It takes a few hours to reach it, and then about 20-30 minutes for a group of sperm to break down the outer membrane of the egg so one can fertilize it.
Barrier
They have it so when in a sexual intercourse (sex) they can sperm the girls egg!
The barrier method
if you are married you and your husband/wife give egg and sperm to a clinic, it gets implanted in another women, and she has your baby.
What is leaking from the vagina is not the 'cum' all together. the semen, or the liquid that protects the sperm from the women's natural defences, have no reason to remain in the vagina once the sperm have collected into a place called 'the sperm pool' which holds the sperm until the cervix or the small opening that leads to the uterus opens and allowd the sperm to move in and find the egg. Thus the semen is leaked back out of the vagina, since it is not needed in the body anymore.
When the sperm penetrate the egg cell fertilization occurs.
The shape of the sperm is a component needed in order for the sperm to penetrate the layers surrounding the egg. Each sperm needs a head, tail, and mid-piece.
The sperm structure containing enzymes to break down the egg's protective coating is called the Acrosome.
It can take 12 - 72 hours for human sperm to reach the egg.
It only takes sperm a few minutes to get inside of an egg.
If the sperm are not "healthy" or present in enough numbers they will will not have the ability to reach and female egg and then penetrate and fertilize then egg.
a sec
well in a way they all do (millions), that's what the sperms purpose is, its to go after the egg.
one sperm cell
It can take a matter of hours depending on how much sperm there is
When the sperm penetrates the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete, including whether it's a boy or girl. Creative Biogene
Acrosomes are seen in the anterior end of the sperm and this aids in the sperm to penetrate into the egg. Acrosome structure is formed by aggregation of lysosomal bodies and secretions of Golgi complex. These acidic components when released by the rupture of acrosome oozes out and this hydrolyses the egg membrane to facilitate the entry of sperm head into the egg for fertilization to take place.
