Anatomy & Physiology

The external male sexual anatomy constitutes of the penis, scrotum (which holds the testes) and the perineum. The penis consists of the copora cavernosa and the corpus spongiosum which are involved in erections. The testes produce and store sperm, and the perineum is the area between the scrotal sac and the anus, and is highly sensitive.

Internally, the male sexual anatomy also includes the vas deferens, ejaculatory ducts and urethra, which are involved in the transport of semen. The seminal vesicles produce a fluid that supports sperm, providing a medium through which it can reach the oocyte (egg cell), as well as providing an energy-source. The prostate gland is a small structure found under the bladder which produces a fluid that is also released with sperm in order to neutralise the acidity of the vaginal canal.


Hirsuties papillaris

These are harmless skin tags on the penis that are sometimes mistaken for warts. However, they are not sexually transmitted, and are not contagious. They do not cause any symptoms such as pain, itchiness or discomfort but some people find them aesthetically displeasing. They can be removed surgically only if causing significant distress.
