OBJECTIVE: This study was planned to determine the sexual myths of men during pregnancy. MATERIAL and METHODS: The descriptive study was conducted between December 2018 and January 2019 with 134 men who met the research criteria in two training and research hospitals in Istanbul. Research data were collected by using the information form prepared by the researchers after the literature review and ‘Sexual Myths Scale’. RESULTS: Of the 133 fathers who participated in the study, 50.4% were 19–31 years of age. In the first quarter of the year, a business majority spent a long period of life in the province (87.2%). Almost half of the men (47.4%) said that they learned the first sexual information online, 91.0% stated that sexual intercourse may occur during pregnancy and only 17.3 thought that sexual intercourse could harm the baby. Although men had sexual intercourse with their spouse during pregnancy, 93% thought that sexual intercourse during pregnancy was a shame. Almost all of the males (99.2%) stated that normal birth would not affect sexual life and would not adversely affect sexual life in the future. When the Sexual Myths Scale was examined; every man should know how to give pleasure to his wife (96.2%), if couples love each other knows that they also enjoy sex (96.2%). There was no significant difference between most of the myths and education, family type, monthly income and long-term place of residence (p≥0.05). However, higher educated and long-lived men had a lower rate of confirmation of myths. CONCLUSION: It was determined that the sexual myths of the men who participated in the study were high in pregnancy. It was found that the rate of male belief in sexual myths was related to education level and place of residence.
