Why do we need many eggs while undergoing IVF though I need only 1 child now?

It has been scientifically proven that the higher the number of eggs retrieved during an IVF stimulation, the higher the chances of delivering a healthy baby. Normally, not all eggs will lead to live birth. Some of the eggs may not be mature and they will not fertilize. As a woman ages, the egg quality deteriorates. Research has shown that by the age of 33, half of the eggs in a normal woman’s ovaries have a chromosomal abnormality and will cause implantation failures (embryos will not implant in the uterus) or abort early in the pregnancy. Both Chromosomal abnormalities and Genetic mutations can cause embryo arrests and implantation failures. Moreover, having additional good-quality eggs can be used to create healthy embryos & be cryopreserved for future use. This enables having more than one embryo transfer from one egg retrieval cycle and also more than one child from one egg retrieval cycle. This is both less stressful and cost-effective.
