Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The protocol was submitted and approved by the Ethics Committee, Faculty of Medical Sciences Committee Santa Casa de São Paulo. The diagnosis of sexual dysfunction will be done by a sexologist physician experienced and trained in the diagnosis of female sexual disorders through a structured clinical interview, a list of sexual symptoms. It will be oriented to avoid further consumption of diet or another type of herbal medicine during the study. After the interview, signing the Informed Consent and they will be informed about the randomization. Interview with sexological questionnaires will be applied used in Sexology Clinic, Faculty of Medical Sciences of Santa Casa de São Paulo and Vale do Sapucai University, with the purpose of obtaining data sociodemographic. The Female Sexual function Index (FSFI) and the Female Intervention Efficacy Index questionnaire (FIEI). When necessary, the Beck Depression Inventory II (Cunha 2001) will be used to ward off depression, which will be applied by enabled professional. The application will be individually and by the same researcher. The results will be analyzed and interpreted in the light of the theoretical framework of socio-historical psychology, this theory of knowledge, is associated with the understanding of the culture of the structure, social organization and the rescue human subjectivity.
