No, not at all. The males provide the females with their sperm so that the females can have fertilized eggs. After that, the females hand all their eggs over to the males for safekeeping. So the male is not pregnant, but holds all the eggs, and appears to be pregnant.
If the male's sperm comes in contact with the females vagina, the female can get pregnant.
