The numbers should help "reassure the large majority of men that the size of their penis is in the normal range," said British researchers who had assembled data from studies where participants had their member measured by a professional. In the worst cases, men may be diagnosed with Body Dysmorphic Disorder -- a debilitating psychological condition that can lead to obsessive and anti-social behaviour, depression and even suicide. The study participants were men aged 17-91 who had their penises measured in 20 previously published studies conducted in Europe, Asia, Africa and the United States. The team found no evidence for penis size differences linked to race, though most of the study participants were of European and Middle Eastern descent and a full comparison could thus not be made.

The United States is sending a team of federal investigators to Bangladesh to help probe the murder of a visiting American blogger by suspected Islamist militants, Dhaka police said Tuesday. Avijit Roy, known for his anti-religious blog posts and books including the best-selling "The Virus of Faith", was hacked to death with a machete as he returned home from a book fair with his wife in Dhaka last Thursday. Bangladesh's elite security force on Monday arrested radical Islamist Farabi Shafiur Rahman, the chief suspect in the murder, who they say sent Roy several death threats.
