The penis is the male organ used for urination and sexual intercourse. The penis is located above the scrotum. It is made 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. The foreskin is removed if the boy is circumcised. This is often done shortly after birth, but can be done later in life for various medical and religious reasons.
During puberty, the penis lengthens. The ability to ejaculate begins at around age 12 to 14. Ejaculation is the release of sperm-containing fluid from the penis during an orgasm.
