What this trial studies
This observational study investigates the impact of tucking on semen quality in adult trans women, particularly in the context of fertility preservation prior to starting gender-affirming hormone therapy (GAHT). It aims to analyze the effects of tucking, a method used to minimize crotch bulge, on sperm concentration and motility. The study will involve female transgender patients aged 18 to 50 who are eligible for GAHT and will assess their semen quality before and during the practice of tucking. The findings could provide valuable insights into fertility issues faced by trans women.
Why it matters
Potential benefit: If successful, this study could help inform trans women about the effects of tucking on their fertility and guide them in making decisions about fertility preservation.
How similar studies have gone: While there have been studies on semen quality in trans women, the specific focus on tucking and its effects on fertility is relatively novel and has not been extensively tested.
