The editors of this Special Issue, including Science Senior Editor Yevgenia Nusinovich and colleagues, emphasize that the current scientific consensus is shifting rapidly. It is becoming increasingly clear that women’s health cannot be isolated to the reproductive years or the mechanics of pregnancy. Instead, sex-specific biological mechanisms influence health outcomes from early childhood through late adulthood. This broader perspective acknowledges that the female body operates under distinct hormonal, immune, and metabolic constraints that require dedicated investigation. By moving beyond the traditional focus on reproduction, researchers are beginning to map a more accurate and comprehensive landscape of female biology, one that recognizes the profound impact of sex on disease progression, treatment response, and overall well-being.

One of the most pressing areas of inquiry highlighted in the issue is the disproportionate burden of pain disorders experienced by women. It has long been recognized that millions of women, particularly younger demographics, suffer from functional pain disorders at roughly twice the rate of men, with some conditions showing even greater disparities. Persistent pain is especially debilitating when it affects the pelvis, where disorders involving the gut, bladder, and reproductive organs, such as irritable bowel syndrome, endometriosis, and vulvodynia, can produce unpredictable and severe symptoms. Archana Venkataraman and colleagues synthesize recent advances in understanding these conditions, focusing on the intricate roles of sex hormones, immune-neural interactions, the gut microbiome, and endogenous analgesic pathways. Their analysis suggests that fluctuations in ovarian hormones beginning at puberty are a major contributor to these sex-specific pain experiences, yet major gaps remain between the widespread burden of pain among women and the scientific efforts to understand and treat it effectively.

The authors of this Review express a sense of urgency regarding the lack of concrete answers for women suffering from chronic pain. They note that women are desperately waiting for scientific clarity that might help eliminate the common dismissive approach of labeling their illnesses as “all in your head.” Furthermore, there is a critical need to shorten the long wait between the onset of symptoms and the provision of diagnosis and treatment. The goal is to ultimately provide mechanism-based strategies for disease treatment that address the root biological causes rather than merely managing symptoms. This shift in focus from symptom management to mechanistic understanding represents a significant step forward in the field of women’s health research, aiming to validate patient experiences with rigorous scientific evidence.

Another critical area of focus is menopause, a transition that has historically been underfunded and understudied despite its enormous impact on half of the human population and nearly forty percent of a woman’s lifespan. Larua Gravelsins and colleagues argue in a second Review that menopause research needs a major rethink, shifting from a one-size-fits-all view of the transition to a precision-medicine approach. This new framework accounts for differences in symptoms, timing, genetics, and hormone treatments, recognizing that menopause is not a uniform experience. The authors suggest that this shift could help address the persistent gaps in understanding menopause and menopause hormone therapy, providing more tailored and effective care for women navigating this complex biological change.

Gravelsins and colleagues contend that diminishing menopause to “just aging” is a disservice to women. They emphasize that menopause is a full-body, hormonally driven change that, like other endogenous hormonal transitions, affects individuals differently based on their individual biology and life experience. By adopting a precision-medicine approach, researchers can better understand the diverse manifestations of menopause and develop targeted interventions. This perspective challenges the traditional view of menopause as a simple decline in function, instead framing it as a complex physiological transition that requires nuanced scientific attention and personalized medical care.

In a third Review, Dan Corral and Yasmine Belkaid highlight the emerging research surrounding the immune system’s role in preparing a mother’s body for pregnancy. Pregnancy triggers one of the most extensive periods of physiological remodeling in adult life, requiring coordinated changes across nearly every maternal organ. While these changes have traditionally been attributed largely to hormones, new research shows that the immune system actively directs this remodeling, reprogramming maternal tissues in ways that may influence health well beyond pregnancy. This discovery underscores the importance of the immune system in shaping the maternal environment and highlights the need for further investigation into the mechanisms underlying this transformation, which have historically been understudied.

The final Review by Dena Dubal and colleagues examines how XX and XY chromosomes influence aging and diseases, including neurological, immune, cancer, and cardiometabolic disorders. According to the authors, the collective findings from these studies emphasize the importance of integrating sex chromosome biology into precision medicine. This has important implications for future therapeutics and clinical trial design, suggesting that sex-specific genetic factors play a crucial role in disease development and progression. By understanding how sex chromosomes influence health and disease, researchers can develop more effective and targeted treatments that account for the biological differences between men and women.

In a Perspective, Michael Stout and Francesca Duncan discuss how the ovaries influence health after menopause. The postmenopausal ovary has long been viewed as a largely dormant organ once its reproductive function ends, but growing evidence suggests it remains biologically active for decades after menopause. Determining the ovary’s postmenopausal functions, and whether removing it after menopause affects long-term health, will require further research. This perspective challenges the traditional view of the ovary as a purely reproductive organ and highlights its potential role in maintaining overall health and well-being in postmenopausal women.

This Special Issue of Science represents a pivotal moment in the field of women’s health research. By highlighting the critical gaps in current knowledge and advocating for a more comprehensive and inclusive approach to scientific investigation, these articles aim to drive significant changes in how women’s health is studied and treated. The emphasis on sex-dependent biological differences, precision medicine, and the long-term impacts of hormonal transitions underscores the need for continued investment and innovation in this field. As researchers continue to uncover the complex mechanisms underlying women’s health, the potential for improved outcomes and more effective treatments becomes increasingly clear, paving the way for a future where women’s health is understood and addressed with the same rigor and attention as men’s health.
