We have studied the effect of gravity on the intrauterine fetus posture as the first step for investigating reproduction process of the human being in the space environment. In this experiment, we developed a method for measuring quantitatively the relation of movement of the mother to the posture of her fetus to estimate the effect of gravity on the fetus on the ground. As subjects we selected healthy pregnant 7 women and their fetuses in good condition, of 12-15 weeks along in their gestation period. We used an ultrasonic with which we can observe simultaneously movements of the fetus in three dimensions and a software for computing, with which we can analyze two dimensional movements, and established a method to demonstrate quantitatively a trend graph of change in posture of the fetus against the uterine wall axis of the mother. We found that effect of gravity on the fetus posture during table tilted, even though it dose not took much amount of angle change. It's suggested that the risk of torsion of the umbilical cord and tying the cord around fetus's neck may increase under the microgravity.
