My view is very simply this: If and when Metzitzah is done, it should be done using a sterile method (sterile tube, sterile gauze) that doesn't compromise the baby's safety on a bacterial/microbe/germ level. I've written extensively about this (see blog posts below)

The Contested Study from Pediatrics, August 2004 - when I say "contested" I mean by those who advocate Metzitzah be done with the mouth with direct oral contact, who particularly don't like Rabbi Tendler (see the Tz'irei Agudas Yisrael Link)

I don't know the author of this one from a "Science-Halacha" website (though I wholly think the 10th paragraph is an example of disgustingly racist behavior on the part of certain groups of the right-wing community, and that the "perfect record" claim is naive, false, and a total disregard of the recorded history)

There is an article in this journal which just came out
(Here is the article: "Is Metzitza bePeh Dangerous?" - Dr. Daniel Berman - thank you ES for the link!) - This is an example (in my opinion) of a physician who ignores evidence due to a "hashkafic" bias, much like the physician in the letter responding to my article at the top of this page.
