Can Birth Control Pills Cause Infertility in the Future? Facts vs Myths

Infertility is a serious problem that is faced by a large number of couples all over the world. In fact, about 40 %- 50 % of these cases are due to female infertility. But the good news is that a woman's ability to get pregnant in the future does not depend on whether she takes birth control pills at present or not.

Infertility Due to Birth Control Pills - Myth or Reality

To put it in straight and simple words, infertility due to birth control pills is a myth. There is no scientific basis to believe that if you are on birth control pills for a long time, you won't be able to get pregnant once you stop taking the pills. In fact, several studies have indicated that you are likely to get pregnant if you have been on birth control pills in the past as much as a woman who has never taken a contraceptive pill in her life.  
Birth control pills basically comprise of hormones that ensure your eggs do not ovulate. These hormones also play a role in thickening your cervical mucus, which helps to prevent the sperm from reaching your eggs.  
Once you discontinue taking your contraceptive pills, the hormone supplements should leave your body in a couple of days or at most a couple of weeks. When these hormones are out of the body, your menstrual cycle starts functioning in a normal manner and your fertility returns to its usual state. In some cases, ovulation can kick in even before the hormones are fully out of a woman's system.  
If you are unable to get pregnant after discontinuing the birth control pills, it does not mean that the pills are responsible for this development. You need to consult your medical practitioner to determine the exact cause of your inability to conceive.

What are Birth Control Pills?

Birth control pills refer to a common type of oral contraception used to prevent pregnancy. Most women simply call it “the pill.” It contains hormones that basically tell the body not to follow its usual monthly fertility routine. The biggest job of these hormones is to stop ovulation. In simple words, the ovary does not release an egg. And if there is no egg, pregnancy cannot happen.

Birth control pills also affect the cervix by making cervical mucus thicker. This matters because sperm usually need to travel through this mucus to reach the uterus. When mucus thickens, it becomes harder for sperm to move forward. Some pills may also thin the lining of the uterus, which makes it less supportive for implantation.

A lot of women get anxious and start thinking about contraceptive pills and infertility, especially if they have taken the pill for years. But medically speaking, there is no strong evidence that the pill permanently damages fertility. In most cases, hormonal pills restore fertility once the pills are stopped. For many women, the cycle becomes normal within weeks or a few months. That is why doctors commonly say fertility after birth control is usually the same as that of someone who never used it.

So when people talk about long-term pill effects on fertility, they’re usually talking about the body taking some time to settle back into its normal cycle, not permanent infertility.

What are the Types of Birth Control Pills?

There are two clinically recognised types of birth control pills. The classification is based on the tablet's hormonal composition.

• Combination Pills (Estrogen + Progestin):

  These contain two hormones, estrogen and progestin. They stop the release of an egg during the cycle, which is why pregnancy becomes unlikely.

• Progestin-Only Pills (Minipill):

  These contain only progestin. They are often used when estrogen is not advised, such as during breastfeeding.

Some women may notice birth control pills side effects when starting, including nausea, headaches, breast tenderness, mood changes, or spotting. These effects often settle as the body adjusts.
