Looking for Insight With Varicocele

Hi! My husband and I have been TTC for 15 months and recently identified a stage three, left Varicocele. It took nearly two months to get in with a highly-regarded Urologist with an expertise in male fertility.

If anyone has feedback on what to expect from the procedure, conception success or failure after, etc. it would be greatly appreciated! He had low count in two SAs (around 4 million), above average motility, and 2% morphology 😔
