Implication

Cohort study reveals that maternal age, infertility diagnosis, and gonadotropin dose correlate with oocyte aneuploidy, indicating multifactorial origins of meiotic division errors.

Key Points

To evaluate the incidence of oocyte aneuploidy in relation to patient characteristics, ovarian stimulation protocols, and follicular response.
Analyzed 4,163 first polar bodies from 706 assisted conception cycles across 544 infertile couples, including 640 poor prognosis cycles and 66 controls.
Performed chromosomal screening for chromosomes 13, 15, 16, 18, 21, and 22, assessing findings with multivariate analysis.
The proportion of normal oocytes was directly correlated with mature oocyte yield and clinical pregnancy establishment (P < 0.01).
Normal oocyte rates were inversely correlated with female age, infertility causes such as endometriosis, ovulatory factors, repeated abortions, poor prognosis indications, and higher FSH units per oocyte (P < 0.01).
Types of meiotic division errors (chromatid predivision, non-disjunction, or combined mechanisms) were weakly associated with clusters of clinical variables rather than individual risk factors (P < 0.05).
