title: An evaluation of the efficacy of using oocyte donors aged 36-39.
abstract: OBJECTIVE
  To determine if oocyte donors aged 36-39 can provide adequate pregnancy rates for recipients.
  
  
  METHODS
  Retrospective analysis of clinical, ongoing/delivered pregnancy and implantation rates for a group of recipients receiving oocytes from a pilot group of older donors.
  
  
  RESULTS
  Comparable pregnancy and implantation rates were found in recipients transferring embryos derived from donors aged 36-39 as recipients using oocytes from donors < or = 35.
  
  
  CONCLUSIONS
  The demonstration of adequate outcome following embryo transfer from embryos derived from fertilization of oocytes from donors aged 36-39 should expand the pool of donor oocytes and reduce the long waiting times for recipients.
