What is the oral contraceptive method?

Contraception is a common topic in couples' lives. If contraceptive measures are not taken in time, it will bring a lot of unnecessary troubles, especially for couples who do not want to have children again. Failure to take contraceptive measures in time will lead to unwanted pregnancy, and unwanted pregnancy can only be treated by abortion, which has a great impact on women's bodies. Therefore, taking birth control pills is a better way of contraception. Here I will introduce you to the method of oral contraceptives.

Oral contraceptives are the most common contraceptive method. They are made of artificially synthesized estrogen and progesterone and have a very high contraceptive success rate. After years of research and improvement, the side effects of oral contraceptives are now very mild, and there may only be early pregnancy reactions at the beginning. Moreover, if birth control pills are taken regularly and long-term, they can help "calibrate" the menstrual cycle. On May 31, 1961, the oral contraceptive pill was approved for use in the United States.

The basic types of oral contraceptives are divided into three categories: short-acting, long-acting, and rapid-acting.

The mechanism of action of short-acting oral contraceptives is to inhibit ovulation. There are oral contraceptive tablets No. 1, oral contraceptive tablets No. 2 and compound 18A contraceptive pills.

Dosage: Start taking the medicine on the 5th day from the day of menstruation, and continue for 22 consecutive days without any interruption. It can be used for contraception for 1 month. Generally, stop taking the medicine 1-3 days after menstruation, and continue taking it from the 5th day of the next menstruation. The method is the same as above.

Why do we have to start taking the pill from the 5th day of menstruation and not miss a dose? Because the main function of contraceptives is to inhibit ovulation. If you take the pill after the 6th day, the egg cells will develop to a certain extent and the inhibitory effect will not be achieved, thus creating the possibility of pregnancy. If you miss a dose in the middle, vaginal bleeding is likely to occur, disrupting the normal menstrual cycle.

The mechanism of action of long-acting oral contraceptives is to inhibit and change the speed of the fertilized egg. Taking one pill per month can provide contraception for one month and is suitable for couples living together for a long time.

Dosage: Take one tablet on the 5th day of menstruation, 2 tablets on the 25th day, and then take one tablet on the same day of the second dose every month.

Rapid-acting oral contraceptives are also known as visiting contraceptives. Its mechanism of action is mainly to quickly inhibit ovulation, affect sperm penetration and prevent the fertilized egg from implanting. The advantage is that it is not restricted by the menstrual cycle and can be taken whenever you visit relatives.

From the above introduction, it can be seen that different contraceptives have different methods of taking. It should be noted that rapid-acting contraceptives should not be used frequently, generally not more than 3 times a year. If the number of times is too many, it will cause great harm to the female body, and may cause infertility in severe cases. Of course, there are many ways of contraception, and other methods can also be taken.
