Recent research also suggests that in addition to the increased number of antral follicles in the ovary of women with PCOS, there is also an increased production of AMH by the individual follicle cells. (whitelotusclinic.ca)
Because women with PCOS typically have high numbers of antral follicles, high AMH levels are often seen as well. (verywellhealth.com)
AMH is secreted mostly by the small antral follicles in the ovary that are between 5 - 8 mm in size. (whitelotusclinic.ca)
