To study whether sperm migration into and through the oviduct follows an invariable pattern or is subject to regulation, rats in pro-oestrus, oestrus, metoestrus or dioestrus were inseminated in the upper third of each uterine horn with 106-206 epididymidal spermatozoa. The ampullary and isthmic...

Aflatoxin B1 was fed to experimental rats and pigs at the rate of 1.5, 4 and 20 p.p.m. for 4, 16, and 4 wk resp., or was given as single doses of the LD50 and half the LD50. Fed at the rate of 1.5 and 4 p.p.m., aflatoxin produced disorders of the oestrous cycle in rats followed by cessation of the...

Abstract

Preovulatory follicles were isolated from groups of 4 or 5 rats at various times during pro-oestrus. Progestin level was lowest (1.12 plus or minus 0.62 ng/follicle) at 08.00 h and highest (16.16 plus or minus 5.09 ng/follicle) at 18.00 h. It was concluded that preovulatory progesterone peaks in...

THE data were obtained from 215 ♀ albinos of Wistar extraction. Vaginal introitus occurred from 459 hrs. before to 72 after the onset of heat as determined by the response to manual manipulation; in the majority of animals it occurred between 48 hrs. before and 12 hrs. after. The av. age of onset...
