This study of 72 embryos from endometriosis patients undergoing IVF found no significant difference between time-lapse morphokinetics and pronuclear morphology assessment for determining embryo quality, though a weak correlation existed between pronuclear scoring and embryo quality.

This study compared time-lapse embryo morphokinetics monitoring with conventional pronuclear morphology assessment to evaluate embryo quality in patients undergoing in vitro fertilization for endometriosis. The researchers analyzed 72 embryos from 19 women and found no significant difference between the two methods in predicting good versus poor quality embryos. Although a weak correlation existed between pronuclear scoring and embryo quality, the authors attributed the lack of statistical significance in both methods to the small sample size and potential visual bias during observation. This paper is centrally about endometriosis — specifically examining how the condition affects embryo selection strategies during assisted reproductive technology cycles.

Abstract

ObjectiveEndometriosis patients who underwent IVF program has poorer embryo quality, leads to low successive rate. In order to determine embryo quality, time lapse embryo monitoring and pronuclear (PN) morphology assessment were used to predict and select the most promising embryo. This research is expected to exhibit comparison the use of both methods in endometriosis patients in order to implement the most effective evaluation in future embryo implantation prognosis.MethodsThis cohort research was conducted to 72 embryos from 19 endometriosis patients who underwent IVF program in Yasmin Reproductive Clinic, Cipto Mangunkusumo Hospital. After ICSI was performed two-nucleated embryo later be monitored by its cleavage time and would be classified into categories for good quality embryo and other classes were considered poor quality embryo for time lapse monitoring. Then from time lapse monitoring, PN morphology were assessed regarding pronuclear scoring.ResultsBased on 72 embryos observation, we found that there was no significant difference between good and poor quality embryo based on PN scoring with p=0.185, and also between time-lapse morphokinetic monitoring and embryo quality with p=0.526. However, we found that there was a weak correlation between PN scoring and embryo quality with p=0.049 and r=0.233.ConclusionThere was no significant difference found between time lapse monitoring and PN scoring in endometriosis patients in order to determine embryo quality. However, there was a weak correlation between PN scoring and embryo quality. This might be due to small number of samples taken and visual bias during observation.

Abstract

Objective Endometriosis patients who underwent IVF program has poorer embryo quality, leads to low successive rate. In order to determine embryo quality, time lapse embryo monitoring and pronuclear (PN) morphology assessment were used to predict and select the most promising embryo. This research is expected to exhibit comparison the use of both methods in endometriosis patients in order to implement the most effective evaluation in future embryo implantation prognosis.

Methods

This cohort research was conducted to 72 embryos from 19 endometriosis patients who underwent IVF program in Yasmin Reproductive Clinic, Cipto Mangunkusumo Hospital. After ICSI was performed two-nucleated embryo later be monitored by its cleavage time and would be classified into categories for good quality embryo and other classes were considered poor quality embryo for time lapse monitoring. Then from time lapse monitoring, PN morphology were assessed regarding pronuclear scoring.

Results

Based on 72 embryos observation, we found that there was no significant difference between good and poor quality embryo based on PN scoring with p=0.185, and also between time-lapse morphokinetic monitoring and embryo quality with p=0.526. However, we found that there was a weak correlation between PN scoring and embryo quality with p=0.049 and r=0.233.

Conclusion

There was no significant difference found between time lapse monitoring and PN scoring in endometriosis patients in order to determine embryo quality. However, there was a weak correlation between PN scoring and embryo quality. This might be due to small number of samples taken and visual bias during observation.
