The FemCap is a similar concept to the traditional diaphragm, and works by covering the cervix, preventing sperm from entering. Unlike traditional diaphragms and caps, the FemCap does not need fitting by a health professional - it is available in three simple sizes, and the one you need is simply based on your pregnancy history. Small (22mm): is designed for women who have never been pregnant. Medium (26mm): for women who have been pregnant (even if only for two weeks) and have miscarried, undergone termination, or given birth by caesarian section - this size should be used if there is doubt over whether you have ever been pregnant. Large (30mm): for all women who have given birth vaginally. The FemCap is a hormone-free method of birth control that can remain in place for up to 48 hours at a time, and is fully reusable for up to a year. After each use, simply wash your FemCap with a gentle antibacterial hand soap and store in its case. The FemCap should be used in conjunction with a contraceptive gel to ensure proper protection against pregnancy. The FemCap is a modern, easy-to-use alternative to the traditional diaphragm. It is made of a single piece of medical-grade silicone to reduce allergies and can be left in place for up to 48 hours. As your body moves and changes during intercourse, the soft silicone design conforms to your body, and removal is easy too with the built-in removal strap - unlike the diaphragm, the soft silicone FemCap won't cause abrasions when the time comes to remove it. The FemCap is shaped like a sailor's hat, with a brim to prevent sperm from entering the cervix. FemCap has been proven to be over 92% effective in preventing pregnancy, when used in conjunction with a spermicide. The FemCap is also ideal if you think you may want to get pregnant in the near future, because unlike the Pill or the implant, the effects are instantly reversible simply by removing the FemCap.
