We have CRISPR And LOCKR, soon we'll be able to perform circumcisions before the child is even conceived. Agenesis of the foreskin happens occasionally, it will be easy to figure out. Ultimately, after a period where the population is brought before a board periodically to justify their existence (taking into account their Social Credit), the entire population will be sterilized as we move to artificial wombs. They wombs will be draw from a massive database of genetic material, and will be managed by an AI. People will only be created when they have a reason to exist, every aspect of their composition, every step of their development, will be meticulously controlled. In this, we can and perhaps should clamp the umbilical cord prenatally, like the epsilons in Brave New World.

Vaccinations will be a thing of the past, the pseudoscientific quasireligious pretext of preventing disease no longer being necessary to have access to a population's bloodstream. In the early days, they'll use electorporation to put genes in you which will guarantee a constant immune response, for example, against your own sex hormones. No sexy fun time for you, slave. It is bad for social stability. You will not even know such things ever existed. We see this in The Giver. When you reach this level though, where sexuality is now more a liability than an instrument of control, it would be best if everyone was just androgynous. Now, even undeveloped from lack of sex hormones, over a lifetime a single penis, pair of ovaries, breasts, etc will take some number of calories to maintain. If you take that number times a billion+, that's a lot of wasted calories. No, it will not do. The concept of a body needs to be slimmed down. No more genitals. We can reduce and modulate brain function as well, for example, through microwave radiation and insertion of "magneto protein" expressing genes.

An EMF/EMR responsive nanomachine network will control bodily processes not unlike a parallel nervous system.
