Women don't have sperm.. so that is not possible.
By having your dick going to a girls vagina and you go on top of each other and move your dick up and down
It's determined by the genetic chromosome of the sperm. Women have only one X chromosome in the egg (both egg and sperm have 23 pairs of chromosomes, which unite to form 46). On the other hand, men have either X or Y chromosomes. If an egg (X chromosome) joins with an X chromosome sperm, the result will be a girl. If an egg (X chromosome) joins with a Y chromosome sperm, the result will be a boy. In other words: the guy determines the sex of a baby :)
Nothing. A woman who is already pregnant can not become pregnant again before the current pregnancy resolves.
Sperm form the male ejacualtion carries important genetic information that supplys the egg with the information needed from the father of the baby. It carries the genes from the father, things like; what colour hair the baby will develop, the colour of its eyes and its personality charactersitics and etc. Each sperm has its own set of unique charactersitics and genes from the father. The characrteristics from the sperm (the father) and the charactersitcs from the egg (the mother) combine to create the fetus.
Generally, one sperm cell and one egg cell unite for each offpring that is created (some cases, such as monozygotic/idential twins, are different). This means that if a human has one baby, it was one sperm and one egg. Or if a dog has 5 puppies, it was 5 egg cells and 5 sperm cells that united.
The babies sex is determined by the sperm. The egg has XX chromosome and each sperm cell is either a XX or XY chromosome. So which ever sperm cell reaches the egg and implants determines the sex. If the sperm was an XX chromosome the baby would be a girl, if the sperm was XY chromosome the baby will be a boy. Hope this helps!
Not simply using each other's cells, but with some sperm, lesbians can (and do!) have children!
Well, they need a guy in there somewhere. Pregnancy can't happen without sperm.
women carry eggs, men carry sperm. Each month when the womens egg isn't fertilized by the sperm, you shred the egg and the lining protecting the egg.
Girls can be friends. But girls shouldn't date each other. I think it's wrong.Another answer:It is fine if that is what seems to draw you but expect others not to understand.
Each Egg and each Sperm contain only half of the genetic material to make a new animal (a baby). Thus if they do not join then the two parts of the genetic material can never come together.
Two ways- Sometimes the mother releases two eggs instead of one. Each egg would be fertilized by a different sperm cell, and would grow into two different babies- known as fraternal or non-identical twins. The second way is one egg, fertilized by one sperm- but as the egg begins to grow, it divides in two, each of which will become a baby- and they are identical to each other (they started life as the same being).
Six
The genetic makings for the baby are in each. The male contributes sperm; the female contributes an egg. After the egg is fertilized by a single sperm, the embryo implants itself in the womb of the female and eventually grows into a fetus, which will be a baby once born. Both genders must contribute for an egg to become fertilized, but only the female carries the baby to term (birth).
If it is a boy the bottom of its shell will be concaved and if it is a girl it will be flat.

No seperate them most likely they will kill each other or each others babies.
