—Sperm meet the egg in one of the fallopian tubes, but how do they know which one? Well, we're not entirely sure yet, but it looks like sperm swim towards the fallopian tubes because they're warmer than the uterus, and the egg uses chemicals (chemo-attractants) to attract sperm.

The egg is basically surrounded by a shell of protein fibers. This makes it nearly impossible to be penetrated by anything EXCEPT sperm. Sperm are (metaphorically) a 350 horsepower engine of a rowboat full of treasure. They are all engine and little payload. However they have three things going for them besides the engine. Obviously there is the father's DNA. There is also a lot of energy (sugar) to make everything go. Finally there is the secret weapon: a bunch of protein eating enzymes on the very tip. Effectively when the sperm hits the egg its tip begins to eat away at the shell. At the same time it's engine just keeps on going driving the sperm further and further in. The combinations of this eat a little, move a little strategy will worm its way into the shell. Once the shell is breached two things happen. The sperm will lose all of its ability to use its energy (the mitochondria all die out) and so it just gives up the DNA payload. Also the egg undergoes a chemical reaction to stop any additional sperm from getting in. So it litterally is first come, first served.

Find out how sperm and egg cells meet in cod?
The egg would do external fertilisation, so the female would let the egg out, and then the male would spray the sperm over it, and then the two would have a baby.
What will happen when sperm cells find their way into the female reproductive system?
you've got to be kidding me. Sperm swim up until they find an egg, the fastest one there gets to fuse with the egg, become an embryo, and make a fetus. To quote a movie: "10,00 sperm and you were the fastest?"
How does the sperm get in to the egg?
To get to the egg the sperm has to first go through sexual intercourse and then the sperm travels in a liquid till it reaches the fallopian tube where the egg is to get into the egg the sperm uses its tail. (only a brief way)
How do you know if you have a girl or a boy?
It depends on women's egg. Women have a egg which is a child. Peroids are eggs, eggs can die if not fertilized, periods drain the egg away. Women grow a egg each month. The egg needs sperm to fertilize to grow into a child. The men's penus touches the women's vagina and the sperm swims into the women's body to find a egg. Only one sperm can get into the egg. The men's sperm decides what gender the baby is. Women's eggs is x. Men's sperm is y and x. If egg x and sperm y touch, it's a boy, if egg x and sperm x touch, it's a girl. If a sperm gets into a egg and the egg breaks in half, it's twins with same gender. If a egg breaks in half before a sperm gets in, then two sperms can get into the two half eggs and thay'll have a different gender, but still twins. So there it is. Please thank me for I'm a guest.
Why egg cell is larger than sperm cell?
The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.
