Risk factors for adenomyosis include:

  • Prior uterine surgery, such as a C-section or fibroid removal
  • Childbirth
  • Middle age

Most cases of adenomyosis, which depends on estrogen, are found in women in their 40s and 50s, with a low incidence after menopause. Finding adenomyosis in middle-aged women could relate to longer exposure to estrogen compared with that of younger women.
