[Effect of natural exogenous estrogens on the response to LH-RH (author's transl)]

LH-RH in doses of 25 and 50 microgram,, was injected intravenously into normal women pre-treated or not with conjugated natural estrogen. An inhibition of the release of LH in response to 25 as well as 50 microgram of LH-RH, was observed in women receiving either dose of estrogens (0.628 and 1.25 mg).
