Rowe, Elizabeth Jane, Temple U., Philadelphia, PA - To aid research on 'The Role of the Progesterone Receptor in the Menstrual Cycle,' supervised by Dr. L. Christie Rockwell

ELIZABETH JANE ROWE, then a student at Temple University, Philadelphia, Pennsylvania, was awarded a grant in May 2008, to aid research on 'The Role of the Progesterone Receptor in the Menstrual Cycle,' supervised by Dr. L. Christie Rockwell. Much of the work in Physical Anthropology related to variation in women's reproductive function has been heavily focused on evolutionary models to explain the responsiveness of ovarian steroid production to ecological conditions. Underlying functionally significant, genetic variation that also likely impacts reproductive phenotypes has seldom been investigated. This project addressed this problem by investigating the impact of a common, functionally significant variant of the progesterone receptor gene on uterine function and the menstrual cycle among women in the Philadelphia area. Women who carried the variant differed from women who did not with regard to menstrual cycle characteristics. Furthermore, the variant was found to modify the impact of life history and ecological variables on both uterine function and the menstrual cycle. These findings indicate that genetic variation should be considered in future models for women's reproduction in Physical Anthropology. Additionally, uterine function and menstrual cycle characteristics did not reflect ovarian hormone levels, but instead were significantly predicted by ecological variables that indicated energetic status. These findings, coupled with results of other work, indicate that the uterus responds directly to environmental cues, and therefore suggest that it plays an active role in the maternal decision to commit resources to gestation.
