when the sperm reached your egg...

If you have reached puberty the sperm is mature. Before puberty you have semen but no sperm. To see if the sperm is no good when it comes to impregnate someone that can only be seen in a microscope.
yes you can. It could still be in the cycle one or two more times even after the sperm has reached the egg.
A sperm don't need 70 days to to be able to fertilize an egg. Sperms are being made all the time and they are always ready to fertilize. When you ejaculate they are ready. So yes.
A sperm fused with an egg
sperm and egg. the sperm FERTILIZES the egg.
Gamates are know as the sperm and egg or "sex cells". These cells are the only cells in the body that undergo meiosis, not mitosis.
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)
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.
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.
