A Follicular scan looks at the ovaries and uterus internally using a sterile (clean) transducer paying particular attention to the follicles within the ovaries. A follicle is a fluid area in which the eggs grow. The follicle increases in size as the egg grows. Follicular tracking involves scanning the ovaries regularly during your menstrual cycle and observing the follicles as they increase in size. Ultrasound uses high-frequency sound waves, which pass through the skin and are reflected by the internal organs to create a picture on a screen with the help of a computer. These pictures are then interpreted by the Radiologist/Radiographer/Sonographer/Gynecologist.
Follicular Scans can be done several times usually between the 9th and 25th day of the menstrual cycle. It is a painless procedure and helps the doctor to see the follicles within the ovary.
During a woman’s normal menstrual cycle, it is recommended to have 4-6 scans. This is done to ensure the exact moment when ovulation has occurred, which can be seen on the scan when the follicle disappears from the picture or the follicle walls become collapsed or irregular.
Scans are easy to perform, taking between 5-10 minutes each. Patients receive a report from their doctor detailing the findings.
Ultrasound has been around for the last 30 years and there are no known side effects. It does not involve the use of x-rays and it is a simple, painless procedure. This scan does not have any effect on fertility.
