“…We conclude that in LRs, as in Lund's study, neutering impacts male obesity outcome significantly more than in females. It is perhaps unsurprising that there is a different effect of neutering between sexes, given that the hormonal changes resulting from orchiectomy (marked reduction in testosterone [31][32][33] ) are different from those in females. [34][35][36] The data implicate testosterone absence in the pathogenesis of obesity in neutered, male dogs.…”

BackgroundCanine obesity is a complex disease affected by genetic, endocrine and environmental factors. It is associated with reduced lifespan and many comorbidities. Prevalence differs by breed, with Labrador retrievers at high risk. Past data on how biological risk factors impact weight gain have been contradictory, possibly because they were obtained from genetically heterogeneous populations.MethodsWe investigated risk factors for canine obesity in a population of British Labrador retrievers (n = 521) with high‐quality data on obesity, weight, owner‐reported food motivation and related characteristics. We used linear regression to assess known and novel risk factors for obesity.ResultsWe found that neutering increased obesity in males (p < 0.001) but not females (p = 0.37). Older age was associated with obesity in female Labradors (p = 0.013) but not males (p = 0.49). We identified two new risk factors for obesity in Labrador retrievers: chocolate coat colour (p < 0.001) and high food motivation (p < 0.001).LimitationsStrategic recruitment to collect both obese and lean dogs means this cohort is not suitable for assessing obesity prevalence in UK Labrador retrievers.ConclusionStudying this genetically homogeneous population informs our knowledge of common risk factors for obesity and expands those relevant to Labrador retrievers.

“…However, in one experimental study with dogs, vasectomy was shown to induce testicular damage and thus may not be reversible ( 201 ). A new technique called ‘laparoscopic castration’ and ‘vasoligation’ was introduced for use in dogs, whereby ligation or fusion of the tissues is performed on the vas deferens and/or the testicular blood vessels, without removing the testes ( 202–204 ). This method caused total testicular atrophy and epididymal fibrosis, with testosterone concentrations equivalent to that after surgical castration.…”

Sterilization and castration have been synonyms for thousands of years. Making an animal sterile meant to render them incapable of producing offspring. Castration or the physical removal of the testes was discovered to be the most simple but reliable method for managing reproduction and sexual behavior in the male. Today, there continues to be global utilization of castration in domestic animals. More than six hundred million pigs are castrated every year, and surgical removal of testes in dogs and cats is a routine practice in veterinary medicine. However, modern biological research has extended the meaning of sterilization to include methods that spare testis removal and involve a variety of options, from chemical castration and immunocastration to various methods of vasectomy. This review begins with the history of sterilization, showing a direct link between its practice in man and animals. Then, it traces the evolution of concepts for inducing sterility, where research has overlapped with basic studies of reproductive hormones and the discovery of testicular toxicants, some of which serve as sterilizing agents in rodent pests. Finally, the most recent efforts to use the immune system and gene editing to block hormonal stimulation of testis function are discussed. As we respond to the crisis of animal overpopulation and strive for better animal welfare, these novel methods provide optimism for replacing surgical castration in some species.
