Infertility caused by antispermatozoal antibodies in the male experience from an intermittent high dose cortisone regimen.

Seventeen infertile male patients with antispermatozoal antibodies in seminal plasma and/or serum were treated with methylprednisolone, 48-96 mg daily for one week every other month in synchrony with the partner's menstrual cycles. Three to six treatment courses were given. One patient with draw from further treatment because of mental disturbance during the first cycle. Seminal plasma titres were affected more than titres in serum by the treatment. In the 16 couples completing treatment at least one pregnancy was achieved in six. Children were born to five of them. The observed pregnancy rate is similar to that previously reported. Risks of the treatment and safety precautions are discussed.
