10 Best Methods of Birth Control

3. Copper IUD

Yes, IUDs have already made an appearance on this list—but this one is a bit different. The copper IUD also sits inside the uterus, and it stays put for up to ten years. The major difference is that the copper version contains zero hormones. The copper itself impedes pregnancy by making the uterus unfavorable to sperm. Basically, it creates an unpleasant, hostile environment that sperm want to stay away from. Some women prefer the copper IUD because it’s hormone-free. Again, this method is a longer-term solution.
