Hormone Overproduction in Ferrets

Hyperadrenocorticism 

 

Ferrets suffer from various hormonal disorders. And since ferrets mature sexually quickly -- as young as four months of age -- these disorders tend to show early in life.

 

In hyperadrenocorticism, the adrenal cortex overproduces the ferret's sex hormones -- progesterone, testosterone, and estrogen. This occurs in ferrets not yet spayed (or neutered) and at any age.

 

Symptoms and Types

 

The most common sight seen in ferrets affected by hyperadrenocorticism is hair loss, which begins on the tail and rump and progresses up the body, towards the head. In female ferrets, a swollen vulva and enlarged nipples may be seen. Male ferrets, on the other hand, develop an aggressive behavior and have difficulty urinating because of the enlarged prostate gland.

 

This disorder may sometimes severely elevate the level of estrogen in the blood, causing bone marrow suppression and a deficiency of blood cells, which can lead to several blood disorders.

 

Hyperplasia, adenoma, and adenocarcinoma are three grades of hyperadrenocorticism. The hormonal disorder begins as growth of cortical tissue, goes on to become a tumor and, if untreated, develops into cancer. The cancerous cells, however, do not usually spread outside the adrenal gland.

 

Diagnosis

 

Blood tests (concentrating on the ferret's hormonal levels) are used to diagnose this Hyperadrenocorticism. An enlarged gland on an Ultrasound can also be a good indicator of the disorder.
