Pregnancy what conditions must have (1)

  Pregnancy must meet the following conditions: 1.Both men and women can produce normal germ cell。Such as when men with azoospermia, women are not pregnant。
2.Fertilization process involved must be unobstructed passage。If the fallopian tube obstruction can not be pregnant。3.Intercourse appropriate time。
Menstrual cycle, only one time of ovulation, ovulation within 24 hours after fertilization ability is the most time。
Sperm into the female reproductive tract can survive 2?3 days。
That is, only before and after ovulation intercourse, it may be pregnant。
4.Uterus ready for implantation of a fertilized egg。Menstrual cycle, the uterus is only sensitive to a very short period, to allow implantation of fertilized eggs。
  Diet should not be too high likelihood of fetal birth weight of high-sugar diet high blood sugar group, the incidence of fetal malformation, appears toxemia of pregnancy or times of opportunity needs Caesarean section, were three times lower blood sugar group of pregnant women, 2-fold and 7-fold。On the other hand, high blood sugar will increase the burden on the kidneys of pregnant women, adverse prenatal care。  High protein diet during pregnancy should not be high-protein diet, it will affect the appetite, increase the burden on the gastrointestinal tract, the human body can produce large amounts of hydrogen sulfide, histamine and other harmful substances, easily lead to bloating, loss of appetite, dizziness, fatigue and other phenomena。  If not long-term high-fat diet high-fat diet, it is bound to increase the risk of cancer of the reproductive system suffering daughter。Long-term eating high-fat foods may increase the large intestine of bile acid and neutral cholesterol concentration, at the same time, high-fat foods can increase the synthesis of prolactin to promote breast cancer, adverse maternal and child health。  If calcium diet should not blindly calcium diet, drink a lot of milk, add services calcium, vitamin d, etc., detrimental to the fetus。Nutritionists believe that pregnant women, calcium excess, the fetus may have hypercalcemia, after birth, children will fontanelle closed too early, widening jaw and prominent, adversely healthy growth and development。  Moldy food unfit for human consumption if the consumption of mycotoxin contamination of agricultural products and food, will not only acute or chronic poisoning, even bring disaster to the fetus。
Because 2-3 months early pregnancy, embryo implantation and development, somatic embryo is at the height of proliferation, differentiation stage, against mycotoxins can chromosome breakage and distortion, resulting in genetic disease or birth defects, such as congenital heart disease, Down's syndrome, and some even stop the development of the fetus and stillbirth, miscarriage。On the other hand, late in pregnancy, fetal organs because the function is not perfect, especially the function of the liver, kidney fragile, mycotoxins also have toxic effects on the fetus。
  In this special time of pregnancy, at the same time to protect themselves, but also to protect the calf, so whether in life or diet, should be careful。Especially in the diet, there are many people that need Bulletin boards taboos。
