Abstract
This chapter covers the known effects of endocrine disrupting chemicals (EDCs) on reproductive disorders. The EDCs represented are highly studied, including plasticizers (bisphenols and phthalates), chemicals in personal care products (parabens), persistent environmental contaminants (polychlorinated biphenyls), and chemicals in pesticides or herbicides. Both female and male reproductive disorders are reviewed in the chapter. Female disorders include infertility/subfertility, irregular reproductive cycles, early menopause, premature ovarian insufficiency, polycystic ovarian syndrome, endometriosis, and uterine fibroids. Male disorders include infertility/subfertility, cryptorchidism, and hypospadias. Findings from both human and animal studies are represented.

Abstract
An adverse tendency induced by the environmental estrogens in female reproductive health is one serious problem worldwide. Diethylstilbestrol (DES), as a synthetic estrogen, is still used as an animal growth stimulant in terrestrial livestock and aquaculture illegally. It has been reported to negatively affect ovarian function and oogenesis. Nevertheless, the mechanism and toxicity of DES on oocyte meiotic maturation are largely unknown. Herein, we found that DES (40 μM) intervened in mouse oocyte maturation and first polar body extrusion (PBE) was decreased in vitro. Cell cycle analysis showed meiotic process was disturbed with oocytes arrested at metaphase I (MI) stage after DES exposure. Further study showed that DES exposure disrupted the spindle assembly and chromosome alignment, which then continuously provoke the spindle assemble checkpoint (SAC). We also observed that the acetylation levels of α-tubulin were dramatically increased in DES-treated oocytes. In addition, the dynamics of actin were also affected. Moreover, the distribution patterns of estrogen receptor α (ERα) were altered in DES-treated oocyte, as indicated by the significant signals accumulation in the spindle area. However, ERα inhibitor failed to rescue the defects of oocyte maturation caused by DES. Of note, the same phenomenon was observed in estrogen-treated oocytes. Collectively, we showed that DES exposure lead to the oocyte meiotic failure via impairing the spindle assembly and chromosome alignment. Our research is helpful to understand how environmental estrogen affects female germ cells and contribute to design the potential therapies to preserve fertility especially for occupational exposure.

Abstract
UNLABELLED Recent evidence suggested a positive correlation between environmental estrogens (EEs) and high incidence of abnormalities in male urogenital system, but the mechanism remains unclear. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the morphology and proliferation of gubernaculum testis cells, but the underlying mechanism is unclear. In this study, mouse gubernaculum testis cells were pretreated with phospholipase C (PLC) inhibitor U-73122 and then treated with DES. The results demonstrated that U-73122 impaired DES-evoked intracellular Ca2+ mobilization in gubernaculum testis cells and inhibited DES-induced proliferation of gubernaculum testis cells. Mechanistically, we found that U-73122 inhibited DES-induced activation of cAMP-response element binding protein (CREB) in gubernaculum testis cells. In conclusion, these data suggest that the effects of DES on mouse gubernaculum testis cells are mediated by PLC-Ca2+ -CREB pathway. SIGNIFICANCE OF THE STUDY Environmental estrogens remain a serious threat to male reproductive health, and it is important to understand the mechanism by which EEs affect the male productive system. Here we explore potential mechanisms how the proliferation and contractility of gubernaculum testis cells are regulated by diethylstilbestrol. Our findings provide the first evidence that PLC-Ca2+ -CREB signalling pathway mediates the nongenomic effects of diethylstilbestrol on gubernaculum testis cells. These findings provide new insight into the role of diethylstilbestrol in the aetiology of male reproductive dysfunction and will help develop better approaches for the prevention and therapy of male reproductive malformation.

Abstract
BACKGROUND Hormonal effects on the gubernaculum can affect testicular descent. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the outgrowth of gubernaculums, leading to testis maldescent. However, the underlying mechanisms remain elusive. MATERIAL AND METHODS The gubernaculum were removed from 3-day-old mice and cultured. The subcultured cells were randomly divided into a normal control group and experimental groups. The DES groups were administered 10 μg/ml, 1 μg/ml, 0.1 μg/ml, 0.01 μg/ml of diethylstilbestrol dissolved in dimethyl sulfoxide (DMSO) respectively. The cell morphology was observed under an inverted microscope, and leucine-rich repeat-containing G protein-coupled receptor 8 (LGR8) was localized by immunofluorescence. The expressions of LGR8 gene and protein in gubernaculum cells were quantified by RT-PCR and Flow Cytometer respectively. RESULTS DES treatment converted cells from a normal fibroblast-like morphology into a more refractile, spindle-shaped morphology or irregular elliptical shapes along with cytoplasmic shrinkage. LGR8 was expressed in the cytoplasmic membrane, DES dose-dependently downregulated LGR8 expression at low doses (≤1.0 μg/ml), but upregulated LGR8 at high doses (10 μg/ml) at both the mRNA and protein levels. CONCLUSIONS These results suggest that DES causes testicular maldescent by altering the LGR8 pathway in mouse gubernaculum testis cells.

Abstract
Recent evidence suggested a positive correlation between environmental estrogens (EEs) and high incidence of abnormalities in male urogenital system. EEs are known to cause the abnormalities of testes development and testicular descent. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the morphology and proliferation of gubernacular cells, and its nongenomic effects on gubernaculum testis cells may be mediated by G protein-coupled estrogen receptor (GPER). In this study, we detected the expression of GPER in mouse gubernacular testis and investigated the effects of DES on the expression of GPER in gubernaculum testis cells. RT-PCR analysis revealed that GPER mRNA was expressed in the gubernaculum. GPER protein was detected in the parenchymal cells of the gubernaculum early in development. Furthermore, we demonstrate that GPER inhibitor G15 relieved DES-induced inhibition of GPER expression in gubernaculum testis cell, but ER inhibitor ICI 182780 had the converse effects on DES-induced inhibition of GPER expression in these cells. These data suggest that the effects of DES on mouse gubernaculum testis cells are mediated at least partially by the regulation of GPER expression.

Abstract
The etiology of testicular dysgenesis syndrome is multifactorial and involves environmental factors, such as environmental estrogens. Several studies have shown that hormonal effects on the gubernaculum may affect testicular descent. Diethylstilbestrol (DES) is a nonsteroidal synthetic estrogen that disrupts the morphology and proliferation of gubernacular cells, but the underlying mechanisms remain elusive. In this study, we aimed to determine whether DES may regulate the function of gubernaculum testis cells by way of nongenomic effects mediated by G protein-coupled estrogen receptor (GPER). We used cultured mouse gubernacular testis cells to demonstrate that GPER is expressed in gubernaculum testis cells. Erk1/2 inhibitor PD98059, PKA inhibitor H89, and Src inhibitor PP2 relieved DES-induced inhibition of gubernaculum testis cell proliferation, but ER inhibitor ICI 182780 had no effects on DES-induced inhibition of gubernaculum testis cell proliferation. In addition, we found that DES induced the activation of CREB downstream of PKA, Src, and ERK1/2 in these cells. These data suggest that the effects of DES on mouse gubernaculum testis cells are mediated at least partially by GPER-protein kinase A-ERK-CREB signaling pathway.
