Why does AMH fluctuate greatly and suddenly drop by half within a year? Women usually undergo ovarian AMH examination before pregnancy. If the fluctuation is large and suddenly drops, it may even decrease by half within a year, which may be caused by premature decline in ovarian function and related to factors such as living environment and ovarian damage. It is recommended that all patients seek timely medical attention, identify the cause, and then receive treatment to improve symptoms.

Amh is known as anti Mueller hormone. This value can reflect the number of sinus eggs that may be formed by the female ovaries, thus indicating the patient's reproductive ability and the start time of menopause. If the patient's AMH value is high within the normal range, it indicates more egg storage. Otherwise, the lower the value, the worse the ovarian function. However, if the value exceeds the highest value within the normal range, it indicates that the patient is likely to have polycystic ovary syndrome.

Netizens ask questions

I had a prenatal examination a year ago, but I haven't been pregnant yet. This time I went to the hospital for a physical examination and found that AMH fluctuated greatly, suddenly falling by half during this period. Does anyone know why?

The sudden low AMH value, or even a half decrease within a year, generally indicates a decrease in female ovarian reserve function, which may be caused by factors such as living environment, ovarian damage, and medication:

1. Living environment: Long term exposure to radioactive substances, frequent smoking, drinking, staying up late, etc. Can cause sudden decrease in AMH;

2. Ovarian damage: If the patient has ovarian teratoma, ovarian chocolate cyst, etc., May cause postoperative ovarian damage, leading to sudden low levels of AMH;

3. Drug factors: Some patients with ovarian diseases may be affected by drugs during drug treatment, resulting in low AMH values;

4. Other reasons: The patient's recent massive bleeding can lead to pituitary hemorrhage and ischemia, affecting the release of pituitary hormones. At this time, the AMH value will also be very low.

There is a reason for the sudden low AMH value.

Exposure to radioactive substances can lead to low AMH

The above are the factors that cause a sudden decrease in women's AMH value, but it should be noted that this hormone will gradually decrease with age. If the value shows a gradual downward trend year by year, it is a normal phenomenon, but the fluctuation is large and suddenly very low. It is recommended to go to the hospital in a timely manner.
