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.
