Adenomyosis is often associated with all of the following except :

e. Subinvolution of uterus

Adenomyosis is commonly associated with conditions such as endometrial hyperplasia, myomas (fibroids), endometriosis, and myometrial hypertrophy, but not typically with subinvolution of the uterus. Subinvolution of the uterus generally refers to incomplete return of the uterus to its pre-pregnancy size after childbirth, which is not directly related to adenomyosis.
