title: [Effects of ovulation induction therapies on endometrial integrin alpha v beta 3 expression in patients with polycystic ovarian syndrome related infertility].
abstract: OBJECTIVE
  To study the endometrial integrins alpha v beta 3 expressions during mid-luteal(ML) phase in polycystic ovarian syndrome (PCOS) related infertile patients receiving ovulation induction therapies.
  
  
  METHODS
  Immunohistochemical methods using monoclonal antibody against integrins alpha v beta 3 were performed on endometrium of ML phase obtained from 22 normal subjects and 40 PCOS related anovulatory patients who underwent ovulation induction therapy by one of the following regimens: clomiphene citrate (CC) + human chorionicgonadotropin (hCG), CC + human menopausal gonadotropin (hMG) + hCG, or gonadotropin-releasing hormone agonist + hMG + hCG.
  
  
  RESULTS
  The expressions of endometrial integrin alpha v beta 3 during ML phase in GnRHa + hMG + hMG + hCG cycles were similar with those in normal natural cycles, but were weaker in CC + hCG, CC + hMG + hCG cycles as compared with controls.
  
  
  CONCLUSIONS
  CC + hCG, CC + hMG + hCG regimens may induce decline of endometrial receptivity in ML phase.
