If not what is the criteria?

For example with the information below what would/would not be tested on day 5?

Thanks for your help.

You bring up many good questions regarding pre-genetic diagnosis (PGD) of embryos. I have answered your questions below largely in order.

We only perform genetic screening or diagnosis on embryos that are still viable. The arrested embryos (those that have stopped dividing) are not tested.

We don’t have an absolute criteria, but in general we only screen embryos that are dividing. Typically they have over 60 cells when we perform the pre-genetic screening (PGS) testing.

We perform PGS predominantly only on blastocysts (those embryos that have a blastocoele cavity). We do not do PGS on morulas in our center. In terms of Grading, we do not restrict our PGS to certain grade embryos so long as they are dividing and are not arrested. Typically embryos that are screened with PGS have greater than 60 to 100 cells at this stage of development.

Thank you for your interest in HRC Fertility. I would love to speak to you more about the precise role/indications for PGS and how it may benefit you. Please reach out to my team to schedule an appointment in our new Inland Empire office (909.941.1120)or if not convenient at our Pasadena office (626.440.9161). I look forward to speaking with you!

Dr. John Norian
