Cold Winter Nights May Be The Best Time For Making Babies

sperm motilityCouples looking to conceive may want to start to take advantage of those winter days when it’s too cold to leave the house. While the cold may cause shrinkage, it seems that sperm perform best in the winter months, according to a new study.

The study performed by researchers at Ben-Gurion University of the Negev in Israel found that in the winter sperm is more abundant and faster moving. In the winter, five percent of the sperm tested had fast “sperm motility” as compared to only three percent in the spring. The faster the sperm travels the better the chances a couple has to conceive:

Based on samples from more than 6,000 men treated for infertility, researchers  writing in American Journal of Obstetrics & Gynecology found sperm in  greater numbers, with faster swimming speeds and fewer abnormalities in semen  made during the winter, with a steady decline in quality from spring onward.

This rang true for men with “normal” sperm production but not for men with infertility problems.

“Based on our results the (normal) semen will perform better in winter, whereas  infertility cases related to low sperm counts should be encouraged to choose  spring and fall,” the researchers wrote.

So maybe if another winter snowstorm arrives before spring rolls in next week, there will be a boom in Christmas babies.
