With the comprehensive opening of China's two child policy, many families want to have another child. The most important thing for the Chinese people is that they have both sons and daughters. For the gender of the second child, mothers want to make up a "good" character. Some mothers have a baby coat at one birth, and the second child wants to add a boy. So what is the secret of a scientific boy? Does it have anything to do with ovulation day?
The gender of the fetus depends on whether the X or Y sperm combines with the egg. The human will cannot determine the gender of the fetus. So, how can we have a boy? Japanese obstetricians and gynecologists have found that nearly 80% of women who have sex on ovulation day give birth to boys. This is because on ovulation day, the female vagina is weakly alkaline, and the activity of sperm is very high. At this time, Y sperm will swim twice as fast as X sperm. Two or three days before ovulation, when the female vaginal secretions are acidic, there is a greater chance for the X sperm to combine with the egg and give birth to a girl. Since the probability of having sex with a boy on ovulation day is so high, how should women calculate ovulation day?
Calculating a woman's ovulation date based on her menstrual cycle is the simplest method, but this method is only applicable to women who have a regular menstrual cycle. If women with irregular menstrual cycles use this method, there will be significant errors. The calculation method for ovulation period is as follows: starting from the first day of the next menstrual cycle, the last 14 days or minus 14 days are the ovulation day. The ovulation day, along with the first 5 days and the last 4 days, added together for 10 days is called the ovulation period. For example, if the menstrual cycle is 28 days and the first day of menstruation is on the 4th, then the 20th is the ovulation day and the 16th to 24th are the ovulation period.
Under normal circumstances, a woman's basal body temperature suddenly drops on ovulation day, and then rises by 0.3-0.5 degrees Celsius in the following days. Specific practice: It is necessary to maintain 6-8 hours of sleep every day, and immediately measure oral temperature when waking up in the morning without any activity (such as speaking, eating, or getting up). At least for 14 days, it is best to continue measuring and recording, and drawing a curve graph, in order to grasp the pattern of temperature rise and fall and determine one's ovulation day.
