Ovulation refers to the process during the female reproductive cycle when eggs are released from the ovaries to the fallopian tubes. During this process, a woman's body will undergo a series of changes, which are crucial for women's pregnancy and childbirth.

In addition to the fertile period, women also experience a series of other physiological changes during ovulation. For example, their sexual desire increases and they may feel more aroused and sensitive. Additionally, their eyes may become brighter, their skin may become smoother, and their body odor may become more unpleasant.

These physiological changes are crucial for women during pregnancy and childbirth. If women can seize the opportunity during the fertile period for sperm and egg to meet, then they are expected to have a smooth pregnancy and delivery.

However, a woman's menstrual cycle and fertility are affected by many factors, such as genetics, diet, exercise, stress and health conditions. Therefore, if women want to become pregnant, it is best to consult a doctor or a professional fertility counselor to ensure that they are in the best physical and psychological condition.
