The effect of endometriosis on pregnancy outcome following in vitro fertilization-embryo transfer (IVF-ET) in women with decreased egg reserve. 
To determine the effect of the presence of endometriosis on the delivered pregnancy rate following in vitro fertilization-embryo transfer.  A retrospective cohort analysis of fresh or frozen embryo transfer in women with diminished egg reserve having IVF-ET and who also had had a laparoscopy.  The data was analyzed as to whether endometriosis was present or not.  The data demonstrated that women with diminished egg reserve can achieve pregnancies following IVF-ET.  The presence of endometriosis did not have any negative effects on pregnancy rates.  At least in women with diminished egg reserve the presence of endometriosis did not impair outcome following IVF-ET.
