If a woman is certain that she has not ovulated that month she will not get pregnant because pregnancy is the union of the ovary and the sperm to form a fertilized egg, and a woman will excrete 1-2 mature eggs every month after puberty. If there are no eggs, the basic conditions for pregnancy are lost, and therefore pregnancy will not occur. Therefore, clinically, women with polycystic ovary syndrome and ovulation dysfunction will definitely encounter difficulties in getting pregnant. For women with ovulatory dysfunction, it is important to actively conduct examinations to find out the cause of the problem and at the same time carry out treatment. Patients with polycystic ovary syndrome can adjust their menstrual cycle and induce ovulation in order to promote ovulation, while patients with premature ovarian failure, because of diminished ovarian function, will also affect ovulation and need to regulate the hormone level to restore the ovarian function of ovulation. Some women over dieting to lose weight will also affect ovarian function and ovulation, so it is important to lose weight in a healthy way.
