The impact of oxidation-reduction potential in follicular fluid on intracytoplasmic sperm injection outcomes.

OBJECTIVE

Follicular fluid (FF) oxidation-reduction potential (ORP) has shown promise as a predictor for in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes has been demonstrated. This study aimed to determine the association between the ORP in FF and IVF/ICSI outcomes.

METHODS

This cross-sectional study involved data collection from 341 couples undergoing IVF/ICSI treatment. The FF sample was taken from the first follicle to exceed 18 mm during oocyte retrieval and was analyzed for ORP using the MiOXSYS system (Caerus Biotechnologies).

RESULTS

ORP in FF exhibited a statistically significant negative correlation with the fertilization rate (correlation coefficient, -0.126; p=0.019). The ORP levels in the FF from the group with a lower fertilization rate (<80%) were significantly higher than those in the group with a higher fertilization rate (≥80%) (89.90 mV vs. 78.98 mV, p=0.030). No significant correlations were found between ORP in FF and other outcomes.

CONCLUSION

Our findings suggested that the ORP in FF may be correlated with the fertilization rate and could be evaluated as a predictor of fertilization in ICSI.
