What Increases Your Risk
Men who are older than 50 have a higher risk for benign prostatic hyperplasia (BPH).
The hormone testosterone, which is produced mainly by the testicles, is needed in order for BPH to develop. Men who have their testicles removed before puberty never develop BPH. Men who have their testicles removed after puberty (but before they have symptoms of BPH) rarely develop BPH.
A family history of BPH may increase your risk for needing treatment for this condition, especially if a relative needed treatment before age 60.
A vasectomy does not increase your risk of BPH.
