“To each her own.” That about sums up the process of choosing the right birth control method — it truly comes down to a matter of personal preferences, and what works for one person might not for another. But an increasing number of women are seeking out — or at least considering IUDs — and with good reason. These tiny devices are effective, affordable, and also maintenance-free. And a quick glance at the many tweets about getting an IUD will show that there are a plethora of perks to this birth control method, as well as potential pitfalls, of course.

True to its name, the intrauterine device (IUD) is implanted into the uterus, where it emits either copper or the hormone progestin to prevent sperm from reaching the egg and fertilizing it. And this tiny T-shaped rod is one of the most effective birth control methods available. In fact, it’s more than 99 percent effective. So it makes sense that according to AthenaHealth, the number of women who visited their doctor to discuss getting an IUD increased by nearly 19 percent since the fall of 2016. One of the reasons why the IUD is so effective is that there’s no risk of making a mistake, like forgetting to take a pill, or using it incorrectly, like putting a condom on the wrong way. Basically, you can pretty much forget about it and let it do its thing after getting it implanted. It starts working right away, and to boot, it lasts for years (or until you decide to get it removed).
