Male Reproductive System By: Jesse Kahanofsky & Chandler Batty
Interesting facts • There are two types of penises. One kind expands and lengthens when becoming erect (a grower). The other appears big most of the time, but doesn't get much bigger after achieving erection (a shower). • Smoking can shorten your penis by as much as a centimeter. Erections are all about good blood flow, and lighting up calcifies blood vessels, stifling erectile circulation. So even if you don't care all that much about your lungs or dying young, spare the ill guy. • An enlarged prostate gland can cause both erectile dysfunction and premature ejaculation. If you have an unexplained case of either, your doctor's looking forward to checking your prostate. Even if you're not.
Major organs and function • Penis • Scrotum • Testes • Epididymis • Fertilizing the egg is the main function.
