The sexual life of couples and their needs during pregnancy receive little attention in practice. The aim of this study was to evaluate an educational intervention delivered to pregnant couples to improve their sexual function and satisfaction. This quasiexperimental study was conducted on 128 couples, allocated into two groups of intervention (group A: couples, group B: pregnant women) and one control group (C). Postintervention, the mean of the total score of sexual function and satisfaction of the couples was significantly higher in the intervention groups compared with the control group (p < 0.05). It seems sexuality education specific for prenatal care would be effective.
