for more than twenty years, i have bled monthly. that is more than half of a typical fertile lifespan spent in a rhythm i barely questioned. but when do the cycles begin to change? what happens to the body, mind, mood, and identity when hormonal shifts occur? and why did no one teach me to expect this?
i remember my mother complaining about hot flashes when i was very little. i suppose that her transition to menopause was synchronized with my transition into rebellious teenage years. we never discussed my periods, and i never got to ask my mother or grandmothers about their symptoms or when their last periods came. they were already gone when i began to wonder.
so i want to speak about it now: about eggs and their disappearance, about the legitimacy of hrt and the legitimacy of refusing it, about the grief and freedom of becoming post-reproductive.
before a girl is born, her ovaries already contain millions of immature eggs, or oocytes. the number peaks in fetal life, then declines relentlessly through childhood, puberty, and adulthood.
the timing of the first period is dictated by genetics, stress, and body composition. girls with higher body fat tend to menstruate earlier, while undernutrition and low body fat can delay puberty. there is also a hypothesis that the presence of an unrelated adult male in the household (often a stepfather) may be associated with earlier menarche.
puberty signifies the beginning of the fertile years, and the body learns to run on cyclical hormones. oocytes go through a massive selection process every month, which allows the ovary to recruit many follicles and choose the one most likely to mature and ovulate.
in adulthood ovulation and stable predictable periods become an important vital sign. by the age of thirty, women are, on average, down to about 10% of their initial egg supply. aging oocytes also become less efficient at repairing dna damage; research links this declining repair capacity to reduced fertility and ovarian aging. this is why dna repair enhancement is an exciting research direction.
perimenopause is a whole-body transition shaped by genetics, reproductive history, stress, health conditions, nutrition, movement, environment, and social context. it often begins in the mid-40s, though it can begin in the mid-30s for some individuals, and it can last for up to 10 years. periods become closer together, farther apart, heavier, lighter, or suddenly absent. hot flashes, night sweats, insomnia, anxiety, low mood, brain fog, joint pain, and changes in body composition (the actual list of possible symptoms is way longer) can all arrive as a system recalibrates. this is where the identity shift begins as well. a woman may be grieving fertility while also feeling relieved by it. she may feel more powerful and less tolerant of nonsense, while simultaneously feeling unfamiliar in her own body.
menopause is inevitable, though i have heard about technology being developed for women who freeze eggs early to implant them later, delaying or avoiding menopause. currently, the most reliable solution for a smoother experience is natural or synthetic hormone support via herbs or pills. certified herbalists can prescribe a combination of herbs suited to your body’s needs, and functional medicine doctors use bioidentical medication; they say that the benefits of hormone replacement therapy are likely to outweigh the risks.
i understand the hesitation around hrt. introducing external hormones into a body that is already inflamed, insulin-resistant, possibly sleep-deprived, or carrying excess visceral fat can feel like adding overwhelm to a system that needs inner stillness and regulation. there should be more awareness of the root causes of modern physical and emotional symptoms during aging and hormonal transitions — in most cases, they stem from disconnection from natural rhythms, movement, and clean food; vitality and body composition changes are tied to the gut microbiome and systemic inflammation caused by lifestyle and environmental toxins.
but “natural” is a slippery word. menopause itself is natural; so are bone density loss, debilitating hot flashes, and years of broken sleep — all while you’re required to perform in the modern world and show up as your best self for your family or career. the question is not whether hrt is natural, but whether it is appropriate, well-timed, individualized, and paired with attention to the whole person. menopause care is not about replacing what is lost, but rather about supporting the systems and the microbial world within us.
gut bacteria may influence how much estrogen the body retains or eliminates. higher beta-glucuronidase activity can increase estrogen recirculation, but this is not automatically good or bad. it depends on the wider hormonal and metabolic context.
menopause is diagnosed after 12 months without a period. what follows — postmenopause — can occupy decades. if we are likely to live long lives, then this is not an epilogue. it is a second half that asks for foresight.
i can’t ask my mother or my grandmothers when they had their last periods. they were all fully decomposed in the soil by the time i became interested in what i have to expect from my body. i have never liked being the daughter of old parents. my mother was 40 when i was born, and i don’t want to be an old mother myself. i have collected a few baby names and signature mommy scent ideas over the last few years, but i don’t want to have children with a non-ideal partner or no partner at all just because of the timing pressure as i’m approaching a threshold.
menopause is not the end of womanhood. it is the moment when womanhood becomes less defined by cycles and more defined by choice. we can meet this hormonal shift with knowledge and with a vision of postmenopause as a long, capable, and potentially marvelous part of it.
the practical takeaway is to have a conversation with your mother about her hormonal journey, if possible, and to start supporting the whole system asap: adequate protein and fiber, strength training, regular movement, sleep, stress regulation, and reducing avoidable exposures where possible. these habits can meaningfully affect energy, body composition, mood, and long-term health.
