Q | what is benign prostatic hypertrophy (BPH)?
A | This is part of the normal ageing process in men where the prostate gland increases in size. The prostate grows to its normal size around the time of puberty, however, it then starts to slowly increase in size in the third decade and onwards.
As the prostate gland is somewhat contained by its outer layers, an enlargement of the prostate tends to impinge upon the urethra, narrowing the channel for urine in the process.
This can lead to some of the symptoms of BPH. Around 10% of men in their 40's have BPH and this figure rises to 50% of men in their 50's and 90% of men over the age of eighty.
