At this point we've added mode of consequence to the analogy, but it seems you're introducing yet another constraint: active and passive intervention. I'm afraid I'll have to stop this here. It appears as though you will continue adding complexity until with the intention of forcing your result. Sorry, I don't debate with people acting in bad faith.
If you're really deeply committed to this analogy, we would have to suppose a world in which everyone knows that voluntary sex produces children with an organ deficiency which can only be satisfied by a donation from one parent.

Pointing out that your analogy fails to capture the relevant dynamics isn't "acting in bad faith".
EDIT: Removed some snark.

But your analogy doesn't capture the responsibility of the donor for willfully creating the circumstances in which the recipient needs a kidney. Moreover, abortion is a procedure which actively kills a child which would likely otherwise live (without intervention); your analogy supposes a person who would naturally die without intervention. I'm sure we could contort your analogy to make it account for these things, but doing so would exhaust its utility.
