Dear TeenHealthFX,
I feel that one testicle is bigger than the other. Is this normal?

Dear One Testicle's Bigger,


It may be normal for one testicle to be bigger than the other. However, it is important as a teenager to get this checked out by your doctor just to make sure everything is okay. Your doctor will do a testicular exam and instruct you on how to complete a monthly testicular self-exam, commonly referred to as TSE.

Many men feel uncomfortable and embarrassed about touching their bodies, but it is a very important part of your sexual health. Males around the age of 13 should begin to do TSE one time each month. This is similar to a female doing a breast self-exam to detect breast cancer.

TSE is a simple examination that you can do on your testicles to help identify what is normal and not normal for your testicles, any changes in shape or size, pain or tenderness in the area and any unusual lumps or bumps. Here is a brief description on how to do a TSE:

  1. Perform your exam after a warm shower. This will helps your testicles (scrotum area) to be relaxed and drop down.
  2. Examine each testicle using both hands. Your thumbs should be placed on the top side of your testicle and your index and middle finger should be place on the back side of testicle.
  3. Gently roll your each testicle between the thumbs and the fingers.
  4. Do this to each testicle.
  5. Visually inspect your genital area looking for any skin discoloration or bumps.

What's normal?/What not?

Your testicles should be about the size and shaped like an egg.
It is normal for your left testicle to sometimes hang lower than the right.
It should feel smooth and rubbery.
You should not feel any lumps. Pay attention and look for any small, hard pea shaped lumps.
Your testicles should not hurt or have any pain.
You should not have a feeling of heaviness in your groin area.

As said before, you should go to your doctor so that he/she can perform a testicular exam. If you have any of the symptoms above, call right away for your appointment.
