Secretion of Prolactin is affected by:
B i.e. Dopamine Dopamine acts as hypothalamic prolactin inhibiting hormoneQ and decreases prolactin secretion. L - DOPAQ Decreases prolactin release by formation of dopamine BromocriptineQ (& Dopamine agonists) Inhibits prolactin releas by stimulating dopamine receptors. ChlorpromazineQ (& Dopamine antagonist) Enhances prolactin release by blocking dopamine receptors Factors enhancing prolactin secretion: Nu - Nursing S - StressQ S - Sexual intercourse P - PregnancyQ S - Strenuous excerciseQ H - Hypoglycemia E - EstrogenQ S - Breast stimulationQ in non- H - HypothyroidismQ T - TRHQ lactating women 0 - OpiatesQ S - SomatiostatinQ S - SleepQ P - PhenothiazineQ
