Hey, nanites would be a great way to just eliminate the ova that are ejected from the ovaries in a woman's body, thereby removing the need for mood altering hormone pills, cancer causing IUD's, sensation stealing condoms, etc. They could even be used to eradicate virii, like HIV, Hepatitis, other STD's, or even things like the common cold and flu virii. the possibilities for good are almost limitless.
