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 in different directions to obtain the best images. This scan might feel a bit uncomfortable, but should not be painful.

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 vary between women.


What is the follicle size for ovulation?

For ovulation to occur, the follicle needs to reach approximately 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.
