How long should a diaphragm remain in place after intercourse for it to be effective?

The diaphragm is a barrier method of contraception that needs to remain in place for a specific duration after intercourse to ensure its effectiveness in preventing pregnancy. It works by covering the cervix to block sperm from entering the uterus. For optimal efficacy, the diaphragm should be left in place for at least 6 hours after sexual intercourse. This duration allows sufficient time for the sperm to be neutralized and helps to further decrease the likelihood of fertilization.

Many options suggest shorter or longer durations, but the key factor here is that a 6-hour interval strikes a balance between allowing enough time for the contraception to be effective while also ensuring comfort for the individual. Leaving it in place for fewer than 6 hours may not give the barrier enough time to effectively prevent sperm from reaching the egg.
