unneutered

Sense: adjective/1
'Intact' is the most clinical term, common in veterinary records and surgical consent forms — it sounds neutral and professional. 'Unneutered' is the everyday standard in animal welfare and shelter contexts, widely understood by the general public. 'Unfixed' is informal and mainly American; you would hear it in casual conversation at a dog park but rarely see it in a vet's written notes. 'Whole' is vaguer — it can describe an animal that has not been neutered, but it more often means 'not broken' or 'complete'. For example, a shelter worker might say 'We only adopt out unneutered animals to approved breeders', while a vet writes 'intact male' on a chart, and a neighbour might ask 'Is your dog still unfixed?'

Etymology
Formed in modern English by adding the negative prefix 'un-' to 'neutered', the past participle of the verb 'neuter'. 'Neuter' entered English from Latin 'neuter' meaning 'neither', originally a grammatical term for verbs that are neither active nor passive, then later (19th–20th century) extended to animal surgery.
