Sexually transmitted diseases can be transmitted through oral sex

Most people deal with sexually transmitted infections at some point. For example, chlamydia, herpes, fungal diseases and genital warts are widespread. But gonorrhea and syphilis are also becoming more common today. The possible consequences range from annoying itching to life-threatening illness. If venereal diseases are detected, they can be treated well.

The most important thing about STDs

  • STDs are transmitted through sex. These are, for example, chlamydia, gonorrhea, and syphilis.
  • These are transmitted especially during vaginal, anal and oral sex, but also in other practices, for example in the sharing sex toys.
  • Condoms reduce the risk of infection, but not completely protect.
  • Venereal diseases often do not cause symptoms. If symptoms occur, these are for example Discharge, itching, or skin changes on the genitals and anus.
  • As a rule STDs can be treated well with antibiotics. Untreated they can have serious health consequences.
  • Anyone who is sexually active and has changing partners should therefore get tested regularly for sexually transmitted diseases.

You can protect yourself against some infections, for example with condoms or a vaccination. All of the diseases mentioned are easily treatable. Anyone who has sex with changing partners should therefore have themselves checked for undetected infections once a year.

This is especially true for people with untreated HIV infection: Some diseases can be more severe for them. Sexually transmitted infections can also increase the risk of contracting HIV because inflammation makes it easier for the virus to enter the body. If untreated HIV-positive people have another sexually transmitted infection, their partner's risk of contracting HIV increases.
