Because the prostate surrounds the urethra, any disease of the gland
is likely to cause disturbances in urinary flow, and in the frequency and efficiency with which the bladder is emptied. There are three common diseases that may affect the prostate, and consequently urinary flow and frequency of urination:
How semen is made and ejaculated
- BPH, which results in frequent urination and a reduced urinary stream, and affects almost 50% of men beyond middle age
- Prostate cancer, which is now the most common malignancy in men with a 1 in 14 lifetime risk, rising to 1 in 11 for men over 50 years of age
- Prostatitis, an inflammatory disease affecting about 1 in 15 mainly younger and middle-aged men, which is characterized by symptoms of pain and discomfort around the anus, scrotum and the area in between (the perineum).
