Once inside of the fallopian tube, an egg cell has about 48 hours to live. If it is not fertilized by a sperm within this time, it will die. The follicle that released the egg is now called a corpus luteum, and it will secrete a hormone called progesterone for about two weeks after ...

the cells and helps to control the speed at which they move. The energy required for the whiplike or flagellar motion with which the tail propels each sperm cell through the seminal fluid is provided by small cellular structures called mitochondria which surround the upper portion of the tail....
The structure of these cells includes a head that contains enzymes designed to help the cell penetrate the egg. While the human egg is very small, male gametes are even smaller, and the outer wall of the egg is essentially an impenetrable wall without enzymes to help the cells wriggle their...
