Of course not. A female human can only get pregnant with a male human's sperm.
Human sperm move through the female reproductive system by swimming using their tail (flagellum). They are guided by chemical signals released by the egg and the female reproductive tract, which help them to navigate towards the egg for fertilization.
DNA always remains in the sperm, that is how variation happens.
Fertilization is when a sperm cell and egg cell fused together to develop an embryo. So it happens within the 24 hours after the egg is released. That can be around the second week of the cycle.
