Testicles, also called testes or balls, are oval-shaped organs that sit in a sac that hangs behind the penis.
The main job of testicles is to make and store sperm and produce testosterone. Testosterone is the male hormone that's responsible for the changes that occur during puberty. Puberty is the time in life when your body begins to change and you start to look more and more like an adult.

I have pimples. What should I do?
Pimples begin when the pores in your skin get clogged with a type of oil called sebum.
Some sebum is important to keep your hair and skin from drying out. But hormone changes can cause your body to make too much of it.
Here are steps to get rid of pimples -- and keep new ones from forming:
Wash your face twice a day with a gel-based or foaming cleanser.
Avoid harsh soaps and products containing alcohol.
When washing your face, gently massage it with circular motions.
When you have finished washing, use a lotion with the acne medicine benzoyl peroxide. You can get these in the drug store or supermarket without a prescription.
If zits are interfering with your life or if they don't improve with your daily cleansing routine, you may want to see a dermatologist (a doctor who specializes in skin conditions) to prescribe a stronger medicine. There are also many things you can do on your own to help.
Don't pop pimples. Popping pimples can make them look worse and may cause them to leave a scar.
Keep your hair off your face, neck, or other pimple-prone areas. Oil and dirt from your hair can block pores. If you want to wear your hair longer, make sure you keep it clean.
Don't touch your face. This can spread bacteria that irritate pores.
If you wear glasses, keep them clean. Cleaning them can help keep the oil on them from blocking the pores where they touch your face.
If you follow these steps, you'll also help keep your face from getting greasy. Greasy skin can lead to pimples.
