Diaphragm, Sponges, and Cervical Caps: What You Need to Know

Diaphragms, sponges, and cervical caps are three methods of birth control that are designed to be used by women. While each method works in its own way, they all offer a non-hormonal alternative to common forms of birth control like the pill or IUD.

Diaphragms

A diaphragm is a small, dome-shaped device made of silicone that sits inside the vagina. It works by blocking the cervix so sperm cannot enter the uterus and fertilize an egg. Diaphragms need to be fitted by a healthcare professional and come in different sizes to ensure a proper fit.

One advantage of using a diaphragm is that it can be used only when needed, making it a more flexible form of birth control. However, it does require planning ahead and inserting it 6-8 hours before intercourse, and then needing to leave it in the vagina for at least six hours afterward to ensure efficacy. Diaphragms should also be used with a spermicide, which is a chemical that kills sperm and helps to increase their effectiveness in preventing pregnancy. Finally, diaphragms need to be replaced every one to two years or if the person using it has a change in weight or a delivery of a baby.

Sponges

A sponge is a small, disposable device that is inserted into the vagina before intercourse. It works by blocking the cervix and releasing a spermicide to kill any sperm that may enter the vagina. Sponges are typically sold over the counter and do not require a healthcare professional to fit them.

One advantage of using a sponge is that it can be used when necessary, unlike other birth control methods like the pill, which need to be taken every day. Sponges can be used for up to 24 hours and can be easily removed afterward. The sponge does not need to stay in place for any post-sex time, unlike the diaphragm. However, sponges may not be as effective at preventing pregnancy as other forms of birth control and are best used with a backup method such as condoms.

Cervical Caps

A cervical cap is a small, cup-shaped device made of silicone that fits over the cervix. It works by blocking the cervix so that sperm cannot enter the uterus and fertilize an egg. Like a diaphragm, a cervical cap needs to be fitted by a healthcare professional.

One advantage of using a cervical cap is that it can be left in place for up to 48 hours, making it a good option for those who have difficulty remembering to use birth control. It can also be used with spermicide and can be placed up to two hours before intercourse. However, cervical caps need to be replaced every one to two years and may not be as effective as other forms of birth control.

While these methods of birth control may not be as widely used as other forms, each provides a non-hormonal option that can be effective with proper use. It’s essential to consider what works best for your lifestyle and needs when choosing a form of birth control. And always remember- condoms are the ONLY method of birth control that prevent STI transmission, so it’s important to use them in conjunction with any other birth control method to protect your sexual health.
