Ovulation, fertilization, and early embryonic development in the menstruating fruit bat, Carollia perspicillata.

To characterize periovulatory events, reproductive tracts were collected at 12 hr intervals from captive-bred, short-tailed fruit bats, Carollia perspicillata, on days 1-3 post coitum and examined histologically. Most bats bred readily. Graafian follicles developed large antra and exhibited preovulatory expansion of the cumulus oophorus.

Selectivity in the transport of spermatozoa to oviductal reservoirs in the menstruating fruit bat, Carollia perspicillata.

To better document the timing of ovulation and fertilization, female reproductive tracts were collected every 12 h from captive-bred fruit bats (Carollia perspicillata) on days 1-3 postcoitum and examined histologically. This also permitted observations on sperm transport, storage, and disposition. As the animals had previously been sexually segregated, most had been cycling and possessed menstrual uteri at the time of collection.
