What Is Ovarian Reserve?
Ovarian reserve is frequently discussed in fertility care, but its clinical interpretation isn’t always straightforward. It provides insight into a woman’s reproductive potential by indicating how many developing follicles are available, yet egg quality and the environment in which follicles grow are just as important for fertility as the number itself.
Recent evidence increasingly suggests that diet, lifestyle and targeted supplementation can help create a more supportive environment for follicle development and overall reproductive function, even if the total number of eggs cannot be increased.
How Ovarian Reserve Is Assessed
Two commonly used markers in practice are Anti Müllerian Hormone (AMH) and Antral Follicle Count (AFC). Both are non invasive tools that help clinicians estimate ovarian reserve.
AMH reflects the pool of small, developing follicles in the ovary, while AFC is the count of small follicles visible on ultrasound. Studies confirm that AMH and AFC are reliable markers of ovarian reserve and are more predictive of ovarian response than traditional measures like FSH.
Can Nutrition and Supplements Influence Ovarian Reserve Markers?
Emerging research supports the idea that certain nutritional patterns and supplements may positively influence ovarian reserve markers. A systematic review and meta analysis from late 2025 found that nutritional supplements, including CoQ10 and other micronutrients, are associated with significantly higher AMH levels, greater AFC counts and more retrieved follicles in women with diminished ovarian reserve when taken for at least two months.
The Role of Lifestyle in Ovarian Health
Simple lifestyle changes can also support ovarian health: maintaining a healthy BMI, managing stress, moderating alcohol, and keeping up regular moderate exercise can all help create a more supportive environment for eggs to mature.
Key Takeaways for Fertility Support
• Egg quantity can’t be increased, but quality is modifiable.
• Supporting the ovarian environment through diet, supplements, and lifestyle can improve fertility outcomes.
• Even women with lower AMH or follicle counts can achieve pregnancy with the right support.
Frequently Asked Questions
-
What is ovarian reserve?
Ovarian reserve refers to the number of developing follicles in the ovaries, providing an indication of a woman’s reproductive potential.
-
How is ovarian reserve measured?
Ovarian reserve is commonly assessed using Anti Müllerian Hormone (AMH) levels and Antral Follicle Count (AFC), both of which help estimate the number of developing follicles.
-
Can egg quantity be increased?
Egg quantity cannot be increased, but the quality of eggs and the environment in which they develop can be supported.
-
Can nutrition and supplements influence ovarian reserve markers?
Research suggests that certain nutritional supplements, including CoQ10 and micronutrients, may be associated with higher AMH levels, greater AFC counts and improved follicle development when taken over time.
-
What lifestyle factors support ovarian health?
Maintaining a healthy BMI, managing stress, moderating alcohol intake and engaging in regular moderate exercise can help support a healthy ovarian environment.
-
Can women with low ovarian reserve still conceive?
Yes, even women with lower AMH levels or follicle counts can achieve pregnancy with the right support and a focus on overall reproductive health.
