The uterine appendages (or adnexa of uterus) are the structures most closely related structurally and functionally to the uterus.

They can be defined in slightly different ways:

• Some sources define the adnexa as the fallopian tubes and ovaries.^[1]
• Others include the supporting tissues".^[2]
• Another source defines the appendages as the "regions of the true pelvis posterior to the broad ligaments".^[3]
• One dictionary includes the fallopian tubes, ovaries, and ligaments (without specifying precisely which ligaments are included).^[4]

The term "adnexitis" is sometimes used to describe an inflammation of the uterine appendages (adnexa).^[5] In this context, it replaces the terms oophoritis and salpingitis.

The term adnexal mass is sometimes used when the location of a uterine mass is not yet more precisely known.

63% of ectopic pregnancies present with an adnexal mass. Depending on the size of the mass, it could be a medical emergency.

The term "adnexectomy" in gynaecology is often used for salpingo-oophorectomy (removal of both: fallopian tubes and ovaries).
