Abstract

In recent years, postponement of marriage and childbearing in women of reproductive age has led to an increase in the incidence of age‐related infertility. The reproductive aging process in women is assumed to occur due to a decrease in both the quantity and quality of the oocytes, with the ultimate result being a decline in fecundity. This age‐related decline in fecundity is strongly dependent on oocyte quality, which is critical for fertilization and subsequent embryo development. Aged oocytes display increased chromosomal abnormality and dysfunction of cellular organelles, both of which factor into oocyte quality. In particular, mitochondrial dysfunction has been suggested as a major contributor to the reduction in oocyte quality as well as to chromosomal abnormalities in aged oocytes and embryos. Participation of oxidative stress in the oocyte aging process has been proposed because oxidative stress has the capacity to induce mitochondrial dysfunction and directly damage many intracellular components of the oocytes such as lipids, protein, and DNA. In an attempt to improve mitochondrial function in aged oocytes, several therapeutic strategies have been investigated using both animal models and assisted reproductive technology. Here, we review the biological mechanisms and present status of therapeutic strategies in the female reproductive aging field and indicate possible future therapeutic strategies.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Aging processes can be accentuated at etiologic sites of multiple acute and chronic diseases, including in children.

    “Aging progresses throughout the lifespan can be accentuated at etiologic sites of multiple acute and chronic diseases, including in children6,8–12.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [12]

    The ‘Contribution of oxidative stress to oocyte aging’ section (page not provided) links oxidative stress to aging and aging-related diseases, and the ‘Calorie restriction’ section names several such diseases. Neither section says that aging is accentuated at the etiologic sites of acute and chronic diseases or that this occurs in children. (LLM, conf=0.79)

    Experimental — accuracy not yet measured
  • Fundamental aging processes can act before conception, as with aged oocytes linked to Down syndrome.

    “fundamental aging processes can operate even before conception, for example, in the context of aged oocytes linked to Down syndrome12,13.”

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.
