Table 1 List of studies showing effect of stress on ROS production and oocyte quality

1.

Stressful life events cause release stress hormone and impair follicular maturation in ovary

Human

Lancastle and Boivin, 2005 [7], Ebbesen et al., 2009 [5]

2.

Stressful life events leads to maladapted lifestyle behaviours i.e. alcohol and cigarette consumption
