For centuries women have tried to induce their labors with such "natural" methods as eating hot spicy foods, taking castor oil, or giving themselves enemas. Unfortunately, none of these "folk remedies," often passed from one generation to the next, are likely to start labor unless the woman's body is ready for labor to begin. Labor is triggered by a shift in several pregnancy hormones. The cervix needs to be soft (ripe), thin (effaced), and ready to open (dilate). Unless these factors are in place, no amount of walking will cause labor to begin. Having sexual intercourse can help initiate labor if the things mentioned above have occurred, because the male seminal fluid contains prostaglandins that stimulate uterine contractions. And when the woman experiences an orgasm her uterus contracts as well. So patience is the key. Mother Nature knows when the time is best for your baby to make an entrance!
