Institute Activities and Advances
The NICHD conducts and supports research to learn more about menstrual irregularities. The following organizational units address issues related to menstruation and the causes and effects of menstrual irregularities.
- The Division of Intramural Population Health Research (DIPHR) is interested in statistical methodology, comparative etiologies, and the health endpoints needed to identify mechanisms, at-risk groups, and interventions. Some of these activities include:
- Gaining a better understanding of the intricate relationship between hormone levels (estrogen, progesterone, luteinizing hormone, etc.) and oxidative stress during the menstrual cycle. Data from the BioCycle Study are helping researchers examine the intracycle variation of oxidative stress, reproductive hormones, inflammation, and metabolic biomarkers; the relation between hormone levels and oxidative stress during the menstrual cycle in premenopausal women; and the influence of external factors (such as dietary intake, cigarette smoking, alcohol consumption, and exercise) on oxidative stress and hormone levels.
- Developing various approaches to modeling menstrual cycle function. The menstrual cycle is a complex process that involves multiple hormones regulated by feedback mechanisms. To describe the factors associated with menstrual cycle function and inform women's health research, the DIPHR is developing statistical models to answer questions like:
- What is the "typical" menstrual cycle pattern in a population of women?
- How do lifestyle factors that vary between women (e.g., dietary intake, physical activity, stress) affect a typical menstrual cycle?
- How does the variation in menstrual cycle function differ between women and across consecutive cycles on the same woman?
- What is the inter-relationship between multiple hormones across the menstrual cycle?
- Determining the relationships between endometriosis and environmental chemicals, lifestyle, and medical history. The Endometriosis: Natural History, Diagnosis, and Outcomes (ENDO) Study is following 625 women undergoing surgery for this disorder, which often involves irregular, painful menstruation. The study compares these women's medical findings, life characteristics, and other factors to those of women of similar age and location who don't have endometriosis.
- Various components of the Division of Intramural Research study aspects of menstruation and menstrual irregularities. For example:
- Components of the Division of Extramural Research also support studies on normal menstruation and conditions related to menstrual irregularities.
Other Activities and Advances
- Through the FI Branch, the NICHD supports the following research networks and centers programs that contribute to understanding menstrual irregularities within the context of fertility and infertility:
- The GHDB supports the Women's Reproductive Health Research (WRHR) Career Development Program, which allows obstetricians/gynecologists who have recently completed clinical training to enhance their education and experience with basic, translational, and clinical research on women's health topics, including normal menstruation and menstrual irregularities.
- Between 2010 and 2012, the Institute was also involved in the following meetings related to menstruation and menstrual irregularities:
