Penis Disorders - What penis disorders are there? Here are a few disorders that affect the penis that I have studied, there are more but these seem to be the ones most men, especially in penis enlargement, are concerned with.
Priapism: Priapism is a constant, sometimes agonizing erection. The erection can last for a few hours to a few days (in rare cases). An erection caused by priapism is not sexually derived nor will it be relieved by ejaculation. Priapism happens when blood fills into the penis but does not drain. (see penis anatomy)
Peyronie’s disease: Peyronies is a disorder where a plague will build up in the walls of the penis. The plaque, which usually manifests as a lump or crease in the penis (most noticed during erection). In many cases the hardening of this plaque results in a bend in the penis during an erection. This condition can make it painful to achieve an erection.
Balanitis: Balanitis is a swelling of the foreskin (the skin that covers the head (glans) of an uncircumcised penis. When the head of the penis also swells the condition is called balanoposthitis. Some of the common side effects of this are redness, itching and a foul smelling discharge. (see penis anatomy)
Phimosis is when the foreskin of the penis is too tight and cannot be retracted. When this happens the head of the penis is unable to come out. (see penis anatomy)
This is a very rare condition. Penis cancer happens when atypical cells divide and grow uninhibited. (see penis anatomy)
