The scientific principle of giving birth to boys and girls

As early as the 1970s, scientists studied this problem. Researchers usually use pH value to represent pH value. When the pH value is equal to 7.0, the solution is neutral, less than 7.0 is acidic, and more than 7.0 is alkaline. The researchers washed and soaked the two kinds of sperm with acidic and alkaline solutions with pH value of 5.2-8.0, but the results showed that there was no significant difference in the vitality of X sperm and Y sperm. Some researchers also treated rabbit sperm with solutions with different pH values and then artificially inseminated them. There was no significant difference in the sex ratio of rabbits born. Moreover, in this experiment, the proportion of male rabbits born by sperm soaking in acidic solution is slightly higher, but it is not statistically significant. It can be seen that there is no scientific basis to support the statement that "X sperm is acid-resistant and Y sperm is alkali-resistant". Therefore, the method of washing vagina with alkaline solution can not increase the chance of having a boy, but will easily suffer from vaginitis because it destroys the normal acidic environment in vagina. If you are infected with vaginitis during pregnancy, there will be a risk of miscarriage and premature delivery in severe cases.
