More blastocysts are produced from fewer oocytes in ICSI compared to IVF – results from a sibling oocytes study and definition of a new key performance indicator
Abstract Background Which fertilization method, between ICSI and IVF in split insemination treatments, has the highest clinical efficiency in producing clinically usable blastocyst? Methods 211 infertile couples underwent split insemination treatments for a non-severe male factor. 1300 metaphase II...
