Refractory period (sex) autonomic feedback mechanism, rather than through central chemicals like oxytocin, serotonin, and prolactin. Autonomic feedback is already known to regulate other physiologic systems, such as breathing, blood pressure, and gut motility. This theory suggests that after male ejaculation, decreased wall tension in structures such as the seminal vesicles leads to a change in the fine autonomic signals sent from these organs, effectively creating a negative feedback loop. Such a mechanism is similar to decreased gastric and bowel motility once gastric contents have passed through. Once the feedback loop has been created, the refractory period remains until the loop is broken
Adrenocorticotropic hormone (medication) per vial. As an off-patent pharmaceutical, a similar drug, differing in formulation, available in Europe, made by a different manufacturer, sells for $8 per vial. Acthar gel has been proposed as a therapy to treat refractory autoimmune diseases and refractory nephrotic syndrome due to a variety of glomerular diseases. Both versions of the hormone are also used to perform the ACTH stimulation test to diagnose hypoadrenocorticism in dogs and sometimes cats. Adrenocorticotropic hormone (medication) Adrenocorticotropic hormone is used as a medication and as diagnostic agent in the ACTH stimulation test. The form that is purified from pig pituitary glands is
