How does birth control work?

Birth control is used to prevent unwanted pregnancy. For that, there are various methods, such as the use of birth control pills, vasectomy, vaginal rings, use of patches, use of condoms, etc. However, birth control works only when it is used correctly. These birth control methods not only prevent unwanted pregnancy but also protect you against sexually transmitted infections. Moreover, you should keep in mind that no form of birth control is one hundred percent effective, and the birth control method that is most convenient and easy to maintain is usually preferred by doctors like Dr. Nicole DeQuattro Silver Spring

Working on birth control methods

In order to understand how these birth control methods work, you first need to understand how children are born. For conception to occur, the sperm released by the male has to meet the egg released from the ovary of the female. When they combine, the formation is called a zygote. The zygote, after a certain period, forms an embryo. Embryo takes the shape of a baby after a proper course of time. 

Now, as far as birth control methods are concerned, each of these methods works differently. However, generally, they aim at preventing the sperm from reaching the egg, preventing the ovary from releasing an egg, damaging the sperm before it meets an egg, etc. 

Below mentioned are some of the common birth control methods and the way they work:

  • Hormonal methods: Certain pills, like birth control pills, prevent ovulation by changing the condition of your uterus and cervix.
  • Barrier methods: Use of condoms, diaphragm, cervical cap, etc., physically block the meeting of the sperm and the egg. 
  • Intrauterine Devices (IUDs): There are two types- hormonal IUD, which thickens the cervix and restricts the movement of sperm and Copper IUD, which creates a toxic environment for the sperm. 
  • Emergency pills: These emergency contraceptives are used as a last safety measure to avoid pregnancy. They do not protect you against pregnancy that has already taken place. They work either by delaying your ovulation, where your ovary temporarily stops releasing an egg. It works best when taken within 24 hours after unprotected sex. 

However, it is very important to keep in mind that none of the above-mentioned birth control methods are 100% effective, and you must not rely on them blindly. They need to be used correctly and on time. Moreover, you must consult your healthcare provider to get your queries resolved before using a particular birth control method.
