Fertility scans

Ultrasound scans during fertility treatment

Why a fertility scan?

Around 1 in 8 couples have trouble getting pregnant or successfully carrying a pregnancy. Of these approximately one third is attributed to the mother, one third to the father & one third unexplained.

Many of these couples will successfully receive treatment from their GP or local hospital but some will require more specialist help from a fertility center.

More and more couples are looking for fertility treatment abroad, the advantages of this will be for a variety of reasons such as little or no waiting list for some treatments such as donor eggs, good outcome statistics or reduced cost.

Ultrasound scans are an integral part of fertility treatment for:

endometrial measurement

  • Checking normal pelvic structures (uterus & ovaries)
  • Excluding ovarian cysts or checking for polycystic ovaries
  • Measuring follicle growth and number during treatment cycles
  • Measuring the endometrial thickness (lining)

What can Verulam Clinic offer during your treatment cycle:

How can we help if you are travelling abroad for IVF and donor IVF cycles  

Verulam clinic can perform a scan at the time requested by your clinic, appointments are available most weekdays and on Saturday. The results of the scan can be emailed directly to your overseas clinic or given to you following your appointment.

Ovulation monitoring eg Clomid induced cycle

  • At your first scan we will perform a baseline check to determine the position, size & shape of your womb and to check if there are any fibroids or polyp’s present.
  • To monitor ovulation we look for the development of follicles in the ovary, the egg will be developing within the follicle. On the scan follicles appear as black, circular fluid filled bubbles. These increase in size by 1-2mm per day and are ready for ovulation when the follicle measures between 18-25mm.

    dominant follicle

  • Following ovulation the egg is released and the follicle collapses becoming irregular in shape, this is called the corpus luteum and confirms that ovulation has taken place. Fluid from the follicle can sometimes be seen in the pelvis.
  • During the cycle the lining of the womb, endometrium, changes to receive the fertilize egg, this change can be monitored on the scan. In the lead up to ovulation the endometrium appears as three thin lines and following ovulation it changes becoming brighter.
  • Timing of Scans
  • Timing is very individual and does depend upon the length of the menstrual cycle. Typically in a woman with a 28 day cycle scans will be performed around day 11, 13 & 15. The exact timing will depend upon your cycle length and the stage of follicular development on each scan. The aim is to identify the dominant follicle and to track growth of this follicle and confirm ovulation on the final scan.

Possible problems identified include:

Failure of follicles to develop

Failure of ovulation

Insufficient thickness of endometrium


The scans are performed by qualified sonographers registered with the Health & Care Professions Council, they are all are experienced in pelvic scanning.
