Lactation of suckling by the baby. The milk ejection reflex (also called let-down reflex) is not always consistent, especially at first. Once a woman is conditioned to nursing, let-down can be triggered by a variety of stimuli, including the sound of any baby. Even thinking about breastfeeding can stimulate this reflex, causing unwanted leakage, or both breasts may give out milk when an infant is feeding from one breast. However, this and other problems often settle after two weeks of feeding. Stress or anxiety can cause difficulties with breastfeeding. The release of the hormone oxytocin leads to the "milk ejection" or
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
