What is a key requirement for the proper use of a diaphragm as contraception?

The requirement for a diaphragm to be properly fitted by a doctor is essential for its effectiveness as a contraceptive method. A personalized fit ensures that the diaphragm covers the cervix completely and forms a seal to prevent sperm from entering the uterus. If the diaphragm is too large, it may shift during intercourse, losing its effectiveness. Conversely, if it’s too small, it may not provide adequate coverage. A healthcare professional will take appropriate measurements and provide guidance on the correct type and size, contributing to increased efficacy and user confidence.

Proper fitting and guidance also include instructions on how to use and care for the diaphragm, which is critical for its longevity and effectiveness, supporting both proper placement and removal. Maintaining the correct fit helps minimize the risk of unintended pregnancies and ensures that users can rely on this method of contraception effectively.
