Diaphragms represent a leading alternative barrier method of contraception for women put off using condoms during intercourse. The diaphragm is a dome shaped device measuring anywhere from five to ten centimetres in diameter. It is most commonly made from a thin, soft rubber or silicone which gives it a flexible quality that allows users’ to bend it during the fitting process. The diaphragm is placed high inside up inside the vagina, before any sexual activity begins. It should cover over the cervix to prevent sperm from getting into this region and leading to unplanned pregnancy. The diaphragm should be used in conjunction with spermicidal cream or gel as this helps to prevent the escape of any rogue sperm from reaching the cervix.
