abstract: OBJECTIVE
  Evaluating the rate of pregnancies, neonates, implantation rate and kinds of donor in our program Assisted Reproduction with oocyte donation.
  
  
  BACKGROUND
  The oocyte donation is the most important support in assisted reproduction because in patients with ovarian failure, offering the same opportunity to female without ovarian alterations to increase the rate of pregnancies.
  
  
  METHODS
  98 donor's procedures were included in host patients; 87 were FIV-TE and 11 GIFT between march to june 1997. The patients were divided in age group: 1) < 30 years, 2) 30 to 34 years, 3) 35 to 39 years, 4) > or = 40 years. The donors were divided in known (26) and unknown (72). The results were analysed.
  
  
  RESULTS
  48 pregnancies (55.17%) of the 87 FIV-TE-D group were obtained with 31 neonates The implantation rate was 17.5% to FIV-TE group and 13.8 to GIFT group, 44 (61.11%) pregnancies were from unknown donors group and 9 (34.61%) from known donors group.
  
  
  CONCLUSIONS
  Our results are similar to others international reports, we have observed a little and significative difference between pregnancy with oocytes from known donors and unknown donors; this is the principal motive to be selective in the suitable known donor.
