The follicle-breaking injection refers to human chorionic gonadotropin, which is usually excreted in 9 days, but there may be cases of incomplete excretion in patients with liver or kidney insufficiency. The main function of human chorionic gonadotropin is to increase the luteinizing hormone in the body, which leads to the rupture of the follicle and then ovulation. When the follicle develops normally during ovulation, but fails to rupture and ovulate, it is necessary to break the egg injection, which can be metabolized completely in about 3 days under normal circumstances. However, if the patient has hepatic or renal dysfunction, the excretion of this drug may be prolonged and may not be completed in 9 days. When using this drug, there may be adverse reactions such as increased ovarian size, follicular hyperstimulation, gastrointestinal discomfort, and the current contraindications for this drug are unclear. Be careful to use the drug under the supervision of a doctor. If there is significant discomfort after breaking the follicular injection, it is necessary to pay attention to timely medical attention and intervene in a standardized way under the guidance of a doctor.
