________ is a sexually transmitted infection that damages organs after they have formed, rather than affecting organogenesis.

The condition you're referring to is likely syphilis. Syphilis is a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. Unlike some other STIs that can affect organ development during pregnancy (organogenesis), syphilis primarily damages organs and tissues after they have developed.

In its primary and secondary stages, syphilis can lead to symptoms such as sores, rashes, and flu-like symptoms. If left untreated, it can progress to late stages, potentially affecting the heart, brain, and other essential organs. It's crucial for sexually active individuals to engage in regular testing and practice safe sex to prevent the spread of STIs like syphilis. Treatment typically involves antibiotics, which are very effective, especially in the earlier stages of the infection.
