Hormones associated with the menstrual cycle (period) cause eggs inside the ovaries to mature. Every 28 days or so, one mature egg is released from the ovary. This is called ovulation. After the egg is released, it moves into the fallopian tube where it stays for about 24 hours. If the egg is not fertilized during that time, the egg disintegrates (breaks down) and menstruation (your period) begins 2 weeks later.
Mature sperm cells are about 0.05 millimetres long, and are made up of a head, body and tail. The head contains the nucleus, which stores the genetic material from the 23 chromosomes in the cells of the male donor.
