Burden of Lower Urinary Tract and Genital Symptoms in Young Transgender Men: Prevalence and Impact on Daily Life

OBJECTIVES: To investigate the prevalence of lower urinary tract symptoms (LUTS) and genital symptoms among transgender men in Japan, and to evaluate their impact on daily life, including limitations resulting from concerns about toilet accessibility. METHODS: We conducted a cross-sectional, single-center survey of assigned-female-at-birth individuals aged 16 years or older who had been approved for gender-affirming hormone therapy at our gender center. A self-administered questionnaire included the Core Lower Urinary Tract Symptom Score (CLSS), vaginal and urethral symptom items, toilet use outside the home, preferences regarding male urinals, and activity restriction related to toilet access. Data were analyzed descriptively, and multivariable logistic regression analyses were performed. RESULTS: Data from 322 participants (median age 33 years) were analyzed. Overall, 80% reported at least one LUTS, 46% reported at least one bothersome symptom, and 14% had a CLSS global quality-of-life (QOL) score of ≥ 4. Vaginal symptoms occurred in 13% of participants, and 2% reported post-micturition leakage. Most participants (62%) did not use male urinals but wished to use them. Activity restriction due to toilet-related concerns, defined as avoiding or limiting activities such as travel, shopping, or going to the cinema, was reported by 20%, and higher total CLSS was associated with both activity restriction and poor urinary-related QOL. CONCLUSIONS: LUTS and genital symptoms are common in young transgender men, and greater LUTS burden is linked to urinary-related QOL impairment and toilet-related activity restriction. These findings highlight the need for targeted clinical care and improved accessibility of public toilets for transgender men.
