The
correct answer is urethra.
In
males, the urethra is a tube that connects the urinary bladder to the urinary
meatus (opening) for the removal of urine from the body but it also travels
through the penis and carries semen which means that is part of both, urinary
and reproductive systems. Males use urethra for urination and ejaculation and
thus they contain external urethral sphincter and internal urethral sphincter
muscle.
