The cannula is attached to a syringe, which is used to aspirate the uterine contents and induce the onset of the “missed period.” This technique is not always effective, and sometimes a second procedure is required. It should be done within two weeks of a missed menstrual period.

menstrual extractionFringe obstetrics
A type of abortion that consists of the suction extraction of an early (up to 8 weeks of gestation) conceptus, often performed by lay persons. While somewhat similar to an abortion performed by a physician, the procedure is not without danger and women so treated may not seek timely medical intervention when needed. As the data are anecdotal, claims for menstrual extraction’s success may be exaggerated and the real or potential complications (uterine perforation, ectopic pregnancy, gram-negative sepsis and continued pregnancy) minimised by its advocates.
