The presence of multiple follicles in both ovaries is suggested during ultrasound follicle monitoring. If there are 7-8 follicles, this is normal because 7-8 is the basal follicle and it does not necessarily mean that it will grow to a dominant follicle, as long as there is one dominant follicle a month, it is possible to prepare for pregnancy. However, if there are more than 10 follicles bilaterally, it will indicate polycystic ovary syndrome. Because polycystic ovary syndrome is an endocrine hormone disorder, the absence of dominant follicles can affect pregnancy. It is recommended to combine endocrine hormones and check endocrine hormones on the 2nd-5th day of menstruation on an empty stomach to see if androgens are high. If polycystic ovary syndrome is confirmed, oral treatment with DY-35 is needed for 3 months to help lower the testosterone value. In the future, if you are preparing for pregnancy, you need to perform ovulation promotion, which will help the success of ovulation promotion and pregnancy.
