I am not a fan of circumcision, but i am also not a fan of lying.
>The ancient method of performing metzitzah—metzitzah b'peh, or oral suction[37][38]—has become controversial. The process has the mohel place his mouth directly on the circumcision wound to draw blood away from the cut. The majority of Jewish circumcision ceremonies do not use metzitzah b'peh,[39] but some Haredi Jews use it.[40][41][42] It has been documented that the practice poses a serious risk of spreading herpes to the infant.[43][44][45][46] Proponents maintain that there is no conclusive evidence that links herpes to Metzitza,[47] and that attempts to limit this practice infringe on religious freedom.[48][49][50]
>The practice has become a controversy in both secular and Jewish medical ethics. The ritual of metzitzah is found in Mishnah Shabbat 19:2, which lists it as one of the four steps involved in the circumcision rite. Rabbi Moses Sofer (1762–1839) observed that the Talmud states that the rationale for this part of the ritual was hygienic — i.e., to protect the health of the child. The Chasam Sofer issued a leniency (Heter) that some consider to have been conditional to perform metzitzah with a sponge to be used instead of oral suction in a letter to his student, Rabbi Lazar Horowitz of Vienna. This letter was never published among Rabbi Sofer's responsa but rather in the secular journal Kochvei Yitzchok
