How far can one go to violate another's integrity to "protect" an embryo?
Let's imagine a device called the Implantation Conducive Kit, or ICK. The ICK can be briefly inserted vaginally after sex and activated, which increases the chance for a blastocyst to implant in the uterine lining.
Does a woman have any obligation to use the ICK? If she has an obligation to gestate an entire pregnancy to term to satisfy PLers' desire for the embryo's survival, why not the comparatively smaller imposition of using the ICK?
Let's also imagine a couple, Eric and Lana, after consensual intercourse. Lana is on birth control and they are using condoms, but both of those have a chance to fail. Is Eric justified in pinning Lana down and forcing the ICK into her in order to "protect his child"?
If not, why do you get to violate a woman's integrity by forcing her to gestate a pregnancy to term, but Eric does not get to violate her for the same motivation?
