How are hyenas not infertile?
This might be a dumb question, I don’t really know, but in humans and it seems the majority of mammals, males with high estrogen/low testosterone are typically infertile. Same with females with high testosterone/low estrogen. But in hyenas it is the norm for the females to have much higher testosterone than males to the point their clitorises develop to look like the male’s penis from outside. My question is why don’t their hormone levels effect their fertility the way it would if say a human had equivalent levels?
