TL;DR: The authors show that chromosome structure erodes only with advancing age, acting as a “molecular clock” for reproductive senescence, and suggest that chromosomal errors originating in oocytes determine the curve of natural fertility in humans.

TL;DR: The study results show an increase in precocious separation of sister chromatids and RS derived from localized centromeric and systemic cohesion weakening as women age, suggesting cohesion weakening may act as a “molecular clock” limiting reproductive capacity in AMAs.
Journal ArticleDOI
Use of cryopreserved ovarian tissue in the Danish fertility preservation cohort.

TL;DR: In this article, the authors evaluated the use of cryopreserved ovarian tissue in the Danish fertility preservation cohort and found that women aged ≥30 years at OTC were more likely to return for OTT than women aged 18-29 years at oTC; mean storage times were 3.7 and 3.6 years, respectively.
Journal ArticleDOI
A threshold concentration of FSH is needed during IVM of ex vivo collected human oocytes.

TL;DR: In this paper, the effect of different recombinant FSH concentrations on human oocyte maturation in vitro and its impact on gene expression of key factors in the surrounding cumulus cells was investigated.
Journal ArticleDOI
Human Oocyte Morphology and Outcomes of Infertility Treatment: a Systematic Review
TL;DR: In this paper, a systematic search in PubMed and Cochrane Controlled Trials Register following PRISMA guidelines was performed to determine a correlation between oocyte morphology and treatment outcome, and a total of 52 articles out of 6,755 search results met the inclusion criteria.
