Final answer:
The contraceptive device that can cause Toxic Shock Syndrome (TSS) is the diaphragm, which is a barrier method of contraception.
Step-by-step explanation:
The contraceptive device that can cause Toxic Shock Syndrome (TSS) is the diaphragm. TSS is a rare but serious medical condition that is most commonly associated with tampon use, but it can also occur with the use of barrier methods of contraception, such as diaphragms, if they are left in place for extended periods of time. Diaphragms work by covering the cervix to prevent sperm from entering the uterus, and when combined with spermicides, they can increase their effectiveness. However, women should always follow the recommended guidelines for use to minimize the risk of TSS and other potential infections.
