Yes, syphilis can cross the placenta from an infected mother to her fetus during pregnancy. This transmission can lead to congenital syphilis, which can cause serious health issues for the baby, including developmental delays, deformities, and stillbirth. Early detection and treatment of syphilis in pregnant women are crucial to prevent these complications. Regular prenatal screenings for sexually transmitted infections are recommended to ensure the health of both the mother and the baby.

IgG is the only antibody small enough to cross he placenta.
IgG is an immunoglobluin monomer, meaning that it is one immunoglobulin that is small enough to cross the placenta. An example would be the Rh antibody that causes isoimmunization between Rh negative mothers and Rh positive fetuses. In constrast, ABO blood group immunoglobulins are IgM which is a pentamer, meaning it is composed of 5 immunoglobulins and is too large to cross the placenta.
semen does not cross into the placenta and has no effect on baby in womb.
No. Red blood cells do not cross the placenta.
The embryo gets all the oxygen, and all the nutrients that it needs from the mother's blood supply, all of which crosses the placenta, through the umbilical cord into the embryonic blood system.
This is called natural passive immunity.
babies may be born with a drug dependency
Yes, alcohol can cross the placenta from the mother's bloodstream to the fetus. This can have harmful effects on the developing baby's growth and development, leading to a condition known as Fetal Alcohol Spectrum Disorder (FASD). It is important for pregnant women to avoid consuming alcohol to protect the health of their baby.
Congenital syphilis, caused by the bacterium Treponema pallidum, can lead to serious complications in the fetus, including blindness. If a pregnant woman is infected with syphilis and does not receive treatment, the infection can cross the placenta and affect the developing fetus, potentially resulting in ocular issues among other health problems. Additionally, other sexually transmitted infections like rubella can also cause vision impairment in newborns. Early diagnosis and treatment during pregnancy can significantly reduce these risks.
