[If] his upper lip protrudes beyond the lower one, or the lower one protrudes beyond the upper one, this is a blemish. One whose teeth have been extracted is unfit for reasons of appearance. [One] whose breasts hang down like a woman’s, [or] whose belly bulges, [or] whose navel protrudes, [or one] who is subject to epileptic seizures even rarely, [or] who is prone to severe melancholy, [or] one who has an enlarged scrotum, or an oversized membrum [is unfit]. One who has no testicles, or who has but one testicle, is the mero’ach ashech mentioned in the Torah. R’ Yishmael says: One whose testicles were crushed. R’ Akiva says: One who has wind in his testicles. R’ Chananiah ben Antignos says: One who has a dark complexion.
