When it comes to predicting fertility, a person’s clinical history—along with that of their close relatives—can provide valuable insights. For instance, how long a couple has been trying to conceive can indicate fertility levels; the longer the attempt, the lower the fertility rate typically is. Another important aspect is the response to ovarian stimulation, which tends to be consistent across cycles. Additionally, family factors, like the fertility history of a woman’s mother or sisters, reflected in their ages at menopause and conception, can also be telling.
The Role of Ultrasound in Assessing Ovarian Reserve
Ultrasound plays a crucial role in assessing ovarian reserve, specifically through the Antral Follicle Count (AFC). These smaller follicles, visible on ultrasound and measuring between 2 and 10 mm, decline in number as a woman ages. Younger women usually have an AFC of 10-20, but this number drops by about 5% every year until age 37, and then the decline accelerates to around 10% per year after that. While a higher AFC suggests a better response to fertility medications, its ability to predict pregnancy outcomes, especially in cases of low AFC, is limited.
Understanding the Anti-Mullerian Hormone (AMH) Test
Another significant predictor is the Anti-Mullerian Hormone (AMH) test. This blood test measures ovarian reserve directly, with higher levels (over 1.0) indicating better reserve. AMH is considered one of the most reliable indicators of both ovarian age and the onset of menopause, and it can even help predict complications from treatments like chemotherapy or the effects of conditions like PCOS. Unlike some other tests, AMH can be measured at any point in the menstrual cycle and is unaffected by hormonal treatments.
Other Relevant Tests
Other tests like cycle day three FSH and estradiol levels, as well as the clomiphene challenge test, are still relevant in estimating ovarian reserve. However, they are not foolproof predictors of pregnancy rates. They can aid in screening and counseling but are not definitive in determining a woman’s ability to conceive.
The True Measure of Ovarian Reserve
Ultimately, the best measure of ovarian reserve is the response to treatment and whether a pregnancy results from that treatment. As research evolves, we’ll continue to explore the effectiveness of various ovarian reserve testing methods.

In summary, understanding ovarian reserve involves a mix of clinical history, ultrasound assessments, and blood tests. While these predictors can guide treatment options, they are not definitive. The true test lies in how well a person responds to treatment and the outcomes that follow.
