Menstrual Cycle Physiology: The Hypothalamic-Pituitary-Ovarian Axis Estrogen, when released: • Negatively feeds back on the hypothalamus and anterior pituitary to Decreased FSH production • Positively feeds back on the hypothalamus and anterior pituitary to Increased LH production Note: the hormones of the menstrual cycle vary in terms of when and how much they are secreted, according to the various phases of the cycle. This flow-chart is simply meant to capture the main players and their functions in the menstrual cycle, in as much detail as a medical student needs to know. #MenstrualCycle #pathophysiology #HPOA #HypothalamicPituitary #endocrinology #feedback
