I watched the video called Life's Greatest Miracle. This video shows how a baby is created. It starts showing since the sperm goes inside the vagina. Also, goes in deep detail about how an embryo is developed step by step. It says that our body want to make babies. Everyday there are 365,000 babies born worldwide. The most interesting fact is how incredible is for a woman to create life. It is also interesting how the DNA is responsible for reproduction. It explains all the cells, molecules, tissues that create organs which allow a life to be created. I am surprised that it takes so much work for our body to create a life, and we do not notice all the work that is going on inside our body while we are doing activities. Many people say that is so easy to get pregnant, and many women keep getting pregnant right after one and another. However, this video shows how much work sperms have to do in order to get to their destination. There are millions of sperms that travel to meet their egg, and only one or two make it because the 60% of the sperms die in their journey. This is because the vagina is acid, therefore, the acid kills the sperms. In this case, sperms are more about quantity instead quality, and the eggs are more about quality instead quantity. Then, it talks about every step in the journey of the new life’s development . You must watch this video because it is informative and super interesting. Over all, I was surprise to find out that men are responsible for the baby’s gender.
