Why does a diaphragm stop working?

A diaphragm can stop working due to several reasons, including mechanical failure, loss of tension, or damage to the diaphragm material. In medical contexts, a diaphragm may also fail due to hormonal changes, anatomical shifts, or improper placement. Regular wear and tear or lack of maintenance can lead to decreased effectiveness over time. In any case, it's essential to identify the cause to ensure proper function and safety.
