What Is Follicular
Monitoring?
SERIAL ULTRASONIC MONITORING OF THE OVARIAN FOLLICLES TO
FOLLOW GROWTH OF EGGS IS TERMED FOLLICULAR MONITORING.
What are ovarian
follicles?
Ovarian follicles are the basic units of female reproductive
biology. Each of them contains a single oocyte (egg).
What is the best size
of follicles to ovulate?
Follicles are minute in size around menstrual days. Slowly
they grow and mature. A mature follicle of size more than 16mm is ready to
ovulate (release egg)
What is follicular
study test?
Follicular study is charting the follicular growth after the
menstruation. Follicular monitoring is completed at ovulation.
At what size does the
follicle rupture?
Follicles mature and rupture at 18 to 20 mm size. Ovulation
happen around 12th to 18th day of Cycle.
What is done in
follicular test?
Assessment of the follicular maturity and endometrial
receptivity is done by ultrasound follicular testing.
What do we see in
follicular monitoring?
We can measure the follicle size and endometrium thickness
by ultrasound in follicular monitoring.
How does follicular
measurements using a computerized 3D ultrasound system help?
In 3D ultrasound,
follicular volume can be measured. It also gives idea about blood flow to the
tissue. Ovarian function may be measured by gynaecologic ultrasonography of
follicular volume.
Comparison of
transvaginal and transabdominal ultrasound – Which is better for follicular
study?
Transvaginal ultrasound has advantages of better clarity
about the uterus and ovaries.
How to prepare for a follicular tracking ultrasound?
For follicular tracking through
transvaginal ultrasound patient is asked to empty urine just before the test.
She does not need to come in empty stomach.

What to expect from a follicular tracking ultrasound?
Follicular monitoring tells us
about the time of follicular growth and release of egg. This helps in
administering medications in time.
How long does a follicular tracking ultrasound examination last?
Usually a transvaginal ultrasound
is completed within 15-20 minutes.
Follicle monitoring for PCOS – how it is different?
In PCOS there are more number of
follicles and high chance of ovarian hyperstimulation.
Why hormone tests required during follicular monitoring?
Sometimes hormone tests are
combined with follicular monitoring to have a better idea about quality of egg.
When should follicular study start?
Ideally follicular study should
start from day day 3 of the cycle, to assess a baseline size, as well as
exclude if any cyst remains from previous cycle.
What is the role of
AMH in follicular monitoring?
Serum AMH measurements are a better predictor of the number
of early antral follicles than conventional hormone measurements. Patients with
AMH of 3- 5 are expected to grow follicles well.

What is a follicular
cyst?
Sometimes the maturing follicle ( dominant follicle ) grows
at a good pace but fails to ovulate, and later becomes a cyst filled with fluid
only.
Why follicles do not
rupture?
At times follicles form cysts and don’t rupture. This
happens frequently in elderly patients or patients with low ovarian capacity.
It may be due to poor quality of oocyte.
