  2. What is Estrogen • General name for a group of hormone compounds • Estrone, estradiol, estriol • Estrogen primarily comes from womens’ ovaries • Some estrogen is produced by other parts of the body like the liver, breasts, and adrenal glands. • Primary female sex hormone • Found in males, but more likely in girls • Steroid (if it is natural) • Synthetic Estrogen is non-steroidal

  4. Positive or Negative Feedback • Positive • occurs at high concentrations near end of follicular phase • Positive feedback triggers the anterior pituitary to release more FSH and LH • More FSH and LH cause the ovary to produce more estrogen • Negative • Occurs during follicular phrases when estrogen levels are low
