Preimplantation Examination

What is preimplantation examination?

The basic prerequisite for the preimplantation examination is for the partner couple to participate in the IVF program. The IVF program allows us to investigate embryos before transferring them to the cervix. The examination is usually done in the blastocyst stage (100-cell embryo) by taking 3-5 cells from the embryo to develop outside the female body.
By examining 5-day embryo cells, disorders of both maternal and paternal origin are revealed, as well as newly occurring changes that happen only after egg inoculation due to errors in early divisions of early embryo cells. After the biopsy, embryos are frozen and, in the case of normal results, are thawed and transferred. There are two basic types of preimplantation examination:

PGS (Preimplantation Genetic Screening)

PGD (Preimplantation Genetic Diagnostics)
