Husband and wife a boy or woman by what decision?

Older people prefer boys because they can continue the family incense, but now many young parents prefer girls, because her daughter caring, understanding; although the gender of newborn babies medical findings have not yet matured, but people still want to control the a boy or woman, here are often brought in several dimensions.

PH of food

Over the years, research statistics, that food does affect the pH of a boy or woman probability. Want to Huai boys, women usually want to eat more alkaline food, men should be taking in a balanced diet; want to pregnant girls and women to avoid eating too much alkaline food, but do not eat too many acidic foods, so as not to affect their physical health, both men and women are taking in a balanced diet can be.

Alkaline foods include: beans (with pods or green beans), vegetables, fruits (bananas, plums, processing exception of fruits), fresh milk, grains (such as corn), tea, kelp, algae, yeast, iodine, calcium, Vitamin D.

Acidic foods include: all meat, fish, in addition to fresh milk, dairy products (such as butter, ice cream, cheese, flavored milk), wheat, rice flour products, canned food, corn, protein, sour fruits, chocolate, beverages, vinegar.

Age factor

Men's sperm count will decrease with increasing age, so the chances of a girl is particularly high, it is has been proven fact. Similarly, older women, due to the impact of the aging effects will make the alkaline secretions within the uterus was lowered, a girl's chances greatly improved. Therefore, older couples a better chance of daughters young couples high, it is an indisputable fact.

Occupational factors

According to statistics, the report pointed out that the men's job if the driver of a long drive (for example, taxi drivers, truck drivers), flight attendants or pilots, anesthesiologists, in the deep-sea divers to work, the chances of a girl are particularly high. This is because the? Pill by high temperature, pressure, or strong changes in water pressure, or toxic inhalation anesthetic gases, leading to less robust vitality of the Y sperm die first, resulting in a girl's chance to particularly high.

Stress factors

Men's long under pressure would reduce the number of sperm; women are too tight will have a strong acidic environment conducive to Y sperm survival. Therefore, the work pressure is too large, pressure of having children who are particularly vulnerable to birth to girls. If you want a boy, the pressure is not too much, relax.

　Men's wear

If the ordinary man would often wear a body suit scrotum temperature rise, resulting in reduction in the number of sperm, a son of the Y sperm will die first, so that greatly increased the chances of a girl may also be temporarily infertile. If you want a boy, must be prevented through a high scrotal temperature, so men should pay special attention not to wear tights pants.

　Vegetarian pregnant women prone

British scientists found that pregnant women with relatively easy vegetarian daughters. Scholar who led the study, Ms. Hudson said that although there is no other studies of pregnant women to explore the impact of diet on the sex of their child, the study continues to suggest that pregnant women, vegetarian food on the sex of their child has a direct impact. The Nottingham University study found that the number of British male and female ratio was 106 compared with 100, but the vegetarian pregnant women gave birth to her son and daughter, the ratio of 85 than the 100. The data show that pregnant women with relatively easy vegetarian daughters.

Expert: Sex ratio constant of the most important

Of human reproduction is concerned, naturally has a very wonderful, very consistent with the phenomenon of human development, that is, sex has maintained a relatively constant proportion of men and women a rather large population, which is to maintain social development and stability, and prosperity of human reproduction It has very important significance. Some of the above factors, some only in theoretical reasoning, but rather think speculation has not been systematic, comprehensive, large sample studies, and therefore a lack of scientific nature. If you really can rely on the pH changes in diet, changing eating vegetarian, etc., you can change the probability of a boy or woman, I am afraid there is not enough convincing
