Does a vasectomy provide protection against sexually transmitted infections (STIs)?

A vasectomy is a surgical procedure intended for permanent male contraception by cutting and sealing the vas deferens, the tubes that carry sperm. While it is effective in preventing pregnancy, it does not offer any protection against sexually transmitted infections (STIs). STIs can be transmitted through various means including sexual contact, regardless of whether sperm is present or not. Therefore, relying on a vasectomy alone does not safeguard against the risk of contracting or transmitting STIs.

In considering the other options, it becomes clear that they imply some level of STI protection that a vasectomy simply does not provide. Full protection against STIs, protection against certain types, or conditional protection when used with condoms are incorrect assertions regarding the effectiveness of a vasectomy in this context. For protection against STIs, the consistent and correct use of barrier methods, such as condoms, is recommended.
