Q1: Consensus is that females are born with all the eggs they’ll ever have. So if they’re damaged by the mRNA, immune system, and/or the plasmids, that’s permanent.
MRI: that could show you the scar tissue in the heart, but doesn’t necessarily tell you anything about damage to gametes. For example, a person who got a low concentration in the dose could’ve been injected into a blood vessel, which goes straight to the heart. And another person could’ve had a 1000x stronger dose, but not into a blood vessel. Lots of variables.
On pods: I’ve listened to every Darkhorse over 4 years so they blend together. I’ll see if I can find one or two. I can’t recall any specific episode about gametes, but it does come up periodically. AFAIK it’s still a big unknown elephant in the room.
Unvaxxed is ideal, as it also shows courage and a resistance to propaganda. But they could lie about their unvaxxed status. You could extract some eggs (for in vitro) and analyze them.
