Abstract
From a collaborative study of the French "Federation des CECOS" who collected the follow up of 11,535 pregnancies, the effect of parental age on the offspring is studied. A significant influence of the donor's age is demonstrated for the occurrence of trisomy 21 (37.4 +/- 7.8 vs 34.5 +/- 6.0; p < 0.05).
