Urinary Tract Male

In the human male, the urethra is about 8 inches (20 cm) long and opens at the end of the penis. The urethra provides an exit for urine as well as semen during ejaculation. The urethra is divided into four parts in men, named after the location:
1. Pre-prostatic urethra: This is the intramural part of the urethra and varies between 0.5 and 1.5 cm in length depending on the fullness of the bladder.
2. Prostatic urethra: Crosses through the prostate gland. There are several openings: (1) the ejaculatory duct, (2) several prostatic ducts, (3) the prostatic utricle.
3. Membranous urethra: A small (1 or 2 cm) portion passing through the external urethral sphincter. This is the narrowest part of the urethra. It is located in the deep perineal pouch. The bulbourethral glands (Cowper's gland) are found posterior to this region but open in the spongy urethra.

Testicular tumor

Testicular cancer typically develops in one or both testicles in young men. It is a highly treatable and usually curable type of cancer. The testicles (also called the testes; a single testicle is called a testis) are part of the male reproductive system. These 2 organs are each normally somewhat smaller than a golf ball in adult males and are contained within a sac of skin called the scrotum. The scrotum hangs beneath the base of the penis.
