No.
1. There are lots of fertility clinics & frozen ova & sperm in the nations of Western Civilization, especially the US & Northern & Western Europe. & frozen embryos, for that matter. As the scenario doesn't posit mass disruption to technical societies, I assume that the power & utilities & comms & transportation are still up & running. In that case, I would expect CDC or the U.S. Army Biological Warfare Laboratories in Maryland or some other agency (if it doesn't exist already) to take over the effort of bringing embryos to term. & working with frozen ova & sperm to see if viable embryos can be teased out of the raw material.
2. Efforts would also be made to understand what caused the near sterilization, & to see what could be done to reverse the condition. But I would expect the main effort to go into trying to bring more embryos to term - as proof of concept, if nothing else. If the embryos can be brought to term, then perhaps the ova & sperm can also produce embryos & go to term.
3. Would the wealthy or powerful take on the US government and military & police? I don't think so - & if the situation evolves into a do-or-die crisis, government has a monopoly on sanctioned violence. The US military & government already have continuation of administration & military plans in place - & repurposed missile silos & deep caverns & etc. that can be converted into long-term living space, if need be. Nuke subs with skeleton crews are another possibility. Their power plants are good for 20 years (?), they can generate their own water, oxygen, trace elements. If they can work out taking on fish & plant material without surfacing, & processing that into reasonable food, they could last a long time underwater.
The needed biomedical expertise would be pretty well spread around. The military already has a lock on some of the more promising refuges, if it comes to that. & the military has the discipline & weapons & trained personnel, if push comes to shove.
