My son is 9 mos old. His left testicle is and has always been non-palpable. His right testicle was descended at birth, but has started to ascend for the past couple of months; it however, is still palpable, being felt when milking it down toward the scrotum. We will be consulting with a pediatric urologist. It may be a while before he gets us in, as he is the only one in the state. I understand that sometimes testicles for one reason or another, don't descend, but am concerned as to why the right testicle is traveling back up.
