The prostate gland (the prostate) is an organ of the male reproductive system. It is about the size of a walnut and is found at the base of the bladder. The thin tube that allows urine and semen to pass out of the penis (the urethra) runs through the prostate gland. Alkaline fluid produced by the prostate gland helps to nourish sperm and leaves the urethra as ejaculate (semen). The prostate undergoes two main growth spurts. The first is fuelled by the sex hormones made by the testes during puberty. This prompts the prostate to reach an average weight of 20 grams. The second growth spurt begins when men are in their thirties.
Around 25 per cent of men aged 55 years and over have a prostate condition. This increases to 50 per cent by the age of 70 years. Early stages of prostate disease may have no symptoms.
If you are a man and you are in your 50s or 60s, talk to your doctor about whether you need to have your prostate gland checked and, if so, how often. If you have a family history of prostate disease (or if you have particular concerns), talk to your doctor earlier about when prostate checks might be suitable for you.
