Can birth control\u00a0harm your fertility? Many hormonal contraceptive choices have risks, but infertility is not one of them. According to numerous studies, you are as likely to conceive if you used birth control in the past as a woman who has never used hormonal contraceptives.<\/p>\n

In fact, one of the largest studies looked at women who had been using birth control for seven years. They found that 21.1 percent conceived in their first fertile month. Of those who didn\u2019t conceive right away, 79.4 percent were pregnant within a year. This is similar to the\u00a0general population\u2019s odds for conception.\u00a0<\/p>\n

[Note that the study specifically refers to the woman’s first fertile month after stopping contraception. There can be some slight\u00a0wait time between when you stop birth control and your fertility returns. With the exception of the\u00a0birth control shot, this waiting period is usually short.<\/p>\n

With all that said, there are some small studies that raise concerns about the long-term risks to birth control. However, as you will see below, these studies should be taken with a grain of salt.<\/p>\n

Long Term Contraceptive Use and Endometrial Lining<\/strong><\/h2>\n

A study published in\u00a0Obstetrics and Gynecology<\/em>\u00a0reported that women who used combined (estrogen and progestin) birth control pills for five or more years were significantly more likely to have thinner endometrial linings.\u00a0The endometrium\u00a0lines the uterus and is where an embryo would implant itself during pregnancy.<\/p>\n

However, in this study, the 137 patients were already being seen in a\u00a0fertility clinic. (The study was done on women preparing for a\u00a0frozen embryo transfer.) These women were already getting\u00a0IVF treatment\u00a0and the results may not apply to women with otherwise healthy fertility.<\/p>\n

Also, while the researchers concluded that long-term oral birth control pills may increase the risk of IVF cycle cancellation (due to the thin lining), pregnancy rates appeared to be similar between the groups.<\/p>\n

In other words, as long as you were able to complete your IVF cycle, your odds of getting pregnant would be the same as someone who had never used the combined birth control pills.<\/p>\n

Birth Control and Menstrual Cycle Variations<\/strong><\/h2>\n

In another interesting but small study published in\u00a0Gynecological Endocrinology<\/em>, a group of 175 women who discontinued oral contraceptives was compared to a group of 284 women who had never taken birth control pills.<\/p>\n

The women charted their\u00a0body basal temperatures. This allowed researchers to observe cycle length,\u00a0ovulation, and\u00a0luteal phase length. The luteal phase is the time between ovulation and your expected period.\u00a0<\/p>\n

The study found that 57.9 percent\u00a0of the women who discontinued birth control pills ovulated and had healthy luteal phases in their first post-pill cycle.<\/p>\n

However, many women in the post-pill cycle group had longer menstrual cycles than non-pill users. This lasted for up to 9 months. Also, more women in the post-pill group had shorter than normal luteal phases. These cycle disturbances eventually corrected themselves by 9 months post-birth control use.<\/p>\n

With that said, it\u2019s important to note that this study did not look at\u00a0clinical pregnancy rates\u00a0and whether these\u00a0cycle irregularities\u00a0were enough to impact fertility.<\/p>\n

Also, some women go on birth control to help regulate their irregular cycles. We don\u2019t know how many of the women taking the birth control\u00a0had irregular cycles\u00a0before starting. Having irregular cycles may have increased their risk of longer-term effects.<\/p>\n

Post-Pill Amenorrhea: Not Ovulating After Birth Control<\/strong><\/h2>\n

You should have a cycle within one to three months of discontinuing most forms of reversible birth control. If you stopped birth control and haven’t gotten a period yet, you may want to\u00a0take a pregnancy test\u00a0first. It\u2019s possible you conceived! You can get pregnant the very next month after stopping birth control.<\/p>\n

If you\u2019re not pregnant, you may be experiencing post-pill amenorrhea. This is when you don\u2019t get a period for up to 6 months after discontinuing birth control pills. Despite its name, this\u00a0lack of ovulation\u00a0is probably not due to birth control use.<\/p>\n

Birth control creates a \u201cfake\u201d menstrual cycle. Even if a woman has a fertility problem that would\u00a0cause anovulation, the hormones in the birth control pills would trigger a period. It would look like she has regular menstrual cycles.<\/p>\n

But this only applies as long as she is taking them. If you had irregular periods before starting birth control, you will likely have them again after you stop. There\u2019s a misconception that birth control pills \u201ccure\u201d irregular cycles. They don\u2019t. They create an artificial cycle, but they don\u2019t solve the original cause for the irregular cycles.<\/p>\n

Be sure to see your doctor if you\u2019re not ovulating after birth control pills or if your cycles are irregular or absent. Your doctor will likely run\u00a0some fertility tests.<\/p>\n


Your doctor may\u00a0prescribe Clomid\u00a0to \u201cjump start\u201d your fertility.<\/p>\n

Fertility and the Birth Control Shot<\/strong><\/p>\n

Above, we mentioned that your cycles should return within about three months of stopping birth control, if not sooner. One major exception to the one-to-three-month rule is if you had the birth control shot.<\/p>\n

If you had a Depo-Provera (or DMPA) shot, you\u00a0should get a cycle after 6 to 12 months of your last injection.<\/p>\n

However, some women experience disruptions to their fertility for up to 18 months. Don’t panic if you don’t get your fertility back right away after Depo-Provera. It can take up to 22 months\u2014or almost two years\u2014for your cycles to return after the birth control shot. That’s not the average, but it’s possible.\u00a0<\/p>\n

(This is why your doctor was supposed to confirm that you had no family building plans in the near future, before prescribing the shot.)<\/p>\n

If you don\u2019t get a period within 22 months, talk to your doctor.<\/p>\n

What If You Can\u2019t Get Pregnant After Birth Control Pills?<\/strong><\/h2>\n

You stopped birth control pills, your cycles have returned, but you\u2019re not getting pregnant. Now what? While you may wonder if your birth control pills caused your problems, rest assured that this is highly unlikely.<\/p>\n

There are many reasons why you may struggle to conceive. Infertility affects 12 percent\u00a0of couples, and both men and women can experience fertility problems. In cases of female infertility,\u00a0not ovulating\u00a0is only one possible cause.<\/p>\n

If you don\u2019t conceive after six months (if you\u2019re over 35), or you don\u2019t conceive after a year, see your doctor.<\/p>\n


Don\u2019t wait! Delaying testing and treatment may reduce your odds for pregnancy success.<\/p>\n

Preventing Pregnancy Without Hormonal Birth Control<\/strong><\/h2>\n

Even though the majority of research shows hormonal birth control doesn’t cause infertility, some women still want to avoid it. Does this mean they have no way to prevent pregnancy? Of course not!<\/p>\n

You may want to consider\u00a0barrier method options. This includes contraception like condoms or a diaphragm. Barrier methods of birth control do require you to use them. They can’t be effective if you forget or don’t place them properly.<\/p>\n

However, for those that are consistent and careful, they can provide an effective way to avoid pregnancy, while not interfering with your hormones.<\/p>\n
