Part 7/8:
Over time, fertility treatment practices have evolved. Dr. Crawford points out that modern approaches focus on transferring fewer embryos during IVF or ovulation induction cycles. She advises targeting a maximum of one or two embryos, as advancements in genetic testing allow for more precise selection of viable embryos for transfer.
The shift in practice is also influenced by the realization that the risks associated with multiple pregnancies often far outweigh any short-term benefits. While patients may voice concerns over costs associated with fertility treatments, Dr. Crawford emphasizes that raising twins is significantly more expensive in the long run.
