Why are eggs fertilized by IVF destroyed?

Fertilized eggs created through in vitro fertilization (IVF) are often destroyed for several reasons. Some embryos may not meet the required quality for implantation, while others may be leftover from the IVF process and not used due to ethical considerations or patient decisions. Additionally, embryos may be discarded if they are found to have genetic abnormalities. Ultimately, the decision to destroy fertilized eggs is influenced by medical, ethical, and personal factors.
