摘要
There is a general consensus on the clinical fact that the more embryos replaced the higher pregnancy rates are achieved. For this reason those IVF cycles with a low response and a reduced number of oocytes and embryos will have very few chances of producing a pregnancy. It is very important to diagnose, by means of the anamnesis and hormonal tests which patients are most likely to present a poor response to conventional ovarian stimulation protocols. It is mandatory to know the patient's plasmatic levels of FSH and estradiol together with personal data such as the age and the previous history of the patient. Only young poor responders with a normal basal hormonal profile will have some chances that by applying new protocols and combining new drugs, improve their response and have higher pregnancy rates. For the old poor responders who have already failed to alternative protocols including natural cycles, oocyte donation is the last and best hope. (C) 2000 Elsevier Science Ireland Ltd.
