Cyclic AMP in the rat ovary: effect of endogenous LH secretion.
Cyclic AMP levels increased in ovaries from normal cycling rats on the afternoon of proestrus at the same time as the plasma LH peak occurred. Plasma progesterone was also elevated at this time. These results complement the extensive in vitro data indicating that cyclic AMP mediates the action of LH on the ovary.
