If the follicles do not grow after the ovulation injection, it is possible that the estrogen level in the body is low, causing the phenomenon of abnormal follicle development. It is recommended to go to the obstetrics and gynecology department of the hospital in time and cooperate with the doctor to inject urinary chorionic gonadotropin treatment, which usually takes three months as a course of treatment. The success rate of artificial insemination is higher only when the ovaries are mature and the eggs are fertilized with sperm, and the fertilized eggs develop into blastocysts and are transferred. If the follicles are not mature, even if the eggs are released, the eggs will not be mature and the sperm will not unite to form a fertilized egg, and after the embryonic tissue is developed and transferred, it will be easy to have a miscarriage or stillbirth. The development of follicles requires a certain physiological environment, so you need to cooperate with your doctor for endocrine regulation, and only after normal regulation is conducive to follicle development.
