Like Arlais, we had a VR done (Sydney in December 2012 - 15 years post vasectomy), but after 10 months of TTC naturally, DH still had v low sperm count and motility, and we were worried that the odds of conceiving naturally were stacked very much against us. After seeing a female fertility specialist at IVF Australia we decided to go down the ICSI route, as neither of us were getting any younger and really didn't want to wait much longer.
I haven't been on this thread for a very long time as TTC naturally was such an emotional experience for me (so I feel for you 100% ) but I am pleased so say that we conceived our beautiful DD on our first round of ICSI. She was born in July 2013 and is now 11 months old.
I was soooo worried that they would have to do a sperm retrieval on DH when I had my eggs collected as they "forgot" to freeze any sperm during the VR, but we were able to conceive her using the very few sperm DH had in his ejaculate. We also have 3 frozen embryos to use in future so it was well worth it.
From memory, our out of pocket IVF expenses (after Medicare and HCF rebates) were around the $4000 mark. We did have to pay about $8000 upfront, but you get a big chunk back within the month.
All the best for your journey - I really hope you have a BFP very soon.
