When talking about fertility, one of the first questions is usually: how many eggs do I have?
For years, the conversation has focused on quantity, especially through tests such as Anti-Müllerian Hormone or follicle count. However, there is a key point that is not always explained with the same clarity.
It is not just about how many eggs you have, but how capable those eggs are of leading to a pregnancy.
That is where a fundamental concept comes in: egg quality.
What does egg quality really mean?
Egg quality is not something that can be directly seen in an ultrasound or a basic test.
It refers to the biological ability of an egg to successfully complete the reproductive process. In other words, for an egg to be fertilized, develop properly, form a viable embryo, and ultimately lead to a pregnancy.
One of the most important aspects of this quality is genetic integrity. When an egg has chromosomal abnormalities, embryo development can be affected from very early stages.
This is why, even if it is not always visible, quality is one of the factors that most directly impacts the final outcome.
Quantity is not the same as probability
Having a good ovarian reserve is positive. It means there is an adequate number of eggs available.
However, this does not guarantee pregnancy.
In clinical practice, it is common to see patients with an apparently favorable reserve who still face difficulty achieving pregnancy. The opposite can also happen, women with fewer eggs but better chances due to their quality.
In fertility, more does not always mean better.
This is one of the most important shifts in how reproductive health is understood today.
The factor that most influences egg quality
Egg quality is directly related to age.
Over time, eggs not only decrease in number, but also undergo internal changes, especially at the chromosomal level. This increases the likelihood of embryos having abnormalities that may prevent proper development or implantation.
As age increases, it is also common to see:
- A higher risk of chromosomal abnormalities in embryos
- A decrease in pregnancy rates
- An increase in the likelihood of miscarriage
This is a natural process, but it is not always considered when planning when to try to have a baby.
What basic tests do not show
One of the biggest challenges when talking about egg quality is that it is not directly measured in initial testing.
Tests such as AMH or ultrasound can estimate the number of eggs, but not their actual potential to lead to pregnancy.
This explains why many patients have “normal” test results and still face difficulties.
Egg quality is not always visible, but it becomes evident in the outcomes.
When pregnancy does not occur, when implantation fails, or when embryos do not develop as expected, it becomes necessary to look beyond basic evaluations.
When pregnancy does not happen: the role of egg quality
In many cases, difficulty achieving pregnancy does not have an obvious cause in early testing.
However, when analyzed more deeply, egg quality is often involved.
This can present as:
- Low fertilization rates
- Embryos that do not develop properly
- Repeated implantation failure
- Early pregnancy loss
These patterns are not always identified in a first attempt, but when they repeat, they indicate the need for a different approach.
Can egg quality be improved?
This is one of the most common and also most complex questions.
Age cannot be changed, but there are factors that influence the environment in which eggs develop.
Elements such as metabolic health, hormonal balance, and inflammation can impact egg quality.
That is why the approach today goes beyond measuring ovarian reserve.
At Ingenes, the focus includes working on the full context in which the reproductive process occurs, aiming to optimize the conditions that may influence egg quality.
In addition, reproductive medicine allows for more informed decision making through tools that evaluate embryo development and genetic information.
This does not change the original quality, but it does allow a more precise identification of which embryos have the highest potential.
The importance of embryo selection
One of the most important advances in assisted reproduction is the ability to analyze embryos before transfer.
Through genetic testing, it is possible to identify which embryos have a normal chromosomal structure and therefore a higher chance of developing properly.
This is especially relevant in cases where egg quality may be a factor.
Because it helps reduce uncertainty and move forward with greater clarity in each attempt.
At Ingenes, these tools are integrated into a broader strategy, where each decision is based on meaningful data.
When the strategy changes, the outcome changes
One of the most common mistakes is repeating the same approach expecting a different result.
But when egg quality is a factor, this rarely works.
It becomes necessary to adjust the strategy, analyze more deeply, and make decisions based on what is actually happening.
At Ingenes, this shift allows moving from general attempts to personalized strategies, where each step has a clear purpose.
And that difference is critical.
Beyond the number: understanding your fertility
Reducing fertility to a single indicator can lead to incomplete conclusions.
The number of eggs is only part of the picture.
Quality is what defines real potential.
That is why understanding your fertility requires looking at the full process, not just one data point.
Ingenes: seeing beyond what is visible
At Ingenes, the approach goes beyond measuring.
It is about understanding.
Evaluating egg quality, embryo development, genetics, and the environment in which the process takes place allows for a much clearer view of each case.
From there, a strategy that truly makes sense can be defined.
Because it is not just about how many eggs there are.
It is about understanding what can be achieved with them.
Conclusion
In fertility, the number of eggs matters, but it is quality that truly defines the chances of achieving pregnancy.
That is why, beyond the numbers, it is essential to understand what is happening in each case and how it can be approached in a comprehensive way.
At Ingenes, this analysis helps identify what is not always visible and define a clearer, more personalized path with better chances of achieving your goal of having a baby.
