If a fertilized egg remains in the oviduct instead of implanting in the uterus, it can result in an ectopic pregnancy. In this case, the embryo may develop in the oviduct, which is not designed to support a growing pregnancy. This can lead to serious complications, including rupture of the oviduct, internal bleeding, and potential harm to the mother's health. Ectopic pregnancies typically require medical intervention to prevent these risks.

A fertilized egg develops in the uterus after it leaves the oviduct. It implants into the uterine wall where it continues to grow and develop into an embryo.
Oviduct is where the egg cells are fertilized while the ovary is where the egg cells are produced and where they mature.
There is no size requirements, the egg is fertilized inside the hen before the shell surrounds it on its way through the oviduct.
As it passes through the oviduct, the egg is fertilized by sperm if present. It also undergoes various physiological changes, such as the formation of the eggshell and the addition of protective layers. Finally, the egg is released from the oviduct and deposited for external development.
Yes, the egg travels through the oviduct in the female reproductive system. The oviduct is where fertilization typically occurs if sperm are present, and it serves as a pathway for the egg to travel from the ovary to the uterus or be released from the body during ovulation if not fertilized.
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.
The oviduct in chickens plays a crucial role in the reproduction process. It is responsible for the transport of the ovum (egg yolk) from the ovary to the uterus, where it is eventually formed into an egg. The oviduct also facilitates the addition of egg white (albumen), membranes, and the shell as the egg passes through its various sections. Overall, the oviduct is essential for the development and formation of fertilized or unfertilized eggs in chickens.
A chicken egg is fertilized when a rooster mates with a hen, transferring sperm to the hen's oviduct where the egg is formed. The sperm fertilizes the ovum (egg cell) within the oviduct, resulting in the formation of a zygote. The zygote then develops into an embryo within the egg as it travels down the oviduct and is eventually laid by the hen.
After traveling through the oviduct, eggs are typically released into the uterus, where they may be fertilized if sperm are present. In birds, the egg is then encapsulated in layers of albumen, membranes, and a hard shell before being laid. In mammals, if fertilization occurs, the egg implants in the uterine lining to develop into an embryo. If not fertilized, the egg is eventually expelled from the body.
The oviduct, or fallopian tube, is specialized for its role in reproduction. Its inner lining is equipped with ciliated epithelial cells that help transport the egg from the ovary to the uterus. Additionally, the oviduct has a muscular wall that facilitates peristaltic movements, aiding in the movement of both the egg and sperm. The environment within the oviduct also provides nourishment and support for the fertilized egg during the early stages of development.
In humans, eggs are typically fertilized in the Fallopian tube. The fertilized egg begins to divide and continues down the tube and implants in the uterine lining. If it implants in the Fallopian tube, this is known as an ectopic pregnancy (bad). In a chicken also, the egg is fertilized in the first part of the hens oviduct.
