If you’re wondering where your fertility stands—now or for the future—you’re not alone. At MCRM Fertility, we believe that understanding egg quality and quantity (a.k.a. your ovarian reserve) can help you make clear, confident choices about trying to conceive today or preserving options for tomorrow.
In simple terms, quantity is how many eggs you still have; quality is how likely those eggs are to develop normally after fertilization. Both matter, and both can be understood—with care, context, and a plan that fits your life.
What Is Egg Quantity?
People who produce eggs—women and those assigned female at birth (AFAB)—are born with a finite number of them. That number gradually declines over time—first slowly, then more quickly in the late 30s. This is called diminished ovarian reserve, and it’s a normal part of biology, not something you “did wrong.”
To get a clearer view of your current egg quantity, an MCRM fertility specialist may recommend tests like:
- AMH (Anti-Müllerian Hormone): a sensitive blood test reflecting the number of small follicles in your ovaries.
- FSH and Estradiol (E2): day-2 to day-4 bloodwork that helps assess ovarian responsiveness.
- Antral Follicle Count (AFC): a quick ultrasound that counts small resting follicles.
These tests don’t “predict the future,” but they do offer a snapshot that guides decisions—like continuing to try naturally, adjusting timing, or considering egg freezing.
What Is Egg Quality?
Egg quality is about the health of your eggs, especially their chromosomes. As we age, a higher proportion of eggs may be aneuploid (chromosomally abnormal), which can make fertilization, embryo development, and implantation harder and can raise the chance of miscarriage. Age remains the most reliable indicator of egg quality.
The American Society for Reproductive Medicine (ASRM) notes that while fertility declines with age, the change becomes more noticeable after 35; by 40, relative fertility is about half of what it is in the late 20s to early 30s.*
That’s big-picture guidance meant to inform—not alarm—and it’s one reason timely information can be so helpful. If you’re not ready to try now, egg freezing can preserve today’s egg quality for a future attempt—giving you back some control over timing.
Numbers aren’t everything. People with modest ovarian reserve sometimes produce beautiful, healthy embryos. Others with robust numbers may still face hurdles. Your story is yours—data informs the plan; it doesn’t define your outcome or your worth.
How Egg Quality and Quantity Work Together
Think of egg quantity as how many lottery tickets you can buy in a given cycle, and egg quality as how many of those tickets have the right numbers. More eggs can increase chances, but one excellent egg can be enough. This is why your care plan considers both—plus your age, medical history, and goals.
Can You Improve Egg Quality?
You can’t increase the number of eggs you have, but you can support your overall reproductive health and the environment your eggs develop in. Evidence suggests it’s helpful to avoid smoking, limit alcohol and high caffeine, and be mindful of endocrine-disrupting chemicals (for example, choosing glass or stainless containers and fragrance-free products when possible).
Many people also choose to take a daily prenatal with folic acid, and may discuss CoQ10 or vitamin D with their provider. Supplements aren’t magic, but they can support cell energy and general wellness.
Testing Your Egg Quality and Quantity at MCRM Fertility
Our approach pairs clear testing with compassionate coaching. We’ll explain what AMH, FSH/E2, and AFC mean (and what they don’t), answer your questions, and map next steps with you.
ASRM’s guidance emphasizes that markers like AMH and AFC are most useful for predicting oocyte yield in IVF—not your exact chance of natural pregnancy.** Age still carries the most weight, and your plan should reflect that reality while honoring your preferences and timeline.
Frequently Asked Questions
How often should I check my ovarian reserve?
If you’re under 35 and not actively building your family yet, checking every couple of years is reasonable. If you’re 35+ or considering egg freezing, yearly AMH/AFC can help you track trends. Your provider will personalize the cadence based on your goals.
What’s the difference between diminished ovarian reserve and poor egg quality?
Diminished ovarian reserve (DOR) means fewer eggs remain. Egg quality describes how likely those eggs are to be chromosomally normal. They can change at different rates—some people have fewer eggs but good quality, and vice versa.
Can treatment help if my numbers aren’t ideal?
While we can’t reverse age, treatments can optimize odds. IVF can recruit multiple eggs in one cycle; embryo testing (PGT) can help identify embryos with the right number of chromosomes; and tailored protocols can improve comfort and efficiency. For those not ready yet, egg freezing preserves today’s quality for tomorrow.
