‘Initially, when I was told that I had cancer, I had no idea where the prostate was, what it did or anything like that.’

The male reproductive system

The prostate is a small gland below the bladder and in front of the rectum in men. It surrounds the urethra, the passage in the penis through which urine and semen pass. The prostate is often described as the size of a walnut and it is normal for it to get bigger as men age.

The prostate is part of the male reproductive system (see diagram). It produces most of the fluid that makes up semen, which enriches and protects sperm. The prostate needs the male hormone testosterone to grow and develop. Testosterone is made by the testicles.
