The human egg begins from the ovary where a sperm, through sexual reproduction, permeates the ovary's membrane. As the ovary contains this sperm, it dislodges and travels towards the fallopian tube. The fallopian tube serves as the duct that allows an implanted ovary towards the uterus where the egg can stay and mature into a fetus. A fetus that will then grow inside a placenta within the mother's womb for nine months.
