The male urethra is an unpaired somewhat s-shaped fibromuscular tube that is a crucial component of the male genitourinary system, as its function is not limited to just the excretion of urine from the body into the outer environment. The urethra is the final part of the male urinary system and also is an essential component of the male reproductive system. Compared to female urethra, male urethra is much more longer and its course and structure is more complicated, as most of it goes through the penis.
