Why Women After 35 Sometimes Release More Eggs: The Biological Clearance Sale

By Dr. Nutan Pakhare

“Doctor, I heard women after 35 can have twins more easily. Isn’t fertility supposed to go down after that age?”

This question often comes up in clinics, consultations, and even casual conversations. The answer usually surprises people.

Yes, the chance of having natural fraternal twins does increase slightly between the ages of 35 and 45. But no, this does not mean fertility improves during this time.

To understand this fascinating biological paradox, it helps to step away from medical terminology and look at something very familiar.

The Store Analogy: How Young Ovaries Work

Imagine a well-established store in its early years. The shelves are full, the products are of premium quality, and the owner releases one carefully selected item at a time with confidence.

This is very similar to how the ovary functions in a woman’s 20s and early 30s. During this stage of life, the ovaries contain a large reserve of eggs and hormonal control is highly precise. Each menstrual cycle typically results in the release of a single mature egg. The system works calmly and efficiently, selecting the best candidate each month.

When Time Passes and the Store Changes

As years go by, the store owner begins to notice subtle changes. The stock is slowly reducing, some products do not sell as easily, and the future of the store becomes less predictable.

At this stage, a wise store owner might respond with a clearance sale. Instead of releasing one item at a time, several items may be placed on the shelves together. The aim is simple: increase the chances that something sells.

This does not mean the store has suddenly become richer. It simply means the store is responding intelligently to time.

What Happens in the Female Body After 35

A similar shift happens within the female reproductive system after the mid-thirties. As a woman enters her late 30s and early 40s, the number of eggs in the ovaries gradually declines and egg quality becomes more variable. The ovaries also become less responsive to hormonal signals.

Long before a woman consciously notices these changes, the brain senses them. In response, it increases the production of a hormone called Follicle Stimulating Hormone (FSH). This hormone essentially signals the ovaries to try harder and respond more actively.

Because of this stronger signal, more than one follicle may mature during a menstrual cycle. As a result, instead of releasing a single egg, the ovary may release two or sometimes more eggs. This phenomenon is known as hyperovulation.

If two of these eggs are fertilised during the same cycle, the outcome is fraternal (non-identical) twins.

Why More Eggs Do Not Mean Better Fertility

This is where a common misunderstanding arises. Many people assume that if more eggs are being released, fertility must be improving. In reality, the opposite is often true.

Returning to the clearance sale analogy helps clarify this. During a clearance sale, more products may be available at once, but their quality and demand may vary. The store is not expanding—it is adapting to changing circumstances.

Similarly, as reproductive age advances, overall fertility gradually declines. The risk of miscarriage increases, and chromosomal abnormalities become more common. The body releases multiple eggs not because reproductive strength is increasing, but because it is compensating for decreasing certainty.

This is not a failure of the system. It is an example of biological intelligence.

Why Identical Twins Are Different

Another question frequently arises: does age also increase the chance of identical twins?

The answer is generally no. Identical twins occur when a single fertilised egg splits into two embryos. This process appears to happen randomly and is not significantly influenced by maternal age.

The age-related increase in twin pregnancies is mainly associated with fraternal twins, which occur when multiple eggs are released and fertilised in the same cycle.

What Science Shows

Large population studies from multiple countries have consistently shown that women between the ages of 35 and 45 have a slightly higher rate of natural fraternal twins compared to younger women.

Researchers attribute this to higher baseline levels of FSH, reduced ovarian sensitivity to hormones, and the recruitment of multiple follicles during ovulation. Modern reproductive science now explains these mechanisms clearly.

Yet interestingly, traditional systems of health had long observed similar patterns, even without the language of hormones.

What Ancient Wisdom Observed

Long before hormone levels could be measured, traditional health systems noticed that the reproductive system changes gradually over time. As reproductive life progresses, the body tends to shift from precision toward compensation. Effort increases as resources slowly decline.

In this sense, the body prioritises continuity rather than perfection.

The female body does not suddenly “decline” after 35. Instead, it begins to adapt its strategy.

The Ayurvedic Perspective

From an Ayurvedic perspective, this phase reflects Raja-kṣhaya, a gradual reduction in reproductive strength influenced by increasing Vāta. As Vāta becomes more dominant with age, the reproductive system may become less stable and more variable in its responses.

Rather than indicating excess, the release of multiple eggs represents the body’s attempt to compensate. Ayurveda therefore emphasises nurturing ojas, calming Vāta, and supporting reproductive tissues (dhātus) through mindful living, balanced nutrition, emotional stability, and restorative practices.

The principle is simple: fertility after 35 is less about force and more about alignment.

What This Means for Women Today

For women trying to conceive after 35, or those curious about how fertility changes with age, the key message is reassuring. The body is not working against you—it is working with time.

However, this also means that conscious support becomes more important. Thoughtful lifestyle choices, balanced nutrition, stress management, and holistic reproductive care can make a meaningful difference during this stage of life.

When the body is working harder, it benefits from deeper care.

The Intelligence of the Clearance Sale

A clearance sale is not a sign of panic. It is a thoughtful response to changing circumstances.

In the same way, the release of multiple eggs after 35 is not a miracle, a guarantee, or a sign of stronger fertility. It is the body adjusting its strategy, increasing effort where certainty has become lower.

And that adaptation is remarkable.

After 35, the female body does not give up. It simply negotiates harder, much like a well-timed clearance sale.
