The obstetric and perinatal outcomes of births from<unk>  cycles are similar to those with ICSI treatments. However,<unk>  involves the use of invasive techniques, this may harm the mother. Furthermore, embryological outcome of<unk>  is not established. A more comprehensive appraisal of health status of<unk>  children will demand larger prospective studies. The potential of cryopreserved<unk>  oocytes from cancer patients remain unknown. The optimal number of<unk>  oocytes frozen in candidates for fertility preservation (FP) is unknown. FP oocytes of infertile PCOS women have decreased competence compared to oocytes recovered after ovarian stimulation. The FP strategy of cryopreservation of oocytes after<unk>  should only be considered should ovarian stimulation is unfeasible. In norma-ovulatory women, the success rate of<unk>  is lower than conventional ovarian stimulation regimens with poorer implantation and pregnancy rates.<unk>  is suboptimal and influenced by several factors. However,<unk>  is a milder approach to assisted reproduction treatment and an alternative procedure for specific conditions. Accurate patient selection can improve<unk>  clinical outcome.
