Objectives: Sexual life may have some changes during pregnancy. Owing to negative attitudes toward having sex, unpleasant feeling and fear for some factors, women might avoid vaginal intercourse during pregnancy. We performed a systematic review aiming at understanding the frequency of vaginal intercourse in pregnancy.
Materials and Methods: Comprehensive literature search was conducted to search for relevant articles published, including observational studies (like cross-sectional and cohort studies) that certainly determined mean frequency of vaginal sex throughout pregnancy from December 1990 to April 2018. In this regard, we searched online international databases, including ISI, PubMed, Scopus, Cochrane and Google Scholar. The databases were checked for relevant articles by two authors independently. Duplicate articles were removed by using EndNote X7 Reference Manager. The analysis of the results was conducted using RevMan 5.3 software, and P<0.05 was considered significant.
Results: Totally, we found 13 articles after removing duplicate articles, and irrelevant articles were excluded based on having mean frequency of vaginal intercourse during pregnancy. The range of vaginal intercourse frequency was different from 6.01 – 21 times monthly pre pregnancy, 3.67 - 9.87 times monthly in the first trimester, 2.78 - 7.21 times monthly in the second trimester and 1.35 - 5.9 times monthly in the third trimester.
Five studies of the 13 selected articles reporting the standard deviation in addition to mean were entered our meta-analysis. Frequency of vaginal intercourse was obtained 7.75 (7.13-8.38) times monthly prior to pregnancy, 4.16 (3.86-4.46) times in the first trimester, 6.37 (5.60-7.14) times monthly in the second trimester and 1.81 (1.49-2.13) times monthly in the third trimester.
Conclusions: Thus, vaginal intercourse frequency decreased in the first trimester, then increased in the second trimester, and a sharp drop was observed between the second and third trimesters of pregnancy.
