What is ovulation?
Ovulation is the part of a woman's menstrual cycle that involves an egg being released from an ovary. Once the egg is released, it travels down the fallopian tube towards the womb. To become fertilised an egg needs to meet with sperm within 24 hours of being released. When this happens the fertilised egg is able to implant in the lining of the womb, where it will develop into an embryo. This process is known as conception.
