The study's findings challenge conventional wisdom on the effectiven...
Three clinical trials in Africa found that adult male circumcision reduced HIV transmission by 51-60%. However, the impact on US populations is uncertain due to differing modes of transmission and circumcision prevalence. The CDC suggests considering circumcision as an additional prevention measure for high-risk men.
A recent study suggests that adult male circumcision could help prevent HIV transmission in the US, particularly among heterosexual couples. However, the effectiveness of circumcision in reducing HIV risk among men who have sex with men (MSM) is uncertain due to limited data and potential biases.
