To understand menopause with the same depth of knowledge as an obstetrician, one's journey of discovery should commence from the initial trimester of fetal growth. During this stage, the maturation of each egg a woman has is concurrent with the progression of her ovaries and other reproductive structures. Immature eggs are encompassed by the tissue that forms primordial follicles. By the time a fetus reaches the midpoint of gestation, it will have formed the peak number of undeveloped egg cells, approximately six to seven million in total. Gunter highlights the inaccuracy in describing the time of maximum follicle count as a "peak," suggesting that it inappropriately magnifies the significance of a normal physiological occurrence like menopause.
The quantity of immature oocytes starts to decrease due to atresia when the gestation period reaches the twentieth week. Upon reaching puberty, an individual typically has around 300,000 immature egg-containing structures within their ovaries. Gunter likens it to sowing too many seeds in a single container, which subsequently allows for the culling of the less robust ones, thereby giving the most vigorous ones the optimal opportunity to flourish. Hormonal signals trigger the commencement of follicle maturation during puberty, ultimately leading to the release of a mature egg each month.
During the period leading up to a woman's last menstrual cycle, when estrogen levels decline, there is often a hormonal tumult, and it is during this phase that numerous women experience their most severe symptoms, as noted by Gunter. Jen Gunter characterizes the beginning of menopause as a time marked by a swift reduction in the number of follicles, alterations in hormonal production from those that remain, and changes in the hormonal communication within the brain. A variety of factors influence the transition. As women grow older, the quantity of ovarian follicles decreases and there are changes in brain function that influence hormonal regulation, accompanied by a reduction in blood flow to the ovaries.
A range of hormones, including [restricted term] which plays a leading role in the production of estrogen before menopause, as well as [restricted term], progesterone, follicle-stimulating hormone, [restricted term], and [restricted term], are involved in the process. The ovaries often halt estrogen production, a process which medical texts frequently describe as a state of 'exhaustion.' Gunter challenges the prevalent terminology, arguing that it implies ovarian dysfunction, whereas it actually represents their normal functioning.
Gunter emphatically rejects the erroneous notion that menopause is a consequence of modern hygiene and medical care, which allegedly allows women to outlive their "biological usefulness." Historical evidence from ancient civilizations suggests that individuals who survived the perils of infancy frequently lived into their sixties and seventies. She supports her assertion with contemporary evidence from societies of hunter-gatherers, indicating that a woman who reaches the age of 45 is likely to live until she is between 65 and 67 years old. Gunter suggests that the extended lifespan of humans compared to other mammals such as chimpanzees is largely attributed to the role of grandmothers, as opposed to improvements in hygiene or contemporary medical treatments.
The concept that menopause offers an evolutionary benefit, termed the grandmother hypothesis, posits that women who are no longer in their reproductive years can enhance the chances of survival and overall health of their grandchildren. Human childbirth is physically demanding because of our large skulls and narrow pelvises. Once born, infants are dependent on their mothers for food, shelter, and care for many years, limiting a woman's ability to provide for herself and other offspring. After menopause, numerous women experience a newfound freedom from past obligations, which enables them to devote increased attention to raising their grandchildren.
Gunter strengthens the concept that grandmothers play a crucial role in evolution by referencing studies that have tracked human births and fatalities. Research shows that the closer grandmothers live to their offspring, the higher the likelihood of a larger number of grandchildren, demonstrating that for every ten years a grandmother continues to live, there is an average rise of two additional grandchildren. Research on the traditional hunter-gatherer activities of Hadza women in Tanzania reveals that grandmothers are vital, spending significant time foraging and caring for grandchildren, especially when their daughters are breastfeeding.
Some species thrive despite having lost their reproductive capabilities. Orcas, the aquatic creatures often referred to as orcas, typically stop giving birth in their forties but can live for more than fifty years. Researchers have observed that in the Pacific Northwest, elder female orcas pass on their knowledge of foraging, which supports the survival of their offspring's progeny and...

Our society, which is patriarchal in nature, often maintains a pervasive silence regarding menopause. Many women find themselves unprepared for the sudden changes their bodies experience, frequently due to a lack of dialogue about menopause with their healthcare providers or within their social circles. Unlike puberty, there is no curriculum in schools preparing girls for menopause, and medical professionals rarely discuss it with their patients until after symptoms are present.
Gunter contends that the lack of adequate education and discussion on this subject is harmful as it results in women lacking a complete comprehension of their physiology, thereby perpetuating the belief that the shift toward menopause is inherently challenging, regardless of the severity of the symptoms. Healthcare providers often minimize the issues raised by women or their requests for medical attention, particularly in the...
The concept of employing hormone therapy to mitigate menopausal symptoms emerged in the late 1800s, despite the fact that estrogen and other hormones were unidentified at that time. Gunter explains that, early on, clinicians experimented with injecting extracts from various organs (such as pig ovaries, amniotic fluid) believed to contain these unknown hormonal signals into animals as a proxy for human biology, even though they did not fully understand what was happening. The initial human trials introduced the first methods aimed at tackling symptoms linked to the menopausal transition. Many approaches were found to be ineffective and, in certain instances, led to considerable negative consequences.

Gunter underscores the importance of maintaining a nutritious diet during the transition into menopause, although she acknowledges the complexity of nutritional science. Adopting a nutritional regimen that emphasizes the consumption of foods with high nutritional value necessitates a thorough evaluation of commonly consumed items that may be overly processed and deficient in vital nutrients. Gunter recommends a diet that focuses on reducing consumption of overly processed foods and items rich in simple sugars, which have been linked to an increased likelihood of developing heart disease and type 2 diabetes.
It's crucial to assess the equilibrium of saturated and unsaturated fats after reducing consumption of highly processed foods and sugars that are quickly broken down and absorbed by the body....
