The effect of oocyte denudation time and intracytoplasmic sperm injection time on embryo quality at assisted reproductive technology clinic - A cross-sectional study.

ABSTRACT:

Background

This study aims to determine whether there is an effect of oocyte denudation time and ICSI time on embryo quality at assisted reproductive Technology clinic.

Methods

An observational analytic retrospective study was conduct using cross-sectional study. The subject were oocytes from in-vitro fertilization procedures using the ICSI method at the assisted reproductive technology clinic in a private hospital in Bandung for the period 2017 - 2019. Three variables were oocyte denudation time, ICSI time and embryo quality collected from samples that met the research criteria. Data will be grouped based on denudation time (T₁) and Intracytoplasmic Sperm Injection time (T₂).

Result

From the 5 groups of denudation time; 3-4 hours, 4-5 hours, 5-6 hours, 6-7 hours and more than 7 hours group, the denudation time of 3-4 hours group showed the highest number (66.7%) for excellent embryo quality results, while denudation time of more than 7 hours showed the lowest number (29.2%) for excellent embryo quality results with p < 0.001. From these figures, it shows that the ICSI time of 3-4 hours is superior to the ICSI time of 2-3 hours because the outcome of excellent embryo quality is higher while the outcome of poor embryo quality is lower, although the difference is not significant (p = 0.140).

Conclusion

This study shows there was a significant difference in the effect of oocyte denudation time on embryo quality at assisted reproductive technology clinic. There was no significant difference in the effect of intracytoplasmic sperm injection (ICSI) time on embryo quality at assisted reproductive technology clinic.
