How large is the egg mature

Under normal circumstances, eggs detected by B-ultrasound are mature when they are 2cm in diameter. Follicles begin to develop, go through early follicular phase, follicular phase, ovulation phase and luteal phase. Follicles before and after ovulation are generally about 2cm in size, but can also be as large as 2.5cm and as small as 1.6cm. For pregnant women, if conditions permit, B-ultrasound monitoring of follicular development begins on the 10th day of the menstrual cycle. Follicles grow from small to about 2cm, mature, and disappear after ovulation. This dynamic process is the normal follicular development process. In addition to using B-ultrasound to monitor ovulation, women can also use basal body temperature, ovulation test paper, etc. to determine whether ovulation is conducive to better pregnancy preparation.
