8 Must-Know Facts About Follicular Study - Diwya-Vatsaly-Mamta-IVF-Patna

Are you trying to conceive? Have you heard of the term “follicular study”? If you’re wondering what it means and why it’s important, you’ve come to the right place!

As an IVF specialist with over 20 years of experience, I’m here to guide you through 8 essential facts about follicular study. From its meaning to the procedure, monitoring, report evaluation, and more, you’ll gain a comprehensive understanding of this vital aspect of fertility treatment. So, let’s dive in to unlock all the follicular study facts.

Follicular Study Meaning

A follicular study is a medical test that checks how ovarian follicles grow and change throughout a woman’s menstrual cycle. The test uses ultrasound to see the ovaries and measure the size of the developing follicles. These follicles hold the eggs that will be released at the time of ovulation. 

Follicular Procedure

The follicular study procedure typically takes several weeks to complete. It may need to be repeated in subsequent cycles if pregnancy does not occur. Here are the typical steps involved in a follicular study:

Baseline ultrasound

A baseline ultrasound is usually done on day 2 or 3 of the menstrual cycle to find out how big the ovaries and follicles are at the beginning of the cycle.

Follicle monitoring

IVF specialist schedules ultrasounds every 2-3 days from day 7 to 10 of the patient’s menstrual cycle. However, it depends on the individual case. The physician measures the size and number of follicles and checks the thickness of the uterus lining during each ultrasound.

Hormone monitoring

You may need to undergo some blood tests to measure hormone levels, such as estradiol and luteinizing hormone (LH). It will help to predict ovulation and confirm the maturity of the follicles.

Ovulation prediction

Based on the size and growth of the follicles, the doctor can predict when ovulation is likely to occur. The doctor may advise the patient to have sexual intercourse or undergo fertility treatments. It may include intrauterine insemination (IUI) treatments.

Follow-up ultrasound

The doctor may perform a final ultrasound around day 21 of the menstrual cycle. This is done to confirm ovulation and evaluate the corpus luteum, which is a structure that forms in the ovary after ovulation and secretes hormones to support pregnancy.

Understanding Follicular Monitoring

Why is follicular monitoring done?

Doctors perform follicular monitoring to monitor the growth and development of ovarian follicles during a woman’s menstrual cycle. The primary objective is to determine the optimal time for sexual intercourse or intrauterine insemination (IUI) in couples who are trying to conceive.

Doctors use follicular monitoring to predict when ovulation is likely to occur by monitoring the size and development of the follicles and advising couples on the best time to have intercourse or undergo fertility treatments. This approach can increase the chances of conception and improve the success rate of fertility treatments.

When is follicular monitoring necessary?

Follicular monitoring is necessary when there are concerns about fertility or reproductive health. It can help diagnose and treat a variety of conditions that may be affecting a woman’s ability to conceive.

Follicular monitoring may be necessary for the following situations:

Infertility: Couples who have been trying to conceive for a year or more without success may undergo follicular monitoring to determine the optimal time for sexual intercourse or intrauterine insemination (IUI).

Fertility treatments: Follicular monitoring is essential to fertility treatments such as in-vitro fertilization (IVF) or intrauterine insemination (IUI) to determine the best timing for egg retrieval or insemination.

Polycystic ovary syndrome (PCOS): It can help diagnose and monitor PCOS, a condition that causes hormonal imbalances and disrupts ovulation.

Unexplained infertility: If a couple has been trying to conceive for a long time without any obvious medical explanation, follicular monitoring can help identify potential issues with ovulation or other factors that may be affecting fertility.

Ovarian cysts or tumours: Follicular monitoring can help monitor the size and growth of cysts or tumours on the ovaries, which may require surgery or other interventions.

Hormonal imbalances: It can help identify hormonal imbalances that may be affecting fertility, such as high levels of luteinizing hormone (LH) or low levels of follicle-stimulating hormone (FSH).

Follicular Study Report and Evaluation

How is the Follicular Study Evaluated?

A follicular study is evaluated based on several key factors, including the size and number of follicles, the thickness of the endometrial lining, and the timing of ovulation. Doctors may also consider other factors, such as the presence of cysts or tumours, hormonal imbalances, or other reproductive disorders.

The evaluation process involves reviewing the results of multiple ultrasound scans conducted over the course of several days, as well as other diagnostic tests and medical history. Based on this evaluation, doctors can provide recommendations for fertility treatments or other interventions as needed.

Follicular study normal report

It means that follicles are growing and developing at the expected rate, and there are no signs of any abnormalities or irregularities. A normal report includes information about the size and number of follicles, the thickness of the endometrial lining, and the predicted time of ovulation.

Can Follicular Study Confirm Pregnancy?

While a follicular study can provide important information about the timing of ovulation and the likelihood of conception, it cannot confirm pregnancy. Confirmation of pregnancy can only be done through a pregnancy test or other diagnostic procedures.

Follicle size for pregnancy

The ideal follicle size for pregnancy varies depending on the stage of the menstrual cycle and the individual woman. Generally, a mature follicle ready to release an egg during ovulation should be between 18 and 30 millimeters in diameter.

However, it’s important to note that simply having a follicle of the right size does not guarantee pregnancy, as many other factors can affect fertility. Additionally, smaller follicles can still result in pregnancy, particularly using assisted reproductive technologies like in vitro fertilization (IVF).

Ultimately, the best way to determine whether a follicle is the right size for pregnancy is through regular monitoring and consultation with a fertility specialist.

How much time does it take to undergo a follicle scan?

The time to undergo a follicle scan can vary depending on the individual and the healthcare provider. Generally, a single ultrasound session for follicular monitoring can take around 15-30 minutes to complete. However, multiple ultrasound sessions may be required during a single menstrual cycle, and the frequency and timing of these sessions may vary depending on the individual case.

Follicular study cost

In India, the cost of a follicular study can vary depending on the location, healthcare provider, and the specific tests or procedures involved. Generally, a baseline ultrasound for follicular study can cost anywhere between INR 400 to INR 1500.

The cost of each subsequent ultrasound for follicular monitoring can range from INR 600 to INR 3000. At Diwya Vatsalya Mamta IVF, we have put the cost to a minimum so that it can be affordable to all. The total cost of a follicular study may also depend on additional factors like blood tests and medication costs. It’s best to consult with a healthcare provider or fertility specialist to get a more accurate estimate of the cost based on individual circumstances.
