This video explains everything about human sperm like
- the movement of sperm inside the female reproductive tract
- the misconception of the movement of sperms, how sperms cheated every scientist with its movement
- sperms journey from human body to female egg
- how eggs select the sperms
There was a belief earlier that human sperm travels like a snake in a swirling path, but recent discoveries have found that it is not exactly right. The sperm travels by rotating its whole body from head to tail, this rotation gives an upward movement to the sperm helping in its journey to the egg.

Another misconception that the first joint egg develops into a human is also proved to be wrong. It is recently found that there is a chemical named Chemoattractants that release a chemical. This chemical attracts the sperm and shows the way to the egg. Not only one, but many sperms reach the egg at the same time. The egg later detects the egg with the rich DNA and puts it into it.

This video also explains why some couples couldn't get fertilized even though they have no problems in their body. The reason is, eggs tend to choose sperms only from certain males, if the sperms from any different male enter the cervix, the egg refuses to choose it, hence that particular couple couldn't get fertilized.

Why Testicles are present outside the male body - the reason is temperature. The sperms need to maintain a less temperature (2.5 to 3 degrees) than the temperature of the average human body. If suppose it was present inside human body, whenever we get fever or comes under high temperature, sperm count would have become less.
