title: Endometrial receptivity in terms of pinopode expression is not impaired in women with endometriosis in artificially prepared cycles.
abstract: OBJECTIVE
  To assess endometrial receptivity in terms of pinopode expression in women with endometriosis.
  
  
  METHODS
  Prospective, observational study.
  
  
  METHODS
  Oocyte donation program at the Instituto Valenciano de Infertilidad.
  
  
  METHODS
  Twelve women with endometriosis as the only cause of infertility.
  
  
  METHODS
  Pinopode expression pattern analysis by scanning electron microscopy in two sequential endometrial biopsies obtained in the same cycle of each patient.
  
  
  METHODS
  Pinopode pattern and pregnancy rates.
  
  
  RESULTS
  Pinopode expression in women with endometriosis did not differ from that of patients without endometriosis undergoing artificial cycles. Similarly, the clinical outcome in these women was comparable to that of the general population included in the oocyte donation program. The pregnancy rate per transfer was 46.7%.
  
  
  CONCLUSIONS
  These results show that in women with endometriosis undergoing oocyte donation under hormone replacement therapy, pinopode expression is not altered, suggesting that endometrial receptivity in women with this disease remains unaltered.
