Mafolone is a short-acting contraceptive pill that inhibits ovulation and changes the thickness of the endometrium, causing it to shrink and thin, and then prevents the fertilized egg from being laid, thus achieving the goal of contraception. Due to individual differences, it is possible that oral administration of Mafron may not prevent ovulation and pregnancy may occur in clinical practice. In addition, the thickness of the endometrium does not change to a thickness that prevents the fertilized egg from being laid, and pregnancy may also occur. Mafron can be 98% effective, but 2% of people will still get pregnant while taking the pill. Mafron has some side effects, such as blemishes on the face, weight gain and weight gain due to water and sodium retention, and menstrual disorders.
