Little Cherry,

I have been sexually active for a few years and am interested in taking birth control. (Don’t worry, I already get tested for STDs!) I did some research online about cervical caps and diaphragms, but I still can’t tell them apart. Can you please tell me what the difference is and why people use them.

Dear Confused,

Great questions! In a lot of ways, diaphragms and cervical caps are very similar. Both are prescription forms of birth control, which function as barrier methods- meaning that they block the sperm from entering into the uterus, thus preventing pregnancy. (They do so by covering the cervix.) They also require the use of spermicide, which helps to kill off the sperm. If taken care of properly, cervical caps and diaphragms can both last for a couple of years. Nevertheless, there are a few key differences.

Differences between cervical caps and diaphragms include:

· Cervical caps come in only a few set sizes, which unfortunately do not cater to all women’s shapes. Diaphragms, on the other hand, are specifically fit to each body by a doctor.

· The diaphragm covers not only the cervix, but also some of the area around the cervix. By covering more surface area, it may help to protect against some STDs. (*Even so, you still need to use a latex condom with either one of these methods in order to prevent STD transmission!)

· Cervical caps and diaphragms must be kept in prior to and post sex for different amounts of time. Ask your doctor for more specific details.

When picking out your birth control, I’ve got a bit of advice to keep in mind: birth control is not only a product, but also a method. I stress this because if it doesn’t fit into your lifestyle, it’s very easy to take the product incorrectly (resulting in a drop in the effectiveness rate.) As I’ve already mentioned, both forms of birth control require you to prepare for sex ahead of time. Do you need something spur of the moment? Would this be too much of a hassle? Also, are you comfortable feeling around for your cervix and inserting the birth control? This is certainly not to discourage you from using the diaphragm or cervical cap. They can both be really great options, especially for those unable to use hormonal methods. Since you are interested in learning more, I would definitely recommend speaking to your health care provider about any birth control questions or concerns. Also, check out our episode entitled ‘Barrier Birth Control’ for more advice. Hopefully, you’ll find a method that’s a ‘great fit.’

Ask questions!,
