It does that, and is also something many women desire. Some thigns are both really hard and painful, and also very rewarding.
I really doubt you are going to get any challenges from feminists, or at least not very many. Feminism is all about empowering women to be able to do what they want, which includes having a baby using an artificial womb. Conservative groups might be against it, but it will depend on which group. Not all conservative groups are against IVF, which is similar in the sense that it allows a woman who would otherwise not be able to have a child have a child.
