Does one need a prostate gland?

The prostate gland is the size and shape of a chestnut it is located in the close vicinity and below the urinary bladder. It surrounds the upper part of the urethra like a ring and regulates the emptying of the bladder. In all young male adults the prostate weighs about 20 gms. Its main function is to produce a secretion that is the main component of seminal fluid. 

Although the gland intrinsically has nothing to do with the production of semen, a man without a prostate gland is not procreative. However, this does not mean that his sexuality is restricted. His ability to have an erection is independent of the prostate as the nerve tissue involved in an erection is located in the tissue surrounding the prostate. Medication is unnecessary after surgical removal of the prostate, unlike following removal of a hormonal gland, such as the thyroid, 

As a man ages, the prostate gland becomes englarged. This can lead to urinary problems, and in some patients the sexual function may be impaired. This enlargement is referred to as benign growth of the prostate, in medical terms "benign prostate hyperplasia" (BPH). BPH has nothing to do with cancer, but some men with an enlarged prostate may have to undergo surgery to improve urine flow. However, the symptoms and complaints associated with BPH are similar to the symptoms caused by a prostate carcinoma. These symptoms do not usually develop until the prostate carcinoma has reached an advanced stage. A urologist should therefore be consulted should such problems arise.
