About the Follicle Tracking Scan
A follicle tracking scan checks the size of the ovarian follicles during a given time in your cycle. A number of follicle tracking scans are needed to check the growth of these follicles and may help to determine if you are ovulating and producing eggs. The scan also checks the womb lining for thickness.
Our follicle tracking scan can be used to monitor your fertility treatment and confirm the best time to conceive. When your eggs are nearing maturity, it helps to know when the ovulation occurs and helps the fertility clinic predict the best time for IVF clinicians to perform an egg pick-up.
The scans should be timed according to your menstrual cycle as this will determine when you are most likely to ovulate. The number of scans will vary from person to person.
Typically the first follicle tracking scan is performed on day 8 of your menstrual cycle, however, this may vary if you are having fertility treatment and timed according to your fertility clinic requirements. Further scans will be conducted at specific intervals, usually 1-3 days, to track the size of your follicles.
Tip – It may be useful to have our fertility scan prior to follicle tracking scans which is usually performed by the 5th day of your menstrual cycle.
Objective of the Follicle Tracking Scan
The follicle tracking scan or Follicular tracking is the simplest form of assisted conception. There is no stimulation of the ovaries with any drugs or medicines and it is the most natural form of assisted conception. The pregnancy rate for this type of assisted conception is around 10%.
The ultrasound scan allows us to see what is happening inside your ovaries. The scan will check the size of the largest follicles or eggs in the ovaries to check that your eggs are maturing properly. This can help provide information about when you may ovulate. The scan can also be used to check for signs to see whether your ovary has ovulated or not depending on when the scan is performed.
What can the Follicle Tracking Scan detect?
The scans provide useful information which could help determine the time when you will be most fertile.

Benefits of having the Follicle Tracking Scan
A follicle-tracking scan provides many benefits, especially among women with fertility difficulties. The scan optimises the chance of natural fertilisation or intrauterine insemination (IUI).
The scan is also vital in assisting fertility treatment. It can be used to track follicle development and collection of eggs.
The scan also helps your clinician survey the endometrium and ovaries.
You can choose to have your scan at a private follicular tracking scan clinic. Some of the benefits of private follicular tracking in London include the following;
Private scan clinics in London invest in the latest technology and scan equipment to provide the best services and results. The clinics also have the best sonographers and supporting staff to ensure you get the best experience and produce reliable and clear results that can help your healthcare provider make the best decisions for the best results.
Follicle tracking mainly focuses on fertility, so the scans must be done within a short window and the results delivered quickly to allow for quick and efficient interventions. Most private scans allow you to make appointments on short notice and deliver the results shortly after the test. Considering that time is a factor with some of these scans, a private scan clinic might be the best option.
Some follicular tracking scans are done transvaginally, which can be uncomfortable for some women. Private scan clinics offer a specialised and personalised experience that helps to make the experience more comfortable and predictable for the patient.
A private follicular tracking scan is more convenient than going to a public facility. In most cases, the waiting times are long in the NHS, however with private scans, the timelines are much shorter. You can have your scan done in a few hours. Our private scan clinic are open on the weekends, which makes them more flexible and convenient for people who want to take the scan on the weekend.
Why do I need a Follicle Tracking Scan
You may be asked to have a follicle tracking scan for several reasons including;
- Find out when you are ovulating so you can time your sexual activity to maximise your chances of conceiving naturally.
- Check that your eggs are maturing and being released for fertilisation to rule out certain fertility problems.
- Check to see when your eggs are ready to be harvested if you are undergoing IVF treatment.
Tracking timed intercourse
Follicles can be tracked in a natural cycle: Find out when you are ovulating so you can time your sexual activity to maximise your chances of conceiving naturally. When a leading follicle is seen, then intercourse may be appropriately timed. In some instances, your doctor or fertility clinic may provide drugs to induce ovulation.
Check that your eggs are maturing and being released for fertilisation to rule out certain fertility problems.
Tracking for IVF
In most IVF treatments, your ovaries will be artificially stimulated with follicle-stimulating hormone (FSH), which produces multiple mature follicles, which are then harvested after the administration of luteinising hormone.
In such instances, your follicular development is followed closely with 2 to 4 ultrasound scans. The timing of your egg collection is based on the ultrasound and any blood test results.
A follicular scan is needed for women who do not ovulate, those who are unsure when they ovulate, women prescribed fertility medication and couples who are not conceiving after 6-12 months of trying. The scan can check the size of the follicles and to see when your eggs are ready to be harvested.
What does the Follicle Tracking Scan involve?
During the scan, you will be asked to uncover the area being scanned, hence we advise to wear suitable loose clothing and a small amount of ultrasound gel will be placed over your skin.
An ultrasound camera (‘probe’) will then be placed on top and moved along and around the area. This results in a picture appearing on the ultrasound monitor and patient TV which will be translated by the clinical specialist/ medical practitioner.
The ultrasound scan itself usually lasts around 10-15 minutes and is pain-free. At the end of the scan, a verbal summary of the results will be provided, as well as your opportunity to ask any questions.
How do I prepare*
An internal (Transvaginal) scan is recommended or may be mandatory for specific services instead of the scan over your tummy as it often provides greater detail and better information, please ask our customer care team for more information.
For internal scans you do not need to have a full bladder and will be asked to empty your bladder if full. Also please do arrive in clothing that can allow easy and comfortable access to your pelvic area.
- For scans over your tummy (Transabdominal) then we recommend you arrive with a comfortably full bladder. Please drink 0.5 litres of clear fluid approximately 30 minutes or so before your scheduled appointment and kindly try your best not to empty your bladder before the examination.

Follicle Tracking Scan FAQ's
What is a follicle?
A follicle is a small sac filled with fluid found in the ovaries. Each follicle is an immature egg which grows and increases the sizes of the follicle as it grows. The egg is released when the follicle reaches the optimum size, which is when ovulation occurs. The number of follicles in the ovaries present tells much about the state of fertility.
How successful is follicle tracking?
Follicle tracking is a technique that gives couples a great chance of achieving pregnancy. The tracking helps to determine when women are ovulating. For a woman to ovulate, the egg must be released from a follicle and travel along the fallopian tube.
Studies suggest that follicle tracking is only 10% successful. The success rate also varies from patient to patient and depends on many variables, including hormone levels and other underlying fertility issues.
Is follicle tracking painful?
Follicle tracking is a painless procedure. However, when done transvaginally, it can be uncomfortable and feels like something pressing against your cervix. The discomfort might also vary depending on the angle of the small plastic probe inserted in the vagina.
When should a follicle scan be done?
A follicle scan should be done several times during a woman’s menstrual cycle. It is usually done from 8-20 days.
What is the follicle size for ovulation?
The follicle size for ovulation varies but should have an average diameter of 18 to 24mm. However, the follicle’s growth doesn’t always mean a mature egg.
