A silicone cup that prevents pregnancy.
Prescription onlyNo hormones
Our pharmacists’ bottom line
The diaphragm is easy to use, but needs to be inserted into the vagina correctly. It's most effective (and recommended) when used with a spermicide, which can be irritating and messy.

- Very simple to use, and safe for most women.
- Doesn't contain hormones, which some women prefer.
- Usually inexpensive, and can be used for up to 2 years.
- You can get one easily OTC or online with a prescription. Your health provider might even have them in stock.

- Requires a prescription, and sometimes a fitting (depending on which diaphragm you get) that can cost up to $200 without insurance.
- Not recommended for use during your period – best to use another method of birth control around this time.
- Might take some practice to insert and remove it correctly.
- Must be left inside the vagina for 6 hours after sex in order for it to work.
- You have to be comfortable with your body since you insert and take it out on your own.
