[1996 report of in vitro fertilization with a third donor].

1996 results of French federation of CECOS and IFREARES-Toulouse are recorded. In 1996 13% less AID demands were registered. 4,132 patients underwent procreations with sperm donor during 11,793 cycles (AID and IVF D), resulting in 1,366 pregnancies. 386 volunteers men come forwards as sperm donors (40.3% less than 1995). The analysis of the 1,266 deliveries resulting of 1995 activity show always the same percentage of multiple births but an increase in intra-uterine AID malformations. The activity of semen preservation is increasing mainly for testicular cancer.
