If you're trying to have a baby and undergoing fertility treatment, you may want to intensify your efforts during the winter months.
According to new research, men have healthier sperm during the winter and early spring, boasting larger numbers, faster swimming speeds and fewer abnormalities.
The discovery was made when scientists in Israel studied samples from more than 6,000 men being treated for infertility.
It was observed that the quality of the semen declined from spring onwards, not reaching its optimum quality until the cold returned.
Researchers believe this is partly why more babies are born in the autumn, but remain unsure as to why sperm health is seasonal.
However, it thought that temperature, daylight exposure and hormone variations have some effect on the performance of semen.
Giving advice for those trying for a baby, Dr Edmund Sabanegh, a urologist, told Reuters Health: "We would continue to encourage them to try regardless of the season, and they may benefit from interventions or treatments."
