How does an iud work

Intrauterine devices (IUDs) are one of the most effective and low-maintenance forms of birth control available, with a failure rate of less than 1% per year.

They prevent pregnancy by either releasing hormones that prevent ovulation (hormonal IUD) or creating an environment that's hostile to sperm (copper IUD).

For some users, the benefits of IUDs may go beyond birth control.

Hormonal IUDs can help reduce common menstrual problems like heavy menstrual bleeding and cramps.

They may also offer relief for other conditions, like endometriosis and polycystic ovary syndrome (PCOS).

IUDs and Pregnancy 

IUDs are over 99% effective at preventing pregnancy. The low failure rates make IUDs a popular choice among those seeking long-acting reversible contraception (LARC).

In the United States, 14% of all contraceptive users between 15 and 44 years old have an IUD.

Once a healthcare provider inserts the T-shaped device into the uterus, it works continuously for three to 10 years, depending on the type.
