As a Pagan scholar, this makes me think about goddesses who created life by themselves, without assistance from a god. Parthenogenetic life formation relates closely to a shift from celestial water to cthonic water. Alternatively, one might argue that either underworld gods are more life-oriented than formerly thought, or we should really be looking for cthonic goddesses. On the third hoof, this raises interesting points regarding those underworld deities who are hermaphroditic. This could make for some fascinating ritual inspiration.
