Notes for this study:
||Female Sexual Function Index questionnaire: Intervention group: 2.04 pre, 3.66 post for desire. Placebo group: 1.95 pre 3.15 post.
|Number of Subjects
||30-44, 45-64, 65+
45 postmenopausal women were recruited and randomly assigned to either 750 mg per day (divided into 3 equal doses) or placebo for 120 days. According to the Female Sexual Function Index questionnaire, there was no significant difference between groups in any of the measures of libido and sexual satisfaction or the combined ratings. Women taking Tribulus Terrestris reported significantly fewer sexual problems on the Sexual Quotient Female Version questionnaire than women taking placebo. Free and bioavailable testosterone increased in the group taking Tribulus Terrestris, but total testosterone didn't reach statistical significance. The placebo group saw no significant changes in testosterone. 9 out of the original 45 participants dropped out of the study for personal reasons or due to nausea. There was no difference between groups in the number dropping out due to nausea.
