The birth of a boy or girl depends on the tadpole that combines with the egg. If it carries the X gene, it will give birth to a girl, and if it carries the y gene, it will give birth to a boy. So once conception occurs, the gender of the fetus is determined. If you want to prepare for a baby girl, you should prepare three months in advance.
1.Chromosome
A new human individual develops from the combination of sperm and egg into one fertilized egg. A fertilized egg has 46 chromosomes like normal human cells, half of which come from the father\’s sperm and half from the mother\’s egg, so the baby is both like his father and his mother.
The gender of the fetus is determined at the moment of fertilization. The key to the decision lies in the male, not the female. 
2. Adjust the pH of male daddy
The pH value of normal human blood is 7.3-7.45, which is slightly alkaline. Studies have found that strenuous exercise has an impact on the pH of human blood; strenuous exercise makes metabolism particularly strong.
3. The probability of having more girls
If you want to have a girl, male fathers can increase exercise before conception to increase the acidic metabolites in the blood, and eat acidic foods and fruits such as vitamin C.
4. The probability of having more boys
If you want to give birth to a boy, male fathers should take a rest a few days before conception, or take alkaline foods such as baking soda orally.
5. Acidic foods
Commonly found in meat, eggs, cheese, sugar, tuna, halibut, ham, chicken, pork, mandarin fish, beef, bread, butter, white rice, peanuts, chocolate, fried tofu, wheat, egg yolks, hollow noodles, Bacon and more.

7.Select days
If you have intercourse on the correct ovulation day, you have a high chance of giving birth to a boy. If you have intercourse three days before the ovulation day, you have a high chance of giving birth to a girl. On the ovulation day, you can use ovulation test strips, body temperature detection, or B-ultrasound to detect follicles. . 
8. ThinkWhen to choose a baby boy
