It is a plausible mechanism via which GLP-1 may lead to intake suppression since activation of GLP-1 via EX4 injection was shown to decrease the motivation to obtain food (Dickson et al., ad libitum fed rats indicating that this response is robust (Dickson et al., ad libitum condition in which some rats still choose to expend a significant amount of work for their sugar reward (high-responders)
In some cases, particularly with obstructive azoospermia or hormone-related causes, yes
This accessibility is one of phentermine biggest advantages and a major reason it remains widely prescribed despite the availability of more effective alternatives
Importantly, Hinton and colleagues showed that human IgG2 variants harboring Fc fragments with amino acid substitutions that increase their binding affinity towards human FcRn at specifically pH 6.0, but not pH 7.4, had prolonged plasma half-lives in non-human primates (NHPs) [104]

It has multiple actions including: potentiation of glucose-mediated insulin secretion mechanisms identified: increased -cell proliferation, resulting in an increase -cell mass (Fusco et al, 2017) stimulation of insulin biosynthesis at the translational level, helping to maintain -cell insulin stores and secretory capacity (Baggio & Drucker, 2007) because the GLP-1 effect is glucose-dependent (there is more insulin release when glucose levels are elevated, but less effect when glucose levels are normal), GLP-1 agonists have a lower risk for producing hypoglycemia compared to sulfonylureas (that chronically stimulate insulin release, independent of glucose concentration) suppression of postprandial glucagon release Evidence indicates that stimulation of pancreatic cells by GLP-1 increases their glucose sensitivity, resulting in less glucagon release at any glucose level (Baggio & Drucker, 2007)
