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
This is just something they have evolved to do, while we have not.
The tech we have today is nowhere close to offering the same level of sex change that these animals are capable of. At best, we can alter hormones and perform surgeries that result in the mimicking of the opposite sex’s phenotype. Eventually, tech may allow complete and safely reversible sex change. At that point, changing your sex may be akin to getting a haircut.
It’s kind of how some animals can regrow limbs. Current tech can’t, but prostheses are a thing we can do, and this can mimic some (but not all) of the functions of the lost limb.
Efit: if you’re looking into specifics, their bodies develop in such a way where switching is easy and they keep this qbility for most of their lives, for humans, we generally lose the ability to switch easily at around 6 weeks of gestation.
