Why do hyenas have both sexes?
Female spotted hyenas have androgens (hormones) in their systems. These substances are associated with dominance and social status. It’s thought that high levels of testosterone are transferred to male and female offspring through the placenta. This exposes both sexes to a high level of maleness during gestation.
Can female hyenas mate with other females?

In most animal societies, members of one sex dominate those of the other.
