has your penis always done this or has it
gradually started to curve
Peyronie's (pa-ro-NEEZ) disease causes a
bent penis during erection. A hard,
fibrous layer of scar tissue (plaque)
develops under the skin on the upper or
lower side of the penis. When the penis is
erect, the scar tissue pulls the affected
area off at an angle, causing a curved
penis. The plaque, formed by thickened
layers of soft tissue in the penis is
noncancerous (benign). The condition can
cause pain and make sexual intercourse
difficult.
Sometimes Peyronie's disease improves
without treatment, so your doctor may
initially recommend a wait-and-see
approach. Treatments of Peyronie's disease
involve nonsurgical and surgical
approaches.
The signs and symptoms of Peyronie's
disease may appear overnight or develop
more slowly. These may include:
Painful erection
A bend or curve in your penis during
erection
A thick band of hard tissue on one or more
sides of your penis
Indentation, or an "hourglass-shaped"
penis during erection
Impaired ability to obtain an erection
(erectile dysfunction, or ED)
Shrinking or shortening of your penis
Scar tissue that develops on the top of
the penis will cause the penis to bend
upward. Plaque on the underside of your
penis will cause it to bend downward.
Sometimes scar tissue occurs on both sides
of the penis, causing an indentation or
"bottleneck."
