Where do you start to prepare for a big baby? If you happen to be preparing to get pregnant too, then there are 15 numbers of knowledge that you must know. Do you want to know how long the sperm and egg live? Do you want to know how to calculate ovulation during your menstrual cycle? Do you want to know when is the easiest time to conceive? Do you want to know how to do will increase the success rate of conception? Do you want to know what precautions to take before pregnancy? Remember the 15 numbers, so you can easily prepare for pregnancy. The number is the survival time of the egg. The strongest fertilization ability of the egg is within 24 hours after ovulation. If the egg enters the fallopian tube and meets the sperm within 24 hours, the sperm and the egg can unite for fertilization, if the sperm and the egg lose the opportunity to meet at this stage, the egg loses its ability to fertilize and dies. Therefore, generally speaking, you can only have intercourse within 1 to 2 days before and after ovulation to have the possibility of pregnancy. 2. 2-3 days This number is the time for sperm to survive in the woman’s body. Although sperm can only survive for a few minutes in the natural environment outside the body, they can survive inside the woman’s body for up to 3 days. The magical time difference also provides more possibilities for the sperm to meet the egg for fertilization. 3. 6-7 days This is the time it takes for the fertilized egg to complete its implantation. Many people are not sure how long it takes for the sperm and egg to unite and how long it takes for the sperm and egg to unite before pregnancy occurs. Generally, the fertilization process takes 24 hours and the embryonic follicle begins to implant on the 6th-7th day after fertilization. The location of implantation is mostly in the upper third of the uterus. The completion of implantation means that the embryo has been placed and the placenta has started to form, conceiving the fetus. The secret of the menstrual cycle and ovulation 1. 14 days If the menstrual cycle is regular, a woman’s ovulation usually occurs about 14 days before the next menstrual period. The 5 days before and 4 days after the day of ovulation, together with the day of ovulation, a total of 10 days is called the ovulation period. During this time, luteinizing hormone rises rapidly, stimulating the ovulation of the egg. At the same time, the cervical mucus becomes lubricated, making it easier for the sperm to meet the egg. 2. 7 days This number is the effective time for conception during ovulation. Generally speaking, the egg does not survive for more than 3 days and the sperm does not survive in the woman’s body for more than 4 days. In other words, the effective time for conception during ovulation is usually 5 days before the woman ovulates, because sperm can survive in the woman’s body for up to 5 days, and 2 days after the woman ovulates, because the egg can only survive in the woman’s body for 2 days after it is discharged, which means that the effective time for conception is usually about 7 days. 3. 0.3-0.5°C During ovulation, your body temperature will rise by 0.3-0.5°C. Ovulation usually occurs before or during the rise in body temperature. A woman’s basal body temperature usually changes with ovulation. In the first half of a woman’s menstrual cycle, the fluctuation of body temperature is below 36.6 degrees, and after ovulation, it will turn into the second half of the menstrual cycle, and normally the body temperature is a little higher than the first half, with normal fluctuation between 36.6 degrees and 37 degrees. If the body temperature rises, it means that ovulation has occurred, and after a high temperature period lasting about two weeks, the woman’s body temperature After a high temperature period lasting about two weeks, the woman’s body temperature will decrease again. Time of conception: when is the easiest time to get pregnant 1. 17:00-19:00 This number is the best time of the day to conceive. The Italian scientist Kaniachi pointed out that scientific research has long found that hormones play a key role in influencing women to conceive, and that it can make most women ovulate between 5 and 7 p.m. (17:00-19:00). This scientist also found through experiments that 2. 28 years old The age of childbirth should try not to exceed 28 years old. Because with age, human fertility is decreasing, in addition, too late pregnancy, egg quality decreases, the chances of embryo malformation increases. Also, it is not conducive to timely detection of problems, which makes treatment more difficult. Generally speaking, men’s age is 30-35 years old when they give birth to the best offspring; physiologists recognize that the best age for women to give birth is between 23-28 years old, a period when women’s whole body is fully developed and mature, the quality of eggs is high, and if they carry a child to term, women have fewer complications, less risk of delivery, good fetal growth and development, and The incidence of premature birth, deformed and demented children is the lowest. August and September are the best months of the year to get pregnant. From the medical point of view, there are three critical periods for embryonic development: the first is the brain formation period, which is the third month of conception; the second is the brain cell division period, which is after the sixth month of conception; and the third is the coordination period for transcellular development, which is the seventh to ninth month of conception. If you choose to conceive between August and September, the third and sixth months of pregnancy and the delivery period are in the late autumn and mid-spring seasons when the climate is suitable and nutrition can be easily deployed, so the fetal nervous system can be well developed. Chances of conception: How to improve the success rate of conception 1. 24 A woman with a BMI of 24 has a high success rate of conception. An American study found that women with a BMI close to 24 were twice as likely to conceive as other women. What is your BMI? The formula is: BMI = weight (kg) ÷ height (m) / 2; in fact, the BMI is 24, is a slightly fat body, if your index happens to be 24, do not struggle to lose weight, maintain this figure, because it will make you more likely to conceive than others. 2. 10% For every 10 kg increase in women who are on the lean side, the chances of pregnancy will increase by 10% accordingly. So it is important to control your weight before pregnancy. According to the previous article, you can set the standard weight for the most fertile as BMI = 24 if 3. 1.7% This is the chance of a twin woman conceiving to have twins again. Scientists, through a survey of families with twins, found that 4% of twins whose mothers were also twins, and only 1.7% of twins whose fathers were twins. The genetic predisposition to conceive twins is mainly on the mother’s side, and women who are twins themselves have a 1.7% chance of having twins, while women who are not twins but whose parents are twins have a 0.8% chance of having twins. If the mother is a twin, then the chance of having twins is 1.7%. Tips for preconception body conditioning 1. 400 micrograms This is the amount of folic acid you should not exceed in your daily supplement when preparing for pregnancy. Although the need for folic acid supplementation varies from person to person, experts agree that more folic acid supplementation is not better than more, and if you take too much folic acid supplementation instead, you will make a mistake and bring side effects. Taking more than 350mg of folic acid tablets may affect the absorption of zinc, and the lack of zinc may lead to fetal growth retardation and an increase in low weight babies. Some people who take folic acid in large doses for a long time may develop gastrointestinal disorders such as anorexia, bloating and nausea. …… Finally, try to take folic acid supplements and eat more green leafy vegetables. 2, 20% Men who smoke more than 30 cigarettes a day, the proportion of deformed sperm exceeds 20%, and the longer the smoking time, the more deformed sperm. Stop smoking six months later, the sperm can return to normal. If both spouses or one of them smokes regularly before pregnancy, the harmful components in tobacco will enter the reproductive system through the blood circulation, and toxic effects will occur directly or indirectly. Therefore, the couple preparing for pregnancy, at least 3 months before pregnancy should quit smoking. 3. 5-10 reps Do sit-ups 5-10 times a day before pregnancy can improve your pregnancy power. Some women do not like to exercise, some experts say that if you do more foot exercises, you can strengthen the blood circulation in the lower abdominal cavity, reduce the discomfort caused by long hours of sitting, and avoid congestion in the brain. Do sit-ups 5-10 times a day, can strengthen the strength of the rectus abdominis muscle. Weak rectus abdominis muscle strength is a sign of poor physical strength and is also related to the physiological function of the Ren and Uterus. Therefore, more exercise can enhance the pregnancy strength, for the future physical load of pregnancy and birth are very helpful.
