Varicocele??

Sh
Hi Ladies, 
My hubby is devastated. Just found out he has Varicocele. The doctor told him it was very common and not to worry about it as it is treatable with surgery. His insurance will cover around 50% of the surgery costs. I'm thinking we are going to have it done, wait a year while TTC and if nothing happens then go with IVF. After the doctor looked over my blood tests he said I'd have a 50-60% chance with IVF since I already have 2 children and am only 31. 
Has anyone dealt with this before? Any advice?!?!?
Thank you ladies 😒
