What role does genetic screening play in IVF treatments for twins?

Genetic screening, particularly Preimplantation Genetic Testing (PGT), plays a vital role in improving IVF outcomes, including twin pregnancies. PGT allows specialists to screen embryos for chromosomal abnormalities before implantation. This helps identify the healthiest embryos with the highest potential for a successful pregnancy. While PGT does not directly increase the chances of twins, it ensures that if multiple embryos are transferred, they are genetically viable, thus supporting a healthy multiple pregnancy when twins occur.
