The effect of coitus on precipitation of preterm labor was studied prospectively in 126 women with twin pregnancies. All of the women attended a special antenatal clinic in a tertiary referral center and were questioned about the frequency of coitus. Of the participants, 40% reported coitus early in the third trimester; the rate decreased to 24% by 36 weeks' gestation. There were no significant differences in the frequency of positive responses between those who went into labor before term when contrasted with those who were delivered of infants at term. The data indicate that coitus is not an important precipitant of preterm labor in this high-risk group and that coitus need not be discouraged in women with twin pregnancies.
对126例双胎妊娠妇女进行前瞻性研究，以探讨性交对早产的影响。所有妇女均就诊于一家三级转诊中心的特殊产前诊所，并被询问性交频率。在参与者中，40%报告在妊娠晚期早期有性交；到妊娠36周时，这一比例降至24%。与足月分娩婴儿的妇女相比，早产妇女的阳性反应频率没有显著差异。数据表明，在这个高危人群中，性交不是早产的重要诱发因素，双胎妊娠妇女无需避免性交。
