Penis

The penis is a male reproductive organ that serves two main functions: urination and sexual intercourse. There are several medical and surgical conditions that can affect the penis, including:

1. Erectile dysfunction: This is a condition where a man has difficulty achieving or maintaining an erection sufficient for sexual intercourse. It can be caused by a variety of factors, including age, chronic health conditions, or lifestyle factors. See our penile rehabilitation information to recover erections after radical prostatectomy.

2. Peyronie's disease: This is a condition where scar tissue forms within the penis, causing a curvature or deformity of the erect penis. It can cause pain and difficulty with sexual intercourse.

3. Phimosis: This is a condition where the foreskin cannot be retracted from the head of the penis, causing difficulty with hygiene and sexual intercourse.

4. Priapism: This is a condition where the penis remains erect for an extended period of time, usually more than four hours. It can be a medical emergency and requires immediate treatment.

5. Balanitis: This is a condition where the head of the penis becomes inflamed, causing redness, swelling, and discomfort.

6. Penile cancer: This is a rare form of cancer that can affect the skin or tissue of the penis. It may present as a lump, sore, or growth on the penis.
