Abstract:

Objective

To evaluate the effect of coenzyme Q10 (CoQ10) supplementation on oocyte maturation rates and postmeiotic aneuploidy rates during in vitro maturation (IVM) of human oocytes.

Design

Clinical laboratory observation.

Setting

Hospital and university laboratories.

Patient(s)

Forty-five patients aged ≥38 years and 18 patients aged ≤30 years undergoing in vitro fertilization.

Intervention(s)

The germinal vesicle–stage oocytes and associated cumulus cells were cultured in IVM media for 24–48 hours with or without 50 μmol/L CoQ10. Oocyte maturation rates were determined based on the presence or absence of the first polar body. Postmeiotic aneuploidies were determined using next-generation sequencing analyses of biopsied polar bodies.

Main Outcome Measure(s)

Oocyte maturation rates, postmeiotic oocyte aneuploidy rates, and chromosome aneuploidy frequencies.

Result(s)

In women aged 38–46 years, 50 μmol/L CoQ10 significantly increased oocyte maturation rates (82.6% vs. 63.0%; P=.035), reduced oocyte aneuploidy rates (36.8% vs. 65.5%; P=.020), and reduced chromosome aneuploidy frequencies (4.1% vs. 7.0%; P=.012. In women aged ≤30 years, we failed to demonstrate an effect of CoQ10 on oocyte maturation rates or postmeiotic aneuploidies.

Conclusion(s)

CoQ10 supplementation during IVM increased oocyte maturation rates and reduced postmeiotic aneuploidies for older women.
