male

male is used as a noun only in technical writing (medicine, statistics, police reports, sociology), most often reserved for biological or nonhuman references. When using "male" as a noun, beware of nonparallel constructions, for example, "three women and two males." As an adjective, use "male" only when you would use "female" or when it is necessary for clarification; this adjective is often inserted gratuitously, for example, "male nurse," "male secretary," "male model," "male prostitute." And again, watch for nonparallel usage, for example, "three male dancers and one woman dancer."
