If you got it on over the holidays, you were not alone.
But seriously, according to multiple studies, December has the highest rate of conception of any month.
“1. Conception rates reach their annual peak in December, with 9 percent of all U.S. conceptions occurring during that month.
August is the annual “trough,” with the year’s fewest number of conceptions. The University of Texas–affiliated study that yielded this stat confirms similar findings in many other studies showing that most babies are born in late September, while the fewest are born in April. “Biologic hypotheses include deterioration of sperm quality during summer, seasonal differences in anterior pituitary-ovarian function caused by changes in the daylight length, and variation in quality of the ovum or endometrial receptivity,” the study’s authors write. “Increased sexual activity associated with end-of-year holiday festivities has also been postulated.”…

“2. More than twice as many condoms are sold in the week before Christmas than in the week after Christmas.
This sales pattern is “strongly suggestive of an acute increase in sexual activity over the Christmas period,” write the authors of the scholarly study that yielded this stat. “The sharp increase in sales in the week before Christmas and the sharp fall in sales in the week after Christmas indicate some stockpiling.” The rise in sexual activity during late December “has been interpreted largely in the context of merrymaking. The period from Christmas to the New Year is associated with increased opportunities for socializing and a generally more hedonistic approach to life,” the authors write.”…
“4. When the tax benefits of having a child are increased by $500, the probability of that child being conceived so as to be born during the last week of December rises by 27 percent.
Does the idea of a refund make you hot? “Because the annual tax savings associated with a birth are realized if the birth takes place any time before midnight January 1, parents… have an incentive to time the birth at the end of December rather than at the beginning of January,” write the authors of the Syracuse University–affiliated study that yielded this stat.”
What are other high-conception times?
The Daily Beast reports: “At midnight, during spring break, when it rains, and when they haven’t just lost their jobs, recent research reveals.”
Apparently Michael and I go against the grain. The article reports that the summer is actually a low conception time (they think because it’s hot people aren’t doing it) but that’s when we conceived all three kids. It’s called AC people. Get some.
What do you think of December being the highest conception time? Do you think it’s for a tax write off or because people are celebrating? Did you fall into any of the high-conception times?
