Can adenomyosis cause miscarriage?

Adenomyosis can be associated with a higher risk of pregnancy complications, and it may contribute to miscarriage for some patients—but it’s not a guarantee, and many people with adenomyosis go on to have healthy pregnancies. The reason it can matter is that adenomyosis changes the uterine muscle and uterine environment, which may affect implantation and early placental development through inflammation and abnormal uterine contractions.

Risk isn’t the same for everyone. Outcomes often depend on the pattern of disease (focal adenomyoma versus diffuse adenomyosis), how much of the uterine wall/junctional zone is affected, and whether adenomyosis overlaps with endometriosis—which is common and can compound fertility and pregnancy challenges. If you’ve experienced infertility, recurrent pregnancy loss, or repeated implantation failure, our team can help evaluate whether adenomyosis (and coexisting endometriosis) may be part of the picture and walk you through fertility-sparing options, including when surgery to remove a focal adenomyoma may be realistic versus when other approaches make more sense.
