Maternal serum HCG (MSHCG) is higher when the fetus is a female than when it is male. This has been demonstrated in the second and third trimesters of pregnancy, and recently at 10-14 weeks gestation. In this study we assessed whether this gender-related difference can be detected as early as week 3 post-fertilization.
