Danazol as a luteolytic agent.

A C Wentz, K C Sapp

    Fertility and Sterility
    |January 1, 1978
    PubMed
    Summary

    Danazol did not shorten menstrual cycles in healthy women. While it reduced progesterone, it did not demonstrate a luteolytic effect, making it unlikely as a contraceptive.

    Area of Science:

    • Endocrinology
    • Reproductive Medicine
    • Pharmacology

    Background:

    • Danazol, a synthetic derivative of 17 alpha-ethinyltestosterone, is being investigated for potential contraceptive properties.
    • Understanding danazol's effect on the luteal phase is crucial for evaluating its efficacy.

    Purpose of the Study:

    • To determine if danazol exhibits a luteolytic effect in healthy nonpregnant volunteers.
    • To assess danazol's impact on menstrual cycle length, luteal phase duration, and steroidogenesis.

    Main Methods:

    • Administration of danazol to healthy nonpregnant volunteers.
    • Monitoring of cycle length, duration of the luteal rise, and luteal steroidogenesis.
    • Administration of human chorionic gonadotropin during danazol treatment to assess progesterone response.

    Main Results:

    • Danazol decreased the duration of the luteal rise and progesterone output in most subjects.
    • No significant decrease in total menstrual cycle length was observed.
    • Human chorionic gonadotropin administration during danazol treatment successfully increased progesterone output.

    Conclusions:

    • Danazol's observed effects suggest it is unlikely to be effective as a luteolytic contraceptive agent.
    • Further research may be needed to explore alternative contraceptive mechanisms or dosages.
