[Fetal growth reduction in relation to location in the uterine horn. Experimental model in the rabbit].

We studied the differences in weight of fetal body and organ growth in 35 pregnant rabbits in which intrauterine fetal growth retardation was induced with a microsurgical technique, in relation to fetal position in the uterine horn, and compared with a control group (88 rabbit). No differences was found in control group between gestational age and in relation to fetal position. There is a highly significant difference (p less than 0.001) in weight between siblings in middle and ovarian or vaginal positions in the rabbit uterine horn in intrauterine growth retardation group after the 24th day of gestation.
