Question: Infant testical Size

 rsamanthif - Sun Aug 12, 2007 4:58 am

I have a 8 months old son and his left testical is a bit bigger that the other one. Could there be a problem. What should I do.

User avatar Hi Rsamanthif,

Testicle size in infants is typically about the size of a small marble, perhaps about one centimeter in size.

It is also common for one testis to be bigger than the other. However, the difference should not be large.

If your son has larger testes than this or if the left is significantly larger I would recommend he see his pediatrician.

Best wishes.
