Understanding the beliefs and knowledge related to women's sexuality is important when working with unique religious groups in order to provide culturally appropriate care. An exploratory, descriptive qualitative study generated knowledge, beliefs, and practices related to menstruation, ovulation, and family planning among Low German-speaking (LGS) Mennonite women (n = 38). There is a pervasive silence that surrounds sexuality among this group, who have a limited understanding of the physiological changes they experience. Honoring religious principles and family and community expectations through acceptable female behavior is essential. Adherence to religious principles varies by family but is not shared with the group to avoid disfavor.
