| The catheter seen here is in a groove on the undersurface below the tip of the penis and enters the urethra. This abnormal opening is known as a hypospadias. Such an anomaly is not common but can lead to problems with urination and ejaculation. Some congenital and acquired conditions involving the penis are listed below: |
| ABNORMALITY | DESCRIPTION |
|---|---|
| Hypospadias | Urethral opening below tip of penis on ventral surface |
| Epispadias | Urethral opening above tip of penis on dorsal surface |
| Phimosis | Inability to retract the foreskin of uncircumcised penis because of scarring with adhesions |
| Paraphimosis | Forcible retraction of foreskin with phimosis leads to painful swelling that can obstruct the urethra |
