In recent years, more and more women have postponed pregnancy planning until after the age of 30. When they finally begin preparing for pregnancy, they are often surprised to see the words "diminished ovarian reserve" on their medical reports. For those exploring U.S., Mexico, and Japan IVF or U.S., Mexico, and Japan egg freezing, this has become one of the most common questions raised during fertility consultations.

 

What Is Diminished Ovarian Reserve?

 

Ovarian reserve reflects the number of follicles remaining in the ovaries and their potential to develop into mature eggs. A woman is born with a fixed number of follicles, and this supply gradually declines with age in an irreversible process. In general, ovarian reserve begins to decrease more rapidly after the age of 35, declines even more noticeably after 40, and natural conception becomes significantly less likely around the age of 45.

 

It is important to understand that diminished ovarian reserve is not limited to older women. Genetic factors, ovarian surgery, endometriosis, autoimmune diseases, chemotherapy, radiotherapy, and certain medications may also lead to an earlier decline in ovarian function. As a result, younger women may also experience this condition.

 

How Can You Assess Your Ovarian Reserve?

 

Several common tests are currently used to evaluate ovarian reserve.

 

AMH (Anti-Müllerian Hormone) is one of the most widely used indicators because it provides a relatively stable estimate of the number of remaining follicles. Antral Follicle Count (AFC), measured by ultrasound, is another important reference for assessing ovarian reserve. In addition, testing hormone levels such as FSH on days 2 to 3 of the menstrual cycle helps physicians make a comprehensive evaluation of ovarian function.

 

Generally, women under the age of 35 have approximately 8 to 12 antral follicles across both ovaries. A significantly lower AFC or persistently low AMH level may indicate diminished ovarian reserve, requiring further evaluation based on age, menstrual history, and overall reproductive plans.

 

Can You Still Get Pregnant with Diminished Ovarian Reserve?

 

Many people mistakenly believe that diminished ovarian reserve means pregnancy is no longer possible.

 

In reality, diminished ovarian reserve mainly indicates a reduced number of available eggs, not the complete absence of eggs. Some women still have the opportunity to conceive naturally. For those hoping to improve their chances of success, assisted reproductive technology can provide additional options.

 

In recent years, U.S., Mexico, and Japan IVF has continued to advance, with increasingly sophisticated ovarian stimulation protocols, laboratory culture systems, and embryo management. For women with diminished ovarian reserve, physicians develop individualized stimulation strategies based on factors such as age, AMH level, and antral follicle count, aiming to retrieve more high-quality eggs and improve the overall efficiency of treatment.
