Objective. This study compares several parameters of sexual life and course of labor in women with planned and unplanned pregnancy. Methods. 339 primiparas participated in our study; they filled in a questionnaire concerning their sexual life during pregnancy on the second or third day after the delivery. One question also stressed planning of pregnancy. 246 women (i.e., 72.6%) indicated planned pregnancy, 93 pregnancies (i.e., 27.4%) were not planned. Results. Significant decrease of coital activity and number of orgasms and increase of sexual dysfunctions were observed in the whole study group during pregnancy. Significant differences between women with planned and unplanned pregnancy were observed only in frequency of vaginal dryness and pelvic pain. Conclusions. According to the results of this study, unplanned pregnancy has no adverse effect on parameters of the labor. The equal rate of partner's presence at delivery shows a high involvement of the partners of unmarried women.
