I expect it was. I have a vague memory from a year or so ago, reading iirc a Jessica Rose Stack about an anonymous posting from 4-chan. The post was dated before or very early on in the jab rollouts. The poster claimed to be 1 of 2 young scientists working nights at pfizer manufacturing. Iirc, for pfizer jabs, there was a change in the normal mfg process which added a secret step. Curious, concerned the 2 scientists searched the office one night & found documentation of secret addition of a compound that was intended to cause the mrna or the spikes to aggregate into specific organs, including the testes & ovaries...the post went into significant technical detail, enough that at the very least they poster knew what he was talking about.

Again, it was dated very early on ... months before data on adverse effects began to emerge.

I never saw any mention of this post again, but it has been sitting in the back of my mind ever since ☹️

Certainly not the first instance of forced sterilization in history...
