So there is probably a post like this somewhere in the archives, but I thought it would be interesting to see how many people know couples who have conceived naturally after IVF?

We all hear about it, but is it an urban myth? In my case I have the following friends or aquaintances:

Couple 1: tried for 7 years, had OHSS on first cycle so no fresh transfer-> one embie transferred-> BFP. 12mths after he was born thet DTD ONCE and she conceived naturally.

Couple 2: TTC for 7 years (I think), changed IVF centres, had a baby and conceived naturally approx 9mths later.

Couple 3: BFP on second IVF cycle, and conceived naturally at 8mths after birth of first bub.

Couple 4: At 39yo had baby 1 after IVF, then were on IVF for years with no success for number 2. Then she conceived naturally at 45!!!!

I am showing my age here, and anyone under 38 wont know what this means but "WHY is it SO?"
