Top Endocrine Publications of 2014: Canine and Feline Reproductive Endocrinology

As I've done for the last 5 years, I’ve now finished compiling a fairly extensive list of references concerning canine and feline endocrinology that were written last year (in 2014). I’ll be sharing these with you over the next few months, as well as reviewing a few of the best papers from my lists of clinical endocrine publications.

In my last post, I provided my last list for the 2013 papers on canine and feline endocrine reproduction, so I've decided to start this year off with papers that deal with the same theme of endocrine disorders of the canine and feline gonads, prostate, and mammary gland.

Listed below are 23 papers published in 2014 that deal with a variety of topics of importance for reproductive endocrinology in dogs and cats. These range from the identification and study of kisspeptin (a protein ligand that activate GnRH neurons) in dogs (1) to the use of relaxin measurements to diagnose pregnancy status (2); as well as from a study of the effects of GnRH agonist and antagonists during the postnatal period in cats (3) to the effects of GnRH immunization for treatment of urinary incontinence in spayed bitches (4).

Other publication included studies dealing with suppression of fertility in dogs and cats (4-6,12,13,14,21) to endocrinologic investigations of pyometra (9), ovarian cysts (10), mammary neoplasia (16,19), and benign prostatic hyperplasia and prostatitis (17); and finally, from a study of oxytocin and social bonding in dogs (20) to a review of the influence of sex hormones on seizures in dogs and man (22).
