A clinical trial evaluated the effects of treating postmenopausal women with low libido using Tribulus . All women received testing including mammography, vaginal ultrasounds, and serum levels of prolactin, thyroid stimulating hormone, total testosterone, and sex hormone-binding globulin before enrollment. Study participants were randomized to two groups with the treatment group receiving three pills of 250 mg of Tribulus for 120 days and the control group receiving placebo for 120 days.

The Female Sexual Function Index (FSFI) and the Sexual Quotient Female Version (QS-F) questionnaires were used to assess female sexual function. A total of 36 healthy postmenopausal women with low libido were selected to participate in this study in Brazil. All women were between 1 and 10 years postmenopausal and were between 43 and 65 years old. Women were excluded if they had interpersonal relationship problems or had partners with sexual problems.

A total of 36 women, with 20 in the study group and 16 in the placebo group, with three dropouts in each group. The total mean score and scores of each of the six FSFI questionnaire domains before and after treatment did not show any significant difference between the two groups. Women receiving the Tribulus scored significant improvements in all six domains as did the placebo did, with the exception of lubrication which did not improve in the placebo group.

After 120 days of treatment with Tribulus the QS-F indicated significant improvement in the domains of desire, arousal/lubrication, pain and anorgasmia with the placebo group showing no improvements in any of these domains.

There was a significant increase in the levels of free and bioavailable testosterone in the Tribulus group with no increase in the placebo group.  

Relieves Symptoms of Menopause

A clinical study on Protodioscin, the active ingredient of an herbal plant called Tribulus, has shown that it is very effective in relieving the symptoms of menopause. This study found that 98% of women with natural and induced menopause experienced complete or almost complete disappearance of the symptoms of menopause, including hot flashes, night sweats, mood swings, and excitability.

A subsequent study on Tribulus protodioscin also showed that it can increase the body’s bone-turn-over activity. This suggests that it can help maintain bone health and prevent deterioration because of osteoporosis, in which a woman’s bone becomes increasingly brittle and prone to damage due to the decrease in estrogen level.
