Abstract
Competitive progesterone antagonists, including two novel steroids, viz., 11β,19-[4-(cyanophenyl)-o-phenylene]-17β-hydroxy-17α-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one and 11β,19-[4-(3-pyridinyl)-o-phenylene]-17β-hydroxy-17α-(3-hydroxyprop-1(Z)-enyl)-4-androsten-3-one, inhibit formation of endometrial glands at below their ovulation inhibiting dose and the abortive dose, and thus achieve oral contraception in females without adversely affecting the menstrual cycle and without risk of aborting a previous implanted fertilized egg or a fetus.
