Link between IVF pregnancy and difficult birth?

[WhoUpsetTheEquilibrium]

I’ve never said this out loud because I always felt like it was a bit insulting to those with babies made with the help of IVF. However in my experience, every person I know who has had an IVF baby has endured a difficult birth some ending in EMCS.
I was talking to my friend who is a SCBU nurse and she said she thought the same, in her experience IVF babies don’t tend to have smooth births.

Of course, we are just two people in a world of millions of people here to the thank of IVF and we know absolutely nothing about them and we could be totally wrong!

I just wondered what people here thought, and their experience with themselves or people they know who had IVF treatment.

After I lost my baby my ivf clinic thought that the placental failure was most likely due to poor implantation. I did some tests which showed I have a blood clotting disorder, a relatively common one which possibly increases the risk of pregnancy loss (although not the cause of our infertility).
I had treatment for this along with close monitoring during my next pregnancy and although I had an early birth, my baby was a healthy size.

Actually my IVF pregnancy was better than my natural pregnancy.
My births were about the same babies almost same size, 1oz between them, both did equal damage.

My first natural was a Labour slow to get going but once it was going went fast from tranition to baby was about 30mins sat in a pool with gas n air. The second IVF induced with pessary was intense and not sure when i hit transition but from lying down in a bath to getting out baby took 15mins.

I think most of it will be due to pre existing factors, just a few I can think of of is that the population is more likely to be:

Older
Have pre existing issues related to conception/carrying
More multiples

Etc etc.

I’m not even sure how you’d control for all those factors to pick out what if any effect ONLY the IVF has.

I think there is an increased risk of placenta praevia with ivf babies. I had this with DS (ICSI). Obviously this means a section.
