Definition of Infertility in Male Dogs

In the most general sense, infertility in male dogs is the inability to sire a litter. In many cases, a dog’s failure to sire a litter is simply caused by bad timing, rather than sterility on the part of either prospective parent. Things that can cause infertility in dogs include underdeveloped testicles, retained testicles, cancer, castration, hypothyroidism, diabetes, pituitary gland abnormalities, adrenal gland disorders, testicular trauma or infection, anatomical defects, sexual overuse, fever and old age, among others. Psychological factors can also play a role; for example, dogs may develop an unpleasant association with mating if they are punished for showing sexual behavior (“humping”). Some of the potential causes of infertility are painful. However, most of the time male dogs with reproductive problems don’t show any particular signs of discomfort or distress.
