Effects of Glycine max (L.) Merr. soy isoflavone vaginal gel on epithelium morphology and estrogen receptor expression in postmenopausal women: A 12-week, randomized, double-blind, placebo-controlled trial

OBJECTIVE Evaluate the effects of vaginal administration of isoflavones derived from Glycine max (L.) Merr. as a treatment option for vaginal atrophy, on the morphology and expression of estrogen receptors in vaginal epithelium of postmenopausal women. METHODS The double-blind, randomized, placebo-controlled, clinical trial. Sixty women were treated for 12 weeks with isoflavone vaginal gel 4% (1g/day) and a placebo gel. After 4 and 12 weeks, the vaginal atrophy symptoms were classified at none, mild, moderate and severe and the vaginal cytology were taken to determine the maturation value. Vaginal pH was measured at the beginning and end of therapy. Microbiopsies in vaginal fornix were performed before the treatment and after 12 weeks of treatment. RESULTS Isoflavone vaginal gel was effective for relief of vaginal dryness and dyspareunia symptons and an increase in the intermediate and superficial cells was noted. The vaginal pH in the isoflavone group was 7.1 at baseline and 5.4 after 12 weeks, whereas in the placebo group there was no significant change. A significant increase in thickness after treatment was detected in the Isoflavone Group. The percentage of estrogen receptor positive cells in vaginal epithelium for the Isoflavone Group ranged from 58.5% at the beginning of treatment to 82.6% after 12 weeks. These results were superior to placebo gel. CONCLUSION Glycine max (L.) Merr. at 4% vaginal gel on a daily basis in postmenopausal women led to improvements in vaginal atrophy symptoms, maturation values, vaginal pH, morphology and expression of estrogen receptors in vaginal epithelium. Isoflavones proved good treatment options for relief of vulvovaginal atrophy.

Assessment of the Effects of Tribulus Terrestris on Sexual Function of Menopausal Women

OBJECTIVE The aim of this study was to study the effects of Tribulus terrestris on sexual function in menopausal women. METHODS This was a prospective, randomized, double-blind, placebo-controlled clinical trial that included 60 postmenopausal women with sexual dysfunction. The women were divided into two groups, placebo group and Tribulus group, and evaluated by using the Sexual Quotient-female version (SQ-F) and Female Intervention Efficacy Index (FIEI) questionnaires. RESULTS There was no significant difference between the groups in age, age at menopause, civil status, race, and religion. In the evaluation with the SQ-F questionnaire, there were significant differences between the placebo (7.6 ± 3.2) and Tribulus (10.2 ± 3.2) groups in the domains of desire and sexual interest (p ≤ 0.001), foreplay (3.3 ± 1.5 versus 4.2 ± 1.0) (p ≤ 0.01), arousal and harmonious interaction with the partner (5.7 ± 2.1 versus 7.2 ± 2.6) (p ≤ 0.01), and comfort in sexual intercourse (6.5 ± 2.4 versus 8.0 ± 1.9) (p ≤ 0.01). There was no significant difference between the placebo and Tribulus groups in the domains of orgasm and sexual satisfaction (p = 0.28). In the FIEI questionnaire, there was a significant improvement (p < 0.001) in the domains of vaginal lubrication during coitus and/or foreplay (20 versus 83.3%), sensation in the genitalia during sexual intercourse or other stimuli (16.7 versus 76.7%), sensation in the genital region (20 versus 70%), sexual intercourse and/or other sexual stimulations (13.3 versus 43.3%), and the ability to reach orgasm (20% versus 73.3%). There was no significant difference in adverse effects between the two groups. CONCLUSIONS After 90 days of treatment, at the doses used, we found Tribulus terrestris to be effective in treating sexual problems among menopausal women.

Avaliação da função sexual em mulheres após a menopausa portadoras de síndrome metabólica

PURPOSE To evaluate sexual function in postmenopausal women diagnosed with metabolic syndrome. METHODS Case-control study with 195 postmenopausal women (amenorrhea ≥1 year, FSH≥30 mIU/mL, aged 43 to 69 years) seen at the Department of Obstetrics and Gynecology, School of Medical Sciences of Santa Casa de São Paulo and in the Basic Units of the Family Health Program of São Paulo. Clinical data were collected, and body mass index and waist circumference were evaluated. Total cholesterol, HDL and LDL cholesterols, triglycerides, and fasting glucose were determined for biochemical analysis. We considered women to have the metabolic syndrome when they met three or more diagnostic criteria: waist circumference>88 cm and triglycerides ≥150 mg/dL; cholesterol HDL <50 mg/dL; blood pressure ≥130/85 mmHg, and fasting glucose ≥110 mg/dL. The participants were divided into Control Group (n=87) and Metabolic Syndrome Group (n=108). The Female Sexual Function Index (FSFI) was employed to assess the sexual function. RESULTS Mean age was 54.0 ± 4.7 years. The rate of sexual dysfunction was significantly higher in women with the metabolic syndrome than in the Control Group, both when considering FSFI <26.5 (90/108 [83.3%] versus 42/87 [48.2%], p<0.0001) and FSFI <23 (62/108 [57.4%] versus 16/87 [18.39%], p<0.001). The domains desire, arousal, lubrication, orgasm (p<0.001), and satisfaction (p=0.002) had lower scores in women with the metabolic syndrome. For the pain scores, there was no significant difference (p=0.57) between groups. All components of the metabolic syndrome diagnosis were associated with higher levels of sexual dysfunction (p<0.001). CONCLUSION Postmenopausal women with metabolic syndrome present more frequently sexual dysfunction than those of the same age who do not have it.

Effects of low dose of tibolone on steroid receptors and Bcl-2 on the postmenopausal endometrium.

OBJECTIVE A prospective randomized controlled trial was conducted to evaluate the effect of low dose of tibolone on the histology, expression of estrogen (ER) and progesterone receptors (PR) and Bcl-2 protein, in endometrium of postmenopausal women. METHOD Forty postmenopausal women consented to treatment and were allocated into two groups of 20 women: Group 1 (Control) without hormone replacement therapy (HRT); Group 2 (Tibolone) treatment at the dose of 1.25 mg/day of oral tibolone administered for a 24-week period. The effect on the endometrium was assessed by histology and the apoptosis marker Bcl-2. The immunoexpression of ER and PR were also measured. RESULTS Tibolone group showed higher expression of ER, PR and Bcl-2 protein in glandular epithelium and stroma compared to control group. CONCLUSION Tibolone in a daily dose of 1.25 mg during 24 weeks demonstrated endometrial action that resulted in low proliferation and was shown to lead to atrophic endometrium. It had favorable effects on the postmenopausal endometrium due to its higher immunoexpression of PR and Bcl-2 protein in endometrial glandular epithelium, thereby creating a balance between pro-apoptotic and anti-apoptotic actions.
