Exploring behavioral outcomes of gonadectomy in pets: a need for personalized approaches.
Review in Animal reproduction, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Gonadectomy, the surgical removal of reproductive organs-is commonly practiced in canine management and is often associated with responsible pet ownership. Although advised for preventing unwanted litter and specific health hazards, its effects on canine behavior remain contentious and little studied. This article analyzes the physiological and behavioral effects of gonadectomy in dogs, emphasizing other sexually dimorphic behaviors including mounting, wandering, and urine marking, alongside aggression, fear, anxiety, separation-related issues, and canine cognitive dysfunction. Gonadectomy impacts hormonal equilibrium by modifying the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes, hence affecting stress responses, cognition, and behavior. Certain research indicates that neutering diminishes urine marking and roaming; nevertheless, the results are inconsistent. Conflicting research suggests that gonadectomy may intensify aggression, fearfulness, and anxiety, thus undermining the human-animal bond. The effects of gonadectomy on cognitive impairment remain ambiguous. Alternative methods, including vasectomy, ovary-sparing spay, and chemical castration, provide reproductive regulation while maintaining hormonal function, potentially alleviating negative behavioral consequences. Due to the complex aspects of behavioral development, encompassing heredity, environment, and personal experiences, a general policy on gonadectomy is unsuitable. This review highlights the necessity of personalized assessments when advising gonadectomy for behavioral management in canines. Veterinarians must meticulously evaluate the advantages and disadvantages, considering the unique circumstances of each animal and seeking guidance from veterinary behaviorists, as necessary. Routine desexing should not be universally advocated only for the purpose of mitigating behavioral issues. Additional research is crucial to comprehend the intricate link between gonadectomy and canine behavior.
