If the sperm do not find the egg they die off in about 5-7 days depending on how hostile the reproductive tract of the women and are absorbed by the womens body or disposed of just like a period or discharge.
the sperm just die
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?"
An egg only allows one sperm to enter and is fertilized by that one sperm: 2 cannot enter.
because the sperm cells fail to find the egg cells or the sperm isn't good to unite with the egg
There are millions of sperm and they search everywhere for an egg. The sperm will die unless they fertelize an egg. So any way they will die.

The sperm from the male has to meet with the egg from the female
The egg is broken into pieces (disintegrates) and is discharged as menstrual flow
The fact that only one sperm can fertilize an egg. After the sperm enters the cytoplasm of the oocyte, the cortical reaction takes place, preventing other sperm from fertilizing the same egg
More than one sperm will not enter the egg.
If sperm does not enter the vagina, there is no chance of pregnancy. Pregnancy occurs when sperm fertilizes an egg, and this can only happen if the sperm comes into contact with the vagina and eventually reaches the egg in the fallopian tubes. Without this contact, pregnancy cannot occur.
Fertilization occurs when a sperm cell and an ovum fuse, resulting in a fertilized egg.
