Intrauterine devices (IUDs) are a widely used and highly effective form of birth control. Many individuals decide to have their IUD removed when ready to start or expand their families. A common question is how quickly fertility returns after IUD removal and the timeline for conception. Understanding this process can help individuals plan their family-building journey.
Immediate Return of Fertility
Fertility can return rapidly after IUD removal. It is possible to become pregnant as soon as the first menstrual cycle after removal, and some even conceive within the same month. IUDs, whether hormonal or copper, primarily have localized effects, not systemic changes that impact long-term reproductive hormone levels or uterine health.
Hormonal IUDs, such as Mirena, Kyleena, Liletta, and Skyla, release a synthetic progestin hormone that thickens cervical mucus, thins the uterine lining, and can sometimes suppress ovulation. Once removed, the hormone quickly exits the body, allowing ovulation to resume within days or weeks. While some individuals might experience a temporary shift in their menstrual cycle as their body readjusts, cycles normalize within about a month.
Copper IUDs, like Paragard, do not use hormones. Instead, they create an inflammatory reaction in the uterus that is toxic to sperm, preventing fertilization. Since copper IUDs do not affect ovulation, fertility can return immediately upon removal. Neither hormonal nor copper IUDs have been shown to cause long-term impairment of fertility once removed.
Factors Influencing Conception Time
Several factors can influence how long it takes to conceive after IUD removal. A person’s age is a significant determinant, as female fertility naturally declines with increasing age, particularly after the mid-30s due to a decrease in both the number and quality of eggs. The chance of conception per cycle is considerably lower for women in their 40s compared to those in their 20s.
Overall health and lifestyle choices also influence conception time. Factors such as diet, exercise habits, body weight, smoking, and alcohol consumption can affect fertility. For instance, both being overweight or underweight can impact hormone balance and ovulation regularity. Pre-existing medical conditions, such as Polycystic Ovary Syndrome (PCOS) or endometriosis, can also make conception more challenging, regardless of prior IUD use.
A person’s fertility history before IUD insertion can provide insight into potential conception difficulties. If irregular menstrual cycles were present before IUD use, these irregularities may return after removal, which can complicate efforts to track ovulation and time intercourse for conception. Some individuals may discover underlying fertility issues after stopping contraception, not because the IUD caused them, but because the IUD masked existing conditions.
When to Consult a Healthcare Provider
Knowing when to seek medical advice for conception can help manage expectations. For individuals under 35 years old, it is recommended to consult a healthcare provider if pregnancy has not occurred after one year of regular, unprotected intercourse. This timeframe allows for a reasonable period of trying to conceive naturally.
Individuals who are 35 years or older should consider seeking a fertility evaluation sooner, after six months of trying to get pregnant without success. This earlier consultation is advised because fertility naturally declines more rapidly after this age. Furthermore, if known underlying health conditions like very irregular menstrual cycles, a history of endometriosis, or previous pelvic infections could affect fertility, it is advisable to consult a healthcare provider earlier than these guidelines.
