The purpose of this study is to evaluate the effectiveness of Libicare® in the sexual desire and arousal at 12 weeks in peri or postmenopausal women aged between 40 and 60 years old with low sexual desire and arousal compared with active control.
Despite current consensus in the literature that Female Sexual Dysfunction can manifest at any age in a woman´s life, researchers as Sarrel documented that during menopause, up to 40% of women are experiencing a decrease in their sexual libido. The common assumption is that the menopause contributes to a drop of the sexual desire probably as a result of low production of hormones from ovaries, at the same time will reduce the estrogen and testosterone. This reduction starts to be reduced in the thirties and continues to reduce progressively at a constant rate reaching of about 50% of their initial highest levels by the time they reach menopause. Other hormones could be involved as Sex hormone-binding globulin (SHBG) or dehydroepiandrosterone (DHEA), both are related with testosterone levels.
Libicare® is a dietary supplement whose ingredients could have positive effects on the improvement of sexual function in women with low desire and arousal levels.

The selected patients will be randomly distributed in one of the two arms (Libicare® / active-control), in a 2:1 ratio according to a randomization list. The kits containing the study treatment (Libicare®) and the active-control will be numbered with a randomization code according to this unique list and will be distributed to the consultations.
Patients will not know the treatment and only the researchers and team investigator assigned to the study will know the treatment assigned.
A second randomization list (ratio 1:1) will be generated for Libicare® responding patients, at 12 weeks in order to assign two sub-groups: continue Libicare® treatment or observation without Libicare® treatment.
