Efficacy of human menopausal gonadotropins as therapy for abnormal cervical mucus.

ABSTRACT

Traditional therapies for abnormal cervical mucus, other than timed intrauterine insemination, are noteworthy for being ineffectual. Patients (n = 27) with documented abnormal Insler scores in repetitive cycles and failure to conceive with traditional treatments were screened with conjugated equine estrogens (CEE) for estrogen responsiveness of the cervix. Only 5 patients were found unresponsive. Seventeen patients with CEE-responsive cervices then were treated with human gonadotropins (hMG), initially 1 ampule days 5 to 11. If the mucus failed to improve, the hMG was increased to standard doses. Eight patients responded to 1 ampule hMG with improved mucus and conception. The remainder required 2 ampules hMG. In patient cycles with corrected cervical mucus, the viable fecundibility (fv) was 0.35. This is significantly higher than predicted for this population (fv = 0.09; P less than 0.01). In all, 14 of 17 patients conceived viable pregnancies during hMG treatment. It is concluded that graduated hMG is efficacious in treating patients with abnormal cervical mucus responsive to CEE. It is preferable to either in vitro fertilization or gamete intrafallopian transfer, based on both cost and efficacy for most patients.
