Normally, only one side of both ovaries will have a dominant follicle in a month, and it has nothing to do with having 8 or 10 follicles in both ovaries, depending on whether there is a dominant follicle or not. If there are 8-10 follicles in both ovaries during the ultrasound examination, there may be a possibility of polycystic ovaries. Because normally there are not so many, there are less than 8 or even 5-6 small follicles, and only 1 follicle develops into a dominant follicle. It is recommended to carry out endocrine hormone tests to exclude the presence of increased testosterone, and whether the ratio between ovulation stimulating hormone and luteinizing hormone is more than 2.5, if it is more than this ratio, it means that polycystic ovaries are occurring. Monitoring for the presence of dominant follicles and thickening of the ovarian cortex can also determine the presence of polycystic ovaries.
