The expression of key steroidogenic proteins in the ovary of HFD-HF diet-fed rats showed decreased StAR, CYP11A1, 3βHSD, and 17βHSD (Figure 5C–E,G) as well as testosterone metabolizing enzyme P450 aromatase (Figure 5G), although CYP17A1 expression unaltered (Figure 5F). This evidence concerns the gene CYP17A1 and hydrops fetalis.
