Have you ever noticed that there are a lot of birthdays at the end of summer and start of autumn?
That's because so many babies get conceived around Christmas, and there are a host of reasons for that.
First of all, people have more free time and are drinking more, which can lead to friskiness and contraception going out the window.
It can also be hard to access contraception as GPs and pharmacies can be closed and pills get forgotten at home when women go away for the festive season.
On top of that, a recent study published in the Obstetrics and Gynaecology journal revealed that the quality of sperm produced in winter is better than in the summer months.
Women's ovum receptivity also increases because of the changes in the daylight length.
Great if you're trying for a baby, not so good if you aren't.
