I'm 42 this month, and about to do my next IVF

With my first IVF, I wasn't informed of the risks of assisted hatching.I now understand that the risk for identical twins seems higher, but don't know what percentage of risk this would be

I also don't know how this compares to the chances of my 42 year old eggs not hatching if left to their own devices.

This info would be helpful to make an informed decision.

My last IVF was done at a different clinic, with AH. Would most embryologists have notes on how tough the zona was, to know if AH was really needed? Should I ask this clinic to contact their embryology dept?

Any help with this decision would be appreciated. I am concerned about twins, but much more so identical twins as I understand these pregnancies can be more complicated.

Lastly, I understand that daily updates on embryo status is not routinely provided at my current clinic. This makes me very nervous. Is it reasonable to request this if it isn't the normal standard of care?

Thanks,

A.N.

The incidence of identical twins associated with AH is extremely low in fact very little data are available

I also don't know how this compares to the chances of my 42 year old eggs not hatching if left to their own devices.

This depends on your past history

This may be recorded in your notes

Should I ask this clinic to contact their embryology dept?

It might be helpful

Not necessarily, it's just twin pregnancies of any description which carry slightly higher risks

Lastly, I understand that daily updates on embryo status is not routinely provided at my current clinic. This makes me very nervous. Is it reasonable to request this if it isn't the normal standard of care?

You need to ask your clinic about this if it is important to you. In general terms most embryologists are more than happy to talk about the embryos in their care.

Good luck!

Peter

Hi Peter,

Thanks for your response!
I met with my RE today. Turns out that they don't believe in Assisted Hatching so looks like I was concerned for nothing...But I was able to get assurances that they can let me know about my embryos daily. Thanks so much for letting me know that seemed reasonable.

It would be great if you could use Italics to distinguish your response from the questions
