title: [Biological process in patients having been impregnated through GIFT or IVF-ET. Clinical experience].
abstract: There were analyzed in a retrospective way the results of pre-retrieval hormonal levels as well as the number of retrieved oocytes, mature oocytes and transferred embryos in three groups of patients (2 GIFT, 1 IVF-ET) which achieved a pregnancy, and were matched with groups with no pregnancy. There were no statistically significant differences in most of the analyzed parameters, by the aforementioned we can suppose that pregnancy depends of endometrial quality and in this moment we are not able to modify it satisfactorily.
