The majority of patients undergoing IVF treatment are unable to conceive because of blocked fallopian tubes, pelvic adhesions, ovulation disorders and other factors that prevent the egg and sperm from meeting, while the first generation of IVF technology is to remove the patient’s egg and sperm and make them meet, know and love each other naturally outside the body, and eventually blossom and bear fruit to fulfill the patient’s dream of becoming a parent. So, what kind of fantasy journey do the sperm and eggs go through after they leave the body? First of all, we start from the moment the eggs are removed, our doctor will aspirate the eggs through a very thin hollow puncture needle, guided by ultrasound, through the posterior fornix of the vagina, We have to let them rest for a while in an incubator with a specific temperature, humidity and carbon dioxide concentration, and then arrange to meet with those elegant “sperm dudes”, which usually takes about 3 hours. And in the process of “ladies” grooming and grooming, the cruel selection of those handsome men has just begun, after the semen left, we must first pass the initial screening, eliminating the old and sick, and then the second round of players will be placed in the bottom of the lake made of special culture fluid, the gun will be fired, everyone will The race lasts about 30 minutes, and because it is an audition, the final sperm left to meet with each of our egg girls is around 30,000. The next stage was the most thrilling final stage, where our egg girls were placed in the middle of a specific petri dish, and the 30,000 sperm were spread out in a circle around them, and when they were instructed to start the race, they all sprinted forward as if they were arrows. Finally, a prince charming is the first to stand in front of the egg, and his sincerity impresses her so much that she builds a wall of love for the prince and does not accept any more confessions from other handsome men. The long run of love between the sperm and the egg finally comes to an end, next they will be put into the womb at 72 hours of union and a brand new life is born from there! Of course, in the final process, some of the eggs will be duplicitous and accept the courtship of two or even more sperm at the same time, then such a union will eventually be abandoned. There are also some girls who are too discerning and don’t see a single young man, which results in what we usually call a failed fertilization.
