In women with adenomyosis, the endometrium and glands periodically invade the myometrium, causing progressive menstrual cramps that can lead to a gradual increase in the size of the uterine tumor, which can affect the embryonic implantation and make pregnancy difficult. For women with adenomyosis, the chance of pregnancy is generally around 60%, and about 40% of adenomyosis patients are unable to conceive naturally and need to consider IVF, even if IVF is not successful in conception. Once pregnant, adenomyosis will not gradually worsen, but may gradually decrease, because after pregnancy, the ovaries will continue to secrete estrogen and progesterone, and lead to physiological amenorrhea, so the endometrium will not shed periodically, which will not cause adenomyosis to worsen.
