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:
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.
