What does prostate do?

It secretes a fluid that keeps sperm alive while protecting them and the genetic code they

carry. The prostate contracts during ejaculation and squirts its fluid into the urethra.


The prostate contracts during ejaculation, closing off the opening between the bladder

and urethra and pushing semen through at speed. Therefore, it is impossible to urinate

and ejaculate at the same time.

What is Prostate?


Only men have a prostate. It is a small gland that sits below the bladder near the

rectum. It surrounds the urethra, the passage in the penis through which urine

and semen pass.


The prostate gland is part of the male reproductive system. It produces most of the

fluid that makes up semen that enriches sperm. The prostate needs the male

hormone testosterone to grow and develop.


The prostate is often described as being the size of a walnut and it is normal for it

to grow as men age. Sometimes this can cause problems, such as difficulty

urinating. These problems are common in older men and not always symptoms or

signs of cancer.
