Non-hormonal birth control is any contraceptive method that prevents pregnancy without using hormones. Examples include the copper IUD, condoms, the diaphragm, fertility awareness methods and sterilization.
Non-hormonal methods fall into a few main groups.
Effectiveness varies widely between methods. The copper IUD and sterilization are more than 99% effective. Condoms and diaphragms work well when used correctly every time, but they are less reliable in typical use. Fertility awareness methods need careful daily tracking and good teaching to work well. Only condoms also protect against sexually transmitted infections.
People choose hormone-free contraception for many reasons. Some have side effects from hormonal methods, such as mood changes or headaches, and some have health conditions that make hormones unsuitable. Others prefer to keep their natural cycle or want a method they control themselves.
A GP, nurse or sexual health clinic can explain the options and help find a method that fits your health, lifestyle and plans for pregnancy. The copper IUD can make periods heavier or more painful for some people, which is worth discussing before choosing it.
