Hi Lozenge,

I have used both IVFA and SIVF.

My Dr at IVF Australia was Prof Illingworth he is great. We fell pregnant with IVF Australia in 2006 after one stimulated cycle (two embryos in the end) - fresh cycle didn't work but frozen worked and we had a beautiful baby boy in 2007.

So when it was time to go back for baby #2 we had no hesitation in going back to IVFA.
Last year we did two stimulated cycles with IVFA with no luck - first cycle we only got one embryo, second cycle two - did accupuncture with this cycle

Disappointed, I started to do some more research and got some advice from my accupuncturist. I have PCOS and it seems my estrogen levels can spike very quickly at the end of my stimulated cycle. The problem with IVFA is that they only do egg collection on Monday, Wednesday & Fridays, so for me in the cycles from last year they went too early on the first one and too late on the second cycle.

So we switched to SIVF in December and see Dr Lok who is also great. The greatest benefit of SIVF for me is that they collect 7 days a week, and therefore organise egg collection on a day that is optimal for me, unlike with IVFA where I had to fit in with their schedule.
Also SIVF apparently have a more advanced and better freezing technique than IVFA - therefore greater success rate with frozen embryo transfers.

We find out tomorrow our final number of embryo's (at day 3 we had our best number yet!) and are scheduled to have our transfer.

In terms of costs between the two they are now about the same following the recent changes to the medicare rebate.

There is another option Westmead IVF - Dr Lok also works at that clinic, I believe they now collect 7 days a week and are significantly cheaper. For financial reasons only ,this is where we might be heading next if we have no luck at SIVF.

Best of Luck, let us know what you decide
