title: [Levels of testosterone-estradiol-binding globulin TeBG and of testosterone in pregnancy with relation to the sex of the foetus (author's transl)].
abstract: A practical and economic method for the quantification of testosterone-estradiol-binding globulin TeBG is described. The procedure premits the differentiation without overlap of the TeBP levels in males, non-pregnant females and during pregnancy. Mean titles were 1/5, 1/93 and 1/360 respectively. During pregnancy, we found high levels of TeBG and increased plasma testosterone, with mean values of 143.4 nanograms/100 ml. We have found no significant differences in TeBG levels, or in maternal blood testosterone levels in relation to fetal sex; however, plasma testosterone levels were significantly different among new born of different sex, with mean values of 96.25 nanograms per cent for males and 78.21 nanograms per cent for females.
