Who did Achilles get pregnant?

I must say, the question of "Who did Achilles get pregnant?" strikes me as quite peculiar, given the context of Achilles' story in Greek mythology. Achilles, being a renowned warrior and hero of the Trojan War, was a male figure renowned for his strength and prowess on the battlefield. As such, the biological mechanism of pregnancy, which is inherent to female biology, simply does not apply to him. So, could you perhaps clarify your inquiry or if there's been a misunderstanding in the phrasing? Are you perhaps referring to a different figure or story entirely, or is there a specific angle or metaphor you're aiming for with this question? Understanding the context and intent behind your question would help me provide a more accurate and relevant response.
