Abstract:
Natural cycle IVF produced the world first successful live birth, but slowly this treatment has been replaced by ovarian stimulated cycle IVF, because it has been believed ovarian stimulated cycle IVF will increase the number of available embryos for transfer. Therefore, it directly increases the chance of pregnancy from the treatment cycle. However, ovarian stimulation is always associated with side effects. The recovery of immature oocytes followed by in-vitro maturation (IVM) and IVF is an attractive alternative to stimulated cycle IVF. IVM treatment provides a successful option to infertile women with polycystic ovaries and polycystic ovary syndrome. It is now possible to combine natural cycle IVF with IVM as an alternative for a selected group of women with various causes of infertility without recourse to ovarian stimulation.
