World Contraception Day is celebrated every year on September 26, not that contraception is necessary on this day, but rather that the focus is on promoting contraception on this day. Looking back on several years of science writing, it is true that more or less involved in the matter of contraception, especially the issue of emergency contraceptive pills I have to continue to talk about the frequency of use of the pill. When it comes to emergency contraceptives, it is a “dead sheep mending” move, the shepherd in order to keep most of the sheep, if he repeatedly, again and again to “dead sheep mending”, it is estimated that he is not a good shepherd, sooner or later will be the tragic end of the entire flock. So the only way to ensure the harvest and income of the family is to do a good job of stabilizing the sheep pen in advance and to make frequent inspections. So if a woman asks me, “Doctor, can I take the emergency contraceptive pill regularly?” I will tell her this old idiom story. The main mechanism of action of the emergency contraceptive pill is to inhibit ovulation. The human body is an amazing structure, and ovulation does not depend on the ovaries alone, but requires the brain to give orders. If we occasionally suspend the work of the command via the pill, and the ovaries stop ovulating, there will be at most a disruption of the menstrual cycle. If we suspend the command from time to time, the end result will be that the good cycle of ovulation will become irregular or non-ovulatory, leading to long-term menstrual disorders and eventually to a decrease in fertility. Since emergency contraceptives are mostly taken by women who have not had children, there is no situation more frightening than not being able to have children. Experts in all areas have called for the emergency contraceptive pill to be used as a remedy for contraceptive failure and not as a regular method of contraception. Some experts even state that the emergency contraceptive pill should be used no more than 2 times a year. If you really need emergency contraception more than 3 times in a year, then whether or not it causes physical effects, it means that the woman does not cherish herself, and the woman’s male partner does not cherish her. A woman who doesn’t even love herself, how can she be loved?
