Generally, women of childbearing age discharge one mature egg per month, while ovulation disorder, which refers to a woman’s inability to discharge normal eggs, i.e. non-ovulation, is one of the main causes of female infertility, accounting for about 25-30%. There are many causes of ovulation disorders in women, such as endocrine disorders, ovarian lesions, and some systemic diseases that may cause ovulation disorders to occur. 1. Systemic diseases: such as severe malnutrition and hyperthyroidism can affect ovarian function and lead to anovulation. 2, ovarian lesions: such as congenital ovarian hypoplasia, polycystic ovary syndrome, premature ovarian failure, functional ovarian tumors, ovarian endometriotic cysts, etc., can also lead to anovulation. 3, endocrine disorders: hypothalamic-pituitary egg-ovarian dysfunction can cause anovulatory type menstruation, menstrual irregularities, amenorrhea, etc. 4. Other causes: The effect of caffeine-rich beverages such as coffee, strong tea and cola on infertility has not yet been unanimously concluded, but it is generally recommended not to overdo it. In addition, smoking and drinking alcohol, both for men and women, can affect fertility, so you should quit when you are ready to have children, and avoid too much high-calorie food in your diet. In addition, obesity or being too thin can interfere with the coordination of the endocrine system, and weight control can help prevent and treat ovulation disorders. Symptoms of ovulation disorders Ovulation is a physiological process and most people do not feel anything special. A small number of people may have the following discomfort: 1. feeling backache and slight pain in the lower abdomen during ovulation, but there are many diseases that can also show backache and abdominal pain. 2. Small amount of vaginal bleeding: Some people have a small amount of vaginal bleeding in between periods, which is less than the normal amount of periods. 3.Increased leucorrhea: Most people will experience an increase in leucorrhea during ovulation, which becomes as transparent as egg white and can be stretched to a silky consistency. 4, other: some people will feel breast pain, temper tantrums, emotional depression and so on. The feelings that occur during ovulation vary from person to person, and having the above mentioned feelings does not mean that ovulation is taking place. In addition to causing infertility, ovulation disorders can also lead to menstrual disorders, amenorrhea, hirsutism, obesity and other symptoms. In addition, if ovulation does not occur for a long time, sex hormone metabolism will be disturbed and the endometrium will be overproliferated without the counteracting effect of cyclic progesterone, i.e., no cyclic shedding and bleeding will occur, which may lead to endometrial cancer. Therefore, those with ovulation disorders should be given enough attention and undergo active examination and treatment. Treatment of ovulation disorders Ultrasound monitoring of ovulation and guidance of intercourse is one of the important methods for the treatment of ovulation disorders infertility. In other words, after the application of ovulation-promoting drugs or during the natural menstrual cycle, ultrasound is taken to detect the follicles. Starting from about day 10 of the menstrual cycle (the exact time can depend on individual menstrual cycle), the emergence and development of the dominant follicle will be dynamically observed under ultrasound monitoring until ovulation, and coitus will be guided. If pregnancy occurs, care should be taken to strengthen the luteal function to prevent miscarriage. In addition, if the formation of a dominant follicle is monitored by ultrasound and meets the criteria for a mature follicle (maximum follicle diameter >18mm, translucency, clear borders, etc.) and the follicle persists without disappearing or shrinking significantly (follicular retention type) or continues to increase in size (30-45mm, follicles continue to grow large), and no free fluid appears in the rectal trap of the uterus, the possibility of unruptured follicular luteinization syndrome should be considered. Treatment varies from person to person and often focuses on ovulation induction, but if follicle non-rupture still occurs after several months of repeated use of ovulation-promoting drugs, surgery or IVF may be required.
