Background

The prostate gland is the organ of the gonads characteristic of men. The prostate is an unpaired parenchymal uterus, consisting of glandular and muscular tissues. The prostate is like chestnut, with its bottom facing upwards, and is attached to bladder, with its tip facing downwards, and is applied to urogenital diaphragm, and the front is attached to pubic bone, and the back is located in rectum, so that when there is prostate swelling, the digital diagnosis of rectum can be performed to palpate the back of prostate. The middle of the prostate gland is penetrated by the urethra, and the upper orifice of the urethra is held, so that the prostate is diseased and urination is affected first.

The prostate gland is a sexual secretory gland which is very rare in human bodies and has a double secretory function of internal secretion and external secretion. As an exocrine gland, the prostate gland secretes about 2 ml of prostatic fluid every day, which is the main component constituting semen; the hormone secreted by the prostate gland, which is an endocrine gland, is called "prostaglandin".
