Improving the probability principle
The male XY chromosomes are random, so theoretically the chances of giving birth to a boy and a girl are 50% each. However, the ratio of male X chromosomes to Y chromosomes is not 1:1, and their motility is also different. If the male has more Y chromosomes during intercourse, the chance of having a boy is greater; otherwise, the chance of having a girl is greater with X chromosomes.
Method 1: Diet conditioning
Tadpoles with the X chromosome (female) are more active in an acidic environment. Tadpoles with the Y chromosome (male) are more active in an alkaline environment
Common alkaline foods
Strongly alkaline: grapes, tea, kelp, citrus, persimmon, medium alkaline: tomatoes, spinach, banana, strawberry, lemon, weakly alkaline: tofu, cabbage, cabbage, apple
Common acidic foods
Strongly acidic: egg yolks, cheese, desserts, white sugar, cheese, medium acidic: sausage, bacon, beef and mutton, toast, weakly acidic: chocolate, rice, peanuts, fried tofu,
2AA techniques
X chromosome (female baby): swims slowly and survives long
Y chromosome (male baby): swims fast and has a short survival time
When preparing for pregnancy, arranging AA on the day of ovulation has a greater chance of conceiving a boy, and arranging AA 3 days before ovulation has a greater chance of conceiving a girl.
Want a boy
On the day of ovulation, the female fallopian tube is in an alkaline environment, and the number of tadpoles with the Y chromosome is dominant. The vitality of the Y chromosome is better. :Swimming fast, short survival time. When preparing for pregnancy, if you arrange an AA on the day of ovulation, you will have a greater chance of conceiving a boy. If you arrange an AA 3 days before the ovulation day, you will have a greater chance of conceiving a girl. 
Want a baby girl
In the three days before ovulation, the female uterus is in an acidic environment, which is more suitable for the survival of X chromosomes, and the number and vitality of X chromosome tadpoles are better. Arrange AA 3 days before ovulation, or arrange AA every 3 to 5 days before ovulation to increase the chance of having a girl.
How to determine ovulation day
①Menstruation: 1 month before the next menstruationOvulation takes place around 4 days, and there is a lot of stringy leucorrhea on that day.
② Use test strips: When there is strong Yang, ovulation usually occurs 1-2 days later.
③ Follicle monitoring: do it on the day when the test paper reaches strong positive, the follicle reaches 17mm, the endometrium reaches 8mm or more, ovulation can be done at any time, the follicle reaches 20mm, and the endometrium reaches 10mm.
④Body temperature: The body temperature rises by 0.2-5 degrees after ovulation.
