Advantages and disadvantages of the diaphragm

Advantages

The diaphragm can be carried in a purse, can be inserted up to two hours before intercourse begins, and usually cannot be felt by either partner. It also does not interfere with a woman's hormones.

Disadvantages and complications

Common complications when using a diaphragm are that some women dislike having to insert the device every time they have intercourse, or have trouble mastering the insertion and removal process. The diaphragm can also be dislodged during sex and the failure rate is high, about 16%. Additionally, the diaphragm does not protect against STIs. Frequent urinary tract infections and vaginal infections can be a problem for some women when using a diaphragm.
