Sperm cells are following a rhythm much like those patterns in magnetic fields to propel themselves into the fallopian tube and subsequently to the egg. According to study author Dr. Hermes Gadelha, these rhythmical patterns are precise and systematic head and tail movements. Sperms don't randomly "wiggle" but the apparently calculated their move towards a singular aim - get into the egg first out of 55 million other sperms.
Scientists know that there should be certain conditions required in order to guarantee conception. First is the capability of the sperm cells to "stay alive" in the women's vagina and cervix. In this cyclic hormonal control condition, the cervix must admit the sperm without damaging them. Lastly, sperms should possess the quality to convert themselves into a form that can penetrate the egg, according to the University of California, San Francisco.
However, these processes lack the explanation about how the sperm cells can travel through the fallopian tube itself. Their journey is a strenuous one from the beginning since they have to survive the acidic nature of the vagina in the first place. Scientists know that sperms are coated with seminal plasma when they are still in the vagina and leave this gel-like coating when they enter the uterus.
The University Hospital Southampton said that sperm cells need to "swim" their way through a long journey to the fallopian tube. Consider these microscopic would-be babies as very much like an athlete who needs to swim several kilometers. However, the fastest sperm can locate the egg in as fast as 45 minutes, a rate of about 2.5cm in every 15-minute duration.
So again, what makes them excellent swimmers? Dr. Gadelha thinks that at least we understand human conception much better now, proving that sperm cells
have "intelligence" from the very moment of male ejaculation. It is prudent for people to know the earliest stages of conception because, after all, that is where we all came from.
