Just found your thread - are you still considering VR?
My partner recently had a VR 12 years after his initial vasectomy. We went to Duncan Harriss, he was wonderful. It's still early days yet, so we don't know the results... but fingers crossed.
He did see his GP, but he was useless, just wrote a referral (which we didn't need) and gave him the same statistics that we had found online.
We decided to go for VR rather than IVF straight away because I really wanted the opportunity to try like a normal couple, and if it worked it would give us the option to try for a second 'for free'! A few months on from the VR, and the relief of feeling like we could be normal is lovely. I know I might be kidding myself, won't know until he has his SA, but for now, normal is nice
