Scientists at Harvard Medical School in the United States conducted tests on killing sperm in three different formulations of Coca-Cola beverages currently sold. The conclusion is that newly-married men drinking cola-type beverages will directly harm sperm and affect men's fertility. ability. If the damaged sperm is combined with the egg, it may cause fetal malformation or congenital deficiency.
The medical scientists added the live sperm to a certain amount of cola drink, and measured the sperm survival rate after one minute. Tests have shown that the new formula of cola drink can kill 58% of the sperm, while the early formula of the cola drink can kill the sperm. They also advised newly-married women on drinking cola-type drinks, and advised them to drink less or not. Because most cola-type beverages contain caffeine, it is easily absorbed into the fetus through the placenta in the body, endangering the vital organs such as the brain, heart, etc., which can also cause teratogenic or congenital dementia.
Therefore, experts suggest that newlyweds and couples who want children should not drink cola-type drinks in addition to alcohol and tobacco.
"Catch" the egg four: I and my husband tried a lot of methods, but they can not make me pregnant, and finally we are really anxious, at any cost, did more than 10 B-ultrasound in one month, finally in The ovulation day was found with the help of B-ultrasound.
Expert comment: Monitoring ovulation day by B-ultrasound is a feasible method, but this method is more cumbersome and costly, it is a last resort. B-ultrasound monitoring of ovulation day mainly refers to the process of monitoring the size and rupture of follicles. After the 10th day of the menstrual cycle, the follicle can grow to a size of more than 1 cm in diameter. It will gradually grow up and rupture to a certain extent. The broken one is ovulation. In the first 10 days of the menstrual cycle, do B-ultrasound every 3 to 4 days. After the 10th day, do B-ultrasound once a day or every other day. Only when you do B-ultrasound frequently can you capture the opportunity of “breaking”. In short, B-ultrasound monitoring of follicles and ovulation days is a non-invasive, painless, accurate and good way, its shortcomings are more trouble, more expensive.
Detector to help
Detection principle: There is a very important relationship between the crystallization of saliva and cervical fluid and the concentration of ovulation luteinizing hormone (LH) during the physiological cycle, so the crystallization of saliva and cervical fluid can accurately reflect the presence of women. Physiological stage.
Usage: Saliva test, cervical fluid test.
However, due to individual errors and certain errors, this test has not been widely used in clinical practice.
Measured ovulation day
- "Catch" the egg three: After I have released all the contraceptive measures, my husband and I have not been "moving" for several months. It is really anxious for us. Is it because we have something wrong with us? So we went to the hospital to see the doctor. After the examination, we got the conclusion that "the two are physically healthy" from the doctor. However, this hospital has not gone to the hospital. The doctor pointed out the bright road for us - insist on measuring the basal body temperature every day and observe the ovulation day. I did it, of course it was successful!
Expert Comments: Determination of basal body temperature can accurately master their ovulation period. The basal body temperature measurement refers to the body temperature measured after waking up for 6 to 8 hours without any activity (such as talking, eating, or getting up). The measured body temperature records are linked into a curve by date, called the basal body temperature curve. The basal body temperature of ovulatory menstruation is biphasic, that is, the body temperature before ovulation is low, and the body temperature after ovulation is high. The turning point of the two is the ovulation day. The basal body temperature before and after ovulation differs by about 0.4 °C. This is because after ovulation, the corpus luteum is formed, and the corpus luteum secretes progesterone, which causes the body temperature to rise. The increase in body temperature after ovulation is divided into two different situations, one is a slight decrease, immediately rises, the other does not decrease, and the body temperature rises directly. The basal body temperature is an objective indicator for determining the ovulation date, and it is easy to measure and judge at home. It is best to measure the menstrual cycle continuously so that you can master the rules of your own ovulation. In addition, when measuring the basal body temperature, the factors that may affect the basal body temperature, such as cold and fever, and application of progesterone, should be excluded. Basal body temperature is one of the most accurate ways to capture ovulation days.
