AMH, or anti-Müllerian hormone, is a hormone produced by the granulosa cells of the ovaries. Its concentration in the blood reflects the functional reserve of the ovaries, i.e. the number of small, developing ovarian follicles.
The AMH level is usually at its highest at the age of 20–25. The number of ovarian follicles decreases with age, which is why the AMH value provides information about the situation of the ovaries at the time of measurement.
The measurement result can be utilized in family planning and when assessing whether a more detailed investigation of fertility is needed. However, the AMH value alone does not indicate how easily a pregnancy begins or when fertility declines.
An AMH measurement provides additional information about the ovarian reserve, meaning the number of follicles in the ovaries. The measurement can be particularly useful if you want to learn more about your fertility or assess ovarian function before starting a family.
An AMH measurement may be recommended, for example, if:
Hormonal contraception and breastfeeding can also affect AMH levels. Combined hormonal contraceptives, such as birth control pills, the contraceptive ring and the contraceptive patch, can lower AMH levels, as can breastfeeding. Therefore, where possible, the test should be performed after stopping hormonal contraception and after breastfeeding has ended.
The AMH level is measured with a blood test, and it does not require fasting. The blood test is taken in the early part of a natural menstrual cycle.
The blood sample is analysed in a laboratory, and the AMH value is determined. This gives an accurate picture of the functional reserve of your ovaries.
The physician will go through the results with you at the appointment and explain their significance for your fertility. The physician will help you understand what your AMH level means.
The AMH test result will be reviewed with a physician and evaluated as part of the overall fertility picture. If the result or other information gives reason to do so, fertility can be investigated further, for example with an ultrasound scan or other hormone examinations.
If the examinations reveal factors affecting fertility, the physician will plan a suitable treatment path with you for your situation. Depending on the situation, treatment may include, for example, ovulation induction, insemination, or in vitro fertilisation.
Female fertility and its examination
Felicitas offers expert assistance in investigating female fertility. Examinations and treatment are always planned individually.
Male fertility and its examination
At Felicitas Mehiläinen, we offer expert support and comprehensive examinations for questions related to male fertility.
Reference values for AMH levels vary according to age, and there is no single "normal" value. Generally speaking, a higher AMH level indicates a better ovarian reserve. A physician always interprets the results individually and relates them to your age and situation.
A low AMH level can indicate that the ovarian functional reserve has decreased. However, it does not mean that a pregnancy cannot start. A physician evaluates the significance of the result as a whole and, if necessary, recommends other examinations or discusses options for starting a family.
A high AMH value usually indicates a greater number of small ovarian follicles. An elevated value can be seen, for example, in polycystic ovaries (PCOS). However, the AMH value alone is not sufficient for diagnosing PCOS; instead, the situation is assessed on the basis of other symptoms, findings, and examinations.
The AMH level may be falsely low due to the use of contraceptives or breastfeeding. It is therefore important to follow the preparation instructions before sample collection.
The AMH level indicates the functional reserve of the ovaries, but alone it does not indicate how long fertility will last or how easily pregnancy begins. The result is assessed together with age, other examinations and life situation.
