title: [Maternal serum levels of chorionic gonadotropin and its alpha and beta free subunits as a function of the fetal sex. Preliminary study].
abstract: The maternal serum levels of hCG and its alpha or beta subunits were measured in 96 normal pregnancies and correlated with the fetal sex. During the first 20 weeks (69 cases), the maternal serum levels of hCG, of its alpha subunit and particularly of its beta subunit were higher in cases of female fetuses. However no statistically significant difference was observed between the levels of hCG or its subunits in serum of pregnancies with male or female fetuses. During the second half of pregnancy, the serum hCG levels were discretely higher in cases with female fetuses (no significant difference) and the serum levels of its alpha or beta subunits were identical in cases of male of female fetuses.
