A special feature in the journal Science dedicates its latest issue to analyzing gaps in women’s health, highlighting that millions of women suffer disproportionately from chronic pain due to hormonal and chromosomal factors.

The publication notes that women’s health has traditionally taken a back seat in medical research; when it has taken center stage, studies have focused primarily on reproduction.

Yevgenia Nusinovich, a senior editor at Science, points out in an analysis article that it is becoming increasingly clear that women’s health and sex-related biological differences extend far beyond reproduction, affecting individuals throughout their lives and across various medical conditions.

Four review articles examine research aimed at addressing significant gaps in women’s health, according to the publication. These papers cover topics ranging from sex-specific mechanisms of chronic pain to the roles of sex chromosomes, menopause, and the immune system in women’s health.

One of the articles, led by the University of California, San Francisco (USA), focuses on sex-specific mechanisms of chronic pain. The authors note that it has long been known—for decades—that women, especially younger ones, are disproportionately affected by painful disorders such as irritable bowel syndrome, endometriosis, menstrual migraines, fibromyalgia, osteoarthritis, and neuropathic pain, all of which diminish quality of life.

The inclusion of sex as a biological variable in 2016 has begun to transform this field, revealing sex-specific pathways that initiate, amplify, and resolve pain. The article summarizes advances in the field of visceral and somatic pain, highlighting that the close relationship between hormonal fluctuations and symptoms is a common feature of many types of pain experienced by women.

Immune-neural interactions, the gut microbiota, and endogenous analgesic circuits also play a role. Although a growing body of research is beginning to unravel how hormonal signals interact within the female body, significant gaps remain between the widespread burden of pain among women and scientific efforts to understand and treat it.

Women are eagerly awaiting concrete answers that could help eliminate the common it’s “all in your head” attitude toward their conditions and shorten the long wait between symptom onset and diagnosis or treatment, the authors note.

Another article, led by the same university, gathers evidence showing that X and Y chromosomes not only determine biological sex but also influence the risk of developing diseases—including cancer—independently of hormones. Health differences between men and women have long been attributed primarily to sex hormones, such as estrogen and testosterone.

The analysis shows that X and Y chromosomes contain genetic instructions determining how cells age and how the body defends itself against major diseases, noted Dan Theodorescu, a researcher at the University of Arizona (USA) and one of the paper’s authors.

Research on menopause is the focus of another article, which points out that the field has historically been underfunded, despite its enormous impact on half the population and on nearly 40% of a woman’s life. That research requires a fundamental rethink, shifting from a single, generalized view to a precision medicine approach that accounts for differences in symptoms, onset, genetics, and hormonal treatments.

Reducing menopause to mere aging does women a disservice, note the authors, led by the Oklahoma Medical Research Foundation (USA).

Another article focuses on the role of the immune system in preparing the body for pregnancy—a process that triggers one of the most prolonged periods of physiological remodeling in adult life. Although 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 can influence health long after pregnancy.

Finally, the special feature examines how the ovaries influence health after menopause, as growing evidence suggests they remain biologically active for decades beyond that period.
