Pregnancy is a miraculous process that happens when a sperm from a man’s body enters a woman’s body and fertilizes the egg. The fertilized egg will then develop into a fetus, and eventually a baby will be born nine months later. But how exactly does pregnancy happen?
The first step in the pregnancy process is ovulation, which occurs when an egg is released from a woman’s ovary. During this time, the egg travels down the fallopian tube, and is then ready to be fertilized by a sperm cell.
The sperm and egg will meet somewhere in the fallopian tube. Usually, only one sperm is able to penetrate the egg and fertilize it. The sperm pushes the egg’s outer layer open and deposits its genetic material, which merges with the egg’s genetic material, creating new cells with a mix of genetic information from both mother and father.
Once fertilization is complete, the egg begins to divide rapidly, forming a mass of cells known as the zygote. The zygote then makes its way down the fallopian tube and enters the uterus.
Within the uterus, the fertilized egg will attach itself to the wall of the uterus, and embed itself. This zygote grows into the fetus and nine months later a baby is born!
