What is the difference between polycystic ovaries and multicystic ovaries?
Multicystic ovaries (multiple cysts of 25 mm) are a variation of normal physiology. These are associated with multiple births (twins, triplets, …). They happen commonly with ovulation induction (clomiphene, menopausal gonadotropins, FSH, …). These are associated with increased pain and with surgery to relieve the pain. These are contrasted with PCO and multiple cystic follicles. PCO (multiple follicles of about 8 mm at the rim of the ovary) is best described at: PCOSupport.org. Multiple cystic follicles (multiple follicles up to 10 mm) are part of normal ovulation. Return to top of page.
