Penis diseases, Phimosis

The penis consists of two corpora cavernosa and the corpus spongiosum, which forms a sheath round the urethra. Each of the corpora cavernosa is surround by a coarse layer of connective tissue. All three corpora together are surrounded by a covering of connective tissue.

Penile deviation
(Congenital) torsion of the penis is a malformation of the penis that can vary greatly in extent.

Phimosis
Phimosis, or narrowing of the foreskin, is a narrowing of the opening of the foreskin. This makes it impossible, or painful, for the foreskin to be drawn back over the glans.

Priapism
This denotes a painful continuous erection of the penis that lasts more than two hours, and leads to erectile dysfunction if it is not treated. Immediate treatment is therefore essential in order to guard against permanent damage.

Erectile dysfunction (ED)
The term is used for erection and potency problems (colloquially, ‘impotence’) when, over an extended period of time, a man does not usually succeed in achieving or maintaining an erection of the penis sufficient for satisfactory sex-life. Short-term erection problems do not constitute ED.
