Sex-differential placentation immunological interactions between male conceptus and gravida during normal pregnancy
Abstract:
7,773 placentae of newborns were analyzed in order to test a hypothesis of specific immunological concepto-maternal interactions due to maleness and occurring during normal pregnancy. An association between placental weight of newborn male and the sex of conceptuses of previous pregnancies was found which supports the hypothesis. No such an association was found for female newborn. The confirmation of these results could open new avenues in the study of sex-differential survival of the conceptus throughout gestation.

The Y Chromosome Determines Maleness
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
