During ovulation promotion, it is important to pay attention to the following matters: first, be sure to monitor the growth of follicles by ultrasound to understand the growth rate of follicles and, in the case of follicles reaching dominance, intramuscular injections of chorionic gonadotropin can be given to promote the rupture of follicles and the discharge of eggs. Secondly, because ovulation-promoting drugs, clinically, may cause over-stimulation of the ovaries, it is important to observe whether you experience lower abdominal distention and pain and a decrease in urine output. If this happens, go to the hospital in time for examination and, if necessary, treatment to avoid the harm caused by ovarian hyperstimulation. Thirdly, it is important to note that because ovulation medication may cause premature ovarian failure, it is important to pay attention to the dosage of ovulation medication in bed, so that it is not too large.
