Scrotum, Penis, & Spermatic Cords
MT: Male Reproductive System

4. 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

5. 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

7. 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

8. 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

10. Structure of Spermatic Cords
White fibrous tissue that surrounds the vas deferens, blood vessels, and nerves

11. Function of Spermatic Cords
Protects vas deferens, blood vessels, and nerves going into testes.
