Gonad development in some fish is controlled by fine‐tuned exposure to steroids. For example, genetically female (XX) medaka can be induced to form testes in the presence of cortisol. Kitano et al. (this issue) demonstrate that 17β‐estradiol can rescue this masculinization process, as demonstrated by this false‐colored image of the ovary‐filled gonad obtained from such a fish.
