Ratings of sexual behaviour and feelings were obtained regularly from subjects of a longitudinal study of psychiatric status and psychological change in pregnancy and the first postnatal year. The results are consistent with previous research, showing a reduction in frequency of sexual intercourse and in interest and satisfaction with sex over the course of pregnancy. Coitus was resumed after childbirth within six weeks by nearly 60% of women, and within three months by eighty. In most cases, ratings of interest in and satisfaction with sex also returned to early pregnancy levels by three months postnatal. Despite clear trends in the group as a whole there was considerable individual variation, investigated using tests of association with measures of subject characteristics and psychological status.
在一项关于孕期及产后第一年精神状态和心理变化的纵向研究中，定期对研究对象的性行为和感受进行评分。研究结果与先前的研究一致，表明在孕期性交频率、对性的兴趣和满意度均有所下降。近60%的女性在产后六周内恢复性交，80%的女性在三个月内恢复。在大多数情况下，对性的兴趣和满意度评分在产后三个月也恢复到了孕早期的水平。尽管总体趋势明显，但个体差异很大，研究人员通过与研究对象特征及心理状态测量指标的关联测试对其进行了调查。
