Benefits of physical activity on reproductive health functions among polycystic ovarian syndrome women: A systematic review

Abstract

Abstract Background Polycystic ovary syndrome (PCOS) is amongst the predominant endocrine disorders of reproductive-aged women. The prevalence of PCOS has been estimated at around 6–26%, affecting 105 million worldwide. This systematic review aimed to synthesize the evidence on the effects of physical activity on reproductive health functions among PCOS women. Methods The systematic review includes randomization-controlled trials (RCTs) on physical exercise and reproductive functions among women with PCOS. Studies in English language published between January 2010 and December 2020 were identified via PubMed. A combination of medical subject headings terms of physical activity, exercise, menstrual cycle, hyperandrogenism, reproductive hormone, hirsutism, and PCOS were used. Results Overall, six RCTs were included in this systematic review. The studies investigated interventions of physical activity of any intensity and volume and measured reproductive functions, hormonal and menstrual improvement. The inclusion of physical activity alone or in a combination with other therapeutic interventions improved the reproductive outcomes. Conclusion The reproductive functions of PCOS women can be improved with physical activity. Furthermore, physical activity can also reduce infertility, as well as social and psychological stress among women. PROSPERO Systematic review registration: CRD42020213732
