Abstract

OBJECTIVE:

The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women.

METHODS:

This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires.

RESULTS:

There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6 ± 3.2) and Tribulus (10.2 ± 3.2) groups in the domains of desire and sexual interest (p ≤ 0.001), foreplay (3.3 ± 1.5 versus 4.2 ± 1.0) (p ≤ 0.01), arousal and harmonious interaction with the partner (5.7 ± 2.1 versus 7.2 ± 2.6) (p ≤ 0.01), and comfort in sexual intercourse (6.5 ± 2.4 versus 8.0 ± 1.9) (p ≤ 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28). In the FIEI questionnaire, there was a significant improvement (p < 0.001) in the domains of vaginal lubrication during coitus and/or foreplay (20 versus 83.3%), sensation in the genitalia during sexual intercourse or other stimuli (16.7 versus 76.7%), sensation in the genital region (20 versus 70%), sexual intercourse and/or other sexual stimulations (13.3 versus 43.3%), and the ability to reach orgasm (20% versus 73.3%). There was no significant difference in adverse effects between the two groups.

CONCLUSIONS:

After 90 days of treatment, at the doses used, we found Tribulus terrestris to be effective in treating sexual problems among menopausal women.
