If it rains at the wedding, will the bride and groom have a good chance of having a boy?

Many people want to know whether they can have a boy or a girl. Science has proved that men are more likely to inherit the tendency to have sons or daughters from their parents. This means that men with multiple brothers are more likely to have sons, while men with more sisters are more likely to have daughters.

The research results of thousands of families in Newcastle University will help to judge that they are more likely to have sons or daughters as parents. Cowley, a scientist at Newcastle University, said. Galatri's research found that men inherited the tendency from their parents to have sons or daughters more easily. This means that men with multiple brothers are more likely to have sons, while men with more sisters are more likely to have daughters.

1. Does fertilization of sperm and eggs occur in fallopian tubes?

2. The fetus grows and develops in the uterus until it is delivered from the vagina?

A new life usually begins when fertile men and women have sexual intercourse, that is, when men and women have genital intercourse, the man transports hundreds of millions of sperm into the woman's vagina through ejaculation. These sperm are like tadpoles with tails, scrambling to swim to women's uterus, and some can even enter the fallopian tubes.

If you happen to meet a mature egg discharged from the ovary in the fallopian tube, the sperm will immediately surround the egg, and each sperm will try to penetrate the follicular wall and enter it. As a result of the competition, only one "lucky" sperm can successfully combine with the egg. Men decide the sex of their children according to whether their sperm carries X or Y chromosomes. The child born of the combination of male X chromosome and mother X chromosome is a girl (XX), and the child born of the combination of male Y chromosome and mother X chromosome is a boy (XY). Become a fertilized egg and be pushed into the uterus by tubal contraction. This has nothing to do with whether it rains or not.
