Changing the acid-base separation of sperm with X and Y chromosomes in different acid-base environments has different swimming speeds: sperm with Y chromosomes are more active in alkaline environments, while sperm with X chromosomes are more active in acidic environments. Therefore, if the couple hopes to have a girl, they can dilute acetic acid with a small amount of clean warm water and then rinse the woman's vagina to make the vagina acidic.

Sexual intercourse temperature German researchers traced birth records between 1946 and 1995 and compared them with local temperature changes. The results showed that April to June in the local area are the months with the most baby boys born, while October is the month with the least baby boys born. Further analysis shows that the environmental temperature one month before the fertilized egg is fertilized, that is, the temperature of the environment in which the boy and girl are one month before sexual intercourse, is an important factor affecting the baby's gender. A high temperature environment is more likely to produce a baby boy, and a low temperature environment is more likely to produce a baby girl.

Many people know that if you want to have a boy, deep penetration is the best during sexual intercourse. So, if you want to have a girl, should it be the other way around, shallow penetration? In fact, there is no doubt that this is indeed the case. If the man adopts the method of shallow penetration, the ejaculated sperm will definitely stay in the acidic vagina for a period of time, allowing the Y sperm to be screened as much as possible, leaving only the X sperm, so that the probability of having a girl can be increased.
