I believe in science, and I believe that someone will make this possible sometime in the future.
So, have you heard of in vitro fertilization? It is used to treat infertility or reproduction problems. Say, for example, that you're a FTM who marries a woman and you want to have kids with her. I have this crazy idea of taking an egg from each partner (assuming the ftm has found a way to preserve the eggs or hasn't had it removed) and either
A) find a way to fertilize one egg with the other egg, or
B) create a vessel that imitates (or imitates the function of) a sperm and put one partner's DNA into the synthesized sperm, then attempt to fertilize the egg, or
C) find a way to insert the DNA into an egg and trigger the same response a sperm would when the egg and sperm are joined
D) empty a sperm of its DNA without destroying it, inject DNA extracted from an egg in there, and fertilize the other egg
This would require more detailed research into the process of fertilization, more specifically the complete functions of the egg and the sperm and the sperm-egg interaction. It would also require techniques such as complete DNA extraction without damaging the DNA, sperm synthesis, a way to stimulate responses in an egg the way sperm would, and possibly many more...
It will probably be extremely controversial, but I refuse to let people-who-can't-mind-their-own-businesses stop me. One suggestion for studying these processes is to study them while doing in vitro fertilization for couples instead of fertilizing and then destroying the product, as it will be VERY controversial, even amongst the trans crowd.
*NOTE* you will only be having daughters with this process if you're a ftm. and for mtf, we will be trying to synthesize/imitate an egg
