You Were in Your Grandmother's Womb
And Other Things About Your Eggs That Will Change How You See Your Fertility
We Hear a Lot About Egg Quantity. What About Egg Quality?
If you're on the fertility journey, you have probably heard a great deal about your eggs. About how many you have left. About how the quality declines. About the clock, and the numbers, and what the statistics say about women your age. What you probably haven't heard — what most women never hear — is the other part of the story. The part that is far more extraordinary, far more nuanced, and far more hopeful than the narrative of depletion and decline. Let's talk about what your eggs actually are. Because when you understand their biology — really understand it — something shifts.
Your Egg Is the Largest Cell in the Human Body
Of the trillions of cells in your body, the egg cell (oocyte) is unique.
At approximately 100 micrometers in diameter, it is the largest cell in the human body and one of the few cells visible to the naked eye. By volume, it is hundreds of thousands of times larger than a red blood cell.
This size is no accident.
The egg must provide everything needed to support the earliest stages of life before a developing embryo can draw resources from any other source. It is packed with:
Mitochondria (the cell's energy producers)
Nutrients
Cellular machinery
Protective structures
In many ways, the egg is the most generously equipped cell in the human body.
The Special Mitochondria Inside Your Eggs
Every cell contains mitochondria, which generate energy for the body.
But the mitochondria found inside egg cells are different.
Most cells create energy through pathways that produce reactive oxygen species—sometimes called cellular "exhaust." Over time, these compounds contribute to aging and cellular damage.
Egg mitochondria appear to minimize this process, creating less oxidative stress and offering built-in protection against some of the mechanisms associated with aging.
Even more fascinating, research has found that the mitochondrial DNA inside egg cells appears far more stable than many other tissues in the body. While other cells accumulate genetic changes over time, egg cells show an impressive ability to preserve their integrity.
Your Eggs Respond to Your Environment
One of the most empowering findings in fertility research is that eggs are not isolated from the rest of your life.
They live within your body's environment and respond to it.
Emerging research suggests that factors such as:
Nutrition
Sleep quality
Stress levels
Emotional wellbeing
Nervous system regulation
all contribute to the environment in which eggs develop and mature.
This is not about blame or perfection.
It is about recognizing that your body is responsive rather than fixed. The science increasingly suggests that supporting your overall health may also support the environment surrounding your eggs.
Instead of seeing fertility as entirely outside your influence, you can begin to focus on the areas where you do have agency:
Nourishing your body
Prioritizing rest
Regulating stress
Cultivating emotional wellbeing
Creating a sense of safety within your nervous system
These are not simply wellness practices—they are ways of supporting the biological environment your eggs experience every day.
New Research Is Challenging Old Assumptions
For decades, women were taught that they are born with a fixed number of eggs and that this number only decreases throughout life.
While this remains the dominant understanding, new research is exploring more complex possibilities. Scientists have identified cells called oogonial stem cells, which may have the potential to generate new oocytes under certain conditions. This remains an area of active debate and ongoing research, but it has opened important new conversations in reproductive science.
Researchers are also investigating how the ovarian environment influences egg health.
A 2024 study published in Nature Aging found that aged oocytes exposed to a younger follicular environment demonstrated improved mitochondrial function, better chromosomal integrity, and significantly higher live birth rates.
The science is still evolving.
What is important to remember is that fertility research continues to develop, and our understanding of egg quality is far from complete.
You Were Once in Your Grandmother's Womb
Now for one of the most extraordinary facts in reproductive biology.
Female eggs begin forming before birth.
When your mother was pregnant with you, the earliest forms of the eggs you carry today were already developing inside your tiny fetal ovaries.
This means that when your grandmother carried your mother, the earliest biological beginnings of you were already present.
Three generations existed together in one womb:
Your grandmother
Your mother
You
All at the same time.
There is something profoundly moving about this reality.
You were part of your grandmother's story long before you had a name.
Your eggs have traveled with you through every experience of your life. They have endured everything you have endured. They are part of a biological lineage that stretches back through generations of women who survived, adapted, loved, and persevered..
A Mind-Body Perspective on the Maternal Line
In my work with women on the fertility journey, one theme appears again and again: the importance of healing and understanding the maternal line.
This does not mean blaming your mother or attempting to resolve every challenge in your family history.
Rather, it is an invitation to bring awareness, compassion, and peace to the relationships and stories you may be carrying forward.
Through guided visualization, hypnosis, and mind-body practices, many women report feeling:
Lighter
More connected
Less burdened by inherited patterns
More open to receiving motherhood
The goal is not perfection.
The goal is creating a sense of continuity, belonging, and emotional safety as you move toward becoming a mother yourself.
What This Means for Your Fertility Journey
The fertility conversation is often dominated by fear.
Fear of age.
Fear of numbers.
Fear of running out of time.
The biology tells a more nuanced story.
Your eggs are remarkable cells designed with extraordinary protective mechanisms. They respond to the environment you create through your daily life. Researchers continue to discover new possibilities regarding egg health and ovarian function. And woven through it all is the resilience of the women who came before you.
You are more than a lab value.
You are more than a statistic.
You are a woman with a responsive, resilient biology and a story that cannot be reduced to a single number.
