It was our objective to check the morphometry of some internal organs in rats’ offsprings with  retarded intrauterine growth by comparing them with a control group. The retarded intrauterine growth was induced by ligation of the uterine artery in both horns on the 16^th day of gestation in Sprague Dawley rats. The offsprings are studied at birth, and on the 7^th, 14^th and 21^st day. The weight and volume of the kidneys, liver, heart, lungs and intestine were verified. The weight and volume of the organs showed lower values compared with the control group in all the  times studied. It was observed that the reduction of the blood flow in the last week of pregnancy produced organic alterations in the examined offsprings that were maintained until weaning.
