Due to the rapid growth and advancement of PGS techniques, PGS is not yet recommended by major professional societies. That said, it is clear that the field of ART is changing, and changing in a way that favors use of these novel technologies. The American Society for Reproductive Medicine recommends no more than two embryos be implanted in women under 35—and doctors should consider using just one. The U.S. may be moving toward a single embryo transfer during IVF, similar to Europe, making the use of PGS technologies such as NGS even more important to increase the odds of a successful pregnancy.
