Maftolone is a short-acting contraceptive pill consisting of small doses of estrogen and progestin. The effect of Momfoolone on the uterus comes from the action of estrogen and progestin on the uterus. With regular use of short-acting contraceptives, regular proliferation and exfoliation of the endometrium can occur, which helps to inhibit the growth of the overproliferated endometrium as well as to promote the growth of the thin endometrium caused by multiple abortions or purging procedures. That is, taking Mafulon can balance the degree of endometrial hyperplasia. This action of Mafulon can be used to regulate menstruation and maintain the menstrual cycle, period and volume at a reasonable level. Regular use of Mafulon is also effective in relieving the symptoms of primary dysmenorrhea.
