Abstract
Summary
In this study we have demonstrated that acute adrenalectomy (1000 hr proestrus) has no effect on the release of LH on proestrous afternoon. However, chronic adrenalectomy results in the loss of some factor responsible for synchronizing the preovulatory LH surge. Since this investigator has shown previously (15) that progesterone can influence the timing of LH release in ovariectomized and ovariectomized-adrenalectomized animals, it is most likely that adrenal progesterone is involved in synchronizing this event.
