Assessment of the Effects of Tribulus Terrestris on Sexual Function of Menopausal Women

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