The regulation of reproductive processes includes integrating various factors from structural functions and environmental conditions in the HPG axis, with the outcome indication of these processes being the pulsatile secretion of gonadotropin\u2010releasing hormone (GnRH) from the hypothalamus. These factors include feed consumption and nutritional condition, sex steroids, season\/photoperiod, pheromones, age, and stress. GnRH pulsatile secretion affects the pattern of gonadotropin secretion of follicle\u2010stimulating hormone (FSH) and luteinizing hormone (LH), which then regulates both endocrine function and gamete maturation in the gonads. This regulates gonadotropins and testosterone (T) production. There is evidence that in males, GnRH participates in a variety of host behavioural and physiological processes such as the release of reproductive hormones, progression of spermatogenesis and sperm function, aggressive behaviour, and physiological metabolism. GnRH activates receptors expressed on Leydig cells and Sertoli cells, respectively to stimulate T secretion and spermatogenesis in the testis. Photoperiod affects the reproductive system of the hypothalamic\u2010pituitary axis via rhythmic diurnal melatonin secretion. Increased release of melatonin promotes sexual activity, GnRH production, LH stimulation, and T production. This induces testicular functions, spermatogenesis, and puberty. GnRH reduces the release of LH by the pituitary through the cascade effect and decreases plasma concentration of T. Gut microbiota maintain sex steroid homeostasis and may induce reduction in reproduction productivity. Recently, findings of kisspeptin\u2010neurokinin\u2010dynorphin neuronal network in the brain have resulted in fast advances in how GnRH secretion is controlled. Emerging studies have also indicated that other neuropeptide analogues could be used in control reproduction procedures in various goat and sheep breeds. The Tibetan male sheep and goats reproduce on a seasonal basis and have high reproductive performance. This is a review for the role of GnRH in Tibetan male sheep and goats reproduction. This is intended to enhance reproductive knowledge for understanding the key roles of GnRH relating to male reproductive efficiency of Tibetan sheep or goats.<\/jats:p>","DOI":"10.1111\/rda.14432","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T07:59:01Z","timestamp":1690358341000},"page":"1179-1187","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":31,"title":["The role of<scp>GnRH<\/scp>in Tibetan male sheep and goat reproduction"],"prefix":"10.1111","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6339-329X","authenticated-orcid":false,"given":"Wangsheng","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Life Science and Engineering Southwest University of Science and Technology Mianyang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Adjei","sequence":"additional","affiliation":[{"name":"School of Life Science and Engineering Southwest University of Science and Technology Mianyang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenzhen","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Life Science and Engineering Southwest University of Science and Technology Mianyang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenjie","family":"Yuan","sequence":"additional","affiliation":[{"name":"Institute of Animal Science, Tibet Academy of Agricultural and Animal Husbandry Science Lhasa China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuoma","family":"Cisang","sequence":"additional","affiliation":[{"name":"Institute of Animal Science, Tibet Academy of Agricultural and Animal Husbandry Science Lhasa China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianzeng","family":"Song","sequence":"additional","affiliation":[{"name":"Institute of Animal Science, Tibet Academy of Agricultural and Animal Husbandry Science Lhasa China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,7,26]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1515\/aoas-2015-0031"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.anireprosci.2005.05.006"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/dey116"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/jez.1765"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0093-691X(00)00353-8"},{"key":"e_1_2_13_7_1","first-page":"5","volume-title":"Sheep and goat production handbook for Ethiopia: Ethiopia sheep and goat productivity improvement program (ESGPIP)","author":"Alemu Y.","year":"2008"},{"key":"e_1_2_13_8_1","volume-title":"Applied animal reproduction","author":"Bearden H.
