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
Corticotropin-releasing hormone receptor 1 II and urocortin III. Variations in the "CRHR1" gene is associated with enhanced response to inhaled corticosteroid therapy in asthma. CRF1 triggers cells to release hormones that are linked to stress and anxiety [original reference missing].Hence CRF1 receptor antagonists are being actively studied as possible treatments for depression and anxiety. Variations in CRHR1 are associated with persistent pulmonary hypertension of the newborn. Corticotropin-releasing hormone receptor 1 has been shown to interact with Corticotropin-releasing hormone and Urocortin. Corticotropin-releasing hormone receptor 1 Corticotropin-releasing hormone receptor 1 (CRHR1) is a protein, also known as CRF, with the latter (CRF) now being the IUPHAR-recommended
