The prostate is a gland located in the male reproductive system, situated below the bladder and in front of the rectum
. It plays a crucial role in the production of semen, which is a fluid that, along with sperm cells from the testicles and fluids from other glands, makes up the seminal fluid
. The prostate's main functions include:
- Producing fluid for semen : The prostate produces a fluid that mixes with sperm from the testicles to create semen
. This fluid is stored in two tube-shaped glands called the seminal vesicles, which are found just behind the bladder
- Forcing semen through the urethra : The muscles of the prostate ensure that the semen is forcefully pressed into the urethra, which passes through the prostate
. During ejaculation, these muscle cells contract and forcefully press the stored fluid, causing it to combine with sperm cells and other fluids to form semen, which is then released
- Regulating urine flow : The prostate surrounds the urethra, which is the tube that empties urine from the bladder
. As a man ages, the prostate tends to increase in size, which can cause the urethra to narrow and decrease urine flow, a condition known as benign prostatic hyperplasia
The prostate is made up of connective tissues and glandular tissues, and it is controlled by the sex hormone testosterone, which is made by the testicles
. Testosterone is responsible for functions such as sex drive, erections, and muscle development
