Ask a question
The penis is the male organ of reproduction and elimination of urine.


The penis is the name for the male reproductive organ located at the pubis. It contains the male urethra, a tract which has two functions: transporting urine from the bladder to outside of the body, and ejaculating sperm containing masculine gametes called spermatozoa, the male reproductive cells. The penis comprises elements called the corpus cavernosum, which fill with blood when the individual is sexually excited, rendering the penis rigid and enabling sexual activity. At the end of the penis there is the glans, usually covered by a protective layer of skin called the foreskin, and containing the orifice of the urethra at its end.

Micro penis

A micro penis or micro phallus is a small penis, measuring at adulthood, less than 2 inches in its erect state. Reproductive capacity remains normal in most cases, but a micro penis can cause psychological problems with complexes in men. The sex lives of affected men is often altered. In most cases, the problem of development of the penis is caused by a hormonal problem such as androgens or a genetic disease. Typically detected at birth in some genetic diseases or relatively early in the development of the child in the context of a hormonal abnormality, micro penis can sometimes be corrected by the administration of compensatory hormones.

Penis enlargement

Its length varies according to the individual, which can be a source of complexes for certain men. Penis enlargement is the extension of the penis' dimensions through surgery. The intervention consists of severing the suspensory ligament of the penis, a ligament that serves to keep the organ in a horizontal position, notably during erection.
