This research study is looking at embryos with many abnormal chromosomes, called "complex aneuploid" (three or more) or "chaotic" (six or more). Aneuploidy means having the wrong number of chromosomes, which can affect development. *Preimplantation Genetic Testing for Aneuploidy (PGT-A)* is a test used to check the chromosomes of embryos before they are transferred to the womb. The study will re-test embryos that initially showed many chromosomal problems to see if they could actually be normal. This could help decide if these embryos might still be used for pregnancy.
Key Information:
- This study involves re-testing embryos, not transferring them.
- Your choice to participate will not affect your medical care.
- Participation is completely voluntary and appreciated.
The study wants to find out if some embryos with chromosomal issues can be normal after a second test. If you have an embryo with abnormal chromosomes and agree to participate, your embryo will be re-tested. This re-testing might show that the embryo is normal, which could increase the chances of a healthy pregnancy in the future.
