“…In zebrafish, in vitro exposure of stage IV oocytes to malathion, di-(-2-ethylhexyl) phthalate, and genistein impairs oocyte maturation, whereas in vitro exposure to diethylstilbestrol, melatonin, and iprodione can induce oocyte maturation (Carnevali et al, 2010(Carnevali et al, , 2011Maskey et al, 2019;Tokumoto et al, 2005Tokumoto et al, , 2007. Exposures of maturationally competent oocytes in vitro to malathion, an organophosphate insecticide, causes a dosedependent decrease in the success of oocyte maturation in common carp (Cyprinus carpio) and zebrafish (Haider et al, 1988;Maskey et al, 2019). Alteration to the success of oocyte maturation by anthropogenic chemicals is proposed to be mediated by dysregulation of or interaction with the mPR (Das & Thomas, 1999;Maskey et al, 2019;Nagahama & Yamashita, 2008;Tokumoto et al, 2007Tokumoto et al, , 2011Kjeldsen et al, 2013).…”
