Gynecologic Disorders

Genital Tract Infections

Menstrual disorders and alteration in the mucus pattern can also be caused by gynecologic disorders such as anatomical abnormalities, neoplasia or inflammatory diseases.

The second most frequent cause of fertility disorders are inflammatory processes, usually secondary to genital tract infections (GTI), which predominantly have an origin in sexually transmitted diseases. Microbial mucin degrading enzymes are associated with sexually transmitted infections and produced by the offending micro organisms. These enzymes will alter the mutually beneficial cohabitation that normally exists between commensals such as Lactobacillus, which use glycogen as an energy source and contribute to normal mucin turnover by the production of mucin degrading enzymes such as sialidase. Mucin molecules would be partly or completely degraded by the microbial enzymes. These molecules dictate the rheological properties which determine the amount and viscosity of the mucus, so these properties will change in response to enzymes produced by microbial organisms in the genital tract (37).

A woman who knows her own mucus pattern in times of health will be able to early recognize a GTI. These will usually cause a continuous discharge whose characteristics will depend upon the etiologic agent causing the infection. In general, an ovulatory pattern is identifiable, but it is associated with a creamy, sticky BIP. Symptomatic infections (itching and a characteristic discharge) are usually caused by fungi, bacteria or parasites. Chlamydia trachomatis infections, with an incidence of 13% in infertile couples and often associated with tubal pathology, (30, 34) will be asymptomatic or present with continuous moistness and variable degrees of pelvic pain. This infection may also show a mucopurulent discharge associated with the mucus discharge. The recognition of this infection and timely treatment may prevent fertility disorders.

It has been shown that these infections provoke pelvic inflammatory processes and are associated with spontaneous abortions. Recent studies (20) have shown that the mesh spacing between mucin fibers is large enough for small viruses as human papiloma virus (HPV), associated to cervical neoplasia, to diffuse unhindered through mucus. Bacterial vaginosis related bacteria, micoplasms, trichomonas vaginalis, and gardnerella among others, must also be considered when unusual mucus patterns or menstrual irregularities occur. In this situation, both members of the couple should be treated in order to restore the healthy condition.

Contraceptive Pill

Fertility disorders may also be iatrogenic, caused by contraceptive pills or by hormonal therapy. Women coming off the pill may present cycles with short luteal phases, absence of a well defined mucus pattern, indicating anovulation, (21) poor mucus response due to damaged cervical epithelium and a poor menstrual flow due to alterations of the endometrial lining. Major cycle disturbances lasting for up to seven cycles (cycle length > 35 days or luteal phase of < 10 days, monophasic basal body temperature or anovulatory cycles) occur frequently in women, after discontinuation of the birth control pills. It has also been shown that in comparison with formerly used mechanical anti-conception methods; pill users have lower monthly percentages of conception during the first three months and a somewhat lower percentage between the fourth and tenth months after discontinuation of the pill (13, 14, and 16).

Conclusion

Self knowledge acquired by learning the BOM is an invaluable tool for women willing to achieve a healthy reproductive system state. Thus, identification of medical and environmental causes of abnormal menstrual cycle patterns may provide clues to the causes of the most frequent fertility disorders. Early diagnosis of these alterations, as can be achieved through self fertility awareness, will not only improve fertility disorders, but may help in the diagnosis and treatment of other pathologies such as metabolic conditions, endocrine disorders, anatomical alterations, pelvic inflammatory diseases or even neoplasia. Moreover, the menstrual cycle pattern should be taken into consideration in the clinical decision-making process.
