Effect of a new oral antiandrogen-estrogen combination on the endometrium: histological and ultrastructural scanning
Acta Europaea Fertilitatis
|January 1, 1986
Abstract:
Endometrial biopsies were obtained in 12 volunteers between 18 and 35 years old who had used SHB 209 AE oral contraceptive during the previous six months. Three main types of endometrial patterns were observed: proliferative, very similar to a normal proliferative phase; early secretory: similar to early postovulatory endometrium; late secretory: characterized by diffuse predecidual changes in the stroma. At SEM after one week a great prevalence of nonciliated cells was observed. During the 2nd and the 3rd week, the endometrial surface appears still flattened with scanty glandular outlets.
