OBJECTIVE To evaluate the long-term risks and benefits of early-age gonadectomy, compared with traditional-age gonadectomy, among dogs adopted from a large animal shelter. DESIGN Retrospective cohort study. ANIMALS 1,842 dogs. PROCEDURE Dogs underwent gonadectomy and were adopted from an animal shelter before 1 year of age; follow-up was available for as long as 11 years after surgery. Adopters completed a questionnaire about their dogs' behavior and medical history. When possible, the…

Effect of age at gonadectomy on the probability of dogs becoming overweight.

Gonadectomized dogs had a greater risk of being overweight than did sexually intact dogs, but this risk was not influenced by age at gonadectomy.

Evaluation of the risk and age of onset of cancer and behavioral disorders in gonadectomized Vizslas.

The younger the age at gonadectomy, the earlier the mean age at diagnosis of mast cell cancer, cancers other than mast cell, hemangiosarcoma, lymphoma, all cancers combined, a behavioral disorder, or fear of storms.

Age at gonadectomy and risk of overweight/obesity and orthopedic injury in a cohort of Golden Retrievers

The data suggest that Gonadectomy at any age is a risk factor for overweight or obesity, but delaying gonadectomy until dogs are at least 6–12 months of age may help to decrease the risk for orthopedic injury.

Prevalence of Reproductive Disorders including Mammary Tumors and Associated Mortality in Female Dogs

Spayed (ES + LS) female dogs had a 4-fold decreased risk of dying from mammary cancer compared to intact females and in this low-sterilization rate population, MTs developed in 35.1% of female dogs over their lifetime and was the cause of death in half of them.

Early-age neutering in dogs and cats: advantages and disadvantages

Prepubertal gonadectomy is defined as the surgical sterilization of immature male and female animals aging from 6-to-14 weeks, and it is a less invasive, less traumatic surgery when performed prior

How spaying and neutering increases the risk of several long-term health problems including obesity, urinary incontinence, bladder stones, hypothyroidism, diabetes mellitus, hip dysplasia, cruciate ligament rupture, behavioral changes, cognition problems, and several forms of cancer are discussed.

Making a rational choice between ovariectomy and ovariohysterectomy in the dog: a discussion of the benefits of either technique.

Canine OVE can replace OVH as the procedure of choice for routine neutering of healthy female dogs, making OVE the preferred method of gonadectomy in the healthy bitch.

Desexing Dogs: A Review of the Current Literature

The evidence for a beneficial effect of desexing is stronger in female than in male dogs; however, there is significant variation between breeds and sexes, and more research is needed to further elucidate these differences.

Influence of Gonadectomy on Canine Behavior

Evaluating the effects of gonadectomy on dog behavior across time found no change was found in the eating behavior or weight of dogs of both groups of dogs, and differences in the reduction in the various types of behavior suggest that further studies of gonads role in behavior should be conducted.



Long-term risks and benefits of early-age gonadectomy in cats.

Gonadectomy before 5.5 months of age was not associated with increased rates of death or relinquishment or occurrence of any serious medical or behavioral condition and may provide certain important long-term benefits, especially for male cats.

Long-term outcome of gonadectomy performed at an early age or traditional age in cats.

Preubertal gonadectomy may be performed safely in cats without concern for increased incidence of physical or behavioral problems for at least a 3-year period after gonad surgery.

Effects of prepubertal gonadectomy on physical and behavioral development in cats.

Neutering cats at 7 weeks of age had similar effects on physical and behavioral development, compared with neutering at the more traditional age of 7 months, lending support to the concept of prepubertal gonadectomy, already performed by many animal shelters/humane organizations, as a method of enhancing the effectiveness of pet population control programs.


Diameter of the pre-pelvic urethra of female cats gonadectomized at 7 weeks of age was significantly smaller than that of intact females, which meant that complete penile extrusion was possible in all of the intact males at 22 months of age.

Age at gonadectomy had no effect on age and radial length at time of the growth plateau, and final radial length was significantly increased in all gonadectomized animals.

Factors relating to urine spraying and fighting in prepubertally gonadectomized cats.

It was found that male cats are more likely to spray and fight if they are in households with female cats than with other male cats, and age at the time of gonadectomy was not a factor in their tendency to spray or fight.

Effect of prepuberal and postpuberal gonadectomy on heat production measured by indirect calorimetry in male and female domestic cats.

These data suggest that resting metabolic rate in cats decreases after gonadectomy, suggesting that Gonadectomized animals fed in a manner similar to sexually intact animals may be predisposed to obesity and its sequelae.

Influence of orchiectomy on canine behaviour

Behavioural problems were the main reason for orchiectomy, unwanted sexual behaviour being the most common, together with roaming, aggression, and abnormal urination behaviour, and the clinical signs of testosterone-dependent disease in most of the dogs either decreased or disappeared afterOrchiectomy.

Associations between body condition and disease in cats.

Results of this study substantiate reports of health risks associated with excess body weight in cats and suggest efforts to reduce weight in heavy and obese cats can lead to reduced risks of diabetes mellitus, lameness, and soft-tissue injuries, and skin problems unrelated to allergies.
