There have been a few studies conducted on couples' sexual behavior during pregnancy and the year postpartum, but those studies contain sampling bias resulting from recruiting volunteers for sex research. The sample for the current research was recruited for a far less sensitive study, and includes data from both mothers and fathers.
A total of 570 pregnant women and 550 of their husbands or partners were recruited and were interviewed on four occasions: (1) at the fifth month of pregnancy (T1); (2) at 1 month postpartum (T2); (3) at 4 months postpartum (T3); and (4) at 12 months postpartum (T4).
Although approximately 90% of couples engaged in sexual intercourse at T1, T3, and T4, only approximately 19% did at T2. On average, couples resumed intercourse at 7 weeks postpartum. At T2 and T3, women who were breastfeeding showed significantly less sexual activity and less sexual satisfaction than women who were not. There were few differences between women who gave birth vaginally and those who were delivered by cesarean section, except that the latter resumed intercourse somewhat earlier.
Practitioners providing family-centered maternity care need to counsel couples about typical patterns of sexuality during pregnancy and postpartum, and about usual patterns during breastfeeding. Accurate information can help couples feel more comfortable during the transition periods before and after childbirth. A discussion of expected changes in sexuality should be routinely introduced by the physician during prenatal care.
关于孕期及产后一年内夫妻性行为的研究较少，但这些研究存在因招募性研究志愿者而导致的抽样偏差。本研究的样本是为一项敏感性低得多的研究招募的，包括来自母亲和父亲的数据。
共招募了570名孕妇及其550名丈夫或伴侣，并在四个时间点进行访谈：（1）孕期第五个月（T1）；（2）产后1个月（T2）；（3）产后4个月（T3）；（4）产后12个月（T4）。
虽然约90%的夫妻在T1、T3和T4时进行了性交，但在T2时只有约19%的夫妻进行了性交。平均而言，夫妻在产后7周恢复性交。在T2和T3时，母乳喂养的女性的性活动和性满意度明显低于未母乳喂养的女性。顺产女性和剖宫产女性之间几乎没有差异，只是剖宫产女性恢复性交的时间稍早一些。
提供以家庭为中心的孕产护理的从业者需要就孕期和产后的典型性行为模式以及母乳喂养期间的常见模式向夫妻提供咨询。准确的信息可以帮助夫妻在分娩前后的过渡时期感觉更舒适。医生在产前护理期间应常规性地讨论性行为的预期变化。
