When contemplating family planning, whether actively trying to conceive or just pondering future options, having the right information is crucial. Basic infertility tests can shed light on your current fertility status. Knowing where you stand can empower you to make informed decisions about your family planning journey.
Infertility Tests: AMH and FSH Explained
For many women, the first step involves a visit to their OB/GYN for blood tests to evaluate hormone levels. A primary objective of these tests is to assess ovarian reserve—the number of eggs still available in the ovaries. Understanding your ovarian reserve can help your doctor gauge your fertility in comparison to other women of the same age.
Typically, healthcare providers will start with two key hormone measurements: follicle-stimulating hormone (FSH) and anti-Müllerian hormone (AMH). Together, FSH and AMH provide the most comprehensive insight into your ovarian reserve.
What is Follicle-Stimulating Hormone (FSH)?
FSH is produced by the pituitary gland and plays a vital role in recruiting and developing ovarian follicles, which usually contain an egg that gets released during ovulation. Testing FSH levels has long been a standard practice in infertility assessments.
As women age and the number of eggs decreases, the pituitary gland must work harder to stimulate follicle development, resulting in higher FSH levels. Elevated FSH levels, typically measured on days 2, 3, or 4 of your menstrual cycle, can indicate potential infertility.
However, FSH levels can fluctuate from month to month. Dr. Lisa Monroe, a reproductive endocrinologist, notes that relying solely on one test can be misleading. A complete assessment will consider your age, FSH, estradiol, AMH, and even an ultrasound of antral follicle count to form a comprehensive picture.
What is Anti-Müllerian Hormone (AMH)?
In recent years, the American College of Obstetricians and Gynecologists (ACOG) recommended including AMH testing alongside FSH assessments to more accurately evaluate ovarian reserve. Unlike FSH, AMH levels remain stable throughout the menstrual cycle, making them a more reliable measure.
AMH is produced by the granulosa cells that surround the small follicles in the ovaries. As the number of available eggs declines, so too does the level of AMH. High AMH levels indicate a robust ovarian reserve, while low levels suggest fewer remaining eggs.
Beyond just assessing ovarian reserve, AMH can guide treatment decisions. Dr. Monroe explains that women with higher AMH levels often respond better to ovarian stimulation, benefiting from treatments like egg freezing, intrauterine insemination (IUI), or in vitro fertilization (IVF). Conversely, lower AMH levels might indicate the need for more advanced treatments sooner.
When to Consult a Fertility Specialist
The timing for seeking help from a fertility specialist often depends on the woman’s age and how long she has been trying to conceive. For instance, if you’re under 35 and have not conceived after a year of unprotected intercourse, it’s wise to get a comprehensive fertility evaluation, including a semen analysis for your partner.
In cases where ovarian reserve appears diminished, it’s advisable to seek a fertility specialist right away, regardless of age, to maximize your chances for success. This is especially true for women interested in options like egg freezing or advanced reproductive technologies.

Summary
Infertility tests focusing on AMH and FSH levels are essential in understanding a woman’s fertility potential. Consulting with a fertility specialist can provide clarity and guidance, especially if there are concerns about ovarian reserve. Gaining insights from these tests not only empowers women in their family planning journeys but also opens the door to various fertility treatment options.
