This prospective cohort study of 20 women undergoing IVF examined whether cumulus cell mitochondrial respiratory activity relates to the maturity of the corresponding oocytes. Cumulus cells from 327 oocytes were assessed by flow cytometry using mitochondria-specific dyes, and respirometric stress analysis with the ATPase inhibitor oligomycin was used to derive a respirometric index (O′R) reflecting mitochondrial metabolic abnormalities. Cumulus O′R strongly correlated with maternal ovarian reserve (higher AMH), and cumulus cells from immature oocytes showed more severe mitochondrial deficiency (lower O′R) than those from mature oocytes, while O′R did not differ between cumulus cells associated with good versus poor-quality embryos. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Purpose Oocyte competence is critical in success of assisted reproduction. Metabolic signaling between oocyte and cumulus cells within the cumulus-oocyte complex procure oocyte development. This study evaluated the relationship between respirometric activity of cumulus cells and maturity of corresponding oocytes.

Methods

In prospective cohort study, 20 women of age 28–42 undergoing IVF procedure were involved. To evaluate oocyte maturity, the cumulus cells from individual oocytes were assessed flow cytometrically by double labeling of cells with mitochondria specific dyes. The respirometric stress analysis using ATPase inhibitor oligomycin was applied to assess mitochondria metabolic abnormalities.

Results

The cumulus cells from each of 327 oocytes were analyzed. The respirometric index of cumulus cells (O′R) strongly correlates with maternal ovarian reserve, showing to be higher in patients with higher AMH (p < 0.0017). Cumulus cells from immature oocytes had severe mitochondria deficiency, i.e., low O′R, than those from mature oocytes (p < 0.02). No significant difference in respirometric capacity was found between cumulus cells associated with good vs poor-quality embryos.

Conclusions

The oocyte maturity is potentially related to the mitochondria activity of cumulus cells. Similar content being viewed by others
