When you've been pregnant for what feels like forever, you're willing to do just about anything to move things along. Once you've tried all the recipes for labor-inducing eggplant parmesan, walked until you feel like your legs are going to fall off, and chugged that tea that your great aunt told you will surely bring on labor, you're desperate. Time to pull out the big guns and get naked. You've heard that having sex can induce labor, but what works best? While there's no golden bullet, it's possible that these sex positions can soften your cervix and help you reach your goal — or at least reach your O.
But it's worth noting that there is not a lot of scientific evidence available that supports the idea that certain sex positions will work better than others to ripen your cervix and induce labor. However, there is a lot of anecdotal evidence and passed information around the practice. The Academy of American Family Physicians (AAFP) research found that "if the cervix is unfavorable, a successful vaginal birth is less likely." But they also noted that while it's uncertain if it actually works, there is a reason to be hopeful that having sex could possibly help induce labor during the late stages of pregnancy. Apparently the stimulatory aspects of sex "result in a local release of prostaglandins. Female orgasms have been shown to include uterine contractions, and human semen contains prostaglandins, which are responsible for cervical ripening." So, if it's going to work, these sex positions to soften your cervix will be the ones that stimulate the most and deliver the semen to the cervix — oral sex is clearly not the winner in this scenario.
