The External Male Genitalia Are the Penis and Scrotum
Circumcision is an ancient practice that is
religiously prescribed for Muslims and
Jews.
There is some controversy over whether
circumcision of male infants should be
recommended or discouraged.

The External Male Genitalia Are the Penis and Scrotum
The shaft of the penis contains three erectile
structures: a pair of corpora cavernosa and
one corpus spongiosum.
The corpus spongiosum extends from the
shaft and expands to fill the glans of the
penis.
The urethra runs through the penis close to
the underside. It discharges urine and
semen.

External Male Genitalia:
Penis and
Scrotum (cont’d)
The ischiocavernosus and bulbospongiosus
muscles assist with erection and ejaculation.
They retard blood flow out of penis or clitoris.
They also help hold the penis erect or tense the
vagina.
Kegel exercises help strengthen them.
