Menopause comes with aging, marking the end of menstrual cycles. Even though it’s a significant aspect of aging that entails health implications, it often gets overlooked in research: a recent perspective in Nature Aging reveals that 99% of studies on the biology of aging fail to adequately consider menopause. This tremendous gap in research has serious implications for women’s health care, leading to a lack of understanding of age-related issues affecting females. 

On average, female individuals will live about a third of their lives in a postmenopausal state. However, despite menopause’s pivotal role in female aging, there is a lack of reliable animal models of this transition, hindering the ability to study its effects on health and disease progression comprehensively. 

This oversight also extends to other significant events in female life cycles, such as pregnancy, childbirth, and breastfeeding. These experiences can bring long-term health implications, yet they are often ignored in preclinical studies, which are predominantly based in male animal models. This disparity undermines the understanding of how these events influence aging and disease outcomes in women. 

The consequences of this research gap are glaring in clinical practice, where healthcare providers struggle to effectively treat age-related diseases in females: women tend to experience more physical and cognitive declines as they age, yet current approaches often fail to address these gender-specific nuances. From heart attacks to osteoarthritis, the disparities in diagnosis and treatment stress the urgent need for more inclusive research practices. 

Recognizing the limitations that exist in current research models and prioritizing the inclusion of menopause and other female-specific traits in studies are crucial first steps in addressing this gap. Increased collaboration among aging researchers and dedicated funding for gender-inclusive research are also essential to advancing the understanding of aging and improving health outcomes for women.
