Problems with the penis can cause pain and affect a man's sexual function and fertility. Penis disorders include
- Erectile dysfunction - inability to get or keep an erection
- Priapism - a painful erection that does not go away
- Peyronie's disease - bending of the penis during an erection due to a hard lump called a plaque
- Balanitis - inflammation of the skin covering the head of the penis, most often in men and boys who have not been circumcised
- Penile cancer - a rare form of cancer, highly curable when caught early
