infertility in dogs


Review of the Proceedings of the Annual Conference of the Society for Theriogenology on causes of dog infertility and its implications

Infertility in dogs is not uncommon and it leads to a progressive financial damage to the canine (the dog, not the teeth) breeding industry. Particularly the infertility in the male dog is worrisome.

Individual assessment of a dog's fertility is essential and requires a thorough examination of its history with emphasis on general health and past reproductive performance. Prostate gland or testicular dysfunction can only be ascertained with a comprehensive breeding soundness evaluation (BSE). An important aspect of the BSE test is the collection and testing of the [ENC]semen[/ENC].

The term cryptorchid means hidden testis and it is a common phenomenon among certain population in Western nations such as the USA and Australia. Also in dogs it occurs frequently.

The biggest question in cases of cryptorchidism is always; "how long do I have to wait before i can be sure the testis will not descend in its proper place". And indeed there are no easy answers to this question, although normally this process is accomplished after 10 days after birth. However, since the testes of puppies are small, soft to the touch and can still easily move it is suggested to wait at least 6 months before making a final diagnosis.

Small dog breeds suffer more from cryptorchidism than large breeds, probably due to the gravitational effect on testes descent.


Azoospermia is an ejaculate, or semen, devoid of spermatozoa; only seminal plasma is present. Once can imagine it is difficult to fertilize an egg without any sperm cells present in the semen.
The general public may laugh at this affliction, but the latest figures show that up to 35% (!!!!) of all dogs suffer from it. It is essential to keep in mind that only a proper diagnosis can be made by collecting semen in the presence of estrual bitch. Collections made under different circumstances do not give a reliable estimate.

Prostate disorders

Prostrate disorders are common in many Western nations, especially in nations such as the USA and Australia. Also in dog it is a frequent problem that can lower the fertility of the male dog. The prostrate is a walnut-shaped gland that is located caudal to the urinary bladder. Hypertrophy of the prostrate gland is quite common in dogs with more than 80% of dogs older than 5 years suffering from it to some degree.

Prostate inflammation and infection

Prostate inflammation is usually caused by a bacterial infection and very painful. It's more common in dogs that show hypertrophy of the prostrate gland. Antibiotics should be given for 4-6 weeks and if the prostrate is hypertrophic the dog should be castrated since it will probably come back again. It's not recommended to follow these guidelines for human patients.

This is about the state of health that an environment projects outwards.
Dogs should have no reason for not being able to reproduce. They have been able to reproduce ever since the first dogs came into existence.

The environment is unhealthy for proper reproduction of some dogs. It is said the same will be for the humans that live in western societies. Which wont be a problem because we are already over-populated. But that will end quick if we cant properly reproduce.
It is predicted that 1 in 3 men will get prostate cancer in their lifetime.

What kind of studies do we have on the safety of cell towers? I see them all over the place. And cell towers are mainly used by developed countries who are experiencing these kind of problems.
Since dogs are happy to breed every chance they get, this might be a way of keeping the canine population down?
Dogs eat shit, and chew baby's faces off while they sleep.

If there is any reason to research infertility in dogs, it's to stop them from breeding altogether. Dogs have no purpose in modern society other than annoying postmen and leaving shit all over the road for you to step in.
