You have the anatomy backwards. Sperm enters the body in the vagina, then travels through the cervix to the uterus and (if they make it that far) to the oviduct (or fallopian tubes). So sperm would not travel FROM the oviduct TO the uterus because that would mean the sperm would need to start their journey at the wrong end of the anatomy.
Sperm travel by means of a whip-like tail called a flagellum. Under a microscope, sperm cells look like little tadpoles wiggling their flagellum to propel themselves forward. So, basically, they swim in the seminal and vaginal fluids.
uterus
Sperm transport results from uterine contractions. These contractions are stimulated by oxytocin released from the pituitary gland. Source: Clinical Anatomy and Physiology for Veterinary Technicians
Cilia lining moves the human egg through the oviduct. They beat in such a manner that it drives the egg toward the uterus.
At ovulation, the egg is released into the abdominal cavity near the funnel-like opening of the oviduct. Cilia on the epithelial lining of the duct help collect the egg by drawing fluid from the body cavity into the oviduct. Together with the wave-like contraction of the of oviduct, the cilia convey the egg down the duct to the uterus.
it's a site for fertilization. Ovum is carried along oviduct by beating action of cilia and contraction of muscular wall of oviduct.

A woman can only become pregnant if an ovum (egg cell) from her ovary is released into the oviduct and fertilised by a sperm there before moving down into the uterus and becoming implanted in the endometrium wall. If your oviducts are blocked, the ovum cannot travel into it and meet sperm so it can be fertilised so pregnancy is impossible.
the enter the oviduct
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).
uterus
Sperm, which is in the semen from a bull, goes from the bull's penis into the Fornix Vagina of the cow, which is located vagina close to the cervix. Sperm then travels through the maze of the cervix, and into the uterus. From the uterus, they travel up the uterine horns (or one of them) to the ovum or egg that has been released from the ovaries into the infundibulum down to the oviduct.
Fertilization, as in the fusing of sperm to the egg occurs in the upper uterine channels. After successful fertilization the egg travels to the uterus for gestation.
