How often should a diaphragm be replaced?

A diaphragm should typically be replaced every two years. This timeline is important because over time, diaphragms can lose their shape, flexibility, and effectiveness due to material degradation or wear-and-tear. Using a diaphragm that is past its recommended lifespan may increase the risk of unintended pregnancy, as it may not provide adequate contraceptive protection.

It is also important to note that while diaphragms need to be cared for and cleaned after each use, this does not mean they are intended to be replaced after each use. They are designed for multi-use over an extended period, which reinforces the necessity of replacing them every two years to maintain their effectiveness and safety. Replacing the diaphragm after every pregnancy is also not sufficient if the diaphragm is still within its effective lifespan.
