Specifically, the gold standard technique, Preimplantation Genetic Testing for Aneuploidy (PGT-A), combined with In Vitro Fertilization (IVF), offers a near 100% accuracy in determining the sex of an embryo before transfer. Therefore, we confirm the technical possibility is virtually guaranteed. Conversely, older or less reliable methods like sperm sorting (e.g., MicroSort) have significantly lower accuracy, ranging from 70% to 90%, and are rarely used today.
