Boy or girl is determined by chromosomes, which are inherited from parents. In a woman's life cycle, ovulation is a very important period. Research shows that when a woman ovulates, her egg cell divides into two, and half of them will contain boy chromosomes, and the other half will contain girl chromosomes. Therefore, a woman’s ovulation period is crucial for giving birth to a boy or a girl.

To determine when a woman is ovulating, women can observe changes in their body temperature. Research shows that a woman’s body temperature will rise by about 0.5 degrees Celsius during ovulation. In addition, women can also observe their vaginal discharge. Research shows that when women are ovulating, their vaginal discharge becomes clearer and increases in volume.

A woman's ovulation period can be determined through a variety of methods. Women can determine their ovulation period by observing changes in their body temperature and vaginal secretions. Additionally, women can determine when they are ovulating by using a thermometer and a tool that measures vaginal secretions.

A woman's ovulation period is crucial for giving birth to a boy or a girl. By determining when they are ovulating, women can better control their chances of having a baby and more easily choose the gender that suits them. Therefore, it is recommended that women pay attention to their physical health in daily life and check their health status regularly in order to better determine their ovulation period and grasp their fertility opportunities.
