The number of embryos that can be cultured from 22 follicles depends on the quality of the follicles.
Under normal circumstances, one follicle can produce one embryo, but the phenomenon of one follicle producing two embryos cannot be ruled out, and the follicles may not produce embryos when their quality is poor. Therefore, there is no way to know how many embryos will be produced from 22 follicles.
Under normal circumstances, the number of eggs retrieved by a woman is around 8 to 15, while 22 follicles is a high number, and polycystic ovary syndrome may be present.
The number of embryos grown is also related to the quality of the follicles and the quality of the sperm, etc. Generally speaking, if the follicles are of good quality and the sperm is of good quality, the number of embryos grown will be relatively high.
