[The surface of the syncytiotrophoblast in the human placenta at term in relation to the sex of the neonate].
A stereological analysis was performed on 30 human term placentas. Surface density and total surface of the whole syncytiotrophoblast and its specially differentiated parts (alpha and beta zones, syncytial knots) were measured with regard to the sex of the newborn. The values of stereological variables are higher in placentas of female newborn children, but differences are not statistically significant. The placental index was defined by macroscopic measuring of the weight of fetus and placenta. It was considerably higher in male (7.92 +/- 0.27) than in female (7.15 +/- 0.18) newborn children, P less than 0.025.
