Can You Give Sperm an Advantage?
Q: Can gravity help sperm work their magic?
A: Probably not. Some women think that lying on your back with your hips elevated for 20 minutes after sex will help ensure that every last sperm gets a fighting chance at the prize, but the belief has no scientific foundation, according to Optimizing natural fertility. It can't hurt, though, Dr. Goist says. So why not use the technique as an excuse to get your post-romp cuddle on?
Q: Will lubricants help his sperm reach my egg?
A: Nope. Your cervical mucus moves sperm along quite swimmingly all on its own. Plus, most lubricants can interfere with cervical mucus, alter the pH in your vaginal tract, and kill off even the sturdiest of sperm. In fact, water-based lubricants (like Astroglide, K-Y Jelly, and Touch) inhibit sperm motility in vitro by 60 percent to 100 percent within 60 minutes of incubation, according to a study published in the International Journal of Fertility and Menopausal Studies. If you really need some extra lubrication during sex (a common issue when you're more focused on making babies than making love), sticking with mineral oil, canola oil, or a hydroxyethylcellulose-based lubricant such as Pre-Seed are your best bets, Dr. Brasner says.
