Abstract

Oocyte numbers decrease whereas the incidence of aneuploidy increases as women age. The molecular mechanisms underpinning this age-related decline in oocytequality are not completely understood. Human oocytesare particularly error prone, with reports of aneuploidy rates as high as 50-60% (Fragouli et al.,2011;Kuliev etal.,2011). Mouse oocytes, in contrast, are generally more resilient to age-related aneuploidy, with different stains harboring disparate susceptibilities to chromosome segregation errors.This is clearly observed with aneuploidy rates as low as 9% (C57Bl/6 mice, 17-19 months) to 25% (B6D2F1/J mice,16-19 months), but may be as high as 33% (MF1 mice,15- 17 months) to43% (CD1 mice,19-25 months) (Chiang et al., 2010; Sebestova et al., 2012; Shomper et al., 2014;Yun et al., 2014).
