Introduction: Sexuality is an important part of healthy living. Besides its primary purpose of progeny conservation, it also presents emotional connection between partners needed for successful satisfaction of sexual demands. For sexual health, the state of well-being, which allows men participating and enjoying at sexual activities, is of utmost importance. Pregnancy and postpartum period are the periods of many intense changes which affect sexuality of both, a woman and her spouse. Purpose: The purpose of the degree paper is to present sexual experiences of men during their partners’ pregnancy and in the period of a year after childbirth, as well as to explore the changes which occur during these two periods. Methods: The descriptive method is used in the theoretical part of the degree paper, whereas in the second part, the descriptive casual non-experimental method of empirical research is applied. The research approach is based on quantitative research. The data was gathered in ten days with a survey questionnaire. The survey was anonymous, and it included men whose partners were from 6 weeks up to twelve months postpartum. Results: In the research, the men were comparing sexual satisfaction, desire, and the frequency of sexual intercourses before their partners’ pregnancy, during it, as well as in postpartum period. 66.2 % of them reported equal satisfaction during pregnancy and 67.9 % in postpartum period. 64.6 % assessed sexual desire equal during pregnancy and 67.7 % in postpartum period. The frequency of sexual intercourses decreased to 61.8 % during pregnancy and 59.4 % postpartum. Discussion: Although the frequency of sexual intercourses decreases during pregnancy and in postpartum period, men are satisfied with sexual activities in both periods. They find active sex life very important. In the period after childbirth, they give priority to childcare, communication with their partner, emotional connection with their partner, and exchanging tenderness. Sexual demands are therefore not paramount in the first few months after the birth of a child. Conclusion: The research enabled us to get an insight into men’s satisfaction with their partners’ sexual relationship during pregnancy and in postpartum period. Considering that a quarter of men in our research claimed lack of information regarding sexuality in the period after childbirth, each couple needs to be treated individually in preparation for parenthood, including information concerning sexual activities during pregnancy and after childbirth.
