Commonly used ovulation-promoting drugs include clomiphene, letrozole, HMG, human chorionic gonadotropin, etc. If a woman has ovulation disorders, she will experience infertility, menstrual disorders, amenorrhea, etc. The causes of ovulation disorders are complex and different drugs should be chosen for different reasons. HMG is also called postmenopausal gonadotropin and is mainly used in patients with low luteinizing hormone and follicular estrogen, and ovulation must be monitored by ultrasound during administration. HMG is similar in structure to luteinizing hormone and is often used in patients who do not ovulate after follicular maturation because luteinizing hormone does not reach its peak. Therefore, a thorough checkup, especially a sex hormone level test, should be performed before using ovulation-promoting drugs to improve the dosage and method of administration.
