Chromosome errors in human eggs shape natural fertility over reproductive life span
Open accessAbstract
Understanding fertility in young and old: Fertility in humans follows a U-curve, with low rates in both teenagers and women of advancing maternal age (mid-30s and above). Gruhn et al. found that this distinct shape originates from chromosomal errors in human eggs, which result in genomic imbalance and pregnancy loss. The error types and chromosomes affected in the young and advanced age groups were different, suggesting that two distinct chromosome-based mechanisms balance risk associated with pregnancy and evolutionary fitness as women enter and exit their reproductive life span. The authors show that chromosome structure erodes only with advancing age, acting as a “molecular clock” for reproductive senescence. Science , this issue p. 1466

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
