If a woman wants to check her ovarian reserve function, she usually needs two tests: 1) Hormone 6 to see if there are any abnormalities in estrogen, progesterone and luteinizing hormone, etc. 2) Anti-Mullerian hormone, which is the most critical test to reflect ovarian reserve function. If the anti-Mullerian hormone is too low and does not correspond to the age, it is considered that the ovarian reserve function is declining and fertility is significantly reduced. If the anti-Mullerian hormone is particularly low, it is usually very difficult to get pregnant because it means that the number of eggs that can be developed in the ovaries is particularly low, but the hormone 6 can also assist in diagnosing the reserve function of the ovaries.
