When it comes to calculating risk of HIV transmission, some people can really get fixated on specific percentages. That's not something to condone. But it's still interesting -- and useful -- when studies use those percentages to shed new light on key topics in HIV transmission.

Furthermore, the secretion of blood from damaged rectal tissues can increase the risk for the insertive "top" partner, providing the virus a route of transmission through the urethra and tissues that line the head of the penis particularly under the foreskin. In their review of 16 different high-quality studies, researchers at the Imperial College and the London School of Hygiene and Tropical Medicine concluded that the per-risk act of HIV through condomless anal sex was roughly around 1.
