Quoted By:
1 - Samus suit protects from radiation influence.
2 - Though she does contain Chozo DNA, her body is still very human compatible. The DNA is kinda like safe steroids.
3 - The Metroid DNA did alter her, but to the extent of a vaccine. The only draw back is that she can not stand a temp that is too cold.
The X parasite goes inside her to try to take over her DNA, but since she is now immune and her white blood cells now stronger with metroid-vaccine..the parasite just gets broken down for sustenance.
IN SHORT:
She can still have sex with a dude and have a baby. She doesn't since she feels like that would be putting her new in danger since she is pretty much wanted by pirates and other enemies or corps. that view her as a threat.
