A Full Circle Look at Diaphragms

Diaphragms have been around for quite some time and while they’ve become less popular as other and more convenient methods of birth control have been invented over the years, they still remain a good option for a woman looking for a reliable contraceptive.

How They Work

Diaphragms are latex or silicone domes with a small spring contained within the rim that helps to keep it in place. It is inserted into the vagina before sex and works by creating a barrier between the cervix and a man’s penis. Spermicide is to be poured into the diaphragm before insertion for the best results. You can also add more spermicidal lubricant or foam after insertion for even more protection. One other thing you need to know about diaphragms is that they need to remain inside the body for anywhere from six to eight hours after a man ejaculates.

For a diaphragm to work best it needs to fit properly so that it covers the entire cervix. A fitting with your doctor is necessary to ensure the best possible fit. A diaphragm that is too small won’t provide you with enough protection against unwanted pregnancy and can result in some discomfort for you and your partner during sex. And if you’re diaphragm is too big you run the risk of pain along the vaginal wall as well as urinary tract infections because of the pressure and possible damage caused to your urethra by the diaphragm.

Diaphragms can be used for up to 3 years before they need to be replaced, though it is advised that they should be re-fitted after significant weight loss or pregnancy.

The Downside

Diaphragms require a prescription in the US as well as some other countries which can sometimes be a deterrent for some women. Also, having to go for a fitting is often the reason why women opt out of using a diaphragm. Other methods of birth control with the same or greater success rate don’t require a fitting which makes them a more attractive option. Speaking of success rate, they are 94 percent effective against pregnancy when used perfectly. That percentage is significantly lower in terms of typical use.

While they are fairly reliable against pregnancy, diaphragms do not protect you from sexually transmitted diseases unless you pair them with condoms. There has been some evidence to show that they lower your chances of some STDs because of their barrier-type action, but they are not nearly as effective as condoms and they DO NOT protect you against HIV/AIDS.
