Prostate

It is a male organ that is located in front of the rectum and below the bladder. It is formed of cells specialized in the production of fluid that makes up part of the semen, which protects and nourishes the sperm. It is formed of two parts. The external portion represents 30 % of the organ. It is constituted by fibro-muscular tissue and is covered by what is known as the capsule, which is a delicate membrane of fibrous tissue. The internal portion, formed by glands and ducts, constitutes the other 70 %. It is divided into two lobes, right and left, which are separated by a midline furrow or depression, which is palpable by means of a digital rectal examination.

Male reproductive organs

The prostate is located below the bladder, behind the pubic bone and in front of the rectum. It surrounds the first part of the urethra, the duct through which urine and semen are expelled. On both sides there are nerves and blood vessels. Below the prostate there is a set of circular muscle fibers that constitute the urinary sphincter; those muscles prevent the release of urine when we cough, laugh, move, or perform physical activity.
