Conception Control by a Single Monthly Injection

Abstract
Seventy-mree patients, during 929 menstrual cycles, were given a single injection of 1 ml of a new long-acting progestin-estrogen combination containing 150 mg. of dihydroxy-progesterone acetophenide and 10 mg. of estradiol enanthate (Deladroxate) as a contraceptive. It induced consecutive monthly cycles of desquamation averaging 25.8 days in length with a range of 4-9 days. The treatment was well tolerated, with a minimum of side effects. No pregnancies resulted: Among the clinic patients selected there was a surprisingly good acceptance of this method of contraception.
