Question: differences in son's testicular mass

 his mom - Sun Aug 19, 2007 1:37 am

My 20 yo old son overcame great embarrassment to share his concern about a change he's noticed in one testicle.

He had surgery on the left testicle at 18 months old (undescended) and has had no problems since. He very recently became sexually active.

He states that his right testicle always feels firm and full (normal), but that the left is sometimes normal and sometimes "flat", in his words. He is worried that the lack of fullness signifies a medical problem, but is embarrassed to speak to our PCP.

What could cause a single testicle to have what appears to be changing volume/mass/firmness?

User avatar Because you mention this is changing for him, it would be wise to see a urologist or even a family practice physician. But, as a rule, a difference in testicle size and shape would not be a cause for concern. Even if one testicle was not functioning, a man only needs one to produce sperm and make him fertile.
