Dienogest is a synthetic steroid that has been used as a progestogen in contraceptive pills and is currently being studied for its possible clinical use in the treatment of endometriosis. In this study, we investigated the direct effects of…

Leuprorelin (leuprolide, D-Leu6-(des-Gly10-NH2)-LH-RH ethylamide) acetate is a super-active agonist of luteinizing hormone-releasing hormone (LH-RH). We developed once-a-month injectable microcapsules of this agonist by our novel in-water d…

Estrogen biosynthesis (aromatase activity) was investigated in human adenomyosis tissue and compared with that of the normal myometrium, endometrium, and endometrial cancer tissues. Homogenates were incubated with [1,2,6,7-3H]androstenedion…

To understand the mechanism of biological action of gestrinone (R2323), which has a therapeutic effect against endometriosis, the binding of gestrinone to numerous classes of intracellular steroid binding proteins was studied in the human u…

Abstract The serum prolactin (PRL) levels of 34 cases of endometriosis, 26 cases of adeno‐m‐osis, 30 cases of functional d‐smenorrhea, and 9 patients with m‐oma uteri were measured b‐ radioimmunoassa‐. The incidence of h‐perprolactinemia (>…

Abstract Nine patients with pelvic endometriosis were treated with gestrinone in a dose of 2.5 mg twice weekl‐ for 6 to 7 months. All patients became anovulator‐ with sporadic episodes of painless uterine bleeding lasting various periods of…

This study was designed to clarify the effects of danazol on levels of serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin, progesterone (P), and 17 beta-estradiol and endometrial steroid receptors (for estrogen [E…

Steroid receptors in endometriosis and adenomyosis were investigated to clarify their clinical significance. The receptor levels were determined by Scatchard plot analysis (4 degrees C, by dextran-coated charcoal). In the cytosols of both t…
