What This Scan Includes
Serial follicle size monitoring
Endometrial thickness measurement
Ovulation timing prediction
Multiple follicle assessment
Optimal conception window identification
Immediate results and guidance
When Should I Book?
Day 8-10
Initial scan to assess baseline follicle development and endometrial response.
Day 12-14
Follow-up scan to confirm dominant follicle maturity and predict ovulation timing.
Additional Scans
Further scans may be needed based on follicle growth rate and treatment protocol.
Recommended: Start tracking on day 8-10 of your cycle (day 1 being the first day of your period). Serial scans every 2-3 days allow precise monitoring of follicle growth and optimal timing prediction.

Common Questions
How many scans will I need?
Most women need 2-3 scans per cycle. The first scan is usually on day 8-10, with follow-up scans every 2-3 days until a mature follicle is detected. Your sonographer will advise on the optimal timing for subsequent scans based on your individual response.
What size follicle is ready for ovulation?
A dominant follicle typically needs to reach 18-24mm before ovulation occurs. At this size, the egg inside is mature and ready for fertilisation. Your sonographer will monitor growth and advise when ovulation is imminent.
Can follicle tracking help with natural conception?
Yes, follicle tracking is valuable for natural conception attempts. It identifies your most fertile window with precision, allowing you to time intercourse optimally. This is particularly helpful if you have irregular cycles or are unsure when you ovulate.
Is follicle tracking uncomfortable?
Follicle tracking uses transvaginal ultrasound, which may cause slight discomfort but should not be painful. The internal probe provides superior imaging of the ovaries and follicles compared to abdominal scanning.
