Top Endocrine Publications of 2011: Canine and Feline Reproductive Endocrinology

In my 9th compilation of the canine and feline endocrine publications of 2011, I’m moving on to endocrine disorders of the canine and feline gonads and mammary gland.

Listed below are 11 research papers written in 2011 that deal with a variety of issues of clinical importance in reproductive endocrinology in dogs and cats.

These range from the investigation of male pseudohermaphroditism in dogs (1) to a report of persistent Müllerian duct syndrome (2); from tumors of the testes (8,11) to ovarian cysts (9) in dogs; from the effects of neutering on circulating concentrations of acute-phase proteins, adiponectin and IGF-1 in dogs (10) to studies investigating the interaction between IGF-1 and apoptosis-associated proteins on canine mammary gland tumors (7).

Finally, we have two papers on feline reproduction: the first (4) is a review of reproductive problems in both the queen (e.g., ovarian remnant syndrome, mammary fibroadenomatous hyperplasia, pregnancy diagnosis) and the tom (e.g., cryptorchidism, low libido). The other paper describes the use of deslorelin acetate, an injectable gonadotropin releasing hormone (GnRH) agonist, as a new way of achieving temporary suppression of estrus (5).
