The microchip method is particularly recommended in cases of male-factor subfertility involving low motility or elevated sperm DNA fragmentation. By replicating natural micro-channels of the female reproductive tract, it gently isolates undamaged spermatozoa with high genetic integrity without centrifugal stress, thereby improving fertilization and blastocyst quality.

PGD/PGT is strongly advised for couples carrying hereditary genetic mutations (such as Thalassemia or Sickle Cell Anemia), advanced maternal age, unexplained recurrent miscarriages, or multiple implantation failures. It ensures that only chromosomally and genetically healthy embryos are selected for transfer.

The optimal biological window for oocyte cryopreservation is typically prior to age 35, when ovarian reserve and oocyte quality are robust. However, it can be performed for any woman seeking to preserve fertility before postponing childbearing or undergoing gonadotoxic treatments.
