                                            What’s involved in a diagnostic ultrasound scan.
If you’re starting fertility investigations, one of the first steps is a diagnostic ultrasound scan. This scan usually takes place between day 2 and day 8 of your cycle.
When you arrive at the clinic, you’ll check in at reception and take a seat in the waiting area. When it’s time for your appointment, the nurse will call you in, introduce themselves, and explain what will happen before starting the scan.
The scan is performed using a small va**nal ultrasound probe, which is gently inserted into the va**na. This gives a clear view of your ovaries, womb, and pelvic area. The procedure usually takes around 20 minutes and is generally comfortable for most patients.
During the scan, the nurse will check:
▪️The appearance and size of your ovaries
▪️The number of follicles (tiny fluid-filled sacs that may contain eggs)
▪️The thickness and condition of the womb lining
▪️Any signs of cysts or fibroids
After the scan, a report is sent to your Merrion Fertility Clinic doctor. They’ll go through the results with you at your consultation, alongside your AMH (Anti-Müllerian Hormone) test results, to assess your ovarian reserve.
