Research Summary

The Fertility and Reproductive Health Group is led by Anne Marie Z. Jukic, Ph.D., and focuses on factors that influence reproductive function (e.g., follicle development and menstrual cycles), conception, implantation, placental development, and pregnancy outcomes. Given the financial and emotional burden of subfertility and pregnancy loss, this research has broad and immediate public health relevance.

Menstrual cycles are an indicator of general health and menstrual cycle disturbances may predict difficulties in conceiving a pregnancy. Moreover, women with menstrual cycle irregularities may be treated with hormonal contraception, and there are currently no alternatives for women who desire non-hormonal options to regulate their cycles.

Vitamin D is known for its role in bone health, but its role in reproduction is a flourishing area of research. Lower levels of 25-hydroxyvitamin D (25OHD) (what clinicians measure to identify vitamin D deficiency) have been associated with lower pregnancy conception rates. Low levels of vitamin D are common in the U.S., especially among African-American and Hispanic women. The Fertility and Reproductive Health Group has published several studies that found increased risk of prolonged or irregular menstrual cycles and delayed ovulation with lower levels of 25OHD. Importantly, in two of these studies either all, or a majority of the participants were African-American. Jukic recently received a Bench-to-Bedside award to support a clinical trial that further investigates the role of vitamin D in menstrual cycles and menstrual cycle hormones. The Fertility and Reproductive Health Group is also collaborating with Francesco DeMayo, Ph.D., in RDBL on an NIEHS Internal Opportunity Award (NIOA) to investigate the biological pathways that are altered by vitamin D deficiency and repletion in a mouse model.

Other areas of ongoing research in the Fertility and Reproductive Health Group include the correlations between vitamin D and metals levels, air pollution, fertility and pregnancy loss, microRNA in early pregnancy, and methodological challenges in reproductive epidemiology.

Jukic received a B.S. from the University of Notre Dame, an M.S.P.H. from Emory University, and a Ph.D. in epidemiology from the University of North Carolina at Chapel Hill. She completed a postdoctoral fellowship at NIEHS and was an Assistant Professor at the Yale School of Public Health before joining NIEHS as a Principal Investigator.
