Dr. Wright is a double-board-certified orthopedic sports surgeon and researcher whose work provides a key diagnostic framework for the book. As an author and public educator on active aging, she applies a performance medicine lens to menopause, highlighting estrogen’s profound effects on the musculoskeletal system. Her significance lies in naming the “musculoskeletal syndrome of menopause” (MSM), a clinical construct that links widespread pain, strength loss, and injury risk directly to hormonal changes, thereby validating symptoms that are often dismissed, misdiagnosed as fibromyalgia, or considered to be “just aging.”

By coining the term MSM, Wright gives clinicians and patients a unified explanation for the diffuse joint pain, tendon issues, and functional decline that many women experience in midlife. Haver presents this as “groundbreaking work” that helps broaden the understanding of perimenopause beyond hot flashes and gynecological symptoms. Wright’s methodology involves synthesizing evidence from orthopedics, sports medicine, and menopause research to demonstrate how estrogen loss impacts muscles, bones, and connective tissues.

Wright’s argumentative contribution is central to the book’s prevention-forward message. She advocates for progressive resistance training and earlier recognition of MSM as foundational strategies to preserve mobility and long-term independence. Her work informs Haver’s prescriptions for building strength and resilience, positioning muscle as an essential component of comprehensive menopause care.

Dr. Mosconi is a prominent neuroscientist and director of the Women’s Brain Initiative at Weill Cornell Medicine. As the author of The XX Brain and The Menopause Brain, her research provides the scientific backbone for the book’s brain-first model of perimenopause. Mosconi’s work uses advanced neuroimaging and biomarker analysis to reframe menopause as a critical neurological transition, demonstrating how estrogen dynamics influence brain structure, energy metabolism, and long-term cognitive health. Her work is crucial for validating symptoms like brain fog, mood swings, and memory lapses as physiological phenomena, not psychological failings.

Haver cites Mosconi’s work to anchor claims about sex-specific brain aging and the neurological roots of perimenopausal symptoms. Mosconi’s methodology translates endocrine changes into measurable effects, showing how fluctuating estrogen impacts everything from mood regulation to dementia risk. This evidence is vital to the book’s argument that Hormones Drive Midlife Mood and Cognition and that neurological symptoms thus deserve serious clinical attention. For instance, Haver adopts Mosconi’s framing by defining estrogen as a “sex hormone” with whole-body, and especially whole-brain, effects, rather than simply a reproductive hormone.

Mosconi’s primary contribution to the book’s argument is her emphasis on early and targeted prevention. By separating the effects of endocrine aging from chronological aging, she makes the case that perimenopause is a window of opportunity to implement strategies that protect long-term brain health. This perspective aligns perfectly with Haver’s theme of using perimenopause as a chance to proactively manage health, justifying earlier screening and interventions to support cognitive resilience for decades to come.

Dr. Crawford is a double-board-certified reproductive endocrinologist and infertility specialist who co-founded Fora Fertility in Austin, Texas. She represents the crucial intersection of late-reproductive planning and the onset of perimenopause, a reality for many women pursuing pregnancy later in life. Her expertise informs the book’s guidance on evaluating ovarian reserve, understanding the limits of cycle-tracking during this transition, and making time-sensitive decisions about fertility treatments like IVF and embryo banking.

Crawford’s role in the text is to ground fertility guidance in frontline clinical practice. She clarifies complex diagnostic pathways, explaining tests for anti-Müllerian hormone and FSH as well as the significance of age-related decline in egg quality. Her methodology emphasizes evidence-based counseling to help patients navigate choices between treatments like IVF and intrauterine insemination and consider proactive measures such as embryo banking. This practical advice aims to minimize delays and empower women to make informed decisions during a hormonally volatile time.

Her argumentative contribution highlights the often-unrecognized overlap between the postpartum period and perimenopause for women who have children later in life. Crawford advocates for more hormone-aware follow-up care after childbirth in this demographic, aligning with the book’s broader theme of integrated, life-stage-aware women’s healthcare. By connecting reproductive goals with symptom management, her insights help create a more holistic approach to health for women in their late thirties and forties.

Dr. Rubin is a board-certified urologist with fellowship training in sexual medicine. She is a leading voice in a new wave of clinicians working to normalize women’s sexual health as a core component of medical care. Rubin is known for her direct, evidence-based public education that dismantles myths and empowers patients. Her anatomy- and hormone-literate approach underpins the book’s discussions of GSM, low libido, and the role of testosterone.

Haver highlights Rubin as a catalytic public educator whose work has galvanized mainstream interest in sexual health during menopause. She specifically points to Rubin’s influential appearance on The Drive podcast, which she describes as an electrifying master class that “brought the data, the heat, and the full, unapologetic truth” about female anatomy and sexual medicine (175-76). This interaction demonstrates Rubin’s significant influence on the book’s urgent and unapologetic tone regarding women’s right to sexual well-being.

Dr. Streicher is a clinical professor, a North American Menopause Society-certified menopause practitioner, and the founding medical director of the Northwestern Medicine Center for Sexual Medicine and Menopause. Her work has been instrumental in mainstreaming integrated, multidisciplinary care models for midlife women within academic medicine. She is significant to the book for providing practical, clinic-ready strategies for addressing GSM, painful intercourse (dyspareunia), and other sexual-health concerns.

By leading one of the first major hospital-based centers that unites menopause and sexual medicine, Streicher models the comprehensive care pathways that Haver advocates for. Her peer-reviewed guidance and public education efforts substantiate the book’s clinical recommendations, translating research into actionable advice for both patients and other clinicians. Haver cites her as a key figure who provides “clinical strategies [she] could implement immediately” (175), emphasizing her role in bridging the gap between academic knowledge and everyday practice.

Dr. Nagoski is a sex educator and researcher with a PhD in health behavior, best known for her best-selling book Come As You Are. She is significant for bringing rigorous, stigma-busting sex science into mainstream culture, shaping how clinicians and the public understand female desire. Her evidence-based frameworks for sexual well-being directly inform the book’s discussions of libido, arousal, and the importance of context in midlife sexual health.

Haver highlights Nagoski for her work in reframing desire “through the lens of neuroscience, psychology, and real-life complexity” (175). Nagoski’s core concept of responsive desire—desire that arises in response to pleasure, rather than spontaneously—is particularly important. It allows for a reframing of midlife libido changes as a normal variation rather than a deficit or dysfunction, helping to remove shame and pathologization. Her ability to bridge laboratory science with the realities of everyday relationships has made her models widely adopted by educators and clinicians, including Haver.

Dr. Bluming, an oncologist, and Dr. Tavris, a social psychologist, are the co-authors of the influential book Estrogen Matters. Together, they represent a prominent contrarian voice that challenged the fear-based narratives surrounding MHT that emerged after the Women’s Health Initiative study in the early 2000s. Their work combines clinical data with communication science to argue for a more risk-balanced and benefits-inclusive view of estrogen therapy for appropriate patients.

Bluming and Tavris’s critique of the Initiative’s framing and their clear articulation of MHT’s benefits helped catalyze a renewed debate among clinicians and the public. Haver cites their book as a “fearless” work that helped “dismantle the fear-based narrative around hormone therapy” (13). Their legacy lies in influencing both patient and clinician decision-making, validating the book’s own call to reconsider MHT and fostering a more nuanced, individualized approach to menopause care.

Dr. Casperson is a board-certified urologist, author of You Are Not Broken, and host of a popular podcast of the same name. She is a key figure in a clinician-led movement dedicated to normalizing conversations about women’s sexual health and providing evidence-based care for libido and pleasure. Casperson is cited in the book as an influential, plain-spoken voice who effectively dismantles shame and broadens the clinical conversation about desire.

Haver highlights Casperson for her role in shifting cultural norms toward validating women’s sexual-health concerns. Her work centers on anatomy-based sexual education and empowers women to understand their bodies and advocate for their own pleasure. Haver notes that Casperson “dared to say out loud what so many of us had been taught to tiptoe around: that women deserve pleasure, that sexual dysfunction is treatable, and that shame has no place in the exam room” (175). This acknowledgment positions Casperson as a crucial ally in the book’s mission to promote a sex-positive, science-based stance on midlife well-being.
