What are Diaphragms?

​A diaphragm is a barrier contraceptive device that covers the cervix to block sperm from entering. It is a cup made of soft latex, plastic, or silicone with a firm, flexible rim placed deep in the vagina before sex to prevent sperm from being able to reach an egg.

Users may like using a diaphragm as a contraceptive as it does not release any hormones, and is simply placed before engaging in sexual activity. There are no side effects with this contraceptive. Many users choose to use a diaphragm with spermicidal cream, jelly, or foam to improve effectiveness.

To ensure proper efficacy, users should undergo a pelvic exam to receive a proper fitting diaphragm for their cervix. When correctly used, about 16 pregnancies per 100 women occur with the addition of spermicide. As commonly used, about 17 pregnancies per 100 women occur with the additional use of spermicide.

We hope that all people can find a contraceptive option that works for them. For those interested in non-hormonal, reversible options, a diaphragm for people with vaginas may be a good option. For people with penises, MCI is working on the research and development of non-hormonal, reversible options now.
