Brief Summary

Objective: To study the effects of Lepidium Meyenii in sexual function of postmenopausal women. Method: It will be held a clinical, prospective, randomized, double-blind, placebo-controlled study with 144 postmenopausal women with sexual dysfunction, treated at Menopause Clinic at the Faculty of Medical Sciences of Santa Casa de São Paulo and in the Vale do Sapucai University. All women sign the Consent Form Term. The study will be conducted in accordance with the protocol and principles of the Declaration Helsinki (Version 1996), according to International Conference on Harmonization and Tripartite Guidelines for good clinical practice and regulatory requirements.
