  • Publication number: 20150164484
    Abstract: Disclosed are methods for assessing the period of potential fertility, days of maximum fertility, and transition to the infertile phase via measurement and processing of vaginal CA125 (MUC16) levels. In one embodiment, the fertile and infertile phases of the ovulatory normal female menstrual cycle are defined by a pattern or signature of day-specific vaginal CA125 levels. Suitably, signatures are based upon daily cotton swab collection of vaginal epithelial and fluid plus subsequent assay of CA125. Day-specific vaginal CA125 assay levels increase during the period of potential fertility and reach a maximum with inflection point generally before and near the time of ovulation. Derived functions of day-specific vaginal CA125 are used to predict fertility, enhance conception, and for birth control.
