Prostate
The prostate is a gland of the male body that adds part of the fluid to semen. A healthy human prostate is slightly larger than a walnut. It surrounds the urethra just below the urinary bladder.

Prostate cancer is one of the most common cancers affecting elderly men in developed (also known as first world) countries and a major cause of death. Regular rectal exams are recommended for older men to detect prostate cancer early. Prostate cyst is very common in men. With age, the risk of developing this disease increases significantly. A cyst is a kind of cavity formed from the tissue of the prostate itself, inside which fluid accumulates.[1]
The prostate is often referred to as the male G-spot, which is a spot inside the female vagina that causes intense pleasure when it is stimulated. The prostate can be massaged by using a finger or during anal sex. Some males are able to orgasm with prostate stimulation alone.
