When undergoing ovarian stimulation, follicles do not all grow at the same rate, some mature faster than others which means that the eggs they contain are also in different states of maturation. Mature eggs, M2, fertilize very well, usually higher than 70%. Immature eggs, those at the GV stage, will not fertilize when inseminated.

Intermediate eggs, those that are at the metaphase I (M1) stage will sometimes fertilize when inseminated by either conventional insemination or ICSI but they fertilize better when we wait for them to mature before doing the insemination.
