Harry had an undescended testicle at birth which was repaired at age 3 under the guise of a hernia operation. The true cause of the surgery came out yrs later. The result is a low sperm count so this is not a rumor. Do a search and you can find articles about it. That of course does not preclude having children. But combined with the very low fertility of the typical 37 yr old it is pretty surprising she managed it so quickly.
