Follicular Monitoring

FOLLICULAR MONITORING.

Follicular monitoring is the process of serial ultrasonic monitoring of the ovarian follicles used to identify the maturation status of eggs. It is used for assessing the size of the follicle that supports the growing egg and for determining the thickness of the uterine lining.

The average diameter of the dominant follicle should be 20 to 22 mm this is the only marker that can predict ovulation with ease.

Once the ovulation occurs the egg remains for 24 to 36 hours only, So it is important to know when ovulation occurred by follicular monitoring so that either IUI is planned for natural cycle conception is planned.

Follicular monitoring should be started from the seven or eight days of the menstrual cycle but in some cases, we can start from the sixth day of the cycle also, Normally follicle grows at a rate of 2 to 3 mm per day in a stimulated cycle.

Follicular monitoring is also needed for monitoring the growing eggs in IVF cycle also.
