Relation between the Secretion of FSH during the Periovulatory Period and Ovulation during the Next Cycle

A dose-dependent reduction in the secretion of FSH during estrus in the hamster was induced by the injection of increasing volumes of bovine follicular fluid (bFF). Partial inhibition of the release of FSH during estrus was observed after 120 µl of bFF was administered to hamsters at 3 h intervals beginning at 1800 h during proestrus and continuing until 0900 h during estrus. Four days later, significantly fewer ova were ovulated by these animals (P
