_____________________.
Spermatic Cord - Answer Contains vas deferens, pampiniform plexus, and external cremaster
muscle nerves
Vas Deferens - Answer Transport sperm during ejaculation
Seminiferous Tubule - Answer Sperm producing cells- true germinal epithelium
Testes - Answer In which part of the male reproduction system is functionality key?
Corpus Epididymis - Answer Where does the maturation of spermatozoa occur?
Cauda Epididymis - Answer Where does the final maturation and storage of sperm take place?
Only sperm capable of fertilization
Tunica Albuginea - Answer Connective tissue which holds testis together
Caput Epididymis - Answer Function in maturation of spermatozoa, fluid absorption
Sertoli Cells - Answer What are the cells that support spermatogenesis?
Leydig Cells - Answer Cells that synthesize testosterone
, 1) Produce sperm (spermatogenesis)
2) Transport sperm out of the testes
3) Produce testosterone - Answer What are the 3 main functions of the testes?

surface area) that helps with counter-current heat exchange to cool arterial blood supply.
Counter-current - Answer __________________-________________ heat exchange causes a
cooling of arterial blood supply.
Cryptorchidism - Answer Lack of testis descent into scrotum and thus thermoregulation is
absent
Bilateral - Answer Sterile, no spermatogenesis, testosterone produced
Unilateral - Answer Fertile, reduce sperm producing capacity
