I don't know what goes on beyond the cervix

nebi · Answer

Male sperm swim through the vagina, through the cervix, into the uterus, then the sperm split through the fallopian tubes, and meet the female egg.

The female oocyte can only be fertilized in a short time window when matured, ejected from the ovary after ovulation. The oocyte normally has an impermeable membrane, but when a spermatozoid reaches it, it interacts with the membrane and signals its presence so that the oocyte allows it just enough time to enter. this window is so short that only one nucleus can enter it. Any sperm cells that reach it later will not be able to enter it.
The hapliod (single set of 23 chromosomes) core of the sperm cell fuses with the haploid core of the oocyte, creating the very first diploid cell that starts dividing and will eventually be the root of all cells forming a fetus. This is usually the moment that's considered fertilization.
