| Definition: |
The male organ used for urination (in mammals) and copulation. It is made up of spongy tissue and blood vessels. The shaft of the penis surrounds the urethra and is connected to the pubic bone. The foreskin covers the head (glans) of the penis, and is removed during circumcision. The penis is located above the scrotum.

During puberty, the penis lengthens. Ejaculation occurs around 12 to 14 years of age.
Deformities of the penis may include:
- Peyronie's disease (there is a lateral curve during erection)
- double (during development, the penis is divided by the urethral groove)
- hypospadias
- epispadias
- palmatus or webbed (the penis is enclosed by the scrotum)
