Diaphragm
Silicone cap, with a maximum diameter of 10 cm wide, which a woman puts into her vagina before having sexual intercourse. It prevents a woman from getting pregnant (it is a method of contraception). A diaphragm covers the entrance to the uterus (cervix) and prevents the man's semen from entering the uterus. To enhance protection, a gel is applied to the inside of the diaphragm to kill or inhibit sperm cells.
