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.

Prostatitis

Prostatitis is an inflammation of the prostate gland, often resulting in swelling or pain. Prostatitis can result in four significant symptoms: pain, urination problems, sexual dysfunction, and general health problems, such as feeling tired and depressed. The prostate is a reproductive gland located just below the bladder and in front of the rectum. It wraps around the urethra, a tube that carries urine from the bladder. The prostate produces most of a male’s semen.
