While it’s not clear why sperm are healthier in the winter, researchers theorize that semen is affected by warm temperatures, daylight exposure, and hormone variations.
If you’re trying to have a baby, a new study suggests that it’s best to try in winter and early spring, when men have healthier sperm.
Israeli scientists studied samples from more than 6,000 men who were being treated for infertility between January 2006 and July 2009.
According to the Daily Mail, researchers found sperm in greater numbers, with faster swimming speeds, and fewer abnormalities, in semen made during the winter -- which could account for the boom in childbirths in autumn. The sperm declined steadily in quality from spring onwards, the report says.
