Mild elevation of blood glucose usually does not significantly affect ovulation; however, severe elevation of blood glucose, insulin resistance or even diabetes may affect ovulation. Ovulation in women is regulated by a variety of endocrine hormones. Women who usually have regular menstrual cycles, ovulation usually occurs about 2 weeks before menstruation, and if menstruation is usually irregular, then the time of ovulation may not always be certain. Elevated blood glucose may trigger insulin resistance or even diabetes, which will affect the level of sex hormones in women’s bodies, and may easily lead to elevated testosterone levels and thus polycystic ovary syndrome, hyperandrogenemia and other diseases, which will affect the development and quality of follicles, leading to follicular maturation disorders and abnormal ovulation.
