Plain English Summary
Background and study aims
Women with low sexual desire may have problems when starting or having stable sexual relationships, and they may feel unsatisfied and experience marital disorders. Studies have demonstrated that women with low desire, low excitement, or sexual pain are clearly associated with negative feelings regarding their physical and emotional satisfaction, as well as their happiness. In addition, women suffering from those problems tend to experience much more negative emotions and psychological states than women with normal sexual activity.
Our objective was to study the effect of an extract with natural components on women with low sexual desire.
In this study, the multi-ingredient food supplement, Libicare®, has shown an improvement in desire, arousal, lubrication, orgasm, and sexual satisfaction domains, with a clear increase in free testosterone numbers and a decrease in SHBG levels in postmenopausal women.
Who can participate?
Postmenopausal women aged ≥ 45 and ≤ 65 (no natural menses for at least 1 year), with a stable partner and at risk of sexual dysfunction according to score of validated questionnaire.
What does the study involve?
All women were included at routine clinical visits and were treated with 2 tablets of Libicare®, one every 12 hours, daily for 2 months (9 weeks). Libicare® is an oral food supplement containing dry extracts of Trigonella foenum graecum, Turnera diffusa, Tribulus terrestris, and Ginkgo biloba.
What are the possible benefits and risks of participating?
All the participants have been informed, before their inclusion, of the possible risks and benefits, and of all the aspects of the study and have signed an Informed Consent expressing their willingness to participate.
Possible benefits: improving in sexual function.
Possible risks: due to characteristics of Libicare ingredients important risks were not expected.
Where is the study run from?
Instituto Palacios de Salud y Medicina de la Mujer, Madrid, Spain
When is the study starting and how long is it expected to run for?
August 2017 to November 2018

Female sexual dysfunction.
All women were included at routine clinical visits and were treated with 2 tablets of Libicare®, one every 12 hours, daily for 2 months (9 weeks). Libicare® is an oral food supplement containing dry extracts of Trigonella foenum graecum, Turnera diffusa, Tribulus terrestris, and Ginkgo biloba. Libicare® is manufactured by Procare Health (Barcelona, Spain).
All participants were visited at baseline (initial visit) and after 9 weeks (final visit).
Primary variable: Total score of Female Sexual Function Index (FSFI) at 9 weeks vs baseline.
Secondary variables: FSFI score for each domain, and levels of free testosterone and sex hormone binding globulin at 9 weeks vs baseline.
Serum levels of free testosterone and sex hormone-binding globulin (SHBG) were measured in the LABCO Laboratory. SHBG was measured with chemiluminescent immunoassay Immulite 2000 XPi (Siemens Healthcare Diagnostics, Eschborn, Germany). The estimation of serum free testosterone hormone levels was carried out using the ELISA technique (The DiaMetra Italy kit (DKO-015))
Primary outcome measure
Sexual function measured using Female Sexual Function Index (FSFI) at 9 weeks vs baseline.
Secondary outcome measures
1. FSFI score for each domain at 9 weeks vs baseline.
2. Levels of free testosterone and sex hormone binding globulin at 9 weeks vs baseline.

Basic results (scientific)
FSFI results are shown in Table below, which features the mean of baseline values and values after two months, with their standard deviations, of each domain, as well as global determination. As demonstrated by the results after treatment, values were significant for all domains except for dyspareunia. The domain presenting the highest increase was desire, with p=0.0004. The global domain increased 4.15 (6.14) points on average, with a statistical significance of p=0.0011.

Desire 2.40 (0.96) 3.33 (1.29) 0.93 (1.25) p=0.0004

Testosterone mean change between visits (post-pre) was an increase of 0.09 (SD 0.17) units (p=0.0386); the mean percent change as compared to baseline was 79.3% (p=0.0214).
Mean SHBG change between visits (post-pre) was a decrease of -12.05 (SD 11.48) units (p=0.0001).
