  1. 1. What is this bean-shaped sac outlined in blue?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the testis!

    The testis is the male gonad (sex organ) held inside the scrotum, and it produces sperm and the hormone testosterone.

  2. 2. What is this long, winding blue tube?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the Vas Deferens!

    The vas deferens, also known as the ductus deferens, is a coiled tube that carries the sperm from the testes during ejaculation.

  3. 3. What about this peach-shaped thing?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the prostate gland!

    The prostate gland sits right below the bladder and surrounds the urethra, which carries urine out of the body. It produces seminal fluid, which helps to nourish and transport sperm as it leaves the body through ejaculation.

  4. 4. What is this tube called?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the urethra!

    The urethra carries urine from the bladder to the outside of the body. It also carries semen from the ejaculatory duct when muscles around the base of the penis contract to force it out of the body during ejaculation.

  5. 5. OK, so what do you call this entire hanging structure?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the penis!

    Yup, this is just the actual penis! It's the external part of the male reproductive organ and contains the urethra, which carries urine and semen outside the body.

  6. 6. Can you name this lumpy, red sac?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the seminal vesicle!

    The seminal vesicle is a pair of glands that open into the vas deferens and secrete some of the fluid that makes up semen. This fluid contains enzymes, protein, fructose, and vitamins to support the sperm. The fluid also has an alkaline pH to help neutralize the acidic environment of the vagina.

  7. 7. What is this opening called?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the anus!

    The anus is the opening of the rectum, where feces can exit. It’s also the point of entry for anal insertion and prostate stimulation.

  8. 8. What is this big, hollow red thing?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the bladder!

    The bladder is a hollow sac that collects and holds urine until it's released during urination through the urethra, which goes through the penis.

  9. 9. What about this short section of tube that connects to the blue and red things?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the ejaculatory duct!

    The ejaculatory duct passes through the prostate and empties semen that contains sperm and fluid from the vas deferens and seminal vesicle into the urethra during ejaculation.

  10. 10. What about this tiny pea-shaped thing hanging by a thread?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the Cowper's gland!

    The Cowper's glands, also called the ulbourethral glands, are small and sit under the prostate. They add fluids to semen full of proteins and natural lubricants that help to wash out the urethra of acidic urine before semen enters for ejaculation. They produce pre-ejaculate!

  11. 11. What is this little blue thing that looks like the head of a jellyfish?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the epididymis!

    The epididymis (say that three times fast!) is a curved tube on the back of the testis. It stores newly made sperm for about a week so it can mature to a point where it's able to fertilize an egg, at which point it passes through the tail of the epididymis into the vas deferens.

  12. 12. OK, so what are these little tentacle-looking things down here?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    These are the efferent ductules!

    These are a group of 15–20 ducts that serve as a pathway for sperm between the testes and the epididymis. They help to reabsorb water from the luminal fluid (which carries sperm) to increase the concentration of sperm during ejaculation.

  13. 13. What is the network of squiggly things inside the testis?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    These are the seminiferous tubules!

    The seminiferous tubules make up most of the testes. They are the actual site for the meiosis of cells into gametes, or the creation of sperm cells for sexual reproduction. These mature in the epididymis before they can fertilize an egg or ovum.

  14. 14. What are these long yellow tubes?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the ureter!

    The ureter carries urine from the kidneys to the bladder, where it's held before urination.

  15. 15. What do you call the ending of this hollow cavity?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the rectum!

    The rectum is the last several inches of the large intestine before the anus. It serves to pass feces through the body and it contains muscle.

  16. 16. What about this spongy-looking structure?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the pubic bone!

    The pubic bone is connected to the pelvis and helps make up the male pelvic floor and give it structure.

  17. 17. What is the striped curved section of tissue inside the penis?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the corpus cavernosum!

    The corpus cavernosa are two cylindrical bodies of tissue inside the entire length of the penis. They are spongy so when the nerve response of sexual arousal sends blood to the penis, the corpus cavernosa fills with blood. The sudden increase in blood volume causes stiffening and expanding of the penis, otherwise known as an erection!

  18. 18. Finally, what is the mushroom-shaped end of the entire penis structure called?

    kocakayaali / Getty Images / thinkstockphotos.com
    Correct! 
    Wrong! 

    This is the glans penis!

    This structure is the head of the penis, where the corpus cavernosum ends. It contains the opening for the urethra, where urine and semen exit the penis.
