It turns out youth isn’t the only asset!
Ovarian age testing is the best indicator for evaluating egg reserves. Loving yourself starts with understanding yourself!
What is AMH (Anti-Müllerian Hormone)?
In recent years, AMH has increasingly been used to assess fertility potential. It is an important factor affecting the success of pregnancy and IVF! A higher AMH value means a larger ovarian reserve. We can estimate the number of eggs that can be retrieved during IVF based on this number, which is closely related to the success rate! However, AMH decreases with age—especially after 35, the value drops rapidly and significantly, and right before menopause, it can approach zero!
Therefore, it is recommended that all adult women have a blood test to measure their AMH. The value does not fluctuate with the menstrual cycle, so it can be tested at any time!
If you haven’t tested your AMH yet—book now!
What is the relationship between AMH and egg quantity?
AMH is secreted by granulosa cells of small to medium immature follicles in the ovary. The more small follicles present, the higher the AMH level, indicating a potentially greater egg reserve. In animal studies with mice, AMH was found to regulate the number of primordial follicles developing into primary follicles. Mice lacking AMH quickly exhausted their egg supply and entered early menopause. It is therefore inferred that AMH plays a role in suppressing premature follicle maturation in humans—higher AMH means more follicles are being held in reserve, reflecting higher ovarian capacity.
AMH is comparable to the antral follicle count (AFC) obtained via ultrasound, but more convenient since AMH levels in blood do not vary with menstrual cycle timing. The amount of AMH is closely tied to the number of eggs retrieved during IVF, which directly affects success rates. AMH is now regarded as the best test for evaluating ovarian function and egg reserve in women.
What is the relationship between AMH and age?
AMH levels decline with age and become undetectable by menopause. Although reference ranges for Taiwanese women are still lacking, a 2016 study by Du X. et al. using data from 1509 Chinese women found average AMH values and the 5th–95th percentile range by age group (unit: ng/mL).
Why should you test your AMH?
With ongoing research, AMH is being widely used in clinical applications:
- Evaluate the ovarian reserve of women of reproductive age.
- Assess female fertility potential.
- Predict the risk of premature ovarian failure.
- Predict polycystic ovary syndrome (PCOS).
- Predict the effectiveness of ovarian stimulation in IVF.
- Predict the success rate of IVF treatment.
- Predict the onset of menopause or perimenopause.
- Predict ovarian damage before or after surgery or chemotherapy.
Women concerned about fertility should understand their own bodies. AMH is the most convenient and effective tool for assessing ovarian function.
