Terms such as "male nurse", "male model" or "female judge" are sometimes used in cases where the gender is irrelevant or already understood (as in "my brother is a male nurse"). Many advisors on non-sexist usage discourage such phrasing, as it implies that someone of that gender is an inferior or atypical member of the profession. Another discouraged form is the prefixing of an ordinary job title with "lady", as in "lady doctor": here "woman" or "female" is preferred if it is necessary to specify the gender.
