The following was in the previous version: "Usually occurs in women over 30 who have carried a pregnancy to term. Conversely, it rarely occurs in women who have not carried to term."
I don't think the above is true as per: Wang, PH.; Su, WH.; Sheu, BC.; Liu, WM. (Sep 2009). "Adenomyosis and its variance: adenomyoma and female fertility.". Taiwan J Obstet Gynecol48 (3): 232–8. doi:10.1016/S1028-4559(09)60295-3. PMID19797011.Cite uses deprecated parameter |month= (help) It states "The relationship between infertility and uterine adenomyosis and/or adenomyoma is still uncertain..."
