Effects of glucagon-like peptide-1 on male reproductive function / 中华内分泌代谢杂志

ABSTRACT

With the younger onset of diabetes, the reproductive dysfunction caused by diabetes has received widespread attention. Hyperglycemia and insulin resistance, the main features of diabetes, are high-risk factors for male reproductive dysfunction. Obesity, the common co-morbidity of diabetes, may aggravate the progression of reproductive dysfunction. Glucagon-like peptide-1(GLP-1) and its receptor agonists improve the overall health status by lowering blood glucose, reducing body weight, and inhibiting inflammatory response, which indirectly exerts protective effects on the reproductive system. GLP-1 also protects reproductive function by regulating the neuroendocrine function, and directly acting on the supporting cells and interstitial cells of the testis. However, some studies did not find the protective effects. High-quality clinical studies are needed. GLP-1 receptor agonists may be a therapeutic option to improve reproductive dysfunction in diabetic men.
