Women have an ovulation period after their physiological period, and only if they ovulate normally, then they may conceive. What are the reasons for non-ovulation? 1, ovarian lesions If you do not ovulate, then you should check if there is a problem with your ovaries. Because the ovaries are the place where the eggs are conceived and produced, if there is a problem with the ovaries, then it may lead to problems with the eggs as well. If the patient has congenital ovarian insufficiency, premature ovarian failure, ovarian tumors and other diseases, it may lead to abnormal ovulation in women. 2, hypothalamic-pituitary-ovarian axis dysfunction This cause sounds a little scary and even more awkward to pronounce. It may be simpler to explain it this way. The regulation of the menstrual cycle is mainly controlled by the hormonal action of the hypothalamus, pituitary gland and ovaries. It’s like a tree whose trunk is sick, so the branches and leaves can’t flourish. This system that controls menstruation is often dysfunctional in the brain due to bad emotions such as tension, anxiety, anger, sadness, stress, etc., causing non-ovulation or abnormal ovulation. Therefore, women who are preparing for pregnancy should pay special attention to keep a comfortable and happy mood and relaxed mind is also important. 3. Other diseases There are too many other diseases. For example, malnutrition can lead to endocrine disorders, which can affect the normal function of the ovaries. Of course, there are many other systemic diseases. If one of the couple preparing for pregnancy has a disease that has not yet been cured, then they should actively treat it and wait for their bodies to heal before preparing for pregnancy, so that they can conceive a healthy and lovely baby.
