Introduction: Both, menstruation and sexual activity, relate the same intimate part of the woman's body - the genitals. Thus, they are likely to be psychologically linked. Although menstruation is a part of a natural, reproductive process, it bears a strong cultural taboo. Views on menstruation and the menstruating woman remain negative. Purpose: To acknowledge men's various perspectives on sexuality during menstruation. Methods: In the theoretical part of diploma work, a descriptive method was used. Basic literature was found in textbooks and books, published between 1984 and 2018. Scientific articles were retrieved from the databases PubMed, ScienceDirect and SpringerLink with keywords menstruation, men, society, perception, linked with Boolean operator AND. Included articles were published between 1990 and 2018, due to the search for changes in attitudes towards menstruation, they were written in the Slovenian or the English language, with free access to full content, and offered suitable and relevant content. Article quality was evaluated based on a four-level scale. 15 articles were included altogether. In the empirical part of the diploma work, a causal nonexperimental method was used. A survey questionnaire with 20 questions was designed as a research instrument on the web portal 1KA and shared on various social networks. The research sample consisted of men who had already had sexual intercourse. Results: 539 questionnaires were adequately completed. 56 % of participants have vaginal intercourse during woman's menstruation and more than a half of these believe it to be a part of healthy adult sexuality. Among participants who decides against sexual intercourse during woman's menstruation, it is a common opinion that women need other ways of expressing love and affection during that time. Discussion and conclusion: Most participants in the present research have positive attitudes towards menstruation and a woman during menstruation, whereas in older studies, negative attitudes prevail. Received data can imply a more open relationship of men towards menstruation compared to the past but the results cannot be generalised due to some methodological weaknesses of the research.
