When these components combine, they create a new being, but the process to get to this point is quite amazing. The Sperm and the Egg The process of conception can sometimes be difficult to understand because a lot more happens than two people having sex and conceiving a baby. In fact for one lucky sperm, it is an incredible journey of competition and resiliency. Each sperm and egg is competing against roughly 500 million others, which makes the meeting of the final two an amazing accomplishment.

Stan the sperm starts his life in the testes, which sit inside the scrotal sac. Inside the testes, he resides in the seminiferous tubules. This is where he begins life while growing and maturing for roughly two months. From here he relocates to the epididymis where he waits before being shot through the urethra. When he enters the urethra, he is now located in a canal inside of the penis. Inside the urethra of the penis, he is combined with secretions of the prostate gland, which guide him on his voyage towards Eva the egg. First, Stan and the secretions from the prostate gland are discharged with incredible pressure through contractions created by pelvic muscles, known as ejaculation. The seminal vesicles produce a sugary fluid which follows Stan and the secretions. This is the final time that Stan will be inside of the male body because he is exiting the penis and entering the vagina, which is where the fertilization will begin. The female body has to do her part to allow fertilization to occur. From the beginning, Eva has roughly a one in 500 million chance of being fertilized. Now, Eva is a very desirable object and she is surrounded by millions of cells that provide protection as well as nourishment for her voyage. While this is happening, the fallopian tubes have been given the go ahead to capture Eva. Projectors inside the fallopian tubes were able to retrieve Eva, whom is still accompanied by thousands of nutritious cells. Inside the fallopian tubes, Eva is safe and she will remain here until she has prepared herself for her meeting with Stan. Fertilization will occur inside the fallopian tubes. At the furthest end of the vagina, the cervix, Stan the sperm has been shot against the opening through ejaculation. Stan will travel several inches towards the fallopian tube, but this journey could take several hours. During his journey, Stan the sperm begins to change due to substances in the cervix, uterus and the fallopian tubes. Stan is now capable of fertilizing Eva the egg. Eva has undergone ovulation and is waiting for Stan to arrive. Stan the sperm is deemed alpha and has reached a level of dominance which makes his journey much shorter than others. This process can take anywhere from several minutes to a few hours, but like I said, Stan is much more dominant than others and carries a lot of energy called mitochondria. The mitochondrion pushes him toward Eva along with several hundred others. Eva the egg begins to rotate from the drilling and tail beating of Stan and the others. Eva is still surrounded by nutritious cells so it essential that Stan battles through them. Stan releases enzymes when his acrosome disappears. These enzymes allow him to break Eva’s wall down so that he can enter through. At this point, many of Stan’s competitors have fallen short of their goal and are no longer able to battle. Several sperm are able to attempting to break through Eva’s wall, but Stan again is the dominant sperm and is able to penetrate her inner cell plasma. When this happens, Eva shuts down and does not allow any of the other competitors to enter her, no matter how close they were to penetrating. Stan has made it farther than any of the other 500 million sperm that set out with the same goal. After a long journey Stan the sperm and Eva the egg unite. However, Stan still has some work to do until breaks through to Eva’s inner cell. In a drill like manor, Stan uses his tail to rotate himself. Stan now has penetrated his head through the ovum wall and is on his way to the interior membrane of the cell. Stan’s head has busted through Eva’s plasma. He is also on his way his way to the Eva’s nucleus which stores her genetic material. Next, the fusion of their nuclei occurs which instantly form hereditary characteristics of the new being. This has completed the journey of Stan the sperm to Eva the egg and results in conception of a new individual.
