Male Reproductive system
Structure Function
Scrotum Pouch-like structure tht contains the - Temperature regulator: keeps testis
testis 2-3°C lower than body temperature
for for sperm formation (pulls testis
closer/furthur from abdomen based
on temperature)
- Houses and protects the testis
Testis - 2 oval structures suspended - Sperm production (by germinal
(Plural: testes) outside the body in scrotum. epithelial cells)
- In abdominal cavity below - Produce testosterone by interstitial
kidneys in embryonic stage cells
- Consist of many
compartments/lobules with
highly convuluted tubules
