ABSTRACT Background There is no formal sexual and reproductive health (SRH) education currently offered in Saudi Arabia. Lack of knowledge and misconceptions are evident among Saudi women, which can lead to negative sexual and reproductive experiences. The aim of this study is to explore Saudi women's SRH knowledge, perceptions and experiences. Methods Qualitative semi-structured interviews with Saudi women were conducted. Interviews took place in a public hospital in Riyadh, Saudi Arabia. Interviews were conducted in Arabic, recorded and transcribed verbatim, to allow for thematic analysis of the data. The following themes were identified: experience with menarche, deep-rooted negative views towards sex, difficulty discussing SRH topics, knowledge of sex and reproduction, generational gap, sources of SRH information and the role of the mother. Results A total of 28 women, both married and unmarried, aged 20–50 years were interviewed. A profound lack of SRH knowledge was observed among Saudi women which contributed greatly to negative experiences both in childhood and adulthood. Lack of knowledge about menstruation often caused emotional distress for young girls, and menarche was associated with bad memories and negative emotions. Lack of knowledge about sexual intercourse and the deep-rooted negative views towards sex were linked with physical and psychological issues for women. Women rarely received information from their parents or teachers and preferred the internet for their SRH information. Conclusion There is a substantial unmet need for SRH education for women in Saudi Arabia. It is our recommendation that SRH education should be tailored to meet Saudi women's unique needs, while understanding specific socio-cultural barriers to SRH education and discussions. Research and policy efforts should be directed towards regulating and producing evidence-based health information on the internet, particularly Arabic language websites.
