How sperm got all the credit in the fertilization story

The school system probably failed you. Here’s how fertilization really happens.

Subscribe to our channel!

The fertilization story most of us know is skewed. In the textbooks we read in middle school and high school, it’s presented like a sort of fairytale: The strong sperm go on a journey where they have to defeat and overcome obstacles to reach the egg. Meanwhile, the egg just sits around waiting to be fertilized.

The story inherently carries a lot of gender bias, and what’s worse is that it’s not entirely true. The sperm can’t make the journey on its own, and the real story of fertilization involves two reproductive systems working together. While sperm have tails that seem like they’re meant for swimming, they can’t propel themselves all the way to the egg - they need the female reproductive tract to help move them forward. And the egg doesn’t just wait around for the sperm to reach it - it has an active role in selecting which sperm will be the best one to fertilize it.

So why has the fertilization story been skewed in this gender-biased way? We dig into a study of textbooks from middle school to medical school to find out.

Read the original studies here:

that is a "problematic message"? this really seems to be research for the sakes of getting offended. Its not adressing any present problems. Instead, its trying to find something that you can call problematic. what a farce

LoL. Americans care more about if egg is important in fertility. Instead caring that you cannot afford birth in US hospitals..

I guarantee you even check those books it shows it teaches you it all too; they're literally just making things up; gaslighting to be "offended" at an issue that doesn't exist nor has ever existed. They're at the point where they just have to make things up to protest.

Politics and education or should we say vetted education by Texas standards is this the norm? If so published textbooks need a deep review of materials or we all remain ignorant together. Powerful educational boards dictating input policies need to be held to honest equitable and scrupulous reviews when establishing fair guidelines that proclaim truths as we know them to be.

It's not; don't base what anyone is taught in America on this video; Vox is literally just making this up. I grew up in a small town conservative area and even we learned all this stuff back in middle school. If anyone in this video truly didn't know it, it was because they were probably too busy zoning out because "science is like hard and boring."

While I agree with vox on their intentions, I think they really missed the mark with rhetoric here. Start with the science, then dive into sociology and history, and then explain why all this is important. This weird mashup is sloppy.

Teviman 24 दिन पहले
Half of the truth isn't the truth. Textbooks are written by mere human beings, all the so called "facts" in there aren't always absolute. Especially since human perspective changes over different time periods, and as you can see most of the men they had there are people in the past, when the society were still pretty much sexist.
