title: Transgenerational inheritance of ovarian development deficiency induced by maternal diethylhexyl phthalate exposure.
abstract: Diethylhexyl phthalate (DEHP) is a widely used industrial additive for increasing plastic flexibility. It disrupts the physiological functions of endogenous hormones and induces abnormal development of mammals. The objectives of the present study were to evaluate the effects of DEHP exposure on ovarian development of pregnant mice and whether the effects are inheritable. We found that the synthesis of oestradiol in pregnant mice after DEHP exposure was significantly decreased, and that the first meiotic progression of female fetal germ cells was delayed. Furthermore, the DNA methylation level of Stra8 was increased and the expression levels of Stra8 were significantly decreased. An accelerated rate of follicle recruitment in F1 mice was responsible for the depletion of the primordial-follicle pool. Maternal DEHP exposure also significantly accelerated the recruitment of primordial follicles in F2 mice. In conclusion, our results indicated that maternal DEHP exposure induced ovarian development deficiency, which was transgenerational in mice.
