Varicocele surgery

My husband just had a varicocelectomy a few days ago. His urologist said it had a 2/3 success rate in terms of increasing sperm health/count etc. Curious about other women's and their SO experiences with it. How long did it take for your SO to feel back to normal? Were you able to get pregnant following the surgery? Anything else I should know? We follow up with his doctor in 5 weeks for a post-op exam and then he will have another SA in 3 months. It's the waiting that kills me tbh.
