Have you ever wondered why there seems to be an explosion of very pregnant women during the summer?
Your eyes aren’t playing tricks on you. There’s evidence that our fertility may be influenced by the seasons and that paying attention to this could influence your chances of conception. Over the past decade, July has been the most popular birth month, with August a close second, according to the U.S. Census.
If most babies are born in the summer, it means they were conceived in the autumn: October, November, or December. Some experts believe the summer birth rate bump is tied to fall holidays and family vacations, when couples spend more time together.
Another hypothesis holds that cooler fall temperatures make some couples feel more frisky after a hot summer. And the brisk, cool weather is also good for sperm production, which can be decreased in summertime.
