Top Endocrine Publications of 2010: The Canine and Feline Reproductive Endocrinology

 Fertility axis. GnRH, LH & FSH
stimulate secretion of testosterone,
progesterone, estrogen, & inhibin.
Controlled via negative feedback
on hypothalamus & pituitary gland.

In my 9th compilation of the canine and feline endocrine publications of 2010, I’m moving on to endocrine disorders of the canine gonads and mammary gland.

Listed below are 9 research papers written in 2010 that deal with a variety of issues of clinical importance in reproductive endocrinology in dogs.

These range from the investigations of the pituitary-ovarian axis in dogs with a functional granulosa cell tumor (1) to studies of the expression of estrogen and progesterone receptors in sebaceous gland tumors (2); and from studies of gonadotropin-releasing hormone (GnRH)-agonist implants in the treatment of reproductive disorders in the male dog (3) to a review of non-surgical methods for reproductive control in cats (4).

Finally, a number of studies investigate markers of malignancy for mammary gland tumors (6,7,8). Finally, the last paper reviews alternative ways to treat benign prostatic hyperplasia, including hormonal suppression of testicular function with GnRH-depot-analogues, inhibition of the 5-alpha-reductase, or peripheral androgen action with anti-androgens (9).
