What is a Follicular Study? Process, Benefits & Who Needs It
During your fertility journey, you may come across several tests and treatment stages. Follicular study is one of the first and most important steps in the IVF and IUI treatment processes. It may seem daunting at first, but learning about its purpose and process will hopefully make you feel more at ease and understand why it is necessary.
What is a Follicular Study?
Follicles are tiny, fluid-filled sacs inside a woman’s ovaries that contain eggs. Every month, during her menstrual cycle, these sacs grow as the eggs inside mature. During ovulation, the dominant follicle releases a single egg.
So what is a follicular study? A follicular study is a series of transvaginal ultrasounds that monitor the growth of the follicles from the beginning of the menstrual cycle up until the point of ovulation.
Since an egg survives for only about 24 hours after ovulation, accurately tracking follicular development is extremely important in timing conception efforts. It helps in understanding a woman’s ovulation cycle and is crucial for natural conception planning and assisted reproductive technologies like IVF or IUI.
When Is a Follicular Study Recommended?
All women looking to start the IVF or IUI process typically undergo a follicular study. We also recommend it to women who meet the following criteria:
- You’re under 35 years of age and have been trying to conceive for over 1 year
- You’re over 35 and have been trying for over 6 months
- Have PCOS/PCOD
- Have anovulatory cycles
- Are taking medication like FSH or Clomid
- May have ovulation issues
- Are undergoing ovarian stimulation
- Have had miscarriages due to unknown reasons
What is a Follicular Study? Step-By-Step Procedure
In a follicle scan, a sonographer inserts a thin ultrasound probe in the vaginal canal to examine the ovaries and the growth of the follicles. This helps them understand how the egg is developing inside the follicle. The most common and accurate method for follicular studies is a transvaginal ultrasound.
Baseline Scan
The first step is the baseline scan, and it is usually performed on the second or third day of the menstrual cycle. Each visit will take about 20-30 minutes. You will be required to empty your bladder first, as a full bladder can interfere with the results.
You will lie down on your back with your legs raised and bent. The ultrasonologist will insert a thin, wand-like probe into your vaginal canal to capture images of the ovaries and follicles. This part will only take about 5-10 minutes.
Monitoring Phase
You will continue to receive follicular study scans approximately every 1 to 3 days. These visits will allow the doctor to monitor the growth of your follicles as the menstrual cycle progresses and assess the thickness of the uterine lining.
Your doctors continue to monitor follicle growth until your dominant follicle reaches an optimum size and ruptures during ovulation. This helps us determine the timing of your ovulation.
What are the Benefits of Follicular Monitoring?
Getting a follicular scan or folliculometry is a painless procedure that can be carried out for various reasons. Here are some situations in which follicular monitoring is considered:
Response To Medication
If you’re undergoing fertility treatment, follicular studies can help doctors assess how well your ovaries are responding to your current medication and adjust the dosage and type of drugs you’ll require. Using the appropriate dose of fertility medication will boost your chances of conception.
Diagnosing Irregularities
It can help diagnose issues and irregularities with the menstrual cycle, like the absence of ovulation (anovulation) or conditions like OHSS and luteal phase deficiency. These problems may unknowingly have been the cause of your infertility.
Ovulation Tracking
A follicular study can help accurately predict the time of ovulation. This is essential in treatments like timed intercourse and in properly timing fertility treatments like IVF and IUI for the maximum chances of conception.
PCOS Diagnosis
A follicular scan is one of the key tools used to test for and diagnose PCOS. It can help identify the presence of cysts on the ovaries (polycystic ovarian morphology), which is an important indicator of PCOS.
Optimizing Fertility Treatments
By identifying the time of ovulation, a follicular study can help doctors decide on the best time for different procedures in IUI and IVF treatment.
What is a Follicular Study?
A follicular study is an important part of the fertility treatment process. Without detecting ovulation accurately, many of the other steps in the treatment process will have little to no effect. For example, knowing exactly when ovulation happens helps us guide couples on the best time to try for pregnancy or plan fertility treatments—giving them a better chance of success.
