Résumé : | [BDSP. Notice produite par INIST 7nLisR0x. Diffusion soumise à autorisation]. The decline In the male/female ratio of births has not yet been explained. In Japan, the male/female ratio of fetal deaths has been Increasing since the 1970s, reaching over 2.0 In 1996. The Increased male/female ratio of births could explain the decrease In the male/female ratio of births during the past two decades. This trend could suggest the Increasing prenatal vulnerability of the male fetus especially at earlier stages of gestation. |
