Worrying about whether contraception might affect your ability to have children one day is one of the most common concerns raised in reproductive health consultations. It is completely understandable to think about your long-term fertility when making decisions about birth control, especially if you plan to start or grow a family in the future.
The reassuring reality is that reversible contraception is designed to be temporary. Once you stop using it or have it removed, your body begins returning to its natural cycle. The timeline for this varies depending on the method. To explore the full range of options available to you, visit our contraception services page.
How Long Does It Take for Fertility to Return?
The answer depends on which contraceptive method you have been using. Here is what to expect for each:
IUD (Copper and Hormonal)
Both the copper and hormonal IUD are forms of long-acting reversible contraception. Your cycle and fertility return quickly once an IUD is removed. The copper IUD contains no hormones, so there is no hormonal adjustment period at all after removal. You can read more about the differences between the two on our IUD information page.
Contraceptive Implant (Rod)
The contraceptive implant is a small rod inserted under the skin of the upper arm that releases progestogen over three years. Once the implant is removed, fertility returns quickly, with periods typically returning within one month of removal. Learn more about the contraceptive rod on our LARC page.
The Contraceptive Pill
The pill works by preventing ovulation. Once you stop taking it, your body begins returning to its natural hormonal cycle and fertility can return quickly. In fact, even missing a single pill can sometimes allow an egg to be released, which is why there is still a risk of pregnancy if pills are missed. There may be a short delay in the return of your normal cycle for some people, but this is usually temporary.
The Contraceptive Injection
The contraceptive injection is the one method where a longer delay is common. Because the hormone is released slowly into the body over 12 weeks, it takes more time to clear after stopping. Periods may take an average of eight months to return to normal, and it can take up to 18 months for fertility to normalise. This delay is temporary, not permanent. However, if you are planning to conceive within the next 12 to 18 months, it is worth speaking with one of our clinicians about switching to a different method.

The “Masking” Effect: Why Do Some People Blame Birth Control?
Hormonal contraception methods, including the pill, implant, and hormonal IUD, regulate or suppress the menstrual cycle while in use. This can sometimes mask the symptoms of underlying conditions that may have already been present before starting contraception. Common conditions that may go undetected while on hormonal contraception include:
- Polycystic Ovary Syndrome (PCOS): PCOS causes irregular or absent periods and is one of the most common causes of infertility in females. Because the pill can improve PCOS symptoms, the condition is often not diagnosed while hormonal contraception is in use.
- Endometriosis: Hormonal contraception is commonly used to help manage endometriosis symptoms, which can mean the condition goes undiagnosed until contraception is stopped.
- Naturally irregular cycles: These may not become apparent until contraception is stopped.
What Actually Affects Fertility?
Understanding what does and does not affect long-term fertility can help you make more informed decisions. Factors that may cause infertility include:
- Age: Fertility naturally declines with age for both females and males, particularly after the age of 35 for females.
- Untreated sexually transmissible infections (STIs): STIs can cause damaged or blocked fallopian tubes.
- Underlying reproductive conditions: PCOS, endometriosis, and uterine fibroids can contribute to female infertility.
- Male factor: Around one in three infertility cases involves a male factor, including low sperm count, poor sperm movement, or hormonal issues.
If you have concerns about any of these factors, speaking with a healthcare professional is the most important first step.
