The number of eggs taken for IVF is usually within a certain range, and there is no such thing as how many eggs are the best to take, usually 10-15 eggs are better. Generally speaking, the number of eggs retrieved has a certain impact on IVF. Too few eggs retrieved will lead to a decrease in the number of embryos, which will easily reduce the success rate of IVF. However, the number of eggs retrieved is not the more the better, so as not to cause ovarian hyperstimulation syndrome. There exists a more ideal range, for women under 40 years old with normal ovarian function, it is usually better to retrieve 10-15 eggs. It should be noted that for women with poor ovarian function and a basal follicle count of 5-6, all follicles should be retrieved as much as possible to increase the likelihood of transferring embryos.
