“…One impressive observation to emerge in the last decade is the finding that early insults to the mother can negatively impact the oocyte and lead to transgenerational effects. Studies in cattle revealed that even mild nutrient restriction during a narrow periconceptional window of time can lead to reduced ovarian reserve, aorta malformation, and hypertension in female progeny (Mossa, Latham, Ireland, & Veiga‐Lopez, 2019), demonstrating the high potential of maternal factors in impacting progeny health. Maternal exposure to low levels of environmental toxins (Hunt et al, 2003; Hunt, Susiarjo, Rubio, & Hassold, 2009; Lawson et al, 2011; Muhlhauser et al, 2009; Susiarjo, Hassold, Freeman, & Hunt, 2007), maternal obesity (Boudoures et al, 2017; Grindler & Moley, 2013), and potential effects of ovarian stimulation and oocyte/embryo in vitro culture and manipulations likewise can disrupt the fragile biology of the oocyte, impacting progeny health.…”
