Lifestyle and Dietary Effects on Male and Female Reproduction

Dr. Mumford’s research interests focus on the relation between diet and the biologic capacity for reproduction irrespective of pregnancy intentions. Despite diet’s importance for human survival, its relation to fecundity remains an understudied area with many critical data gaps. Dr. Mumford has been an integral investigator on two longitudinal epidemiologic studies: the BioCycle Study and the Effects of Aspirin on Gestation and Reproduction (EAGeR) Trial. Her responsibilities have included leadership roles in the analysis of diet in relation to a spectrum of reproductive outcomes (e.g., hormonal profiles, menses, ovulation) in BioCycle, and in the development of the nutritional component for the EAGeR Trial. Dr. Mumford also serves as a principal investigator in the Folic Acid and Zinc Supplementation Trial (FAZST), which seeks to determine if dietary supplementation improves semen quality. Overall, her work seeks to elucidate the complex relationships between diet, metabolism, and determinants of fertility.


Sunni Mumford, Ph.D., is an Earl Stadtman Investigator in the Epidemiology Branch of the Division of Intramural Population Health Research. Dr. Mumford earned her doctoral degree in epidemiology from the Gillings School of Global Public Health, University of North Carolina, Chapel Hill in 2009. This training was preceded by a Master’s of Science degree in biostatistics from the Harvard University School of Public Health and a Bachelor’s of Science degree in statistics from the College of Sciences at the Utah State University in 2006 and 2002, respectively.
