Sperm penetration through cervical mucus in infertile couples in relation to selected cervical factors.

One-hundred-and-fourteen women of infertile marriages with negative post-coital test (PCT) results were studied. The women were divided into three groups: those with anatomical anomalies of the cervix, abnormalities of the cervical mucus and a negative PCT and normal parameters in cervical mucus. Patients were treated with mestranol when the physicochemical characteristics of the cervical mucus were impaired. Those with antispermatozoal antibodies found by means of the Katsh test were treated with desensitizing therapy, condoms and homologous artificial insemination (AIH). Among all the patients therapy resulted in 23 pregnancies. After applying these treatments to women, 49 of them (43%) had positive PCT results.
