The first sexual intercourse after childbirth may be challenging for women, especially if the birth resulted in injuries in the genital area. The purpose of this study was to investigate whether or not tears in the vagina, perineum, sphincter ani, or rectum hindered sexual intercourse during the year after childbirth.
We obtained information from 2,490 women in a population-based cohort identified at antenatal care. Information about first sexual intercourse was collected by means of a questionnaire sent 1 year after birth to the women and about women's tears reported in the population-based Swedish Medical Birth Register.
Adjusted relative risks with 95 percent confidence intervals for not having had sexual intercourse within 3 and 6 months, respectively, after childbirth were 1.5 (95% CI 1.2-1.8) and 1.6 (95% CI 1.2-2.3) for tears in the vagina, 1.4 (95% CI 1.1-1.6) and 1.5 (95% CI 1.1-2.1) for tears in the perineum, and 2.1 (95% CI 1.4-3.1) and 2.2 (95% CI 1.1-4.6) for tears in the sphincter ani and rectum. No statistically significant differences were found at 1-year follow-up. No associations between episiotomy and delay in resuming intercourse were found after adjusting the relative risks.
Tears in the vagina, perineum, sphincter ani, or rectum are associated with a delay in women's resumption of sexual intercourse 6 months after childbirth in Sweden.
产后首次性交对女性来说可能具有挑战性，尤其是如果分娩导致生殖器区域受伤。本研究的目的是调查阴道、会阴、肛门括约肌或直肠撕裂是否会在产后一年内妨碍性交。
我们从产前护理中确定的一个基于人群的队列中的2490名女性那里获取信息。关于首次性交的信息是通过在产后1年向女性发送问卷收集的，以及关于在瑞典基于人群的医学出生登记册中报告的女性撕裂情况。
分别在产后3个月和6个月内未进行性交的调整后相对风险及95%置信区间，阴道撕裂者为1.5（95%CI 1.2 - 1.8）和1.6（95%CI 1.2 - 2.3），会阴撕裂者为1.4（95%CI 1.1 - 1.6）和1.5（95%CI 1.1 - 2.1），肛门括约肌和直肠撕裂者为2.1（95%CI 1.4 - 3.1）和2.2（95%CI 1.1 - 4.6）。在1年随访时未发现统计学上的显著差异。调整相对风险后，未发现会阴切开术与恢复性交延迟之间存在关联。
在瑞典，阴道、会阴、肛门括约肌或直肠撕裂与女性产后6个月恢复性交延迟有关。
