What complications can arise from untreated trichomoniasis?

Untreated trichomoniasis can lead to an increased risk of HIV transmission, which is the reason this choice is identified as correct. The presence of trichomoniasis can cause inflammation in the genital area, which opens pathways for the HIV virus to enter the body more easily during sexual contact. Additionally, individuals with trichomoniasis may have co-existing sexually transmitted infections, further compounding this risk.

Furthermore, untreated trichomoniasis can lead to other complications, although this particular choice stands out due to its significant implications for public health. Infertility in men could be a concern, but it is less commonly associated with trichomoniasis compared to its effects in women. Persistent itching and pelvic pain are symptoms that may occur but don’t highlight the serious risks associated with untreated infections, especially regarding the transmission of HIV. Hence, while the other complications are valid considerations, they do not carry the same critical public health concern as the increased risk of HIV transmission resulting from untreated trichomoniasis.
