Population Council Research that makes a difference

Régine Sitruk-Ware, M.D.

Distinguished Scientist

Régine L. Sitruk-Ware is a reproductive endocrinologist and holds the position of distinguished scientist at the Population Council’s Center for Biomedical Research. She supervises basic research in reproductive biology as well as preclinical research and clinical development of new molecules designed for reproductive health care in men and women suitable for use in developing countries. Prior to joining the Council, she had an academic career in Paris, France, and then an international career in industry in research and development. She taught and conducted clinical research in reproductive endocrinology at the University of Paris for ten years. From 1983 to 1989 she was a member of the International Committee for Contraception Research (ICCR), established by the Population Council in 1970. Sitruk-Ware became chairperson of the ICCR in January 2007. She is a member of several national and international medical societies. She has been a founding member of the International Menopause Society and a member of its executive committee for several terms and is presently the general secretary elect of that society. She is a member of the Expert Group on Hormonal Contraception of the European Society for Contraception. She is also the program director and principal investigator of a National Institutes of Health (NIH) Center grant from the National Institute of Child Health and Human Development.

Sitruk-Ware has written eight books and over 250 articles and reviews, mostly dealing with men and women’s health care issues. She served as adviser to several ad hoc committees of the World Health Organization, the NIH, and the Institute of Medicine of the US National Academy of Sciences. She received her medical doctorate at the University of Paris in France and is currently an adjunct professor at Rockefeller University.
