Women are the largest segment — they have higher rates of pelvic floor dysfunction and are more likely to seek help. But men are the fastest‑growing segment. The underactive bladder market forecast shows that the male segment is growing at over 7% CAGR, driven by better awareness and screening for prostate‑related voiding issues.

What's different? In men, underactive bladder is often linked to prostate enlargement or neurological conditions (diabetes, Parkinson's). The underactive bladder market analysis notes that the fastest‑growing category is overactive bladder medications (used off‑label to relax the sphincter), but evidence is weak.

Women's UAB is often related to childbirth, pelvic organ prolapse, or ageing. They're more likely to try behavioural therapy (timed voiding, double voiding) before drugs.

The bottom line: UAB affects both genders, but the underlying causes differ. A good urologist will tailor treatment to your specific anatomy and history.
