What’s Your Number?
For most women, age best predicts the chance of conception each month. However, despite having regular menstrual cycles and normal periods, many women will lose their fertility sooner than expected. There are several tests which help predict whether a woman may have a faster biological clock, such as Anti-Mullerian Hormone Test (AMH). This blood test helps to estimate what is called “ovarian reserve” by measuring the number of follicles capable of developing in the future.
Houston Fertility Institute is excited to announce that we are hosting a free AMH Screening Event at our Woman’s Hospital office. In order to educate and help inform our patients of what this event is all about – we called on one of our amazing docs to help us by answering some questions about what exactly an AMH test is.
What is AMH?
Dr. Ryan Steward – Anti-Mullerian hormone (AMH) is secreted by primordial, or immature, follicles in the ovary. Each follicle typically contains an egg capable of being ovulated during a future menstrual cycle. Women are born with all the eggs they will ever have and this number deceases over time until menopause. Therefore, as the number of primordial follicles (eggs) deceases with age, so does the AMH level.
What does this test tell us?
Dr Ryan Steward – This test, combined with others, such as the number of small follicles in each ovary at the beginning of the menstrual cycle (antral follicle count), provides an indication of the ovarian reserve, or the number of eggs a woman has remaining. Thus, AMH suggests one measure of a woman’s fertility potential compared to others her age.
What does this mean for a woman’s fertility options?
Dr. Ryan Steward – While is it not a perfect test and no one assay is universally accepted, values that are low or high suggest abnormality and help plan treatment. Patients with low Anti-Mullerian hormone, particularly those over 35 years of age, may benefit from more aggressive treatment. Those with high AMH typically have some degree of ovulatory dysfunction. In both cases, the AMH level serves as a marker for ovarian response to fertility medications and thus helps guide dosing.
Please call 713-796-9888 for more information or to reserve your spot. Dr. Ryan Steward will be present at the event. He can answer your questions about AMH, fertility in general, or questions more tailored to your specific case. This Anti-Mullerian Hormone Test is recommended for females age 25 – 45 and is free of charge to all that attend this exciting event.
Dr. Steward received his medical degree from University of Texas Health Science Center at San Antonio and has completed a fellowship in Reproductive Endocrinology and Infertility at Duke University. Dr. Steward is seeing patients at our Medical Center – Woman’s Hospital and Woodlands locations.
