Mating season: How the changing seasons affect human fertility and pregnancy

We’ve all heard loud, awkward meowing coming from a cat before and thought, “Oh, well it must be in heat.” We think that instinctively, without even considering the fact that it’s in the midst of a very cyclical reproductive cycle.

According to the Statistic Institute of Quebec, humans seem to have more fertile periods than animals in a year. Where we differ from our animal friends, however, is that more of those periods are opportunities for us to give birth.

It’s interesting to note that, during these 10 years, July, August and September are most often in the top-three most popular birth months. Perhaps the cold weather causes couples to shack up, as November is when most babies are conceived in Quebec.

Meanwhile, children born in November and December tend to suffer from asthma, while those born in August suffer from rhinitis, and December and January births have conjunctivitis issues
