Fertilization!
What an incredible adventure!
The path a sperm has to go through before fertilizating the egg is comparable to a fairy tale prince who has to climb different dungeons and kill various dragons before kissing his loved princess.
The complete journey of fertilization from the cellular perspective is epic, dangerous and a great adventure as explained in this great video of Thomas Brown of Nucleus Medical Media.
Well, hopefully my sperms like adventure! Actually they have already reached the holy grail once!
