Manual vacuum aspiration (MVA) is a method of emptying the womb using a large syringe and cannula. It can be used for various purposes, such as ending an unwanted pregnancy, helping a woman who has had an incomplete miscarriage or abortion, or regulating monthly bleeding. MVA is a fast and safe way to evacuate the content of the uterus using negative pressure. It avoids trauma of the cervix and the endometrium.
