Since there was discussion of the relationship of toxicity and ACL
injuries, this has to be thrown into the mix:

Abstract
To determine whether canine ovariohysterectomy or orchiectomy affects
the prevalence of anterior cruciate ligament injury, we compared
injury rates of anterior cruciate ligaments of animals that had
gonadectomy and animals that were sexually intact as a function of
gender, breed, or size. Records of 3218 dogs treated in one
orthopaedic veterinary practice during a 2-year period were
retrospectively reviewed. Anterior cruciate ligament injury, diagnosed
by a history of acute hind limb lameness and by positive anterior
drawer test, was confirmed at the time of surgery. The prevalence of
anterior cruciate ligament rupture in all dogs was 3.48%. Females that
had ovariohysterectomy and males that had orchiectomy had a
significantly higher prevalence of anterior cruciate ligament rupture
than the sexually intact dogs. Larger dogs had an i ncreased
prevalence of anterior cruciate ligament injury compared with smaller
or medium-sized dogs, with the increased rupture rates for sterilized
animals holding across breeds and sizes. Sterilization of either
gender increased the prevalence of anterior cruciate ligament injury,
suggesting a potential effect of gonadal gender on prevalence of
injury of this ligament.
