Have you ever wondered of the life of a sperm? It is a remarkable and amazing life? I am a sperm, and let me take you through my life. I live in the testes and I’ve lived there my entire life, from birth to currently. Some of my family have already left the house and gone on to explore the outside world. Us sperm have one goal in life and one goal only: to reach the egg. The egg is where all sperm dare to go and tries to fertilize the egg. Millions of our kind attempts this, but in the end, only one of us will be the one to fertilize the egg.
There were many scientists who had a variety of hypotheses for the purpose and functions of me. They just don’t realize that the only one knows me better is myself. For example, Anton Leeuwenhoek wrote that I was like seeds and eggs just provided nutrients like soil where the seeds were planted. Others regarded me as insignificant and that a human could perfectly well be fertilized without the prescience of me. Lazzaro Spallanzani in the late 1700s believed that I was like a parasite. How rude! He doesn’t know how important we are. He also concluded that filtered toad semen without me would not be able to fertilize an egg. However, he thought that I wasn’t the reason for fertilization, but that it was the toilet paper. However, in 1824, J.L. Prevost and J.B. Dumas claimed the right hypothesis. Finally, someone has got it right. I was beginning to feel like these scientists weren’t giving me enough credit! After all, where would they be without me? Anyways, he correctly confirmed that I was not a parasite, but that I was the active agent of fertilization and that I am universally present in sexually mature males. Another interesting claim was from Oscar Hertwig, who believed that there was no physical contact between the egg and myself. He also observed that only one sperm reached the egg. Us sperm always dream of reaching the egg, and there’s some fierce competition. My family is revered, and
