Why Menopause Happens: Biological Causes, Evolutionary Insights & Natural Support

🧠 Understanding Why Menopause Happens

Why Menopause Happens: Menopause is a natural biological transition, typically occurring between ages 45 and 55. It marks the end of menstruation and reproductive capacity, defined as 12 consecutive months without a period.


🔬 The Biological Cause: Ovarian Follicle Depletion

At birth, reproductive individuals have around 6–7 million ovarian follicles — tiny sacs in the ovaries containing immature eggs. By puberty, this number falls to 300,000–400,000, and only about 500 will ever fully mature and be released during ovulation.

As we age, the remaining follicles decline in both quantity and quality. The ovaries gradually become less responsive to follicle-stimulating hormone (FSH) and luteinising hormone (LH), leading to irregular ovulation and eventually a complete stop.

This process causes a sharp drop in estrogen and progesterone production, which in turn disrupts the balance of other hormones such as FSH, LH, and testosterone.


🧠 Why Hormone Changes Trigger Symptoms

Estrogen and progesterone are involved in far more than reproduction — they influence:

  • 🌡 Body temperature regulation via the hypothalamus (explains hot flushes)

  • 🧠 Neurotransmitter balance in the brain (affecting mood and sleep)

  • ❤️ Cardiovascular health (impacting cholesterol and blood vessel function)

  • 🦴 Bone density maintenance through calcium regulation

  • 💧 Skin and tissue hydration via collagen production

When these hormones decline, multiple systems feel the effects — which is why menopause can cause wide-ranging symptoms rather than just period changes.


🧬 Evolutionary Theories

Why do humans experience menopause when many animals don’t?

  • 👵 Grandmother Hypothesis – Redirecting energy from reproduction to caring for grandchildren helped survival.

  • 🤱 Mother Hypothesis – Ceasing late-life reproduction reduced pregnancy risks and allowed focus on existing children.


❤️ Why Menopause Matters for Health

Menopause brings changes beyond the end of periods:

  • 🌡 Vasomotor symptoms – Hot flushes, night sweats

  • ❤️ Cardiometabolic changes – Higher risk of heart disease, weight changes

  • 🦴 Bone health concerns – Increased osteoporosis risk due to bone density loss
