well outside of the body not far at all unless you physically put them there, they will die after 12 hours for sure and you have to physically insert it into you to get pregnant so you can't get pregnant from a toilet seat or if some gets on your leg,
Fast-swimming sperm can reach the egg in a half an hour, while others may take days. The sperm can live up to 48-72 hours.
This depends on the species your investigating, the anatomy of the female, and the fitness of the sperm.

Yes, sperm can enter the uterus without fertilizing the egg. Just because a woman is fertile doesn't mean she will fall pregnant, there are a LOT of things that can go wrong to prevent pregnancy such as poor sperm quality or there not being enough sperm reaching the egg to fertilize it.
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)
In humans, the sperm cells must reach the female's fallopian tubes where the egg is located after ovulation.
Sperm have a long way to go and not very long to live so they pack light. They don't need ribosomes, roughER, Golgi apparatus, etc. They only need a sack filled with DNA, a flagellum, mitochondria to power it and a way to get into the egg if he's lucky enough to make it that far.
sperm cells are haploid and only contain half of the normal chromosomes (so when a sperm and egg fuse and form a zygote they contain a full set of chromosomes) and go through meiosis. normal cells are diploid (2n) and contain a full set of chromosomes and go through mitosis.
Sperm is the male sex cell that goes on to fertilize the egg in order for pregnancy to occur. The menstrual cycle is the female reproductive cycle, an egg is released during ovulation.
Sperm do not go up the wrong ovary. During fertilization, sperm typically swim through the cervix, uterus, and into the fallopian tubes where one of the ovaries releases an egg. The sperm then have the opportunity to fertilize the egg in the fallopian tube, not the ovary itself.

capacitation. Capacitation is a series of biochemical changes that sperm go through in the female reproductive tract. It involves removing certain coatings from the sperm head and increasing the sperm's ability to swim and penetrate the egg. Once capacitated, the sperm is able to fertilize the egg and initiate the process of conception.

The sperm doesn't have to. Once the egg is fertilized it stays fertilized.
To become pregnant, male sperm cells must fertilize a females egg. If a male and female have sexual intercourse at the right time when the woman is ovulating, sperm might reach an egg cell, few weeks later the woman skips a period, few weeks pregnancy test... go from there. Sometimes women have sperm put in their uterus if they don't want to have sex.
Normal sperm count is required for normal fertilization. Normal sperm count is between 60 to 120 million sperms per ml of the ejaculate. When the sperm count is below the 20 million sperms per ml, the chances of getting the pregnancy are very less. Although only one sperm can fertilize the ovum, many more indirectly help it to fertilize the ovum, by liberating the necessary enzymes.
Like any other animals....you have to breed a stallion and a mare.
A male will penetrate the females vagina with his penis, also known as sex. Once a male ejaculates sperm/semen into the females vagina, the sperm will go on a "hunt" for the females egg she releases during ovulation. Once the sperm find the egg, they will fertilize it. This egg turns into a fetus once it is implanted into the uterine wall. This is the traditional form of getting pregnant. There are now other forms of getting pregnant through the help of medical advances.
The excess sperm dies and it dissolves.
