atc code g03 atc code g03 atc code g03 sex hormones and modulators of the genital system is a therapeutic subgroup of the anatomical therapeutic chemical classification system, a system of alphanumeric codes developed by the world health organization (who) for the classification of drugs and other medical products. subgroup g03 is part of the anatomical group g genito-urinary system and sex hormones. atc codes g genito-urinary system and sex hormones g01 gynecological antiinfectives and antiseptics g02 other gynecologicals g03 sex hormones and modulators of the genital system g04 urologicals atcvet only qg51 antiinfectives and antiseptics for intrauterine use qg52 products for teats and udder a b c d g h qi j l m n p r s v codes for veterinary use (atcvet codes) can be created by placing the letter q in front of the human atc code: for example, qg03. atcvet codes without corresponding human atc codes are cited with the leading q in the following list.national issues of the
