The benefits of androgens combined with hormone replacement therapy regarding to patients with postmenopausal sexual symptoms

Abstract

Objective: To evaluate the benefits and risks of hormone replacement therapy (HRT) combined with methyltestosterone (MT) in postmenopausal women with sexual dysfunction.

Design: This study was a randomized, double-blind, placebo-controlled and crossover trial. Eighty-five women using HRT were divided into four treatment groups: GI-HRT plus placebo for 4 months; GII-HRT plus MT 2.5mg/day for 4 months; GIII-HRT plus placebo for 2 months and then replaced with HRT plus MT 2.5mg/day for 2 months; GIV-HRT plus MT 2.5mg/day and then replaced with HRT plus placebo for 2 months. Blood was collected at baseline, after 2 months (T1) and 4 months (T2) of treatment for hormone determinations of estradiol, FSH, total and free testosterone, GOT, GPT, glucose, total and fractions of cholesterol and triglycerides. All participants answered clinical questions and a validated questionnaire of modified McCoy's sex scale.

Results: The association of HRT with MT 2.5mg/day did not significantly change liver enzymes or increase cardiovascular risk factors. The patients of GII, GIIII and GIV when using MT presented amelioration of sex symptoms, mainly satisfaction and desire (p<0.01); however, GIII at T1 (1.3+/-0.3) presented similar problem score results as compared to GIII at T2 (1.5+/-0.6).

Conclusion: All data suggest that combined HRT-androgen therapy may be beneficial for postmenopausal women receiving HRT who continue to complain of sexual difficulties or for postmenopausal women with sexual complaints who are not undergoing estrogen therapy.
