Pregnancy does not cause low AMH. AMH refers to anti-Müllerian hormone, a glycoprotein secreted by the granulosa cells of small follicles. It is an important indicator for assessing a woman’s ovarian reserve function and does not usually change significantly during pregnancy.
The level of AMH is directly related to the number of follicles. Its value is relatively stable and does not change significantly with the menstrual cycle, so it can be used to assess a woman’s ovarian reserve function. In women, AMH values are expressed during fetal life, increase in secretion during infancy, peak during puberty, and gradually decrease with age.
When the AMH value is low, it is recommended to follow the doctor’s instructions to conduct further relevant examinations, to clarify the cause with the help of the doctor, and to standardize the treatment.
