In men, too much fast food means lower fertility because they get fat and nobody wants to, you know, get with ‘em. But there’s a downside for women, too. A study published in the Journal of Human Reproduction identified a link between women’s pre-pregnancy diets and the length of time it took them to conceive. Among the over 5,000 women surveyed, those who ate fast food 4 or more times per week (holy cow!) took about a month longer to conceive than those who rarely or never ate it. Similarly, women who ate fruit fewer than 1 to 3 times a month (what the…?) took longer to conceive than those who reported eating fruit 3 or more times per day. Many other foods were examined for effect, but fast food and fruits showed the largest impacts. Can we all just agree that McDonalds is terrible and move on? Also, here’s a recipe for the best burger ever. Mixed messages much?
It seems like every day there’s another study that says pregnant women should do [insert-whatever-here] to have the best/strongest/most powerful baby. Well here’s one that requires minimal effort from expecting moms who already sleep on their side. A British study of over 1,000 women found that sleeping on one’s side is 2.3x less risky than sleeping on one’s back. But don’t stress if you wake up in the middle of the night on your back after having fallen asleep on your side. The study authors literally say, “What I don’t want is for women to wake up flat on their back and think ‘oh my goodness I’ve done something awful to my baby’.” Just turn over, you may be able to breathe better that way anyway.
Sometimes you conduct a study, and the results suck, but you still have to report them. That’s what the authors of an influenza safety study found last week, when they discovered an association between miscarriage and flu vaccination. It’s bad enough that this gives more ammo to antivaxxers, but it also sucks because flu vaccines are particularly important for expecting mothers. Flu symptoms can be more severe for this population, and can lead to pre-term births and miscarriages all on their own. Plus, the vaccine is the only way for developing babies to receive long-term flu protection since infants younger than six months can’t receive it. So please, protect yourself, your kids, and the rest of us too.
Last week InsightCity reported on a contraceptive injection for men. Tests showed the drug to be 96% effective at preventing pregnancy. Is 96% effective enough to be trusted?
