Structure of the Scrotum
• Skin-covered pouch where pubic hair grows
• Divided into two sacs by a septum
• Each sac contains a testis, epididymis and a lower part of a spermatic cord
• Has a muscle in it that contracts to contract or relax the testes

Function of the Scrotum
– Ideal temperature for testis to make sperm is 3 degrees below body temperature
– Scrotum must adjust• Cold person – scrotum contracts; testes close
to body • Hot person – scrotum relaxes; testes away
from body

Structure of Penis
• Made of 3 cylindrical masses of erectile tissue, held together by skin
• End of penis is slightly bulging called the glans penis
• Glans penis is covered by a loose skin called prepuce (foreskin)
• Circumcision – surgical removal of prepuce

Function of Penis
• When stimulated, erectile tissues of penis fill with blood, creating an erection.
• Erection permits the penis to serve as a penetrating device to release semen
