Does diaphragms prevent sti

Diaphragms are primarily designed as a barrier method of contraception to prevent pregnancy by covering the cervix and blocking sperm from entering the uterus. However, they do not effectively prevent the transmission of sexually transmitted infections (STIs). To reduce the risk of STIs, it's recommended to use condoms in conjunction with diaphragms. Condoms are the only barrier method that provides significant protection against STIs.
