I thought this is a myth?

Question

This is from the fermometer app. 🤔 
Sperm travels within seconds to reach the Fallopians and the  sperm that leaks out wouldint have made it through the cervix anyway🤷‍♀️

Answer

It is at least partly true, partly disproven by newer research, and partly true depending on a lot of things:
Sperm takes from 45 minutes to 12 hours to reach your fallopian tubes. There has been some research that showed that having an orgasm in the minute after ejaculation can increase the amount of sperm getting through the cervix, and speed up the movement. It looks like this is the number that the article quoted. This research has however been called into question in recent years.
Most of the guy’s sperm will actually never make it through your cervix when you are in your fertile week. A lot of his sperm is damaged, dead, or can’t swim straight. That is why healthy men produce so much sperm - to make sure that there is enough healthy sperm in his ejaculate. 
According to the WHO, a fertile male will ejaculate between 39 million and 259 million sperm. Typically between 40% and 81% will be alive (moving). Of those, about 32 to 75% will be able to swim forwards (as opposed to just shaking their tail or swimming in circles). Only 4 to 48% of his sperm will be well formed.
For a sperm to make it to the fallopian tube, it must be well formed and it must swim forwards. And in the cervix, things does not get better. It is a battle for his sperm to make it trough the fertile mucus in the cervix, through the uterus and up the fallopian tube, leaving many dead sperm along the way.
Something else that can affect the sperm’s ability to make it to the cervix is any lubricant you are using. When the guy’s sperm quality is in doubt, it is better to use a sperm friendly lube like PreSeef. Normal lubes are just one more fluid that the sperm must escape from to get to your cervix.
So YES, most of his sperm will die inside your vagina and be flushed out with the now liquified semen over the next 24 hours, leaving that wet spot on the bed or in your panties. This is called backflow.
Once he ejaculated, his semen is jelly-like. The heat and acidity of your vagina will liquify this semen over the next 30 minutes to release the healthy sperm in waves. After about 30 minutes, there are no healthy sperm left and very few will make it up your cervix after that.
This is where the advice comes from to lay still and maybe lift your behind for 30 minutes to give this process a chance to happen. However, once again, some real research showed that this only marginally improved sperm retention. For a healthy man and woman, it makes no difference.
When you are not in your fertile week, or you are on birth control, your cervical mucus are so dense that it does not allow many sperm to get through it. So almost all the sperm will be flushed out with the backflow over the next 24 hours.
So just to finish this description, it is true that it takes only one sperm to get you pregnant, but it takes many many millions of sperm to produce and get that one sperm to your egg at just the right time. 
Where you were born with all the eggs you are going to have in your ovaries (at puberty about 300,000 is left), a man produces about 1,500 new sperm every second (between 70 and 150 million a day)
Our bodies are truly amazing.
