[Sterility from hormonal causes and unexplained sterility. Treatment with cyclofenil. Double-blind controlled study]

Abstract

We treated 213 women during 3 cycles by cyclofenil versus placebo in a double-blind study. These women had infertility caused by ovulatory deficiencies, a cervical factor or idiopathic infertility. Twenty-six of the 114 women receiving cyclofenil became pregnant and 21 of the 99 receiving the placebo. The cumulative pregnancy rates were identical in the 2 groups: 22 per cent in 3 cycles. The authors insist on the importance of a good doctor-patient relationship and the role of the placebo effect in any treatment of infertility.
