Seasonal changes in sperm quality

Quite a few news articles have come out about the recent study by Levitas et al in the American Journal of Obstetrics and Gynecology. This study did an in-depth statistical analysis of over 6,000 semen analysis and found that there were significant improvements in semen quality in winter and spring as compared to the summer and fall.

Birth statistics interestingly also show the most births in the months of September, August, June and July. There is some debates among academics about how much this matters. For example, this review article from the Oxford Journal of human reproduction states that the major reason behind seasonality of births is couples choosing when to go off birth control and try to conceive. While that is most certainly true, there might be some legitimate reasons why people are more likely to naturally conceive in the winter.

First. Baby making is way more pleasant in the winter when you want to get warm under the covers and not so much in the heat of summer. Second, as we explored, heat has a dramatic impact on sperm production. For guys who have lower than average natural production, the summer heat doesn’t help the situation.

What can you do? This study serves as a reminder that men need to be extra vigilant of overheating their testicles during the summer months.

Make sure your clothing is loose.
Don’t stand next to the grill for long periods of time.
Try to cool off with a dip in the pool.
Take breaks from outdoor work to cool off in the air-conditioning.
You can also get up, go buy her some flowers and get busy before it gets too hot.
