There are two methods of abortion, one is medical abortion and the other is human abortion, which is less harmful to the human body because human abortion is to expel the embryo out of the body through surgical methods, while medical abortion is to expel the embryo out of the body through the use of contractions of the patient’s own body after taking medicine. However, there is a certain failure rate of medical abortion, after the failure of medical abortion, it is necessary to terminate the pregnancy by scraping the uterus to scrape the embryo or intrauterine tissue out of the body. Through clinical observation, the average bleeding time after medical abortion is longer than that of human abortion, so the harm to the human body is greater than that of human abortion.
