How long is the male urethra?
Male urethra is much longer than female urethra as it extends the length of the penis. Male urethra, about 20cm in length, comprises three parts; prostatic, membranous, and spongy. Prostatic urethra runs from the bladder to the part of the urethra where the vas deferens connects.
