Beyer T, Rink B, Scarlet D, Walter I, Kunert S, Aurich C. Early luteal phase progestin concentration influences endometrial function in pregnant mares. Theriogenology. 2018;125:236-241 pubmed publisher
..This influenced endometrial function as reflected in lower concentrations of the amino acids lysine and isoleucine in endometrial secretions. Enhanced progestin concentration had less clear effects in healthy fertile mares. ..
Gautier C, Schmidt K, Aurich J, Aurich C. Effects of implants containing the GnRH agonist deslorelin on testosterone release and semen characteristics in Shetland stallions. Anim Reprod Sci. 2018;: pubmed publisher
..In conclusion, deslorelin implants modulate pituitary function in stallions but not to an extent that affects testicular function. ..

. Reproductive stage and sex steroid hormone levels influence the expression of mesenchymal stromal cell (MSC) markers in the equine endometrium. Theriogenology. 2018;116:34-40 pubmed publisher
..In conclusion, our results suggest that levels of MSC markers in equine endometrium dynamically change across reproductive cycles and that MSC populations are in part regulated by sex steroids. ..

..Results of the present study provide only little evidence that maternal tolerance of pregnancy in the horse is modulated already by exposure of the oestrous endometrium to seminal plasma at mating. ..
Schrammel N, Deichsel K, Aurich J, Aurich C. A long-day light program accelerates seasonal coat changes but is without effect on semen and metabolic parameters in Shetland pony stallions. Theriogenology. 2016;85:946-953 pubmed publisher
..In conclusion, Shetland stallions showed seasonal variations in hair coat and total sperm count but only changes in hair coat but not semen parameters were advanced by a long-day light program. ..

..In conclusion, motility of cooled-stored semen was reduced in January and increased in stallions kept under a long day light programme for at least 30 days. ..
Aurich C, Schreiner B, Ille N, Alvarenga M, Scarlet D. Cytosine methylation of sperm DNA in horse semen after cryopreservation. Theriogenology. 2016;86:1347-52 pubmed publisher
..The lower fertility rates of mares after insemination with frozen-thawed semen may at least in part be explained by cytosine methylation of sperm-DNA induced by the cryopreservation procedure. ..
