It's pretty bonkers when you think just how far modern medicine has come in the last 100 years, particularly when it comes to childbirth. Think about it: 100 years ago, women didn't even have a test they could take to let them know they were pregnant — they had to figure it out based on the changes in their body alone. Now, we have pregnancy test, ultrasounds, and all manner of technologies to get us through the childbirth process –and apparently, you can even choose the sex of your baby.
Admittedly, they haven't gotten sex-choice down to a science. Instead, it's most about understanding your sperm and tracking your cycle, allowing for intercourse at the exact right time. Learn more about what it takes to potentially control the sex of your baby below — and how the difference of characteristics between male and female sperm can potentially decide whether or not you're choosing blue or pink.
What if you could choose the sex of your baby?
People say they don’t care, but many would secretly prefer a girl or a boy. Until now, you had to leave it up to chance.
Dr. Shettles is an expert with 50 years of experience in in-vitro fertilization, or IVF.
He wrote a book called How to Choose the Sex of Your Baby, where he gives instructions on how to get the gender you prefer.
It's all about the chromosomes.
To have a boy, you need a sperm with the ‘Y’ chromosome, versus the “X’ chromosome, which are female. Two X chromosomes will give you a girl.
Y chromosome sperm tend to swim faster.
However, X sperm are heartier and larger, but swim slower. In other words, it could really be anyone’s game.
But as it turns out, the speed of the sperm can make all the difference — depending on when you ovulate.
If the egg is already in the fallopian tube, the faster Y swimmers sperm will get there first and result in an XY fertilization. Odds are, you’ll have a boy.
