Ep 386 New Research Proves It's Not Just About Your Eggs
What if the key to improving egg quality has less to do with the egg itself, and more to do with the environment it lives in? In this episode, Michelle Oravitz breaks down a landmark study out of UCSF that used cutting-edge 3D imaging to map entire human and mouse ovaries at the cellular level, and what the researchers found is reshaping everything we thought we knew about ovarian health.
The study revealed that eggs are not scattered randomly throughout the ovary. They live inside communities made up of blood vessels, nerves, and support cells, and that surrounding environment actively shapes how eggs mature and how long they last. Even more striking, the researchers discovered that sympathetic (fight-or-flight) nerves are woven throughout the ovary and play a direct role in regulating which eggs receive the signal to grow.
Michelle also explores how Traditional Chinese Medicine has been describing this exact system for thousands of years through the framework of Kidney Jing, Liver Blood, and Qi flow, and how these ancient concepts map with remarkable precision onto what modern science is now confirming.
This episode will shift the way you think about fertility. Your ovarian ecosystem is not fixed. It is alive, responsive, and shaped by how you live every day.
Key Takeaways:
Egg quality is shaped not just by the egg itself, but by the entire microenvironment surrounding it, including blood vessels, nerves, and support cells.
Fight-or-flight nerves inside the ovary directly regulate which eggs receive the signal to mature.
Ovarian blood vessel health is one of the first things to decline with age, reducing the nutrients and signals follicles need even when eggs are still present.
The ovarian environment is dynamic and responds to what you eat, how you sleep, how you move, and the state of your nervous system.
Traditional Chinese Medicine has described this system for thousands of years through Kidney Jing, Liver Blood, and Liver Qi stagnation, concepts that map directly onto what modern science is now finding.
Practical support focuses on improving circulation, nourishing Kidney Jing, regulating the nervous system, and reducing inflammation

Speaker: [00:00:00] Episode number 386 of the Wholesome Fertility Podcast. Welcome to the Wholesome Fertility Podcast. I'm your host, Michelle Orbitz. If you've ever been told your egg count is too low, your A MH isn't where it should be, or your egg quality is a concern, today's episode is going to shift something for you because a landmark study published in the journal.
Out of UCSF is changing the entire conversation about what egg quality actually means, and what I've found is something Chinese medicine has understood for a very long time. It's not just about the egg, it's about the entire ecosystem. The egg lives in today, we're breaking down that research, what it means for your fertility and the practical steps you can take to nourish your ovarian environment from the inside out through the lens of both modern science and traditional Chinese medicine.
So if you wanna learn [00:01:00] more, stay tuned.
Speaker 2: For decades, the conversation about female fertility has centered almost entirely on two things, how many eggs you have and how good they are. That's what a MH measures. That's what antal follicle count tells us. That's the framework most conventional for fertility care is built around an egg. Quality and quantity absolutely matter.
I'm not dismissing that, but Dr. Diana Laird. A professor of obstetrics, gynecology and reproductive sciences at UCSF and her team wanted to look deeper using cutting edge 3D imaging technology. They mapped [00:02:00] entire ovaries at the cellular level in both mice and humans, and studied nearly a hundred thousand cells across different ages.
What they found changed the picture entirely first. Eggs are not scattered randomly throughout the ovary. The way scientists assumed they're clustered in specific pockets surrounded by supporting cells, blood vessels, nerves, and connective tissue, and as the researchers put it, then environment around the egg may influence how long it last.
And how well it matures. The egg does not exist in isolation. It lives inside a community and that community matters. Second, this is the part that genuinely surprised the researchers. They discovered that the ovary is wired with sympathetic nerves, the same nerves that are involved in fight or flight response, and when those nerves were removed in mice.
Fewer eggs matured. Even though there were more [00:03:00] eggs in reserve, the nerves were helping to regulate which eggs get the signal to grow. Third, they identified a cell type in the ovaries called glia. These are support cells usually associated with a brain and the nervous system. Nobody expected to find them in the ovary, and yet there were actively participating in the ovarian environment.
And finally they found that with age. It isn't just egg numbers declining, the entire microenvironment changes, fibroblasts trigger inflammation, connective tissue scars, nerve density increase in ways that may be disrupting communication rather than supporting it. As Dr. Laird said, and I love this quote.
Ovarian aging is not just about the egg cells, but their whole ecosystem. Here's why this matters so much, especially if you've been told your egg quality or reserve is a concern. The conventional model essentially treats [00:04:00] eggs. As fixed, you have what you have, and while you cannot create new eggs, this research is showing us that the environments those eggs live in is not fixed.
It's responsive, it's dynamic, and it can be influenced. Think about a seed. Two identical seeds can have very different outcomes depending on the soil they're planted in. One soil is rich, well-nourished with good drainage and the right minerals. The other. Is depleted, dry, full of inflammation, and the seed itself hasn't changed, but the environment it's in determines everything about what it can become.
That is the ovarian ecosystem, and this research is telling us that the health of that ecosystem, the blood flow, the nerve signaling, the inflammatory environment, the supportive cells, is not just a background detail. It's central to fertility. Now, here's where Chinese medicine has been ahead of this conversation for a long time.
In [00:05:00] TCM, we do not think about fertility in terms of isolated parts. We think about the whole body as an interconnected system, and we assess the quality of that system through the lens of Qi blood, jing, and the organ networks. Let me walk you through how this maps onto what the UCSF research found. The kidneys in Chinese medicine are the root of reproductive vitality.
They store what we call jing, often translated as essence, which governs growth, development, reproduction, and aging. Jing is the deep constitutional resource. That determines the quality of our eggs, the thickness of our uterine lining, and the overall reproductive capacity. When kidney jing is depleted through chronic overwork, stress, poor sleep, nutrient deficiency, or simply the natural aging process, the entire reproductive ecosystem suffers not just the egg, the whole environment.[00:06:00]
This maps directly onto what the UCSF. Study found ovarian aging is not one thing declining. It is a system depleting across multiple cell types, tissues and signaling pathways simultaneously. That is Jing deficiency described in the language of cellular biology. In Chinese medicine, the liver stores and governs the blood and blood nourishment is fundamental to egg quality and reproductive health.
The liver also governs the smooth flow of chi throughout the body. And when liver chi stagnates, blood flow becomes compromised. Remember what the UCSF research showed about blood vessels? A companion study found that the earliest signs of ovarian aging. Began in the ovarian blood vessels, vascular aging, weakens the ovarian environment, reducing the signals and nutrients the follicles need, even when the eggs are still present.
In Chinese medicine [00:07:00] terms, this is the liver blood deficiency and liver cheese stagnation affecting the fertility ecosystem and the treatment approach. Acupuncture, blood nourishing herbs. Movement Stress regulation is specifically designed to restore that circulation. The third piece is chief flow, and here is where that UCSF finding about sympathetic nerves becomes truly remarkable.
From a Chinese medicine perspective, they found that sympathetic nerve. Fight or flight nerves are woven throughout the ovary and they regulate which eggs receive the signal to mature. When the body is in a chronic state of sympathetic activation, those nerve signals become dysregulated. The ovarian ecosystem receives confused instructions.
In TCM, the free flow of QI is what allows every system in the body to communicate clearly and function well. When Q is stagnant, particularly when there's liver chi stagnation from chronic stress, that [00:08:00] communication breaks down the follicular environment becomes less hospitable. The body is in contraction rather than expansion.
This is not metaphor. The UCSF research is showing us the cellular mechanism behind what Chinese medicine has been saying has been observing for thousands of years. So what do you actually do with this? The most important shift is this. Stop thinking about equality as the only variable infertility and start thinking about the entire ecosystem.
Ask yourself, what is the quality of the environment my eggs are living in right now? Here are the areas I focus on with my patients and online clients. The research is clear that vascular health is one of the earliest and most significant factors in ovarian aging. In Chinese medicine, we call this nourishing and moving the blood.
Practically, this looks like regular, gentle movement, walking, yoga, swimming to support [00:09:00] circulation to the reproductive organs. It means staying well hydrated. It means eating blood nourishing foods like dark, leafy greens, beets, lentils, grass fed red meat if you eat it, and deeply colored berries and acupuncture has measurable effects on blood flow to the ovaries and uterus.
This is not a claim I'm making. There is published research on this and from a TCM standpoint, it makes complete sense. Nourishing Kidney essence and Jing. This is the foundational work. Deep rests, adequate sleep, reducing the drain on your system wherever you can. Foods that support kidney Jing include bone broth.
Walnuts, black sesame seeds, kidney beans, eggs, and warming. Cooked foods that are easy to digest, and this is important. Jing is depleted by chronic stress, by pushing through exhaustion, by a nervous system that never fully rests. You cannot pour from an [00:10:00] empty vessel and you cannot nourish an ovarian ecosystem that is constantly running on empty.
Here is where the sympathetic nerve finding becomes so personally meaningful to me. The UCSF research is literally showing us that the nerves inside your ovary are involved in regulating egg maturation, and those are the same nerves that respond to chronic stress when we work on nervous system regulation through breath work.
Acupuncture mindset practices, reducing the constant state of urgency that the fertility journey can create. We are not doing something soft and peripheral. We're directly influencing the signaling environment inside the ovary. This is real. This is physiological, and it is why I am so passionate about bringing this work together.
The UCSF study found that fibroblasts in the ovaries begin triggering inflammation and scarring years before it appears in other organs. In Chinese medicine, [00:11:00] this pattern correlates with what we call heat in the blood, or accumulated stagnation, creating inflammation over time. Anti-inflammatory nutrition matters here, reducing refined sugar, processed foods, alcohol, prioritizing Omega-3 fatty acids, antioxidant rich vegetables and foods that support the liver in processing and clearing what the body no longer needs.
What I love most about this research. And why I wanted to make this video is that it challenges the fixed passive narrative that so many women receive about their fertility. You're not just a number on a lab report. Your body is not a static snapshot. Though ovarian ecosystem is alive, responsive, and in conversation with everything you eat, how you sleep, how much you move.
What your nervous system is doing all day long. Yes, age is a factor, and yes, some things are beyond our control. I will never tell you otherwise, but [00:12:00] the environment those eggs are living in, that is something you can actively, meaningfully influence. And that is worth everything. I hope this episode gave you a new way of thinking about your fertility.
One that feels less fixed and more full of possibility because that is the truth that both ancient medicine and modern science keep arriving at. The body is not broken. It's an ecosystem and ecosystems can be nourished.
