Which of the following is a known risk factor for adenomyosis?

Adenomyosis is a condition characterized by the presence of endometrial tissue within the muscular wall of the uterus, and its risk factors have been extensively studied. One of the recognized risk factors is increased parity or having multiple births. This correlation may be attributed to the physical changes and repeated trauma experienced by the uterine tissue during pregnancies and childbirth, which can lead to the development of adenomyosis over time.

Increased parity suggests that women who have had multiple pregnancies may have a greater likelihood of experiencing the hormonal and mechanical stresses that contribute to the condition. Therefore, as the number of pregnancies increases, the risk of developing adenomyosis may also rise.

Understanding this association is crucial for healthcare professionals when assessing patients who present with symptoms potentially related to adenomyosis, as their obstetric history can provide important insights into their risk profile.
