The mechanism by which cells in the ampullae of the rat oviducts undergo rapid deciliation during each estrous cycle and the effects of estrogen on the ciliated cells were examined. Untreated rats were killed on each day of the 5-day estrous cycle, a

Rats with regular 5-day estrous cycles were sacrificed on different days of the cycle and the ampullae of their oviducts were excised, fixed in glutaraldehyde, stained with uranyl acetate and lead citrate, and examined using electron microscopy. Sinc

Time-release pellets of levonorgestrel (LNG), the progestogenic hormone contained in the contraceptive system Norplant, were implanted subdermally in mice, after the animals had mated and ovulated but before uterine implantation of embryos would have

This study utilized a mouse model to examine whether levonorgestrel implants, such as Norplant, may exert their contraceptive effects in part by adversely affecting oocyte quality. Time-release pellets and silastic capsules containing levonorgestrel

Phosphoenolpyruvic acid and pyruvic acid are among the few compounds that two-cell mouse embryos have been found capable of using as energy sources; most of the compounds in the glycolytic pathway and Krebs cycle that have been tested have been found

Testosterone propionate, cortisone, or sesame oil vehicle were given to rats during the last week of pregnancy so that effects of the hormones on anogenital distance, breeding capacity and vaginal opening of the female progeny could be contrasted. Te

Experiments tested the hypothesis that one role of protein in embryo culture media is protection of embryos against potentially embryotoxic substances in the media. Mouse embryos were cultured in modified Krebs-Ringer bicarbonate medium and in modifi

Blood sera obtained from patients in an in vitro fertilization and embryo transfer program at the time of oocyte retrieval were tested for their capacities to support embryo development by using them as supplements for media in which mouse embryos we

Rats were given a multivitamin diet supplement during pregnancy and lactation that moderately exceeded recommended dietary allowances of the vitamins. The vitamin regimen had no significant effect on length of the gestation period, number of pups fou

A total of 54 human fetal cord sera, 42 lots of Ham's F-10 medium, and 36 lots of plastics were tested during a 10-month period with a mouse in vivo fertilization system. Two-cell embryos were collected from the oviducts of superovulated and mated (C
