Hi dr,my two months old son's testicles seems uneven in size. it is normal?

Here are some ...: What you see in your son's scrotum (probably not testicles) may represent a possible communicating hydrocele, which fluctuates in its size (fullness) - more in the afternoon or evening and worse in the morning. But without a look at & palpation on it, it's hard to come up an accurate Dx. So, bring him to see urologist for analyzing Hx, physical findings, and possible tests so to confirm what it's.

Please Don't Worry: Maybe,maybe not.Depends what it looks like,but based on what you said it could be anything from a normal variant to a hernia to a hydrocele to a missing ("undescended') testicle.Nothing that requires an emergency look(unless he's screaming or super cranky or can't pee)but should be evaluated sooner than later. If a normal variant there's a way to check:you know what they say: Like father, like son
