The penis is the male organ used for urination and sexual
intercourse and is located above the scrotum. It is made of spongy
tissue and blood vessels.
The male reproductive structures include the
penis, the scrotum, the seminal vesicles and the prostate gland.
The shaft of the penis
is connected to the pubic bone and is made up of three separate cylinders; two paired cylinders called the corpora cavernosa
which make up the
majority of the bulk and the erectile functioning of the penis.
these cylinders actually communicate with each other for
approximately three-quarters of their length through small holes
between the cylinders and they
surround the urethra which is the channel for the flow of urine and ejaculate.
The foreskin covers the head (glans) of the penis.
During puberty, the penis lengthens and the ability to ejaculate begins
at around 12 to 14 years of age. Ejaculation is the release of
sperm-containing fluid from the penis during an orgasm.
