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.

Twenty-two infertile women with repeated deficient results in the postcoital test received clomiphene citrate or tamoxifen. The patterns of luteinizing hormone, follicle-stimulating hormone, prolactin, 17 beta-estradiol (E2), and progesterone were examined during the follicular and periovulatory phases of the menstrual cycle, as were the cervical mucus characteristics. Under clomiphene treatment, an overproduction of E2 was observed (P less than 0.01), which did not result in an improvement of the cervical mucus characteristics. The pH of the endocervical mucus was lower (P less than 0.01). Under tamoxifen treatment, the serum E2 levels were higher (P less than 0.05) and normalized. Higher spermatozoa penetration meter scores were observed during the preovulatory and periovulatory periods, whereas the pH of the endocervical mucus was not lowered. These data support that tamoxifen may be preferential to clomiphene in treating this kind of infertile woman.

In this study we have evaluated the score, sperm migration and ultrastructural characteristics of cervical mucus present in amenorrhoeic women under exclusive breastfeeding at 30, 60, 90, 120, 150 and 180 days post-partum. Periovulatory mucus samples from seven normally cycling women were used as a control. The average scores of post-partum and periovulatory mucus were 4.6 +/- 0.4 and 14.1 +/- 0.5 respectively. Twenty-one (39%) of the 54 post-partum cervical mucus samples and all (100%) periovulatory mucus samples allowed sperm migration. Positive sperm migration into post-partum mucus was observed at all time intervals studied. The only parameter that correlated with sperm migration into post-partum mucus was ferning formation. Sperm migration was obtained in all post-partum mucus samples with a score greater than 8, but samples with scores between 2 and 7 also showed sperm penetration. Scanning electron microscopic studies showed the characteristic spongy appearance of periovulatory mucus. Post-partum mucus was formed by a dense mesh (rocky appearance), when samples were generally unable to sustain sperm migration, but samples where sperm migration occurred showed small areas of spongy mucus mixed with areas in which a dense mesh and high cellularity was observed.

Two types of cervical mucus are recognized, oestrogenic and gestagenic. These are constituted by different subtypes, and their characteristics change depending on variations in the hormonal levels and on the existence of several pathologies. Our aim was to identify the ultrastructure and crystallization characteristics of the cervical mucus in women suffering from polycystic ovary syndrome, and to compare these characteristics with those of normal control women. Cervical mucus samples were taken from 10 women, 4 control group women (with normal ovulatory menstrual cycles) and 6 suffering from polycystic ovary syndrome (2 with ovulatory and 4 with anovulatory cycles). This mucus was characterized according to its ultrastructure and crystallization. The type of mucus obtained was related to the levels of oestradiol and progesterone present when the samples were taken. As regards mucus ultrastructure, differences were found between the control women and those with polycystic ovary syndrome and anovulatory menstrual cycles. Such variations were evident in the type of mesh and the average diameter of the mucus pores. Mucus crystallization in control women showed the usual oestrogenic disposition: fern-like (L, P2), rectilinear (S) or a hexagonal structure (P6). On the other hand, in women with polycystic ovary syndrome, indefinite mucus crystallizations were found, as well as crystallization patches resembling oestrogenic and gestagenic-like mucus. This study shows that the ultrastructure and crystallization characteristics of the cervical mucus in polycystic ovary syndrome women are different from those of control women. The latter would be dependent on their levels of oestradiol and progesterone.
