3,20-Dioxopregn-4-en-17-beta-yl acetate, also known as 17-Hydroxyprogesterone acetate, is a new steroid
for oral administration. It has a progestational activity
which is at least twice that of anhydrohydroxyprogesterone[1].
3,20-Dioxopregn-4-en-17-beta-yl acetate could induces secretory changes in the endometrium and luteal changes in the exfoliated vaginal epithelial cells, reduces fern-like patterns of the cervical mucus, causes a rise of basal body temperature, and induces withdrawal bleeding in castrates[1].
