Common questions about follicle tracking

Tracking your ovulation cycle? Here's what you need to know.

  • When do I start follicle tracking scans?

    Start from day 5 to 8 of your cycle (day 1 = first day of period). For shorter cycles, start earlier; for longer cycles, start later. We’ll advise based on your cycle length when you book.

  • Do I need follicle tracking if I'm having IUI or IVF?

    For IUI, yes—it’s essential to time insemination correctly. For IVF, your clinic will require monitoring follicles as part of your treatment cycle. 

  • Is this the same as an ovulation test?

    No—follicle tracking is more precise. Ovulation tests detect the LH hormone surge (which happens before ovulation), but they don’t confirm follicle maturity or actual ovulation. Ultrasound directly visualizes follicle size and growth.

  • Can follicle tracking help me conceive naturally?

    Yes. By identifying your exact ovulation timing, you can time intercourse for maximum conception chances. It’s especially helpful if you have irregular cycles or aren’t sure when you ovulate.

  • What size follicle indicates ovulation?

    Mature follicles are usually 18-24mm. Once a follicle reaches this size, ovulation typically occurs within 24-48 hours. We’ll advise when to time intercourse or trigger ovulation medication.

  • How many scans will I need?

    Typically 3 scans over 7-10 days. The first scan checks baseline, subsequent scans track growth until follicles are mature. Timing between scans depends on follicle size and growth rate.

  • I’ve visited Flowan a few times over the last few years for various reasons and every time the service and care is outstanding. There are clinics much closer to me I could opt for but travel out of my way to Flowan simply for the service.
