Question

Quizplus · Accepted Answer

RU 486 is also known as the "abortion pill" or "mifepristone." It works by blocking the hormone progesterone, which is necessary for the endometrium to continue to support a pregnancy. Without this hormone, the endometrium breaks down and is sloughed off, causing a miscarriage. It is not effective in preventing ovulation or preventing sperm from fertilizing the egg.
