Q&A: How is my baby's gender determined?

How is my baby's gender determined?

Re: How is my baby's gender determined?

The Bump Expert

The sex of a baby is determined by two sex chromosomes inherited from both the genetic parents. A baby will normally inherit one sex chromosome from the mother and one from the father. A woman has two X chromosomes and thus gives either of her X chromosomes. The father has one X chromosome and one Y chromosome, can give either his X or Y chromosome. The egg (from the mother) already contains an X chromosome. Therefore the sex of a baby is determined by the X or Y chromosome of the sperm cell from the father. A baby girl will result if there is XX, and a baby boy will result if the final arrangement is XY. It is possible to have an abnormal arrangement of sex chromosomes, however, this is very rare.

Is it true that "boy sperm" swim faster, but die sooner and "girl sperm" swim slower but last longer?

Is it true that "boy sperm" last only 2 days and that to guarantee the boy child, ttc must be on or a day after ovulation?

re: Q: Gender determination?

No, I think they all live 3-5 days. However, Y sperm can be faster because the Y chromosome doesn't have as much genetic material as X chromosomes. So they are lighter. So I heard that there is a greater possibility of conceiving a boy but boys are more fragile during the 1st and 2nd trimester due to testosterone so they are more easily miscarried. And preemie girls do better than preemie boys. So it all evens out 50/50 girls to boys.

According to my doctor, all sperms are equal, which is why you are equally likely to have a boy or girl each time you conceive. Just like flipping a penny. If you flip it only 3 times you might get all heads (if you only have 3 kids, you might have all girls), but if you flip it 50 times, you'll get 50% heads, 50% tails overall.

The way they explained it in med school is that boy sperm are the sports cars, and girl sperm are the volvos. Boy sperm die faster, but are much quicker...girl sperm are slower but stick around up to twice as long. You can actually see the difference between X and Y sperm under magnification. Y sperm have much longer flagella (tails) and the heads are more streamlined. X sperm are clunkier looking, and the tails are shorter and fatter.

Q&A: How is my baby's gender determined?

My DH's family haven't had a girl born into the family for generations (freak abnormality?) so we expected our 20 week ultrasound to confirm another boy (he already has 2 sons previous). I was shocked when our tech said its a girl. He's only been wrong with less than 10 out of roughly 1500 births (and they were in the beginning of his career) so we're hoping he's right! We're both ready to buy some pink!

Q&A: How is my baby's gender determined?

Why do people use sex and gender interchangeably? Sex is your biological characteristics (male/female), and gender is what you identify with (masculine/feminine). How can you know what your baby identifies as when they are not fully developed as a person yet?
