Ovarian serotonin content in relation to ovulation

Abstract
In the mature cyclic female rat, analysis for ovarian serotonin content reveals comparatively high serotonin content. Fluctuation of serotonin content was observed; peak for serotonin was observed at estrus. In gonadotropintreated immature rats, there was no detected ovarian serotonin using this procedure. It was concluded that ovaries from gonadotropin-treated immature rats are physiologically different from ovaries taken from mature cyclic rats.
