I'm not sure. A lot of relationships are breaking down because they've either become long-distance contactless relationships or the couple's been cooped up for months on end with nothing to do but stare at each other until they couldn't stand the sight of the other.
Domestic violence and child abuse are increasing in some areas because everyone's cooped up together, and there are fewer opportunities for the victims to seek help by going to a shelter, some other agency, or for kids to talk to a teacher they trust.
As for "nothing to do but eat and procreate"... has this doctor never heard of work, school, TV, reading, writing, going for walks (where permitted), playing board games, cooking, shopping (where permitted), and so forth?
I'm spending this pandemic in my apartment, hanging out with CFCOT, a couple of other forums, reading and posting on my news site, telling my MLA off several times a week on FB, writing every day - anywhere from a sentence to a couple of thousand words, reading novels and fanfiction, feeding and cuddling Maddy, and a variety of other things. I've been outside 6 times since March (delivery people are less afraid to deliver here if they know I've been staying home and not being careless by going out in crowds).
Now that I've found my portable lap desk, the coloring books and pencil crayons are going to be used (adult coloring is a thing, and one of my friends on another forum is into it).
The issue of baby booms was brought up on our news site a few months ago, and the general view is that there actually won't be one. People are too afraid to get that close, if they work at jobs that bring them into contact with a lot of other people who may be asymptomatic spreaders. I wouldn't want to be a school teacher right now, for instance. Some schools in my province still have 30 kids crammed into classrooms where the 2-metre rule for social distancing is impossible and the government is not inclined to be very helpful to kids whose families can't afford masks.
