Follicular Monitoring

What is Follicular Study?

Follicular study is a procedure in which follicle size is checked on ultrasound from the 2nd day to the 14th or 15th day of periods to track the growth of follicles in the ovaries.

The source page states that a follicle above 20 mm releases a mature egg that can help achieve pregnancy. Growing follicles can be seen with transvaginal ultrasound.

How Follicles Grow and Ovulation Occurs

At each menstrual cycle, a group of around 10 to 15 antral follicles starts growing. These follicles contain an oocyte (female egg) surrounded by cells that nourish it and secrete estrogen.

Step 01

Antral follicles

At every menstrual cycle, approximately 10 to 15 antral follicles begin growing.

Step 02

Follicle growth

The source describes follicle growth at about 2 mm per day.

Step 03

One growing follicle

By the 5th or 6th day of the menstrual cycle, most follicles undergo atresia, and one continues growing.

Step 04

Follicle rupture

The growing follicle is followed with ultrasound until it ruptures, usually after reaching 20 mm.

How Is Follicular Study Done?

Follicular study is performed with transvaginal sonography. Ultrasound images show the follicles and help measure their size as they grow.

Step 01

Ultrasound checks

Follicle size is checked using ultrasound during the menstrual cycle.

Step 02

Study timing

The source says monitoring starts around the 8th to 10th day and continues until the follicle ruptures.

Step 03

Monitor growth

The growing follicle is observed with transvaginal ultrasound; follicles grow about 2 mm per day.

Step 04

Ovulation timing

In women with regular periods, follicle rupture occurs about 14 days before the next expected period.

How many clinic visits are needed?

The source states there are usually 4 to 5 clinic visits in a span of 15 days. If you have undergone follicular study before, fewer visits may be needed because doctors know your follicle growth pattern.
