For a long time, menopause was treated as a problem to be solved — a hormonal failure, an inevitable decline. But the most recent science is rewriting that narrative. Studies published in journals like Nature and The Lancet show menopause isn't a disease. It's a complex biological transition — and, more importantly, a window for understanding and protecting your long-term health. Levvi helps women at every stage track the health markers that matter most during this transition.
What determines when menopause arrives? What happens in your ovaries decades before the first symptoms? And what can you do, at any age, to influence this process? Here's what the latest research reveals.
What Is Ovarian Aging
Ovarian reserve is the total number of immature follicles present in the ovaries. A woman is born with approximately 1 to 2 million follicles. By puberty, that number has already fallen to around 300,000 to 400,000. From that point, with each menstrual cycle, follicles are recruited and the majority undergo atresia — a natural elimination process.
This process is continuous and gradual. Menopause — clinically defined as 12 consecutive months without a period — is simply the final marker of an ovarian aging process that began decades earlier. According to a review published in GeroScience, genetics is the primary determinant of menopause timing, but physical activity, diet, and lifestyle also exert significant influence.[1] Levvi tracks sleep quality, energy, and cycle regularity — all of which reflect this underlying ovarian health trajectory.
The progressive decline in ovarian reserve doesn't only affect fertility. Low estrogen levels after menopause — natural or premature — are associated with increased risk of cardiovascular disease, osteoporosis, and cognitive decline.[1] This makes ovarian aging a matter of whole-body health, not just reproductive health.
The Genetics of Menopause
A large-scale study published in Nature analyzed genetic data from approximately 200,000 women of European ancestry and identified 290 genetic variants associated with the age of natural menopause.[3] That's a striking number — and it reveals that menopause isn't governed by a single biological switch, but by a complex network of processes.
Among the most relevant mechanisms identified are DNA damage response (DDR) processes. Ovaries are especially vulnerable to accumulated genetic damage over a lifetime, and the body's ability to repair that damage directly influences the rate at which ovarian reserve is depleted.[3] The more efficiently your cells repair DNA, the slower your ovarian aging tends to progress.
One particularly striking finding: women in the top 1% of genetic susceptibility show a risk of premature ovarian insufficiency equivalent to carriers of FMR1 premutations.[3] This means genetics can explain why some women enter menopause decades earlier than others — and opens the door to predictive testing in the future. For now, tracking your cycle over years in Levvi provides the kind of longitudinal data that helps detect irregularities early.
Mitochondria and Ovarian Longevity
If genetics defines the potential, mitochondria define the execution. Levvi's energy tracking feature reflects one of biology's most fundamental processes: a review published in Frontiers in Endocrinology describes mitochondria as epigenetic regulators of ovarian aging.[4] In plain terms, these organelles don't just supply energy to eggs — they also control chemical processes that determine how ovarian genes are activated or silenced.
Mitochondrial dysfunction is considered a hallmark of ovarian aging. When mitochondria underperform, they produce fewer essential co-substrates — such as acetyl-CoA, NAD+, and ATP — that regulate gene expression in the ovaries. This creates a feedback loop: dysfunctional mitochondria accelerate ovarian aging, which in turn worsens mitochondrial function.[4]
The good news is that mitochondrial function is modifiable. Regular physical exercise, an antioxidant-rich diet, and high-quality sleep are the 3 lifestyle factors with the strongest evidence for supporting mitochondrial health — and by extension, ovarian longevity. Levvi tracks all three, giving you a daily picture of how well you're supporting these systems.
Menopause as a Health Opportunity
The menopause series published in The Lancet in 2024 proposes a fundamental shift in perspective. Rather than treating menopause as an endocrine deficiency, the authors present an empowerment-based model built on the WHO definition: an active process of gaining knowledge, confidence, and self-determination to manage your own health.[2]
The model recognizes that the menopause experience varies enormously between women. Psychological, social, and contextual factors — many of them modifiable — influence the transition as much as biology does. Hormone replacement therapy (HRT) can be an important tool for many women, but it isn't the only answer. The Lancet model proposes that menopause care should include education, psychological support, and lifestyle interventions alongside HRT when needed.
Nearly 1 billion women worldwide are postmenopausal. Menopause isn't a rare or marginal event — it's a universal experience that deserves rigorous scientific attention and individualized care. Apps like Levvi that track health data longitudinally can play a meaningful role in that care.
What You Can Do Now — At Any Age
Science shows that ovarian aging isn't fully determined by genetics. Lifestyle factors influence the pace of this process and the quality of the menopausal transition. Here are the key levers:
Exercise: regular physical activity improves mitochondrial function, reduces oxidative stress, and is associated with a later age of menopause.[1] It doesn't need to be intense — regular walks, yoga, and light strength training already make a difference. Levvi's energy and cycle tracking helps you time workouts for phases when your body is most receptive.
Diet: foods rich in antioxidants (fruits, vegetables, oily fish) help protect mitochondria and reduce DNA damage in ovarian follicles. Inflammatory diets and excessive ultra-processed food consumption have the opposite effect.[1] An anti-inflammatory diet also supports the cardiovascular and bone health that becomes increasingly important after menopause.
Sleep quality: sleep is when the body performs cellular repair processes, including mitochondrial maintenance. Chronic sleep disturbances are associated with accelerated cellular aging and increased oxidative stress.[4] Levvi tracks your sleep patterns over time, making it easier to identify when disrupted sleep aligns with hormonal changes in your cycle.
Stress management: chronic stress increases inflammatory markers and oxidative damage, both of which accelerate ovarian aging. Evidence-based practices — meditation, breathwork, social connection — are effective strategies for mitigating these effects.[2] Levvi's mood and energy logs help you identify stress patterns before they become chronic.
Frequently Asked Questions
Is hormone replacement therapy necessary for all women in menopause?
No. Hormone replacement therapy (HRT) can be highly beneficial for women with intense symptoms — especially hot flashes, vaginal dryness, and elevated osteoporosis risk. However, the decision should be individualized, considering health history, age, and personal preferences. The Lancet empowerment model emphasizes that HRT is one tool among several — not the default solution for every woman going through menopause.
Can supplements slow ovarian aging?
Research on supplements like CoQ10, NAD+, and resveratrol is promising in animal models but still preliminary in humans. Current science suggests the best strategy is maintaining habits that support mitochondrial function — exercise, good nutrition, and quality sleep — rather than relying on isolated supplements.[4] Levvi makes it easier to sustain these daily habits with reminders and tracking. Talk to your doctor before starting any supplementation.
At what age should I start caring about ovarian health?
Ovarian aging is a continuous process that starts long before any symptoms appear. The habits you build in your 20s and 30s influence the health of your ovaries in the decades that follow. It's not about worry — it's about awareness. Knowing your cycle, maintaining healthy habits, and talking to your gynecologist about markers like AMH (anti-Müllerian hormone) are steps you can take at any age. Levvi's long-term cycle tracking builds the baseline data that makes these conversations with your doctor much more meaningful.
