the sperm reaches the uterus through the cervical opening or cervical os.
The barrier method
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.
That would be very, very unlikely.
No. Only men produce sperm.
Not without killing the sperm too.
It takes about 3 days for the sperm to reach the egg and fertilize it in the fallopian tube and than another week for it travel to the uterus and get attached to the uterus wall.
No?
Because the egg cell is carried down the oviduct by little hairs called cilia and the sperm cell has to reach the egg cell before it gets to the uterus (womb).
Into her uterus.

A man doesn't have a Uterus.
Nope - the natural fluids present in the uterus kills off the sperm after a few days.
