Definition / general
  • Due to inadequate progesterone production (Wikipedia)
  • Historically was thought to be associated with infertility and spontaneous abortions, but now questioned (Obstet Gynecol Clin North Am 2004;31:727)
  • Lag of histologic endometrial date of 3+ days from actual postovulatory date (some say 2+ days)
  • Must be found in 2 consecutive cycles to be clinically significant
  • Relevance of this concept has been questioned (Hum Fertil (Camb) 2011;14:60)
  • Clomiphene citrate or human menopausal gonadotropins (hMG) to stimulate follicular growth; supplemental hCG to improve corpus luteum secretion of progesterone; additional progesterone after ovulation
Microscopic (histologic) description
  • Either immature endometrium or persistence of proliferative changes
  • May see dyssynchronous endometrium (dissociation between endometrial glands and stroma)
