What is Follicular Monitoring?

Follicular Monitoring, also known as Follicular Study or Folliculometry, it’s a sonography test.

When a female patient approaches us with infertility, our first step is determining her ovulation health.

Follicular Monitoring can be very helpful in this process. There are two ways to perform this test. Either it can be done abdominally, or it can be done from inside via the vagina (Transvaginal Sonography).

We start the Follicular Monitoring test just after the periods end until the follicles reach the size of 20 mm.

After that, we also perform Sonography to study the ovulation process.

What is the purpose of Follicular Monitoring?

The follicle growth cycle starts just after the period, and it ovulates on the 14th or 15th day (for a regular 28-day cycle), the 9th or 10th day (for a shorter cycle) and the 18th or 19th day(for longer cycles).

The core idea behind the Follicular Monitoring test is to determine the exact day of ovulation.

Why?

Because your egg’s life is too short. It survives only for 24 hours.

So if you are planning for a pregnancy, you must know when your egg is ovulating. Performing natural intercourse during this period ensures the maximum possibility of success.

So, Follicular Monitoring is done, for all patients, whether they are looking for IVF, IUI or Natural process.

When is the test conducted?

  • For Natural Cycle :

If you are trying naturally, your doctor will call you on the second or third day of your period.

On this day, the doctor will perform baseline sonography. Baseline sonography is very important.

During this Sonography, we check the remnant follicles or cysts from the previous period in your ovary. Along with that, we also check to ensure whether your endometrium has cleared properly.

We call patients back on the 9th or 10th day after the baseline sonography.

At this stage, we measure the size of the follicle’s size.

If you are trying Naturally, our doctors don’t recommend injections. But if you are taking some basic treatment, we give HCG injection when your follicle size becomes 18 to 20 mm.

  • For IUI Treatment : 

If you are taking IUI treatment, doctors will offer you medications for the creation of the eggs after the baseline test.

These can either be in the form of tablets or injections. Your Follicular Monitoring will start from the 8th or 9th day and will continue till it reaches the size of 18 to 20 mm.

Then you will get an HCG injection. After 36 to 40 hours, your IUI will be planned.

Once the doctor confirms your ovulation after the Sonography, they move towards the next step.

  • For IVF Treatment : 

Follicular Monitoring is necessary for IVF treatment too.

In fact, during the IVF treatment, Follicular Monitoring is performed more frequently.

The doctor performs Sonography on the 2nd or 3rd of the period. Based on the test, they decide your dosage.

Then you are called on the 5th day when the injection’s dose is altered based on the size of your follicle’s size. That’s the reason why Sonography is more frequent in IVF.

Injections will continue until your follicles reach 18 to 20 mm. Once follicle size reaches 18 to 20 mm, the doctor will give you an HCG injection.

After 36 to 40 hours of this injection, doctors will plan the ovum pickup process.
