Heavy Menstrual Bleeding: A Common yet Often Overlooked Health Issue

Heavy menstrual bleeding (HMB) affects a significant number of women, making it more common than conditions like asthma and diabetes. Despite its prevalence, many women endure this condition for years before seeking help, often missing an average of 3.6 weeks of work annually, which incurs a substantial economic burden estimated at around $94 billion in the U.S. alone. Each minute, a woman in the United States requires a blood transfusion due to HMB, highlighting the severity and urgency of addressing this health concern.

Unfortunately, the causes of heavy menstrual bleeding are not yet fully understood, making diagnosis and treatment challenging. To bridge this gap, researchers led by Donald Ingber at Harvard's Wyss Institute are pioneering the development of a groundbreaking organ-on-a-chip model of menstruation. Funded by Wellcome Leap’s $50 million Missed Vital Sign program, this innovative approach aims to drastically reduce the time needed for women to receive effective treatment—from an average of five years down to roughly five months.

Organ-on-a-chip technology involves creating a living, three-dimensional model of a specific organ or tissue, allowing scientists to study its functions in a controlled environment. Ingber’s team has already developed chips mimicking the lungs, intestines, cervix, vagina, and fallopian tubes. These models enable researchers to manipulate various parameters, such as genetic mutations, oxygen levels, microbiomic conditions, and inflammation, to understand their roles in menstrual health.

The menstrual organ-on-a-chip system is designed to overcome limitations of traditional animal models, especially since mice do not naturally menstruate, instead undergoing an estrous cycle. This biological difference has historically hindered research into human menstruation and associated disorders. The new chip aims to provide more accurate insights into the mechanisms of heavy menstrual bleeding, which is a key step toward better diagnostics and personalized treatments.

By isolating specific functions of the reproductive system, the platform allows for detailed analysis of tissue responses to different stimuli, mimicking movements like breathing and peristalsis through mechanical forces. Although the technology simplifies complex organ functions, it offers substantial advantages over animal models, fostering faster research and potential breakthroughs.

This innovative work is part of larger efforts by the Wyss Institute to address disparities in women’s health research. The development of menstruation-specific models promises to illuminate understudied aspects of reproductive health, ultimately leading to improved therapies and better health outcomes for women worldwide.
