What is a preventive measure against sexually transmitted diseases?

Using condoms during sexual activity is a well-established preventive measure against sexually transmitted diseases (STDs). Condoms act as a barrier that helps prevent the exchange of bodily fluids, which is a primary way STDs are transmitted. They can significantly reduce the risk of infection from various STDs, including HIV, chlamydia, gonorrhea, and syphilis, among others.

While other strategies, such as practicing monogamy, can also contribute to reducing the risk of STDs, they do not provide the same level of protection as condoms, which actively block transmission during sexual intercourse. Regular medical check-ups, though vital for overall health and early detection of STDs, do not prevent transmission; they are more about management and treatment after potential exposure. The option regarding regularly consuming antibiotics is not a preventive measure and could lead to antibiotic resistance if misused. Hence, using condoms stands out as a directly effective strategy for preventing STDs.
