Part 3: “Sex, Pregnancy, and Periods in Perimenopause”

Part 3, Chapter 11 Summary: “When Desire Shifts: Perimenopause and Sexual Function”

V.C., now 53, had heavy periods beginning in her mid-forties, followed by distressing declines in sexual function in her late forties. After delaying intervention while researching ablation and hysterectomy, she started MHT for other symptoms, which normalized her bleeding.


Haver reflects that she was ill-equipped to address midlife changes in desire and pleasure early in her practice, noting that medical training offered little on female sexual function during perimenopause. She regrets earlier, dismissive advice that overlooked underlying hormonal shifts and left patients without meaningful help. To close these gaps, she sought out experts—among them Dr. Kelly Casperson, Dr. Emily Nagoski, Dr. Lauren F. Streicher, and urologist Dr. Rachel S. Rubin—whose work sharpened her understanding of testosterone, clitoral anatomy, and sexual dysfunction.


The chapter explains how estrogen supports vaginal tissue, blood flow, and lubrication; when levels fall, tissues thin and sex can become painful, a pattern encompassed by genitourinary syndrome of menopause (GSM). Testosterone, which declines from the mid-twenties, influences libido and satisfaction. Although data support its use for hypoactive sexual desire disorder, no Food and Drug Administration (FDA)-approved testosterone product exists for women in the United States. The Endocrine Society and the International Society for the Study of Women’s Sexual Health endorse testosterone for postmenopausal women with low desire, and clinicians may consider it for perimenopausal patients when appropriate.


Physical discomfort can erode emotional intimacy and create negative feedback loops. Haver differentiates spontaneous desire from responsive desire, noting that the latter is often more common in midlife. Concurrent caregiving and career demands, chronic stress, and elevated cortisol further suppress desire.


The 2025 American Urological Association guidelines for GSM recommend screening, shared decision-making, and evidence-based options including local estrogen, dehydroepiandrosterone (DHEA), and nonhormonal treatments. Haver introduces the Female Sexual Function Index and a six-question screening version for self-assessment.


Treatment options span MHT (local and systemic estrogen, DHEA, testosterone), nonhormonal therapies (moisturizers, lubricants, pelvic floor physical therapy, neuromodulators), and lifestyle measures (resistance training, quality sleep, anti-inflammatory nutrition). Haver notes clinical observations that GLP-1 receptor agonists may indirectly support libido by reducing visceral fat and inflammation. She calls for improved medical education, routine screening, and research funding to better address women’s sexual health in midlife.

Part 3, Chapter 12 Summary: “Fertility Changes and Challenges: The Clock Is Real, but So Is Your Power”

Julie S. had a baby at 43 and then attributed brain fog and mood changes to postpartum fluctuations for four years before learning—via Haver’s educational content—that she was in perimenopause. She had assumed that late menarche (first period) and a late-age pregnancy meant she was far from menopause; her clinicians did not raise perimenopause as a possibility.


Haver examines how fertility intersects with perimenopause, drawing on insights from fertility specialist Dr. Natalie Crawford. Female fertility declines gradually, more sharply after 35: The chance of conception falls from about 20% to 25% per cycle in the twenties to less than 5% by 40. This results from both a shrinking egg supply and declining egg quality. A chart illustrates that women are born with 1 to 2 million eggs, a number that falls to near zero by menopause. Shorter cycles often signal diminishing ovarian reserve, while seemingly normal cycles can mask hormonal instability that contributes to fatigue, insomnia, brain fog, and weight gain. Egg quality tends to decline faster than quantity, raising chromosomal abnormalities and miscarriage risk; more than half of pregnancies in the early forties end in miscarriage.


Erratic hormonal signaling in perimenopause undermines traditional fertility tracking, and hormonal withdrawal bleeding can be mistaken for a true period. Dr. Crawford recommends comprehensive evaluation for women in their late thirties and early forties, including ovarian reserve testing, antral follicle count by ultrasound, an anatomic assessment, and a semen analysis. For those hoping for multiple children, embryo banking via in-vitro fertilization (IVF) is a key consideration; while intrauterine insemination may cost less upfront, IVF often yields faster, more cost-effective outcomes in older patients, though success rates decline after 38.


Postpartum recovery can overlap with perimenopause, and symptoms of ovarian failure may be misattributed to normal postpartum changes. Low-dose MHT can treat perimenopausal symptoms without necessarily blocking ovulation when carefully managed. Acknowledging the emotional toll of midlife infertility, Haver encourages psychological and peer support. The chapter emphasizes informed choice and recommends Dr. Crawford’s book, The Fertility Formula.

Part 3, Chapter 13 Summary: “When the Bleeding Becomes a Mystery: Uterine Changes in Perimenopause”Part 3, Chapter 13 Summary: “When the Bleeding Becomes a Mystery: Uterine Changes in Perimenopause”

Kathryn J. experienced severe, unpredictable bleeding in 2017 that caused anemia requiring transfusion. An ultrasound revealed fibroids, and she underwent a hysterectomy. Six years later, she developed weight gain, brain fog, irritable bowel symptoms, and frequent hot flashes, wishing she had understood menopause more fully before surgery.


Haver cites The Menopause Society’s definition of perimenopause, highlighting menstrual irregularities as central. She likens perimenopause to adolescence—messy and hormonally volatile. Abnormal uterine bleeding (AUB) refers to flow outside normal limits of volume, duration, frequency, or regularity. While a true menstrual period follows ovulation and progesterone withdrawal, perimenopause often brings anovulatory bleeding that appears period-like. AUB accounts for about one-third of gynecology visits and more than 70% of consultations for perimenopausal and postmenopausal patients.


AUB can include changes in cramping and premenstrual symptoms, intermenstrual spotting, lighter or heavier flow, shortened or lengthened cycles, and missed periods. Any postmenopausal bleeding warrants prompt evaluation to rule out cancer; atrophic vaginitis, a component of GSM, is a common benign cause and is treatable with local estrogen or moisturizers.


The PALM-COEIN system classifies AUB causes as structural—polyps, adenomyosis, leiomyoma (fibroids), and malignancy/hyperplasia—and nonstructural—coagulopathy, ovulatory dysfunction, endometrial disorders, Iatrogenic causes, and unclassified. When AUB is related to perimenopause itself, options range from watchful waiting to intervention. Standard MHT often lacks sufficient dosing to control cycles; instead, clinicians use oral contraceptives, progestogens, or hormone-releasing intrauterine devices such as Mirena, which Haver favors for many patients. Nonhormonal options include nonsteroidal anti-inflammatory drugs and antifibrinolytics like tranexamic acid. Procedures include dilation and curettage, endometrial ablation, and hysterectomy.


Haver cautions that hysterectomy is not a treatment for perimenopause and carries risks, including earlier menopause—on average 4.4 years sooner—even when ovaries are retained. She encourages second opinions and thorough counseling, underscoring shared decision-making to match treatment with diagnosis, goals, and risk profile.

Part 3 Analysis

Haver continues to utilize patient testimonials to ground abstract clinical data in lived reality, such as Julie S. misattributing her perimenopausal symptoms to postpartum hormone shifts or V.C. describing her sudden decline in sexual function. By positioning these narratives before the medical exposition, the text validates the patients’ subjective experiences. This structural choice reasserts the text’s focus on Confronting Medical Gaslighting, specifically allowing patients’ confusion and distress to dictate the clinical focus of the subsequent pages. Instead of presenting abnormal uterine bleeding or hypoactive sexual desire disorder as abstract clinical phenomena, the text anchors them in the emotional and relational disruptions they cause. Broadly, this technique mirrors the book’s central project of recentering women’s midlife healthcare around the voices of patients, ensuring that lived experience drives scientific inquiry rather than being subordinated to it.


The narrative strategically deploys self-criticism to indict the systemic failures of medical education while maintaining an authoritative clinical ethos. In examining sexual function, Haver reflects on her early career and confesses that she previously offered dismissive advice to patients experiencing low libido, noting that despite her extensive background, she had received “almost no training on female sexual function” (174). This admission serves a dual rhetorical purpose. First, it humanizes the physician, dismantling the traditional hierarchy that places the doctor above the patient. Second, it shifts the blame for inadequate care from individual clinicians to a broader institutional deficit. By implicating herself in the medical gaslighting she now seeks to critique, Haver avoids directly blaming her medical peers while building trust with her lay readers. This rhetorical maneuver reinforces the text’s overarching argument that the deficiencies in women’s midlife healthcare are the result of entrenched institutional neglect and outdated curricula, necessitating systemic reform rather than just individual patient resilience.


Throughout these chapters, the text utilizes rigid structural frameworks and taxonomies to reframe seemingly ambiguous symptoms as concrete biological events. This approach is most evident in the application of the PALM-COEIN diagnostic system for abnormal uterine bleeding, which strictly categorizes causes into observable structural issues, such as polyps and fibroids, and non-structural functional issues, such as ovulatory dysfunction. Similarly, the introduction of the Female Sexual Function Index translates the nebulous experience of declining intimacy into a quantifiable metric. By providing these clinical classification tools, the narrative bypasses the cultural tendency to dismiss midlife women’s complaints as psychosomatic, stress related, or simply an inevitable part of aging. Giving patients access to specialized medical vocabulary equips them with the precise language required to advocate for themselves within clinical settings. In the broader context of the medical humanities, this democratization of diagnostic language functions as a corrective measure against an establishment that frequently gatekeeps information, empowering patients to demand evidence-based interventions rather than vague reassurances.


To mitigate the psychological distress associated with unpredictable physiological changes, the text employs conceptual metaphors that normalize hormonal volatility. Haver explicitly likens perimenopause to a “mirror image of adolescence” (210), characterizing both as stages defined by messy, erratic transitions. This metaphor extends into the discussion of fertility, where the concept of chaotic signaling illustrates the brain’s frantic response to diminishing ovarian reserves. By framing perimenopause as an adolescent-like rewiring rather than an abrupt bodily failure, the narrative strips away the shame and internalized blame often associated with unpredictable bleeding or fluctuating responsive desire. The unpredictability itself operates as an expected biological mechanism rather than a personal defect. This linguistic reframing shifts the perspective from one of pathological decline to one of natural, albeit complex, progression. Ultimately, this device supports the book’s broader philosophical stance that midlife represents a dynamic developmental stage requiring specific transitional support, directly challenging societal narratives that equate perimenopause exclusively with loss and deterioration.


Finally, the analysis of sexual health and fertility culminates in a critique of medical paternalism, underscoring a pressing mandate for patient advocacy. The text highlights glaring discrepancies in care, such as the absence of an FDA-approved testosterone product for women despite established international guidelines supporting its use for low desire. Furthermore, the narrative warns against the routine recommendation of hysterectomies for irregular bleeding without comprehensive counseling on the subsequent risks of premature menopause. These examples illustrate how the medical establishment often prioritizes generalized, extreme, or passively neglectful approaches over nuanced, individualized care that protects a woman’s quality of life. By exposing these clinical blind spots, the text insists that women must critically evaluate proposed treatments, seek second opinions, and demand shared decision-making. This advocacy-focused conclusion aligns with the work’s foundational premise that true healthcare reform requires patients who are knowledgeable enough to challenge the status quo and demand equitable, function-preserving interventions.
