Growth and Development from Conception to the Final Stages.
Human life begins with conception. A fertile woman usually produces one egg cell each month, roughly two weeks after the last menstrual period. The egg cell travels from the ovary, along the fallopian tube towards the uterus. If sexual intercourse takes place while the egg is in the fallopian tube, then there is a possibility that a new life will be started. Millions of sperm are ejaculated by a man during orgasm. Just one sperm may fertilise the egg. Fertilisation means that the genetic material in the sperm joins with the genetic material in the egg to start a new life. Only about half of all fertilised eggs develop to become babies. Many eggs are lost without a woman knowing that fertilisation ever happened.
Pregnancy begins when a sperm penetrates an egg. One to one- and- a- half days after this single fertilised egg cell begins to divide. After two or three days there are enough new cells to make a fertilised egg the size of a pin head. This collection of cells travels to the lining of the uterus where it becomes anchored.
