Not everyone wants to expect a child in their life, maybe not for certain times. We live in the modern age; people are busy with their studies, carrier, and passion. Some people may view the idea of having a child or taking on the responsibilities of parenthood as troublesome.

Either someone already has more than two children they don’t want more. Let me share an interesting story about the birth control system in China. Do you know previously, China had a policy known as the “one-child policy?

China's One-Child Policy initially limited most couples to one child to manage population growth,” which was implemented from 1979 to 2015. No worries, the policy has been changed. In general, birth control may take to 24 hours to 7 days to work.

Before you know how long does it take birth control to work, you should know what types of birth control are going to be better for your needs. I’m about to share with you some crucial aspects of how does birth control works alongside the help of a medical expert Joshua Collins (MD, MRCP, FRCP).

What is Birth Control?

The term "birth control," also known as contraception, several methods and devices used to prevent pregnancies that are not intended. It involves different techniques and medications that are designed to hinder or regulate the reproductive process.

The primary purpose of birth control is to prevent pregnancy and the fertilization of an egg by sperm, thereby preventing pregnancy from occurring. You will find different types of birth control systems or methods for men and women.

Birth control is a way of preventing pregnancy. Lots of different types of birth control are found in the modern age, and each one works in a different way. Let's take a look at some of the most common methods of birth control.

Hormonal birth control

This method involves the use of hormones to inhibit ovulation. By using hormones, this approach prevents ovulation, the ovaries' discharge of an egg, and also thickens cervical mucus, creating a barrier that impedes sperm from reaching the uterus. Such as hormonal birth control include birth control tablets, rings, shots, patches, and implants.

Barrier methods

Diaphragms, condoms, and cervical caps are examples of barrier methods, which operate by creating a physical barrier that obstructs the sperm's path to the egg as a means of birth control.

Intrauterine devices (IUDs)

A medical professional inserts these little T-shaped devices inside the uterus. IUDs can be both hormonal and non-hormonal (copper), and they work in various ways to prevent pregnancy.


It is a surgical procedure for a man. This procedure permanently prevents a man from ejaculating sperm. Among the most highly effective types of birth control for men.

Tubal ligation

By obstructing the fallopian tubes that transport eggs from the ovaries to uterus, eggs cannot reach the uterus. Tubal ligation is a permanent way for women to prevent pregnancy.

How Long Does It Take for Different Types of Birth Control to Work?

The effectiveness of various types of birth control can vary and depends on each method used, price, time, etc. Here's a general overview of the timeframes for various birth control methods to work:

  1. Birth control pills: These pills (estrogen and progestin) usually take about 7 days to become fully effective if started at the beginning of the menstrual cycle. Progestin-only pills (mini-pills) might take up to 48 to 72 hours to become effective.
  2. Condoms: Condoms are immediately effective once worn correctly. However, it's essential to use them consistently and correctly for maximum effectiveness. And another vital fact is condoms not only can stop pregnancy but also reduce the risk of STDs.
  3. Intrauterine devices (IUD planned parenthood):
  • Copper IUD: A copper IUD is instantly effective after implantation.
  • Hormonal IUD: A hormonal IUD is usually effective within 7 days if inserted within 7 days of the start of the menstrual cycle. And it could be last around 2-6 years.
  1. Implants: Implants, such as the contraceptive implant (e.g., Nexplanon), are usually effective within 24 hours of insertion.
  2. Sterilization (vasectomy or tubal ligation): Sterilization procedures are considered effective immediately after the procedure. However, it's advisable to use another form of birth control until confirmed by a healthcare professional.
