You’ve probably heard that the number of eggs you have decreases as you age. By the time you hit 35, things start to speed up, and the “biological clock” feels more pressing. Yet, it’s not just about how many eggs you have—quality matters too. So, what can you do to improve your egg quality?
Here’s the gist: there are some steps you can take, but let’s dig a little deeper first.
Age plays a big role in egg quality. As Dr. Anate Brauer, a reproductive endocrinologist, explains, with aging, not only do you lose eggs, but the ones you keep can develop DNA mutations. This can lead to eggs with the wrong number of chromosomes, which makes it harder for them to fertilize or implant correctly. Health issues like endometriosis and PCOS, as well as treatments like chemotherapy, can further impact egg quality. Lifestyle choices, particularly chronic stress, can also play a part, according to Dr. Brauer.
Besides DNA health, other factors matter too. The shape of the egg and how well its mitochondria—the energy sources—work are crucial. Good mitochondrial function is essential for the energy-intensive process of creating life. Age, overall health, and lifestyle choices influence how well these energy centers function.
The tricky part? There’s no straightforward test for egg quality. While tests like AMH and FSH can hint at egg quantity, they don’t reveal much about quality. “We only see quality issues when we extract the eggs and examine them,” says Dr. Brooke Rossi, another reproductive endocrinologist. Despite the uncertainty, taking steps to support egg quality might give you a sense of control amid the many factors beyond our influence.
Factors That Harm Egg Quality
Let’s look at what can harm egg quality:
- Smoking and Vaping: These habits introduce harmful chemicals into your body, which can damage cells, including eggs.
- Alcohol Consumption: Drinking excessively can lead to oxidative stress and affect overall health.
- Lack of Sleep: Poor sleep can increase stress and hormone imbalances, harming egg quality.
- Recreational Drugs: Many illicit substances can negatively impact fertility by disrupting hormonal and cellular health.
- High Sugar Intake: Excessive sugar can lead to inflammation and oxidative stress, which harms eggs over time.
A recent study published in Human Reproduction found that women who reported making positive lifestyle changes—like exercising and eating a balanced diet—saw improved reproductive health. The researchers noted a significant decrease in oxidative stress and inflammation among those women, suggesting that lifestyle can have a real impact.
In summary, while you can’t control all the factors affecting egg quality, focusing on a healthier lifestyle may help support your reproductive health. Simple changes can lead to meaningful outcomes when it comes to your fertility journey.
