Hi,
Is AH a common practice done on Blasts? I just recently had a Blast transfer and asked if they did AH on them, the RE told me they don't do it on Blasts because they don't need it. I have seen that some clinics do. Why the difference in practice?

My clinic wont do it either. They said it would run the risk of making the embryo too fragile prior to transfer. I guess the walls are much thinnner at blast stage than day 3 and the chemical they use to 'thin' the walls would make things bad.

As for as I know, there is more than one way to do AH. Sometimes Clinics use a chemical, drop it next to it, and it erodes (for lack of a better word) part of the zona. Other clinics use a lazer ($$$)and actually take away part of the zona. From hwat I have 'researched' the lazer is more accurate and takes a larger part of the zona, therefor possibly decreasing chances of the embryo/blast 'splitting' in utero and avioding twins.
As far as AH on blasts, my Clinic does this (using lazer). It is quite common in the bigger more successful clinics in the States but not all Clinics do it.(I scoped the internet far and wide before opting for it). I am 42 and it was my first time using AH, it was also my first bfp on fet, but I am older ('mature' -ahem)the zona may be harder on my embryos/blasts than most. (Plus I am PCO).
I hope Dr.H comes back soon so that you get a professionl's answer :)This may tide you over in the meantime

Thanks for the replies ladies, I have booked a follow up with my RE to further investigate my case. My clinic uses the lazer to AH, but only on Day 3 frozen. My RE is quite conservative and may just not feel the literature supports it.
You are right Stacy, not many of the smaller clinics in Canada do it.
I have had NO success with Blast FETs, perhaps AH is what I need to push them a little further along before the ET.

The clinics I've been to did AH on blasts, especially if you are over 35 years of age due to a hardening of the zona.
