What Is Egg Quality and Why Does It Matter?
A simple guide to understanding egg quality, fertility, IVF success, miscarriage risk, and the 90-day window for supporting healthier eggs.
Egg quality plays a major role in fertility, embryo development, implantation, and miscarriage risk and while we can’t change age, we can support the environment your eggs are developing in.
If you've been trying to get pregnant for a while, you've probably heard the term "egg quality" over and over again.
Your fertility clinic talks about it.
Women in Facebook groups talk about it.
Every fertility article seems to talk about it.
Yet despite how often it's discussed, most women don't actually get a clear explanation of what egg quality means, why it matters or if they can improve theirs.
I can't tell you how many women come to me feeling completely defeated because they've been told their AMH is low, they are getting older, or their IVF cycle didn't go as planned. Many have already convinced themselves that they have "bad eggs" and that there's nothing they can do.
They're scared.
They're frustrated.
And most importantly, they're making assumptions about their fertility based on incomplete information.
The reality is much more nuanced than that.
Understanding egg quality is important, but understanding what it does and does not tell us about your fertility is even more important.
Can what I eat help me get pregnant?
What Is Egg Quality?
Egg quality refers to the health of an egg and its ability to create a healthy embryo.
For an egg to result in a healthy pregnancy, a lot has to happen behind the scenes. The egg needs the correct number of chromosomes, enough energy to support fertilization and embryo development, and the ability to continue growing after implantation.
When egg quality is strong, the chances of creating a healthy embryo are higher.
When egg quality is compromised, the process can break down at different stages. Fertilization may not occur, embryos may stop developing, implantation may fail, or pregnancy loss may occur.
One thing I want women to understand is that egg quality is not a reflection of how hard you've worked, how badly you want a baby, or whether you've done something wrong.
Many of the women I work with have spent years doing everything they can to support their fertility. They've changed their diet, taken supplements, exercised, gone through fertility treatments, and advocated for themselves every step of the way.
Yet they still find themselves asking, "Why isn't this working?"
Sometimes egg quality is part of the answer. But it is rarely the entire answer.
Egg Quality vs. Egg Quantity
This is where a lot of confusion happens.
Almost every week I speak with women who have been told their AMH is low and immediately assume that means their egg quality must also be poor.
Those are two completely different things.
Egg quantity refers to how many eggs you have remaining, also known as your ovarian reserve.
Doctors typically use tests such as:
AMH (Anti-Müllerian Hormone)
AFC (Antral Follicle Count)
FSH (Follicle Stimulating Hormone)
to estimate egg quantity.
Egg quality is different.
It refers to how healthy those eggs are.
And here's something I wish more women were told early in their fertility journey:
There is no blood test that can directly measure egg quality.
That's why I get concerned when women are given a low AMH result and leave the appointment believing they can never get pregnant.
I've worked with women who were devastated after being told their AMH was low. Some had already started grieving the family they hoped to have.
Then we looked at the bigger picture.
We reviewed their health history.
We identified factors affecting their fertility.
We created a strategy.
And many of those women went on to create healthy embryos, successful IVF cycles, and healthy pregnancies.
Does low AMH matter?
Of course it does.
But low AMH does not automatically mean poor egg quality, and it certainly does not tell the whole story.
You can have a low AMH and still produce healthy eggs.
You can have a normal AMH and struggle with embryo development.
You can retrieve a large number of eggs during IVF and still have challenges creating genetically normal embryos.
This is why I always encourage women to stop obsessing over a single number and start looking at the full picture.
Fertility is rarely about one lab result.
It's about understanding all of the factors influencing your reproductive health and creating a plan that gives you the best possible chance of success.
Supporting Your Egg Quality
The good news is that egg quality is not something you have to feel completely powerless over. The 90 days before ovulation matter, and there are meaningful changes you can make with your nutrition, supplements, sleep, lifestyle, and overall fertility strategy.
