The reasons why women’s follicles do not ovulate are as follows: First, it may be due to the unstable level of hormones secreted by the body. Second, may be suffering from inflammation of the ovary, blocking the normal discharge of follicles. Third, when a woman suffers from endocrine disorders, such as hyperthyroidism, can also lead to follicular maturation without ovulation. When women in this situation need to go to the hospital to do gynecological ultrasound and sex hormone examination. Due to hormone level disorder, ovulation drugs such as clomiphene and urotropin need to be given to promote ovulation. If necessary, the follicle can be surgically punctured so that the egg can be released before pregnancy can occur. When the follicle is not mature enough to ovulate, even if sex occurs, there is no egg and no sperm to combine, so pregnancy cannot occur.
