Fetus Feedback to Mother
Country: United Kingdom
Date: Spring 2013
What does the fetus give to the mother through blood?
Thanks for the question. The fetus contains half of the genes of the father. Thus, the fetus may transmit antigens to the mother and perhaps other small molecules such as hormones. The transmission of antigens from the fetus to the mother may result in sensitization of the mother. This process may occur in erythroblastosis featalis.
I hope this helps. Please let me know if you have more questions.
