Hi hun and welcome to belly! We've been in a similar situation with success. My DF is 47 and had a vesectomy over 16 years ago after he had 3 kids with ex wife. He had the reversal done almost 4 years ago, due to me pressuring him to do it as I wanted a natural pg, but it didn't work. We were then advised to do IVF with ICSI and proceeded to do a cycle in 2008. My DF's sperm was taken out of his testie (he's only got one) and they got enough swimmers to fertilise 11 eggs and we got two 5 and 6 day embryos whish were of good quality. I've had 2 successful pg from these embryos (even though I lost my first baby to an unrelated problem). GL to you and your partner, there is success with what your action plan is!
