contains nutrients for the sperm
6Parts of the Male Reproductive System
- Seminal Vesicles
- - Glands that produce the fluid (semen)
- to carry the sperm out of the males body
7Parts of the Male Reproductive System

- - This is where the sperm cells and the male
hormone, TESTOTERONE, are produced - - The testes are located in the scrotum
- - Produce Testosterone which triggers puberty
8Parts of the Male Reproductive System

- - The pouch or sac of skin which contains the
testicles - - Keep temperature in the testes is 6 degrees
below body temperature, the best temperature for
producing sperm -
9Parts of the Male Reproductive System
- Epididymus

10Parts of the Male Reproductive System
- Sperm
- - The male sex cells which are capable of
- fertilizing and egg
- - 400 million could fit on the head of a pin
- - Testicles can produce more than 200
- million or more sperm cells a day
