Draft Registration Under Sex At Conception Policy

I’m trying to wrap my head around a potential legal challenge involving draft registration under the recent sex-at-conception definition.

Specifically what I'd like to understand is how the recent shift in the definition of sex—specifically the idea that sex is determined at conception—could affect draft registration, and I’m considering whether a legal challenge is viable. According to the new executive order, sex is defined from the moment of conception, which means that everyone is legally considered female initially. This is because all human embryos start with the same basic anatomy—female—before differentiation occurs later in development.

Given this, I’m concerned that, legally speaking, everyone would be considered female from the moment of conception. However, under current law, only males are required to register for the draft. If individuals are legally classified as female from conception under this policy, how can the law still require those individuals—who are now legally female—to register as males? This seems to create a major legal contradiction.

I’m wondering if this could be challenged under equal protection, as it appears to treat people differently based on a gender identity they didn’t choose. Could this be considered a form of forced gender reassignment, with the government retroactively assigning a gender to people? And, by imposing this gender classification, does it violate bodily autonomy, especially when it conflicts with military obligations?

I’m interested in feedback from anyone with legal experience on whether this could stand up in court or if there are any similar cases I should be aware of.
