BACKGROUND: This study evaluated the characteristics and results of @entity1 who suffer from @entity177 ( @entity177 ). MATERIALS AND METHODS: In this cross sectional study, a total of 2183 cases who were evaluated retrospectively at the Istanbul University Cerrahpasa Medical Faculty, Department of Obstetrics and Gyneacology, IVF unit between 2000-2007. According to the data gathered, we included 1822 cases in this study. We compared 185 @entity1 with @entity177 to 1637 @entity1 without @entity177 . RESULTS: Pregnancy was achieved by 589 couples out of 1822 (32%). The implantation rate was 10%, which declined to 5.8% after the fourth attempt. In the @entity177 group, @entity1 ' mean age was higher and there were more overweight @entity1 , the duration of fertility was longer, day 3 follicle stimulation hormone (FSH) levels and the total @entity4083 dose administered were higher, mean level of @entity53 (E2) on the @entity1 chorionic gonadotropin (hCG) day was lower, and the mean level of @entity1420 on the hCG day was elevated compared to the non- @entity177 group. Although the comparison of MII oocyte number was not significant, the mean number of fertilized oocytes was found to be significant in favor of the non- @entity177 group. The endometrial thicknesses were found to be similar for both groups. Comparison of sperm motility and morphology were statistically significant in favor of the @entity177 group. CONCLUSION: In our study, we have found that the group with @entity177 were comprised of @entity1 with poor prognosis who were older, overweight, had a longer @entity249 duration, a higher FSH level, and needed more gonadotropin doses in @entity43 ( @entity43 ). Sperm motility and morphology were better in the @entity177 group compared to the non- @entity177 group, and multiple pregnancy rates were lower in @entity177 @entity1 .

Recurrent implantation failure is more frequently seen in female XXXX with poor prognosis.
