Vitagnus an estrogen-riched herbal remedy used in sexual dysfunction: A randomized clinical trial

BACKGROUND: Sexual dysfunction is a common problem in the postmenopausal period. Vitagnus is a phytoesterogen containing herb, which can bind to estrogen receptors and modulate their function. In this study, we evaluated the efficacy of oral vitagnus solution on sexual dysfunction improvement among postmenopausal women in North Khorasan Province, Iran. MATERIALS AND METHODS: The present study was a double-blind clinical trial on 60 retired female teachers who visited the retirement center of North Khorasan Province from December 2019 until January 2021. Sampling was done in a convenience sampling. Allocation of intervention and placebo groups was done randomly by marking as A and B codes, respectively. Eligible married women aged 50–70 years had received 40 drops of vitagnus or placebo daily for 8 weeks. Female Sexual Function Index was filled on the first day, fourth, sixth, and eighth week after the intervention. Data were analyzed using SPSS V.23 and independent t-test, Mann–Whitney U, Chi-square, Fisher's exact test, and repeated measure ANOVA were used for analyzing descriptive and inferential data. P < 0.05 was considered as a statistically significant threshold. RESULTS: Data from Bonferroni post hoc test indicated that the mean total sexual function did not differ between the two groups before and at the end of the fourth week of intervention, but scores of total sexual function showed a significant difference at the end of the sixth (P = 0/003) and eighth week (P = 0/001) of intervention. CONCLUSION: Vitagnus drops, as a simple, cheap, and available herbal supplement, could affect the sexual function of women aged 50–70 and improve it.
