Can third-generation IVF be performed for individuals with abnormal Y chromosome duplication?

Chromosomal abnormalities involving the Y chromosome can be addressed with third-generation IVF. Third-generation in vitro fertilization, also known as preimplantation genetic diagnosis (PGD), is a technique that performs molecular genetic testing for inherited disorders at the gamete or embryo stage. It involves selecting embryos without disease phenotypes for uterine implantation, thereby preventing pregnancies affected by genetic disorders. By diagnosing and implanting embryos before pregnancy begins, this method achieves eugenics from the very outset of conception, effectively avoiding selective abortion and the associated ethical dilemmas. Patients are advised to maintain regular daily routines and follow a light, balanced diet.
