Is there any scientific basis for the positive ovulation test result in a boy?

There is a saying among the people that if the ovulation test paper shows a strong positive, it is easiest to have a boy at this time. However, experts say that this saying has no scientific basis, because whether the boy or girl is born is determined by the man, and a strong positive only means that the woman is ovulating.

1. How long does it take for ovulation to be born after the ovulation test paper shows a positive result?

According to the principle of ovulation test paper, find the most suitable method to detect ovulation with ovulation test paper, that is, use ovulation test paper to detect once a day about a week after the end of menstruation. If you find that the ovulation test paper starts to become strong and gradually strengthens, you should increase the frequency of testing, preferably once every 4 hours. If you compare the test strips and find that the ovulation test strip begins to weaken and quickly becomes weaker, it means that ovulation is about to occur and you can plan to have sex. The 24-48 hours after the ovulation test paper turns weak is generally the time range for ovulation.

From a biological perspective, Y sperm are more active and swim faster, but have a shorter lifespan; X sperm swim slower and have a longer lifespan. It is estimated that Y sperm lives for one day and X sperm lives for 2-3 days. The egg can live for 2 days.

Because after ovulation, the egg is already in the uterus. If you have sex at this time, the Y sperm will swim very fast and combine with the egg as soon as it enters the uterus. X sperm has not yet reached the uterus and is slower than Y sperm. So XY combined to give birth to a son.

If it is before ovulation, the Y sperm enters the uterus first, but the egg has not been released yet, the Y sperm may wait until it dies, and the egg has not been released yet. Then the X sperm enters the uterus and combines with the egg, so the XX combination will give birth to a daughter.

This is the most scientific secret for giving birth to a boy or a girl. Orgasm can also help in having a son, but this only works if you have sex after ovulation. If the Y sperm are dead, orgasm will only help the X sperm enter the uterus and give birth to a daughter.

Therefore, friends who want to have a son can use ovulation test strips. When the two lines are almost the same depth, you should pay attention, because ovulation may be approaching. At this time, you no longer need to test once a day, but every four hours or even two hours. When the two lines are the same depth, test once every four hours. When you observe that the color starts to fade, it means ovulation has occurred, and this is the best time to have sex.

2. This has no scientific basis. A strong positive result from an ovulation test strip only means that ovulation is about to occur or has already occurred, but it does not prove that pregnancy is possible. In fact, this cannot determine the gender of the fetus. The gender of the fetus cannot be artificially intervened. Let nature take its course. The hospital will not conduct examinations in this regard. Unless there is a genetic disease that requires gender identification, this requires a diagnosis from a clinician. The accuracy of ovulation test strips is limited, not 100% accurate. The test results of the test strips can only be used as a reference. The sperm-egg combination is definitely high within 24-48 hours after showing a strong positive, but it is not 100% accurate. Conception is a complicated process, not as simple as imagined.

3. What is the reason for the ovulation test paper to turn from strong positive to weak?

The follicles develop and mature under the action of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Within 24 hours before ovulation, there will be a peak in LH, and it will definitely occur. Therefore, use ovulation test strips to detect this peak. When the color of the second line on the test paper is close to, the same as, or exceeds the color of the first line, you know that ovulation will occur within 24 hours. It's very intuitive and clear, and there's plenty of time to prepare. It should be noted that the appearance of two lines (i.e. positive) does not necessarily mean ovulation. There are also weak positive and strong positive. Only when a strong positive appears (i.e. the two lines are almost the same color or the test line is darker than the control line) does it indicate that ovulation will occur within 24-48 hours. Therefore, when a strong positive test appears, test twice or more per day. If the color starts to lighten, then the previous measurement was the peak.
