Which structure is responsible for the fertilization of the egg?

The oviduct is the structure responsible for the fertilization of the egg. It serves as the pathway for the egg to travel from the ovary to the uterus. After ovulation, an egg is released from the ovary and enters the oviduct, where it may encounter sperm. Fertilization typically occurs in the oviduct, as it is where the sperm meets the egg. The environment of the oviduct is favorable for this critical process, providing the necessary conditions for the sperm to fertilize the egg. Once fertilization occurs, the resulting zygote moves further down the oviduct toward the uterus for implantation.
