Sperm cells can get a girl pregnant. There is no such thing as a 'blank' sperm cell.
Human egg cells are produced in a baby girls ovaries. Sperm is produced in a boys testes. This happens while a baby is still in utero, while their mom is still pregnant with them.
If a human were to eat the same diet as a cow, then it will go through faster in a human than in a cow. Thus, a human on a vegetarian diet will digest food faster than a cow would on grass.
Sperm needs to go inside the vagina in order to get pregnant.
Animal sperm and human sperm do not mix, so it would be impossible for it to become a half bird, half human baby.
No, because the DNA structure of both species do not match.
Of course not. A female human can only get pregnant with a male human's sperm.
No Just like how human milk has no sperm in it
if there is human sperm in them?
Need human sperm.
No, it is absolutely impossible for a human to get pregnant from a dog.
Probably not, it comes from a human. But then, is milk vegetarian? It comes from a cow.
No. The human sperm is not compatible with any other species.
No they can't because they need the x and y sperm that we need. They do not have that type of sperm.
No. A pregnant cow is called pregnant cow or a bred cow.
