Follicular Tracking Ultrasound Scan (Transvaginal Scan) - Private Fertility Scan



What is follicular tracking? 

Follicular tracking means that you are monitoring the number and size of your follicles during your cycle. Follicular tracking is an ultrasound transvaginal scan being used to evaluate the number and size of the ovarian follicles. Follicular tracking can be used to monitor your fertility and confirm the best time to conceive.

Follicular tracking is also being used to track the number and size of the ovarian follicles during IVF treatment.


Why is the follicular tracking scan being done?

  • Having IVF treatment and your fertility doctor wants to monitor the number and the size of the follicles and endometrial thickness.
  • You have regular cycles and have been trying to conceive for several months without success.
  • You have irregular cycles and want help to determine the best time to conceive.
  • You are planning to get pregnant and you want to know that you are ovulating.


What is included with this follicular ultrasound scan?

  • Ultrasound report with information about the number and the size of the follicles and endometrial thickness. 


How is the follicular tracking scan being done?

The follicular tracking scan is the same as the transvaginal ultrasound scan which means that a thin ultrasound probe is inserted in the vagina so the sonographer can have a clear view of your uterus, the lining of the uterus and your ovaries. The procedure for this can is the same as the pelvic ultrasound scan.

You will be asked to lie on your back on the couch and a towel will be provided to cover yourself. A special lubricated probe will be inserted into the vagina and will be moved to different directions to obtain the best images. This scan might feel a bit uncomfortable, but should not be painful.


How much does follicle tracking costs?

Price: £164 or £375 for series of 3 scans.

You should be able to resume your normal activities immediately after the scan.


What is a follicle?

A follicle is a small fluid-filled sac inside the ovaries containing immature eggs. The size and number of the follicles is an indication of your fertility and varies between women.


What is the follicle size for ovulation?

For ovulation to occur the follicle needs to reach approximately between 18-24 mm.


When to do follicular tracking?

As the name suggests, the follicular tracking tracks the size and the number of your ovaries throughout your cycle, so it requires 1 to 3 scans commenting from day 7 – 9 of the first day of your period.

If you are having IVF treatment, your fertility specialist will advise you about the timings of your ultrasound scans.
