    Area of Science:

    • Endocrinology
    • Pharmacology
    • Reproductive Medicine

    Background:

    • The precise mechanisms of action for danazol remain unclear.
    • The impact of danazol on normal human endocrine values is a subject of ongoing debate.

    Purpose of the Study:

    • To investigate the endocrine and endometrial effects of danazol therapy.
    • To determine dose-dependent and duration-dependent alterations in hormone levels.

    Main Methods:

    • Twenty patients received danazol at doses ranging from 200-800 mg daily.
    • Blood serum samples were collected for hormonal analysis.
    • Endometrial biopsies and basal body temperatures were monitored serially.

    Main Results:

    • Danazol did not significantly alter luteinizing hormone-follicle-stimulating hormone (LH-FSH) basal levels, prolactin, TSH, TBG, thyroxine, cortisol, or androstenedione.

  • Estrone and estradiol serum levels showed modest, non-dose-dependent decreases.
  • Significant dose-related increases in serum testosterone and dehydroepiandrosterone sulfate (DHEA-S) were observed.
  • Endometrial atrophy was noted across all tested danazol dose levels.

    • Conclusions:

    • Danazol therapy induces significant hormonal changes, including increased androgens and decreased estrogens.
    • The observed endometrial atrophy suggests a potent effect on the uterine lining.
    • Further research is warranted to elucidate danazol's complete mechanism of action and clinical implications.
