When is a girl pregnant? Uncovering the secrets of scientific methods and folklore
In recent years, the topic of "having a boy or a girl" has been the focus of attention for families preparing for pregnancy. Although modern medicine has made it clear that the gender of the fetus is determined by chromosomes (XY is a boy, XX is a girl), there are still many parents who hope to increase the probability of giving birth to a girl through scientific or folk methods.

|---|---|---|
| Ovulation time | X sperm survive longer, and intercourse 2-3 days before ovulation may increase the probability of giving birth to a girl. | "Human Reproduction" Journal Research (2010) |
| Acid-base environment | An acidic environment is more conducive to the survival of X sperm, but vaginal pH is difficult to control artificially | Controversial and lack of clinical evidence |
| Parental age | Older fathers may increase the probability of giving birth to a girl (Y sperm motility decreases) | National Academy of Sciences Statistics (2008) |
