    Testicles FAQ

    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. After puberty is finished, the testicles will produce millions of sperm a day.

    But it's easy to make mistakes in your quest for muscle. Here's how to avoid those errors.

    Do These 5 Things Now

    Following these steps will help you give your muscles the exercise and the fuel they need to get bigger.

    1. Get a checkup. If you’re new to exercise or you have any health issues -- especially heart problems or conditions that affect your muscles or joints -- get a physical exam by your doctor or other health care provider before you start a muscle-building program.

    2. Skip the shortcuts. As you’re starting on your path to bigger muscles, focus on the basics, says Shawn Arent, PhD, a certified strength and conditioning specialist and associate professor at Rutgers University in New Jersey. Spend your energy working out and eating right -- not chasing fancy supplements. And don’t even think about using steroids, he says. They can do serious damage to your body now and in the long run.You don't need steroids to build better muscles. During puberty, your body naturally pumps out testosterone. This hormone encourages your muscles to grow, says William Roberts, MD, a professor of family medicine and a youth fitness expert at the University of Minnesota.

    3. Build a solid program. When you're starting out, avoid tossing together bits and pieces of different weight-lifting programs you see in magazines, Arent says. Instead, build a basic core program that includes the bench press (for your chest), squats (legs), deadlift (legs and back), and shoulder press (shoulders and upper back). As you master these, or you start playing a sport that requires specific strengths, you can add more complex lifts.
