Follicular Tracking Ultrasound Scan (Transvaginal Scan)

Follicle tracking is being used to identify the best time to get pregnant.  Follicular tracking can be used to identify the time of ovulation on women with regular or irregular cycles to determine the best conception time.

Follicular monitoring can also be used during infertility treatment such as in-vitro fertilization (IVF) assessment to determine the best time for the intrauterine insemination. This fertility scan uses ultrasound to  assess ovarian follicles at regular intervals and therefore help the obstetrician to understand when you ovulate and when egg retrieval is best performed. The tracking scans start normally at the 10th day of the cycle.
An ovarian follicle (also known as a Graafian follicle in its mature state) secretes hormones that regulate the menstrual cycle. During the menstrual cycle at least one of the ovarian follicles will become dominant and will release an egg to be fertilised.. After releasing the egg the follicle turns into a corpus luteum.


What is the purpose of this follicle tracking ultrasound?


Reasons for having a follicular tracking scan include:


What is included with this test?



No preparation is required for this follicular scan.


What should I expect during the examination?

This is a transvaginal ultrasound Scan:

After you empty your bladder, you will be asked to remove your trousers/skirt and your underwear. You will lie on the examination couch, cover yourself with the cover provided and a small transducer will be inserted into the vagina.   This internal ultrasound scan is similar to a gynecologic exam but the ultrasonic transducer is however significant smaller than a speculum used in a Pap test.

The transducer will be covered with a protective cover a small amount of gel will be placed on the tip and will be inserted into the vagina. Only a few inches of the transducer will be inserted into the vagina. The transducer will be moved in different directions to obtain the best images. 

What will I experience during and after the follicle tracking scan procedure?


Although the transvaginal/internal examination is usually performed to find a cause for pelvic pain, the sonogram itself should not be painful but you might feel a tiny amount of discomfort and pressure. An internal ultrasound scan is usually more comfortable and better tolerated than a  gynecologic examination.

These ultrasound scan examinations are usually completed within 30 minutes.

After an ultrasound scan examination, you should be able to resume your normal activities immediately.
