Hi Michelle, I'm obviously not one of "the boys" and I don't know how to tell yo uto bring up the subject with your DH but I wanted to share my story with you...
My DH was also diagnosed with Varicocele (sp?) and we were advised to have the surgery. After some research and careful thought we decided against it.
1) DH's numbers were not great but far from hopeless
2)The docs had yet to make me ovulate so if we might need IVF anyway because of me, why should we waste the time (it takes up to a year to see results) and the money (very expensive and NOT covered by our insurance) for a surgery that has a 50% success rate.
Instead, I out DH on vitamins which did improve his overall count but could not correct the morphology or motility and we proceded with IUI's.
I got PG on my second cycle of injectible meds with IUI so obviously the surgery wasn't as necessary as the Urologist would have us believe.
My DH's count was: 8.5million / 40% motility / 4% morphology
and the count improved to 17 million with vitamins.
Good Luck

!
