The present study was undertaken to assess the correlation between and relative predictive value of each of the following variables and progestin-induced withdrawal bleeding: cervical mucus appearance, serum E2 level, patient age, duration of amenorrhea, smoking and exercise habits, and body composition. Of 120 oligomenorrheic and amenorrheic women evaluated, only cervical mucus appearance and serum E2 level were significantly associated with response to progestin challenge. A multivariate logistical regression analysis showed cervical mucus to be the most predictive variable followed by serum E2 level. No absolute E2 level was found to discriminate between those who did and those who did not have withdrawal bleeding after progestin challenge. These data suggest that office examination of cervical mucus may be a useful indicator and guideline in planning therapy.
