Patient's question:
What are the reasons for anovulation? What are the reasons why women do not ovulate? I took three B scans this month (starting on the 11th day of my period, every three days once), but I didn't find any dominant follicles. My period is often delayed. Is it because the time for taking the B is incorrect? What are the reasons for anovulation?Doctor's answer:
1. Hypothalamic disorders: They are classified into functional and organic types. The former includes idiopathic hypothalamic amenorrhea, psychogenic amenorrhea, functional hyperprolactinemia, and anorexia nervosa; the latter includes hypothalamic tumors, post-encephalitis, and post-traumatic head injuries.2. Pituitary dysfunction: Pituitary adenomas, Sheehan syndrome, tuberculosis or syphilitic granulomas.
3. Ovarian dysfunction: This includes primary ovarian failure and secondary amenorrhea. The former includes conditions like Turner syndrome. The latter includes premature ovarian failure, organic damage to the ovaries, such as loss of function after radiation exposure, and destruction caused by tumors or inflammation. The cause of anovulation needs to be clearly identified, and treatment should be targeted at the underlying cause.
