OVULATION is when a mature egg is released from the ovary. Approximately every month an egg will mature within one of ovaries. As it reaches maturity, the egg is released by the ovary where it enters the fallopian tube in order to be fertilized. If fertilization occurs, egg will attach to uterine wall.

  • Normally one egg is released each time of ovulation
  • Ovulation can be affected by stress, illness or disruption of normal routines
  • Implantation of a fertilized egg normally takes place 6-12 days after ovulation
  • Woman is born with millions of immature eggs that are awaiting ovulation
