2. Testes –
produce male sex cell –
produce male sex hormone –

coiled structure that stores and matures sperm (sperm “bootcamp”)

9. Parts of the Male Reproductive System
4. Vas Deferens –
5. Seminal Vesicle –
6. Prostate Gland –
7. Bulbourethral Gland –
          
connects the epididymis to the urethra (sperm “superhighway”)
secretes fluid that mixes with the sperm to make semen
produces more fluids for semen
produces more fluid to
protect semen from acid
in urethra

10. Male Reproductive Organs

11. Parts of the Male Reproductive System

FUN FACTS!
A male usually ejaculates about 2–5mL of semen; each milliliter containing about 50 – 130 million sperm.
Bulbourethral fluid also carries some sperm released before ejaculation.
This is one of the reasons why the withdrawal method of birth control has a high failure rate.
