The urethra is the tube through which urine passes to be eliminated from the bladder, and in males, it also carries the semen in ejaculation. It runs from the base of the bladder to the tip of the penis in males. The vas deferens that carries semen connects with it near the prostate gland where there is a valve that allows either the passage of urine or the passage of semen in men. The average length is about 8 inches (20 cm) in adult males. It can range in length from approximately 15 cm to 29 cm. It is only around 1.5 inches in females.
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.
