Endocrinology, 1979
LHRH, via inducing inordinately high LH levels, can disrupt pregnancy in the rat. Based on studies indicating that LH can reduce gonadal content of its own receptor and thereby modify LH-dependent steroidogenesis, the effect of contragestational LHRH treatment on ovarian LH receptor dynamics was investigated.

Contraception, 1999
The effectiveness of postcoital contraception can only be estimated. The most commonly used method of calculation compares the expected pregnancy rate in the exposed population to the resultant pregnancies after treatment. Estimation of the fertile period and the day of ovulation are critical to calculate the expected pregnancies. The aim of this study

[Postcoital contraception with steroid hormones].
Zentralblatt fur Gynakologie, 1984Large doses of estrogens employed for postcoital contraception have definitely been shown to be effective, but estrogens used in such high doses would result in a high incidence of side-effects. Therefore this method should be reserved for the occasional emergency. Postcoital estrogen-progestogen-combination is suitable for women exposed to an isolated
