Infertility is the inability to get a female dog pregnant. In male dogs, infertility can be caused by a variety of factors, including: Age, Health problems, Hormonal imbalances, etc.
The veterinarian will perform a physical exam and may recommend some diagnostic tests, such as: Semen analysis, Blood tests, Ultrasound, etc.
The treatment for infertility in male dogs depends on the underlying cause. Some possible treatments include: Medications, Surgery, Assisted reproductive technologies, etc.
Hormonal imbalances can also cause infertility in male dogs, such as: Hypothyroidism, Hyperadrenocorticism, Diabetes mellitus, etc.
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.
In some cases, assisted reproductive technologies (ART), such as insemination or IVF, may be used to help a male dog get a female dog pregnant.
