Synonyms for Penis: 50 Medical, Polite, Slang, and Related Terms

Looking for another word for “penis”? The best alternative depends heavily on the context, level of formality, and meaning you want to convey. The medical term penis is already the standard anatomical word, while alternatives such as phallus may sound clinical, academic, or literary.

Terms such as male organ and male genital organ are descriptive or euphemistic, while member and manhood can appear in older, literary, or figurative language. Informal slang terms also exist, but they can be vulgar or inappropriate in professional settings. Importantly, not every related term is a true synonym: genitalia, for example, refers to the reproductive or sexual organs collectively rather than specifically to the penis.
