The urethra runs from the Bladder to the end of the penis. so it will be an inexact length, and will extend and contract with erections.
The common length is about 3" from the base of the penis to the bladder then add the length of the penis. so in a flaccid male it would be approximately 6-8" total length.
Urethra has three regions in males, the prostatic urethra, membranous urethra, and the spongy urethra.
In males, the urethra carries semen as well as urine.
The urethra is part of the reproductive and urinary system of the male.
The bladder feeds into the Urethra. The urethra leads into the penis in males and into the vagina in females.
In males, the urethra expels both urine and sperm. In females, the urethra expels only urine.
In males, it is the tube that conducts urine from the bladder through the penis to the outside of the body and it also conducts the semen from the reproductive organs for release in ejaculation.
In both genders, the urethra transports urine. In men, the urethra also transports semen which contains sperm cells and can impregnate a woman. In males, the urethra takes a detour through the prostate gland and seminal vesicles, so their urethrae are used for urination and ejaculation.
