Infertility is the inability to get a female dog pregnant. In male dogs, infertility can be caused by a variety of factors
If you think your dog may be infertile, the veterinarian will perform a physical exam and may recommend some diagnostic tests.
The treatment for infertility in male dogs depends on the underlying cause.
The age of the male dog is a major factor in fertility. Older dogs are less likely to get females pregnant than younger dogs.
Structural abnormalities, such as a blocked or damaged vas deferens, can also prevent a male dog from getting a female dog pregnant.
Some infections, such as brucellosis, can also cause infertility in male dogs.
Some medications, such as steroids, can also affect a male dog's fertility.
