This review article aims to summarize current tools used in the diagnosis of adenomyosis with relative pharmacological and surgical treatment and to clarify the relative association between adenomyosis and infertility, considering the importance of an accurate diagnosis of this heterogeneous disease. Among different reported concepts, direction invagination of gland cells from the basalis endometrium deep into the myometrium is the most widely accepted opinion on the development of adenomyosis. Adenomyosis has been increasingly identified in young women with pain, AUB, infertility, or no symptoms by using imaging techniques such as transvaginal ultrasound and magnetic resonance. Furthermore, adenomyosis often coexists with other gynecological conditions, such as endometriosis and uterine fibroids, increasing the heterogeneity of available data. However, there is no agreement on the definition and classification of adenomyotic lesions from both the histopathology and the imaging points of view, and diagnosis remains difficult and unclear. A standard, universally accepted classification system needs to be implemented to improve our understanding and inform precise diagnosis of the type of adenomyosis. This could be the key to designing RCT studies and evaluating the impact of adenomyosis on quality of life in terms of menstrual symptoms, fertility, and pregnancy outcome, given the high risk of miscarriage and obstetric complications.
