In human males, the urethra is used for transport of semen and urine.
The urethra is a thin fibromuscular tube through which urine and semen are transported from the bladder and ejaculatory ducts, respectively, to the outer part of the body in human males. The male urethra is made up of several heterogeneous parts which are membranous, prostatic and spongy. The urethra only transports urine in human females.
