A meta-analysis on the influence of voiding position on urodynamics in males with lower urinary tract symptoms showed that in the sitting position, the residual urine in the bladder was significantly reduced, the maximum urinary flow was increased, and the voiding time was decreased. For healthy males, no influence was found on these parameters ...
The protection provided by the foreskin for the glans penis and meatus has been recognized since 1915. In the absence of the foreskin the meatus is exposed to mechanical and chemical irritation from ammoniacal diaper (nappy) that produces blister formation and ulceration of the urethral opening, which eventually gives rise to meatal stenosis (a narrowing of the opening).

Hold your urine for too long, and—ready or not—it's going to start coming out. "The longer the bladder is full, the greater the likelihood of leakage of urine," Dr. Fromer says.
Men with prostatic hypertrophy are advised to sit down whilst urinating. [18] A 2014 meta-analysis found that, for elderly males with LUTS, sitting to urinate meant there was a decrease in post-void residual volume (PVR, ml), increased maximum urinary flow (Qmax, ml/s), which is comparable with pharmacological intervention, and decreased the ...

A full bladder is known to mildly stimulate nerves in the same region. The possibility of a full bladder causing an erection, especially during sleep, is perhaps further supported by the beneficial physiological effect of an erection inhibiting urination, thereby helping to avoid nocturnal enuresis [citation needed].
Reasons for nighttime urination There are many reasons for frequent nighttime urination — it's often multifactorial and requires some investigation to get to the root cause, says Lloyd-Harris.
Symptoms may include frequent urination, trouble starting to urinate, weak stream, inability to urinate, or loss of bladder control. [17] Complications can include urinary tract infections, bladder stones, and chronic kidney problems. [18] Prostatitis is inflammation of the prostate gland.
