Could a pill be made that instead of preventing pregnancy induces a successful pregnancy after sexual intercourse? This article seems to answer my question and is what inspired it, but I'm not 100% sure.

    $\begingroup$ Certainly. One form of fertility treatment is to supply hormones, though as of about 20 years ago, it was injections rather than a pill, at least in my friends' case. (The result graduated from high school last year.) $\endgroup$

There are already hormonal treatments that increase ovules production in women: instead of 1 ovule per cycle, they induce the production of up to 20 ovules in a single cycle. Since likelyhood of pregnancy is proportional to the amount of available eggs, they do the trick.

It is important to note that a pregnancy with more than 1 embryo is something human body has not been selected for. The more the embryo, the higher the risks for both mother and embryo.

  • $\begingroup$ @Olga, yes, but when it's 1 egg vs millions of sperms (providing they are present), the egg is the limiting factor. $\endgroup$

  • $\begingroup$ @L.Dutch, in 30% of all infertility cases a man is the problem. Increased number of eggs will not solve it. A man should be treated. $\endgroup$

There are so many many factors required for pregnancy. Each one can stop it but everything has to be right for it to happen.

Imagine it as a chain. To stop it you just cut any link. To join the chain any link could be the problem.

No pill can fix everything that might stop it.

  • $\begingroup$ No nanobot pill would do it. It would have to fix everything from physical faults to editing DNA on the fly. The effort wouldn't make a pill worth it. Unless the nano bots had AI how would they know what to fix? Better to use IVF and an artificial womb to completely bypass the issues $\endgroup$

If the "pill" contained an already fertilized egg (zygote), then all it would have to do is get the egg to the right spot (nano-bots, or it's not a pill that's swallowed) and maybe have a few hormones to set the environment.

Intercourse isn't even required. As to who the egg's parents are...?
