Clomiphene citrate capsules can promote ovulation in clinical practice, and most of them take about 3-6 months to promote ovulation successfully. The success rate of ovulation promotion is relatively high, but the pregnancy rate is not as high as that of ovulation promotion. It is recommended to monitor ovulation through ultrasound during the process of ovulation promotion and to eat more estrogen-containing food if necessary to make the cervical mucus become relatively thin, which will facilitate the passage of sperm and achieve pregnancy in clinical practice.
