The Circumcision Decision 

The Circumcision Decision is a pretty comprehensive website with access to loads of what seems like pretty unbiased information. There are links to Youtube videos, news articles, book recommendations as well as information sorted by topic. The website was created following the success of the book The Circumcision Decision by Susan Terkel and Lorna Greenburg.

American Academy of Pediatrics

If you're looking for a science-based article that includes medical terminology check this article out. The AAP is the leading authority in pediatric medicine. Here is a link to the web page regarding the Circumcision Policy Statement. It was originally released in 1999 and revised in 2012. From what I can tell, the AAP has not released a new policy statement on circumcision since 2012.

Here is a link directly to the PDF of the Policy Statement on Circumcision.
