The egg will be fertilized
Sperm cell penetrates the ovum, and the egg is fertilized. The fertilized eggs are transported through the fallopian tube and now down in the uterine cavity, where it gets stuck. Some women get small bleedings from the vagina in connection with that the egg gets stuck in the lining of the uterus.
The child’s gender and genetic material found in the egg and sperm cell and therefore already at the time of fertilization is determined. By fertilization of the egg will be 23 chromosomes from the woman and 23 chromosomes from the man mixed, and this causes the fetal genetic basis.
When the egg from the ovary is loosened, it captured by the fallopian tube. The egg can live for up to 48 hours in the fallopian tube until it is destroyed, and it must therefore be fertilized within 48 hours after ovulation.
The man’s sperm (spermier) swims in large quantities (ca. 500 million) up through the cervix, through the uterus and into the fallopian tube where Fertilization of the egg the egg situated. happens roughly in the middle of the fallopian tube. Sperm can live for up to 5-6 days in the fallopian tube, and therefore the woman can become pregnant, even though she has had sexual intercourse a few days before ovulation.
The egg is surrounded by a shell, as the sperm trying to penetrate. As soon as that’s managed one sperm to penetrate the shell, it is impervious to all the other sperm. Sperm cell loses its tail, and head blends in with the egg nucleus. After fertilization, the egg can now share to multiple cells at the same time as it wanders further down the fallopian tube to the uterus cavity.
