You can permanently transform every breeding-aged woman on the planet any way you like

The same thing I'd do the last time you posted this thread: give them all an insatiable need to be knotted by dogs and make it where they can have puppies.

Everyone will thank this user later.

It's not a change or transformation, but it would lead to one:

Earth is invaded by a species of raping aliens that completely ignore men and can phase through any matter on their quest to thoroughly impregnate every human female on the planet.

With a week, every reproductive-aged woman on the planet is stuck weeping with an unabortable brood of alien spawn growing in her rapidly-swelling belly…

Do they understand they can be knocked up by the dogs as this irrational new desire starts to catch hold in their minds, or is that just a nasty surprise for later?

Also, this applies to all women, even lesbians and feminists?

Yes, and especially lesbians and feminists.

A brain reboot, such that they again know instinctively how to clean and make food and can sense when their man wants his dick sucked.
A physical upgrade too, since two cunts are better than one and I'd prefer it if she slept upright in the closet.

Especially fun to imagine the women who have the most phobias and hangups regarding human cocks and hetero human sex gradually find themselves (much to their dawning horror) daydreaming about submitting themselves like true bitches in heat to dogs, to the point that - after just a few weeks - no woman, especially a dyke or feminist - can find herself around a male dog without imagining what the taste and texture of that dog's cock in her mouth, cunt or ass would be like, or what it would be like to be owned and collared like whatever female dog they see, to the point that those women quickly find themselves dripping and resisting the urge to get on all fours right there and fuck that male dog, or take the female dog's place at the end of its leash…

turn them all into men just to fuck with society

That kind of Stepfordization would be fantastic, especially if it's slow and gradual and, like in

is even worse for lesbians and feminists, who need that forced reprogramming the most.

I'd give them all the ability to earn equal pay.
