Nexplanon, a long-acting reversible contraceptive (LARC), is a discreet and effective method for preventing pregnancy. This small, flexible rod, approximately the size of a matchstick, is inserted under the skin on the inner side of the upper arm. Designed to provide continuous pregnancy protection for up to three years, Nexplanon eliminates the need for daily or weekly attention.
How Nexplanon Works
Nexplanon prevents pregnancy by continuously releasing a low dose of etonogestrel, a synthetic progestin hormone. This hormone acts through several mechanisms to inhibit conception. Primarily, etonogestrel prevents ovulation, stopping the ovaries from releasing an egg each month. This is achieved by suppressing the mid-cycle luteinizing hormone (LH) peak, which is necessary for ovulation.
Etonogestrel also alters the cervical mucus, causing it to thicken significantly. This thickened mucus creates a barrier, making it difficult for sperm to travel through the cervix and reach an egg. Additionally, the hormone thins the lining of the uterus, making it less receptive for a fertilized egg to implant.
Fertility’s Return After Removal
A notable characteristic of Nexplanon is the rapid return of fertility following its removal. For many individuals, the ability to conceive can resume quickly, often within weeks or even days. Studies indicate that ovulation typically resumes within three to four weeks for most women after the implant’s removal. This quick return to fertility makes Nexplanon a suitable option for those planning future pregnancies.
While a rapid return is common, the exact timing can vary among individuals. Factors such as pre-existing irregular menstrual cycles or other underlying health conditions may influence how soon fertility is restored. Signs that fertility is returning often include the resumption of menstrual periods, which for most people occurs within three months of removal. It is possible to become pregnant even before the first period after removal, as ovulation can precede menstruation.
Preparing for Pregnancy
For individuals who have had Nexplanon removed and are now aiming to conceive, several practical steps can support the process. Tracking menstrual cycles, once they resume, is beneficial for identifying the fertile window. This can involve observing changes in cervical mucus or using ovulation predictor kits. Understanding the body’s natural rhythms can help in timing intercourse for conception.
Adopting general pre-conception health practices is also recommended. This includes taking a daily folic acid supplement to support fetal development and reduce the risk of certain birth defects. Maintaining a balanced diet, engaging in regular physical activity, and avoiding alcohol and smoking are additional measures that contribute to overall reproductive health. If a period is missed, taking a pregnancy test can confirm conception. Should conception not occur within a typical timeframe, such as after 6 to 12 months of consistent trying, consulting a healthcare provider for further guidance is advisable.
