main function is to
produce fluid for semen, which transports sperm. During the male orgasm
(climax), muscular contractions squeeze the prostate's fluid into the
urethra. Sperm, which are produced in the testicles, are also propelled
into the urethra during orgasm. The sperm-containing semen leaves the
penis during ejaculation.
Pathophysiology: Although not
technically part of the urinary system, the prostate gland is important
to the urinary health. That's because the prostate surrounds the top
portion of the tube that carries urine from the bladder (the
urethra). Normally, the location of the prostate gland isn't
a problem. But infection or inflammation can cause the gland
to swell, squeezing the urethra and affecting the ability to
urinate. That's exactly what happens in prostatitis,
although the cause of the inflammation depends on the type
of prostatitis. |
