Squill oil for decreasing dyspareunia and increasing sexual satisfaction in menopausal women: A triple-blind randomized controlled trial

OBJECTIVE: The present study aimed to investigate the effect of squill oil on dyspareunia and sexual satisfaction in menopausal women. MATERIALS AND METHODS: The present triple-blind randomized two-group controlled trial was conducted on 60 menopausal women (n=30 in placebo group and n=30 in squill oil group) in Mashhad in northeast of Iran in 2019. The Sabbatsberg Sexual Self-Rating Scale and Marinoff dyspareunia scale were the main tools used in this study. The participants were randomly assigned to two groups namely, squill oil group and placebo group and they received the treatments for 4 weeks. Questionnaires were completed before and 4 weeks after the intervention in both groups. Data analysis was performed using SPSS 24 by Mann-Whitney, t-test, and repeated measures ANOVA with a significance level of less than 0.05. RESULTS: The average age in the squill oil group and placebo group were 53.5±2.2 and 51.7±4.5 years, respectively. There was a significant difference (p<0.001) between the two groups in terms of dyspareunia score before (1±3.6 vs 1±3.5) and after intervention (0.7±0.1 vs 1.2±1.2) in two groups. Results of independent t-test indicated that there was a significant difference (p<0.001) between the two groups in terms of sexual satisfaction before (23.4±5.7 vs 23.1±2.8) and after intervention (36.5±5.6 vs 24.8±2.5) in two groups. CONCLUSION: Using squill oil can cause a reduction in painful sexual intercourse and an increase in sexual satisfaction in postmenopausal women.
