In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells. There's a reason why egg cells, or oocytes, are so big: They need to accumulate enough nutrients to support a growing embryo after fertilization, plus mitochondria to power all of that growth.
Why is an egg bigger than a sperm?
An egg is about 30 times as wide as a sperm cell! ... Like a sperm cell, the egg contains a nucleus with half the number of chromosomes as other body cells. Unlike a sperm cell, the egg contains a lot of cytoplasm, the contents of the cell, which is why it is so big. The egg also does not have a tail.
