People can change their sexual characteristics with hormone therapy and surgeries, but having the reproductive capacity of the opposite sex is unfortunately not possible; while uterus transplants are theoretically possible, even then, a donor/IVF would be needed because the ovaries wouldn’t have eggs with the mother’s DNA. So how can some animals do what we with all of our technological advancements can’t?
In: Biology
Oysters and fish do not have a uterus.
For those that change sex under certain conditions, such as clownfish, they are essentially born hermaphrodites, with hormonal changes controlling which set of organs are active.
That is, the dominant fish in a group has their ovaries activated, while their testes stop. You see similar dominance-based hormonal changes in other animals (such as gorilla), but they activate different processes (such as loss of hair pigment).
