title: Increasing the dosage of progesterone (P) supplemention from the mid-luteal phase in women not attaining a mid-luteal homogeneous hyperechogenic (HH) pattern with sonography improves pregnancy rates (PRS) following frozen embryo transfer (ET).
abstract: OBJECTIVE
  To determine if a mid-luteal phase non-homogeneous hyperechogenic (HH) endometrial echo pattern may lower pregnancy rates following frozen embryo transfer and to determine if raising the dosage of progesterone improves pregnancy outcome.
  
  
  METHODS
  Women not attaining an HH pattern at the mid-luteal phase following estrogen-progesterone replacement were randomly given (or not) an increase in progesterone dosage.
  
  
  RESULTS
  Increasing the progesterone dosage in those not attaining an HH pattern significantly improved the pregnancy rate relative to controls not attaining an HH pattern and showed a trend for higher pregnancy rates than those with an HH pattern.
  
  
  CONCLUSIONS
  The mid-luteal phase echo pattern should be evaluated for a non-HH pattern so that an increase in progesterone dosage could be provided possibly resulting in higher pregnancy rates.
