Each person has a part of the other

The human world - the most miraculous product of creation - is a combination of two factions: male and female. This distinction is not radical, because in every man there is a part related to women.

Naturally, each person is born with 22 pairs of normal chromosomes and 1 pair of sex chromosomes. Your baby will be a son when you have a pair of sex chromosomes, XY and a girl with a pair of XX. Globally, the ratio of babies born to boys and girls is 1/1. This harmony has shown a very natural thing: No one is alone in the world, everyone has the opportunity to find his or her half.

For girls, the 46XX chromosome shows that on two long and short wings of the X chromosome, they contain genes for normal ovarian development. For boys, the Y chromosome has a TDF sex determination gene, which determines the development of the testicle.

At week 6 of the fetus, female and male genitalia are the same. But then, this department gradually differentiated. At week 8, in XY fetus, Leydig's cell testicles begin to function and secrete testosterone. This is a hormone that causes male to create vas deferens, epididymis, seminal vesicles, develop penis, and also testicles move from the abdomen to the scrotum.

Whereas in women, because there is no sex determination gene on the Y chromosome, the gonads develop into ovaries in the 10th week of pregnancy. Oocytes (egg cells) are present in the fourth month and reach 7 million oocytes in the 5th month. At birth, the ovaries have about 1 million active cysts and are reduced to 0.5 million capsules when available. periods. The main hormone of the ovary is estrogen.

The dominance of the X chromosome in both sexes demonstrates the important role of women in men not only in daily life but also in the law of creation.

Unknown people are male or female

The 'forgetfulness' of nature has inadvertently made many people unable to determine what gender they belong to, making life difficult. Medicine is constantly finding effective measures to correct this mistake of creation.

Klinefelte syndrome in boys : The incidence of 1 / 1,000-1 / 500 postpartum boys is still alive. Less diagnosis is made before puberty. Children often have symptoms of mental retardation, little activity, shame, tall people, smooth skin, long legs, fat or overweight, testicles and small penis for age and slow puberty.

Turner syndrome in girls : Characteristic is dwarf, non-pubescent, without ovaries and uterus. The disease can be detected soon after birth with manifestations of ancient skin folds such as fan-shaped, low weight and height, edema in the back of hands and feet. But in fact, children are usually only diagnosed after 5-7 years of age due to lack of height, dwarfism and delayed puberty.

There are male appearance children, but the internal genitalia is female, common in congenital adrenal hyperplasia, genetic diseases recess on normal chromosomes. The reason is that the body lacks specific enzymes for the synthesis of cortisol hormone of the adrenal cortex.

For girls, due to early male genitalia in the fetus, immediately after birth, the family misnamed the son. For simple maleization, children come to the hospital later because they show early puberty, the external genitals look like men but children urinate to sit. The test shows the chromosome 46XX, the ultrasound has the uterus and ovaries.

There are female appearance children but the internal genitalia is male. This is an androgen-free syndrome; Although children have testicles, still produce testosterone, the target cells do not respond to this male hormone so the body is not maleized. The baby has a completely female appearance but the chromosome is 46XY, has testes, no uterus and ovaries.
