstract

It has been found that washed rabbit sperm may be capacitated in the uterus of an estrous rabbit, rat, and dog, indicating that the capacitation mechanism is similar in these species. It was shown that washed rabbit sperm are capacitated only in the uterus and oviduct of the estrous rabbit and not in the bladder, colon, and knee joint, indicating that the factors necessary for capacitation are limited to the female reproductive tract.
