What is a significant factor in the success of in vitro fertilization (IVF)?

A significant factor in the success of in vitro fertilization (IVF) is the health of the embryos created. The development of healthy embryos is crucial because they need to have the proper genetic and physiological characteristics to implant successfully in the uterine lining and develop into a viable pregnancy. Factors influencing embryo health include the quality of the eggs and sperm used in the fertilization process and the conditions in which fertilization and subsequent embryo culture occur.

Healthy embryos are more likely to divide correctly and possess the genetic integrity necessary for a successful outcome, which is why embryonic health is a critical consideration in IVF protocols. Ensuring a high-quality selection of embryos can significantly improve the chances of a successful implantation and pregnancy. Thus, evaluating and selecting the healthiest embryos for transfer is one of the key steps in maximizing the success rate of IVF treatments.
