Did You Know? December is a Peak Month for Baby-Making

Did You Know? December is a Peak Month for Baby-Making

According to a study published in Obstetrics & Gynecology magazine (1), 9.1% of conceptions in the U.S. occur in December. What is it about this time of year that inspires people to start or increase their families? While there is no single answer to this question, there are a handful of studies that might shed some relevant, or simply entertaining, light on this interesting phenomenon.

One study found that twice as many condoms are sold in the week before Christmas than in the week after, which the authors suggest indicates “stockpiling” for the increased opportunities between Christmas and New Year’s for socializing and, perhaps, a “more hedonistic approach to life during that time.”

Another fun study (2) discovered that when the tax benefits of having children increases by $500, there is a 27% rise in the probability of a child being conceived as to be born in late December. People are incentivized to plan their pregnancies to have the birth occur before midnight, January 1.

Weather might play a part as well. While not exactly scientific, a “Degrees of Pleasure” study (3) by the makers of Trojan condoms reported that 35% of participants report refusing to have sex at least once “because I was too hot,” whereas only 19% had ever refused sex because they were too cold. The same study reported that 83% of Americans think rainy days or nights are the best time to have sex.

You can see that there are a variety of factors that may contribute to a rise in the number of conceptions in the U.S. during December. Have fun checking out the studies and stay warm!
