The birth of a boy or a girl has little to do with body type, and is mainly determined by the type of sex chromosomes in the male’s sperm. At present there is not enough scientific evidence to show that the birth of a boy or a girl has a relationship with the body. Patients are advised not to listen to any folk rumors. From a scientific point of view, the birth of a boy or a girl is related to the neutral chromosome of the male sperm. Normal males contain two types of sex chromosomes, X and Y. If the X chromosome is present, it is a girl; if the Y chromosome is present, it is a boy. To establish a good concept of equality between men and women, do not deliberately pursue the gender of the baby. In the process of preparing for pregnancy, it is important to eat a balanced diet and nutrition, strengthen physical exercise, and supplement folic acid, which is conducive to the healthy development of the baby. If you have any other questions, it is recommended to consult a professional doctor for guidance.
