Adenomyosis can lead to a natural pregnancy if it occurs at an early stage, and also at a later stage, but the chances of getting pregnant will be smaller. 1. Early stage of adenomyosis: the physiological function of the uterine lining is not much affected, and you can usually get pregnant naturally, but after pregnancy, with the gradual increase in the secretion of estrogen in the body, it may lead to the aggravation of the condition of adenomyosis, which is prone to miscarriage or preterm labor, and so on. 2. Late stage of adenomyosis: If adenomyosis is more serious in the late stage, it may cause the uterus to enlarge and harden, which will have a greater impact on pregnancy and make it not easy to get pregnant. Therefore, when adenomyosis is present before pregnancy, it is better for both the woman and the fetus to have early and active treatment before pregnancy.
