Diaphragm
Highlights
The diaphragm is a cup made of thin, fexible latex or silicone. It's placed inside your vagina and covers the cervix (the part of the uterus that opens into the vagina).This prevents sperm from getting in and fertilizing an egg. For added protection, spermicide is put inside the diaphragm before insertion. The diaphragm is fitted by your healthcare provider.2
