Cutting the risk of HIV transmission

Looks like male circumcision as a HIV transmission risk reduction method has been validated by two additional African studies:

In 2,784 men ages 18 to 24 in Kisumu, Kenya, researchers found the two-year HIV incidence was 2.1% in the circumcised men and 4.2% among controls -- a difference that was statistically significant at P=0.0065.

The risk reduction in the Kenyan trial was 53%.

In 4,996 men ages 15 to 49 in the rural Rakai district of Uganda, researchers found a two-year HIV incidence of 0.66 cases per 100 person-years in circumcised men and 1.33 cases per 100 person-years among controls, which was significant at P=0.006.
The risk reduction in Uganda was 51%.
