Follicle 1815 is the ovulation period

Generally speaking, the normal follicle size is about 1815mm. However, this is only a rough reference value, because everyone's physical condition is different, so the normal follicle size will also vary. If a woman's follicles are smaller than 18-15mm, further testing may be needed to determine if there are any problems. If a woman's follicles are larger than 2000mm, special treatment may be needed to ensure the quality of the eggs.

In addition to follicle size, there are other factors that influence when a woman ovulates. For example, women's political, economic, and social circumstances may have an impact on their reproductive health and thus their ovulation periods. In addition, a woman's age can also have an impact on their reproductive health, which can have an impact on when they ovulate.

To sum up, measuring follicle size is an important way to predict a woman’s ovulation period. However, it should be noted that everyone's body is different, so the normal follicle size will also vary. If you have any concerns or questions, please consult your doctor.
