This study aimed to review the current knowledge on sexual dysfunction in men and women with hyperthyroidism through a systematic review and meta-analysis. Available clinical trials from the MEDLINE database were searched using a prerecorded protocol (Protocol Prospero ID: CRD42022340587), and obtained data were analyzed and reported according to the PRISMA guidelines. Pooled effect estimates were computed using a random-effects model. Twenty eligible studies were identified, of which 15 were included in this meta-analysis. The prevalence of erectile dysfunction was significantly higher in participants with hyperthyroidism than that in controls [odds ratio = 9.16 (95% confidence interval [CI], 5.0–16.5)]. Treatment of hyperthyroidism alone improved erectile functions [effect size, ES = 0.36 (95% CI, −0.01–72)] and mean intra-vaginal ejaculation latency time [ES = 0.63 (95% CI, 0.27–98)] among men with erectile dysfunction and/or premature ejaculation. The prevalence of premature ejaculation also decreased with treatment of hyperthyroidism [odds ratio = 0.11 (95% CI, 0.04–28). Women with hyperthyroidism demonstrated higher odds in female sexual dysfunction than controls [odds ratio = 4.34 (95% CI, 2.63–7.18)]. Female sexual function index scores in women with hyperthyroidism were also significantly lower than those in the controls with moderate effect sizes. An evident and reversible disruption of sexual functions under hyperthyroidism conditions was observed in both sexes.
