Sexual dissatisfaction is one of the main motivations for seeking female genital cosmetic surgery (FGCS), though the outcomes of such surgeries are controversial. Evaluation of the sexual function, satisfaction, and assertiveness in FGCS groups. From five clinical centers in Tehran, Iran, 200 women in the study group (women seeking or had undergone labiaplasty (LP), women seeking or had undergone multi-procedure (MP) of FGCS simultaneously) and the control group were randomly selected. Participants completed the Female Sexual Function Index (FSFI), the Global Measure of Sexual Satisfaction (GMSEX), and the Hurlbert Index of Sexual Assertiveness (HISA). The groups were compared using the Chi-square, one-way ANOVA with post hoc analysis. In women seeking LP, the mean FSFI, GMSEX, and HISA score was lower than that of women who had undergone LP (FSFI: 18.41 vs 21.36, p =0.04, GMSEX: 20.36 vs 28.03 p <0.001, HISA: 49.7 vs 62.5 p <0.001). Our finding showed as well that women seeking MP also had lower mean FSFI, GMSEX, and HISA scorecompared to women had undergone MP (FSFI: 23.02 vs 18.02, p <0.001, GMSEX: 19.63 vs 28.94 p <0.001, HISA: 45.72 vs 60.62 p <0.001). Women who had completed FGCS experienced better sexual function, satisfaction, and assertiveness compared with women seeking surgery.
