The main clinical manifestations of adenomyosis are heavy menstrual flow and dysmenorrhea, which can be stopped clinically by taking oral contraceptives. This is due to the fact that oral contraceptives can shrink the endometrium of the adenomyotic layer, resulting in a decrease in menstrual flow. Progesterone alone can also be used because it can suppress the secretion of pituitary gonadotropins, leading to amenorrhea and metaplasia of the endometrium, mainly by taking 30 mg of medroxyprogesterone orally daily. In addition, progesterone can also be used, which has anti-estrogenic and anti-progestational effects and is usually used for three months of treatment.
