If this is the case, this doesn't make sense. Unless the body halts the growing of the uterine lining when resources are low and it 'knows' the sex of the embryo somehow and therefore determines boy eggs to be harder to carry and miscarries it. But none of this was at all implied in the article and there's definitely no plausible reason given for a body to abort an egg deemed male. Also, a fairly small sample combined with a somewhat small statistical difference further deems the study weak. I assume the ratio of men-women in the world is always close to 50/50 but never consistent in our long history. Even if you believe investing in a male child is better for covering the world with your amazing genes, wouldn't you then always produce males? Or at least produce more males than females no matter what the conditions?
