“…A substantial body of research has established that exposure to a non-optimal rearing environment early in life has long-term effects on developing neurophysiological pathways that may have profound implications for later development and health (Gunnar & Quevedo, 2007). While the influence of ELS exposure (e.g., parental depression, marital conflict) on later cortisol levels has been well established (Ashman, Dawson, Panagiotides, Yamada, & Wilkinson, 2002;Essex, Klein, Cho, & Kalin, 2002;Essex et al, 2011b;Koss et al, 2011Koss et al, , 2013, the effects of ELS on DHEA and testosterone have been less thoroughly examined.
