When people think about how babies are made, what usually comes into their mind is that man and woman meet, they make love and after nine months, a baby pops out. But are you exactly aware where the eggs and sperm are coming from or how do they find each other and combine creating a new life?
For women, the possibility of getting pregnant starts in the ovaries. These are two tiny oval organs that are fixated to any side of the uterus. The ovaries are filled with eggs that are made right before the baby is born. Baby girls are born with one to two million in the ovaries of the mother. Most eggs start to try off almost immediately and the rest decrease steadily in number as the person gets older. There are about 400 eggs released in the fertile years between the first period and menopause.
In every menstrual cycle, sometimes after the period, one or two eggs are starting to get to maturity in any of the ovaries. The ripest egg will be released and this process is called ovulation. The egg is sucked up quickly by the tulip-shape opening of the fallopian tube that is the nearest. Ovulation is usually around 12 to 14 days before the next period. The exact ovulation time will depend on the length of the cycle. Various hormones are working together to control the cycle length when the eggs ripen and timing of ovulation. The average egg will live for up to 24 hours after it is released. At this time, it has to be fertilized by a sperm in order for the baby to be conceived.
If the egg has met the healthy sperm on the way into the uterus, the process of creating a new life will start. If not, then the egg will end its journey at the uterus and then disintegrate. If the woman has not conceived, the ovary will stop making estrogen and progesterone. These are the two hormones which would help in maintaining a pregnancy. When the hormone levels drop, the coagulated lining of the uterus is shed during the period. The remains of unfertilized egg are shade as well as the same time.
