Both adenomyosis and endometriosis involve the growth of endometrial-like tissue outside the uterus, but there are key differences:
- Adenomyosis occurs when the tissue grows into the muscular wall of the uterus.
- Endometriosis occurs when the tissue grows outside the uterus, on other organs in the pelvic region (e.g., ovaries, fallopian tubes, and the outer surface of the uterus).
Both conditions can cause pelvic pain, heavy periods, and infertility, but their causes, symptoms, and treatments can vary.
