How to increase the chance of having a baby?

Published: 2008-07-28 Author: Blue Spirit Parenting Network editor Parenting Network h20pulse.com

Netizens ask: How can we increase the chance of having a baby? What kind of lifestyle do you eat or pay attention to? I have noticed a message that sperm with female chromosomes like acidic environment, and sperm with male chromosome like alkaline environment. Is this correct? Anyway, I'm afraid of giving birth to a girl!

Professor Youtou Huang: Hello, Beibeiyin does not support choosing a child's gender. There are many situations that affect boys and girls.

How is the sex of the fetus determined?

Why do some people want boys and give birth to girls? Why do some people need girls to give birth to boys? What is going on with boys and girls? There have been various speculations in history, but they have no scientific basis. It was not until the early 20th century that scientists discovered the chromosomes in human cells that unlocked the mystery of sex. It turns out that boys and girls have sex chromosomes in a fertilized egg.

Every cell of the human body (including germ cells) has 23 pairs of chromosomes carrying genetic material, of which 22 pairs are autosomes, which determine all genetic information except gender, and the other pair are sex chromosomes, which determine the sex of the fetus. Autosomal men and women are the same, there is no gender difference. Sex chromosomes are different. A pair of sex chromosomes in men is composed of X and Y chromosomes (XY), and a pair of sex chromosomes in women are X chromosomes (XX). Half of the 23 pairs of chromosomes come from the father and the other half from the mother.

Human cells multiply by division, that is, one cell divides into two, and two divides into four, so that it continues to divide. During the development of immature germ cells into mature germ cells, the chromosomes in the cells undergo a meiotic division, that is, the mature sperm or egg contains only 23 chromosomes, which is half of the original, 22 of which are Autosomal, one is a sex chromosome. A male pair of sex chromosomes is XY, so after the mature sperm is divided, one with X sex chromosome is called X sperm, and the other with Y sex chromosome is called Y sperm. A female's pair of sex chromosomes is XX, so the eggs after division and maturity all contain one X sex chromosome. It can be seen that there are two types of sperm in men and only one type in women.
