Biological, microscopic and scanning electron microscopic investigations of the effects of postinor /d-norgestrel/ in rabbits.

The contraceptive effect of d-norgestrel given immediately after copulation in various quantities was investigated in rabbits. It was established that the effect is dose-dependent. A correlation was found between the amount of dose administered and the changes taking place on the surface of endometrium. It can be suggested that d-norgestrel alters the surface of the endometrium to such an extent that nidation is unable to take place; therefore, it can be used for postcoital contraception at any time.[1]
