Document Summary

Overview: major reproductive structures, testis, vas/ductus deferens, seminal vesicle, prostate, urethra, penis. Located in scrotum: hangs outside of abdominopelvic cavity. Descent of testes: occurs during fetal development, gubernaculum shortens, thereby pulling testes into scrotum, testes in abdomen (7 month fetus, traversing the inguinal canal (8 month fetus, testes in scrotum (1 month infant) Failure to descend - 3% of males: reduced fertility, testicular cancer, doctor will wait 2 months to see if it will drop on its own. If not, they will perform surgery to lower it or remove it: can be in abdomen (18-20%) or in inguinal canal (80%) Spermatic cord: bundle of vessels, ducts, and nerves, gonadal/testicular artery, pampiniform venous plexus, vas deferens, testicular artery from aorta, venous plexus to gonadal, ivc, vas deferens carries sperm from testes to urethra, covered by cremaster muscle (skeletal mm. ) Inguinal canal: passage for spermatic cord attached to testes.
