Perinatal outcomes of patients who achieved pregnancy with a morphologically poor embryo via assisted reproductive technology

To learn more about the perinatal outcomes of conception via the use of low-grade embryos, we evaluated the relationship between the status of transferred embryos and the resultant perinatal outcomes. A total of 340 patients who achieved pregnancy via ART treatment and consequently delivered in our clinic between April 2009 and March 2014 were recruited for this study. Patients were divided into two groups according to a morphological assessment of the transferred embryos, which relegated 79 patients into a poor-embryo group with the remainders (n = 261) placed into a good-embryo group. The mean maternal age for the poor-embryo group was 36.0 years, which was similar to the good-embryo group (36.8). In both groups, the percentages of fresh ET cycles were similar. The values for the mean birth weight and birth height of infants in the poor-embryo group were 3055 g and 50.3 cm, respectively, and there were no significant differences with the good-embryo group. The umbilical blood gas analysis in the poor-quality group was similar to that in the good-embryo group. There were no obvious major anomalies among the infants of either group. The perinatal outcomes of the poor-embryo group were comparable to those of the good-embryo group. Based on these results, we can provide qualified assurance for a normal perinatal outcome to patients who had no choice but to undergo embryo transfer with a poor-quality embryo.
