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.

Function of the oviduct?
The oviduct is a tube that serves to transport the egg from the ovary to the uterus. Fertilization usually occurs within the oviduct, and it also provides a suitable environment for early embryonic development. Additionally, the oviduct helps in the transportation of the embryo towards the uterus for implantation.
What is the job of the oviduct?
The oviduct, also known as the fallopian tube, serves as the passageway for eggs to travel from the ovaries to the uterus. It is where fertilization of the egg by sperm typically occurs and is an essential part of the reproductive process in females.
In a frog what tube allows egg to come out of the cloaca?
In a frog, the oviduct is the tube that allows eggs to come out of the cloaca. The cloaca is a common opening for the reproductive, digestive, and urinary systems in amphibians, and the oviduct is responsible for transporting eggs from the ovary to the external environment through the cloaca.
When sperm reach the oviduct there is no egg what happens to the sperm?
If there is no egg present in the oviduct when the sperm arrive, the sperm will typically die off and be naturally cleared from the body. They have a limited lifespan and cannot survive for long periods within the female reproductive system without encountering an egg for fertilization.
Is the hen egg fertilized after the shell formation?
No. The egg yolk is fertilized before the yolk and albumin are joined and well before the shell is formed. The oocyte (yolk) is produced during ovulation. This is released into the oviduct where it is fertilized by a sperm from the sperm sac previously deposited by the rooster. The yolk continues down the oviduct fertile or not and is surrounded the vitaline membrane, then by albumin and then shell membrane and finally the calcite that hardens into the actual shell. This takes about 24 hours.
