Effect of natural estrogen on the serum level of follicle-stimulating hormone (FSH), estradiol and estrone in post-menopausal women and its effect on endometrium.

Serum FSH, estradiol and estrone levels were assayed in 35 post-menopausal women who received the three commonly available estrogen preparations Premarin, Progynova and Harmogen. The results were compared with the levels during treatment with Dixarit. Hormone levels did not change when Dixarit was used. The levels of estrone and estradiol increased significantly (p less than 0.01) when estrogen preparations were used. There was no abnormality in the endometrium at the end of the treatment period.
