What this trial studies

This study evaluates the impact of genital gender-affirming surgery on genital sensitivity and sexual functioning in individuals with gender dysphoria. It involves transgender males and females who wish to undergo surgeries such as phalloplasty, metoidioplasty, vaginoplasty, or vulvoplasty. Participants will undergo Semmes-Weinstein monofilament testing and complete questionnaires to assess their outcomes post-surgery. The goal is to better understand the relationship between surgical techniques and sexual function outcomes.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into improving sexual function and satisfaction for transgender individuals post-surgery.

How similar studies have gone: While there have been studies on urological outcomes, this specific focus on genital sensitivity and sexual function post-surgery is relatively novel.
