Ovulation Induction (OI)

  • Ovulation induction refers to a treatment during which medications are taken, either orally or via injections, to stimulate the ovaries to release an egg.
  • Who needs OI? Women who do not ovulate normally because they have polycystic ovary syndrome (PCOS), high prolactin levels, or abnormal hormonal secretion by the brain (hypothalamic amenorrhea).
  • Northwestern Medicine Fertility and Reproductive Medicine offers OI using oral medications (e.g., Clomid or Letrozole) or injectable medications (e.g., Bravelle, Follistim, or GonalF).
