The AMH test can be performed on any day of the menstrual cycle.
If you require a comprehensive female reproductive hormone panel (including FSH, LH, E2, etc.), it is recommended to have the test between days 2 – 5 of the menstrual cycle to ensure the most accurate results.
Fasting is not required before the AMH test, but you should take note of the following:
- Do not discontinue oral contraceptives prior to AMH testing without the explicit recommendation of a specialist. It is essential to inform DIAG about any contraceptive medications you are currently using. This is because certain combined hormonal contraceptives may lead to an underestimation of ovarian reserve. Your physician will interpret the AMH results more accurately by considering your contraceptive history in conjunction with the laboratory findings.
- Inform DIAG if you are taking high-dose biotin (vitamin B7). You will be given specific instructions to properly prepare for the AMH test in accordance with the test requirements.
Yes. Low AMH levels can still allow for natural pregnancy if the ovaries are functioning and ovulation is occurring. However, it may take longer to conceive.
This decision depends on your age and how long you have been trying to conceive:
- Under 35 years old and have not been trying for long (just started or only a few months): Your doctor may recommend continuing to try naturally for another 6 – 12 months as there is still a reasonable chance of conceiving without immediately resorting to IVF.
- 35 years or older, or have been trying for a long time without success (typically over 6 – 12 months): It is advisable to discuss IVF or other assisted reproductive techniques with your doctor as soon as possible since ovarian reserve declines rapidly over time.
Currently, there is no widely available and effective medical method to increase the number of ovarian follicles. However, you can optimize egg quality and improve your chances of conception through the following measures:
Maintain a healthy weight, with a Body Mass Index (BMI) between 18.5 and 22.9.
- Follow a diet rich in vegetabes, berries, and fatty fish (rich in omega-3).
- Use supplement with vitamin D, Coenzyme Q10, folic acid as advised by your doctor.
- Limit alcohol consumption and avoid smoking.
- Avoid exposure to harmful chemicals and toxins.
- Screen for and treat gynecological conditions early, such as infections, fibroids, endometriosis, etc.
- Consider early egg freezing if you do not plan to become pregnant in the near future.
High AMH is not always a good thing. If AMH levels are above the safe threshold, it may be associated with polycystic ovary syndrome (PCOS), ovulation disorders, and an increased risk of ovarian hyperstimulation during fertility treatments.
If AMH is high but your menstrual cycle is regular and there are no abnormal symptoms, treatment is not necessary.
If high AMH is accompanied by ovulation disorders, excessive hair growth, acne or difficulty conceiving, treatment may be required as it is often related to PCOS.
You should retest for AMH every 6 months if you are planning to conceive, undergoing infertility monitoring, have ovarian conditions, have had surgery affecting ovarian reserve, or as advised by your specialist doctor.
