Abstract

Ultrasonographic localization of the placental site was performed serially throughout pregnancy in 56 primigravidas with anteriorly located placentas. The placenta was found to be located on the right side of the uterus significantly more frequently than at any other site on the anterior uterine wall. Placental position was found to be related to the position of the fetus in utero. The role of placental location in determining the high incidence of the left occiput position at delivery is discussed.

    Citation Excerpt :

    The factors that determine the site of nidation of human blastocyst are not fully understood. Human blastocyst normally implants in the upper portion of the uterus and then placentation begins [8]: anterior, posterior, fundal, right or left sides of uterus are all normal places for placental development [9,10]. When placenta is attached lower down in uterus it is known as placenta previa, a situation which carries an increased risk of hemorrhage.
