What is the Penis?
- external structure
- Conveys urine from the bladder and semen from the reproductive structures to the outside.
What is the prostate gland?
- A gland surrounding the urethra just below the bladder
- Produces additional fluid that combines with sperm to form semen, and helps to increase sperm motility and longevity, supporting the sperm’s journey towards the egg
What is the seminal Vesicle?
- located behind the bladder and above the prostate gland
- Produces a sugar-rich fluid that provides energy to sperm. (70% of semen)
What is the Scrotum?

What is the Testicles?

- enclosed within the scrotum
What is the Urethra?
Conveys urine from the bladder and semen from the reproductive structures to the outside.
What is the Vas deferens (sperm duct)?

What is the cervix?
Allow flow of menstrual blood from the uterus and directs semen into the uterus.
What is the endometrium?
