The effect of Danazol on the pituitary function, thyroid function, and mastodynia
Danazol effectively treated mastodynia, decreased estradiol and triiodothyronine levels, and reduced TRH-stimulated prolactin, while not significantly altering LH, FSH, or TSH.

This study evaluated Danazol (Winobanin) in 24 patients with mastodynia, with 10 undergoing GnRH and TRH testing before and during treatment to assess pituitary functional reserve, alongside measurements of estradiol, T3, T4, LH, FSH, prolactin, and TSH. Danazol relieved symptoms in 17/24 patients versus 21% with placebo, while basal and GnRH-stimulated LH and FSH levels were not significantly altered. Estradiol decreased significantly, TRH-stimulated prolactin responses were significantly reduced with unchanged basal prolactin, and T3 levels fell significantly while T4 and TSH were unchanged; the authors conclude Danazol may mask hypothyroidism by lowering T3. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.
