Ovulation promotion refers to the application of ovulation-promoting drugs to make the follicles mature and ovulate. In a normal menstrual cycle, estrogen and progesterone work to promote follicle growth and maturation to natural ovulation. Ovulation promotion can be performed when the follicles are not growing properly due to insufficient hormone levels or other factors. In some women with infertility, it may be due to a disease such as polycystic ovary syndrome that prevents the eggs from being expelled normally to unite with sperm to form a fertilized egg. Currently, there are many types of ovulation-promoting drugs in clinical use, including Chinese and Western medicines. Western medicines mainly regulate the hypothalamic-pituitary-ovarian axis to promote follicular discharge, such as clomiphene citrate capsules, letrozole, and intramuscular injection of human chorionic gonadotropin. Ovulation promotion can also be harmful and may lead to abnormal ovulation, ovarian hyperstimulation syndrome, and even increase the risk of tumors. Women who undergo ovulation promotion should do so under the guidance of a doctor. Before receiving ovulation promotion, it is necessary to clarify the basic health condition, and after receiving ovulation promotion, it is recommended to monitor ovulation by ultrasound after the end of the physiological period. If lower abdominal pain occurs during the ovulation promotion period, it may be due to ovarian hyperstimulation and it is recommended to go to the hospital as soon as possible for appropriate treatment. In addition, patients are advised to maintain a good routine and a happy mood in their daily life, and to eat beef and fish to ensure nutritional supply.
