Study of Transdermal Testosterone Patches in Surgically Menopausal Women With Low Libido

Women with hypoactive sexual desire disorder (HSDD) who had undergone bilateral salpingo-oophorectomy and hysterectomy were randomized into a 24-week, multicenter, multinational, double-blind (DB), parallel-group, placebo-controlled study. Patients were stratified based on their use of oral or transdermal ET and randomized to receive placebo or testosterone transdermal system. Patients had to maintain a stable dose of estrogen throughout the study. Patients who completed the first 24 weeks of the study were given the opportunity to participate in a 3.5 year open-label (active treatment) study extension which was added to the protocol by amendment. Safety was assessed by adverse events, lipids, serum chemistry with hepatic, renal and carbohydrate metabolism evaluation, and hematology. Physical exam including clinical assessments of facial hair and acne were monitored.
