Efficacy of oral estrogen plus testosterone gel to improve sexual function in postmenopausal women

Preparation and In Vitro and In Vivo Evaluation of a Testosterone Film Forming Gel for the Treatment of Hypoactive Sexual Desire Disorder in Women

Hypoactive sexual desire disorder (HSDD) is one of the most common sexual complaints in women. Currently, there is an unmet need for a drug treatment for this disorder. The purpose of this study was to develop a testosterone (TS) film forming gel used for women to treat HSDD by measuring the tackiness, peel adhesion force, tensile strength, and elasticity of the formulation. Diethylene glycol monoethyl ether (Transcutol P), an efficient penetration enhancer, was added to the optimized formulation and the transdermal permeation characteristics in vitro were studied using Franz-diffusion cells. The quantitative determination of TS was performed by high-performance liquid chromatography (HPLC). After 24 h, Transcutol P at 3% had the largest cumulative amount of drug and enhancement ratio of TS of 75.14 μg/cm² and 2.82, respectively. After the screening of film forming polymers and penetration enhancers, the optimal formulation was as follows: glycerol (1%, w/w); 12.5% sodium carboxymethylcellulose (CMC-Na) aqueous solution (0.5%, w/w); 2.5% Carbomer ethanol solution (0.5%, w/w); Transcutol P ethanol solution (3%, w/w) containing 0.5% TS; and 8% Poly vinyl alcohol (PVA) aqueous solution (30%, w/w). The optimized film forming gel had good uniformity and the release of TS in vitro was close to 100% within 24 h. In vivo studies showed the formulations had optimal area under blood drug concentration curve values in the order of 3% Transcutol P > 1% Transcutol P > 5% Transcutol P > control preparation. The formulation with 3% Transcutol P provided the highest permeation effect both in vitro and in vivo. The safety of this formulation was further evaluated with a skin irritation test. It could effectively improve the rabbit skin irritation observed with a marketed transdermal patch Androderm®. The present study provides a promising approach for the development of a novel TS film forming gel for the treatment of HSDD in women.

Effect of Zinc on Testosterone Levels and Sexual Function of Postmenopausal Women: A Randomized Controlled Trial

This study aimed to investigate the effect of zinc supplementation on testosterone levels and sexual function in postmenopausal women. This randomized clinical trial was performed on 116 postmenopausal women with serum zinc levels below 62, and low sexual function who were randomly divided into two groups: intervention and control. Serum zinc levels, testosterone, hemoglobin and hematocrit, as well as their Female Sexual Function Index (FSFI) were evaluated before and after the intervention. Data analysis was performed using paired and independent t-tests, Fisher's exact test, and Chi Square test. The use of zinc supplementation in the intervention group significantly improved sexual desire, arousal, orgasm, satisfaction, vaginal moisture, and pain during intercourse and also the overall score of sexual function compared to the control group (p < 0.001). Zinc supplementation in the intervention group, resulted in a significant increase in testosterone levels compared to the control group, which improved sexual function in postmenopausal women non-significantly. The results of this study showed that zinc supplementation can improve testosterone levels and sexual function in postmenopausal women. Using this supplement in postmenopausal women having zinc insufficiency is recommended. Also, there is need for more studies to prove the effect of zinc on testosterone and sexual function.

Sexual behaviors and function during menopausal transition-does menopausal hormonal therapy play a role?

OBJECTIVES

The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an "end all" in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors.

METHODS

A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls-MHT non-users (n = 103). Diagnostic and Statistical Manual of Mental Disorders -five criteria were used to assess sexual dysfunction. Sexual problems were evaluated by the Changes in Sexual Function Questionnaire (CSFQ), body image by Body Exposure during Sexual Activity Questionnaire, and quality of relationship by the Well-Match Relationship Questionnaire. Logistic regression was used to determine the risk factors for FSD and sexual problems.

RESULTS

Women using MHT had higher body esteem during sexual activities, better sexual function (CSFQ) in all domains except desire/interest, better quality of relationship, and lower prevalence of FSD and sexual complaints (CSFQ) except arousal/excitement problems. However, self-rated effects of MHT on sexual behaviors showed that MHT did not play a major role. Women with secondary and higher education (OR = 0.09, CI: 0.02-0.4; P < 0.01 and OR = 0.2, CI: 0.05-1.0; P < 0.05, respectively) and with a higher number of lifetime sexual partners (OR = 0.6, CI: 0.4-0.9; P < 0.01) were less likely to have FSD. In contrast, individuals with more anxious behaviors during sexual activity (OR = 3.2, CI: 1.3-7.3; P < 0.01) and with more severe menopausal symptoms (OR = 1.1, CI: 1.0-1.2; P < 0.001) were more likely to have FSD. Using MHT was not associated with that risk nor with sexual function.

CONCLUSION

In women during menopausal transition, sexual behaviors were different in MHT users compared with non-users. However, in this cross-sectional observational study conducted in 210 women between the ages of 45 to 55 years, using MHT was not associated with modification of sexual function, decreasing the risk of sexual dysfunction, nor sexual problems.
