What age do boys balls drop?

Luckily, about half of these testicles will drop on their own during the first 3 months of life. But testicles won't drop on their own after 6 months of age. Thus, about 1 or 2 out of 100 boys with undescended testicles will need treatment.

Usually around 2 or 3 months but for them to actually develop, about 6 months of age.
