Endometrial Lining Scan / Transvaginal Ultrasound Scan

What is an endometrial lining scan?

An endometrial lining scan is an ultrasound to check on the womb lining. The endometrial cells that make up this lining will grow every month and then be shed when you have your period. The endometrial lining should reach its thickest point mid-way through your menstrual cycle, when you are ovulating. We will check the womb lining and measure its thickness during the scan to find out if it is ready for an embryo to implant itself.

Why this scan?

  • Measures the thickness of your womb lining
  • Check the health of your endometrial lining
  • Find out when you’re ready for embryo transfer during IVF

What you will receive

  • Endometrial thickness measurements
  • Full ultrasound report to share with your doctor or fertility clinic
  • Scan pictures for your medical records

When Should You Have an Endometrial Lining Scan?

The endometrial lining scan is usually performed when you are undergoing fertility treatments such as IVF. Your fertility clinic may refer you for an endometrial thickness scan in order to check that your womb lining is ready for the embryo transfer. The scan can also be performed as part of a fertility assessment as it can help to identify certain types of fertility problems.

During the scan, we will assess the condition of your womb lining and look for any issues such as uterine fibroids that could be affecting your health or fertility. We will also measure the thickness of the endometrium. The endometrial tissue should grow thicker during the first half of your menstrual cycle. It will reach its thickest point at the same time as ovulation so that it is ready for the embryo to implant and grow if you get pregnant. If you don’t conceive, then it will be shed during your period. The endometrial lining measurement will tell us if your uterus is ready for pregnancy.

What to Expect

  • The scan should be performed at the point in your menstrual cycle when the endometrial lining is at its thickest. The timing will depend on the length of your cycle, but we usually recommend coming in for your first scan on the 9th day of your cycle. If the womb lining isn’t thick enough, you may need to come back for another scan in 1-2 days.
  • We will need to perform a trans-vaginal ultrasound probe in order to measure the endometrial thickness. A slim ultrasound probe will be inserted into your vagina. You will need to remove the lower half of your clothing and you should empty your bladder when you arrive at the clinic.

What is a transvaginal ultrasound scan?

Gynaecological ultrasound and some early pregnancy ultrasound scans are routinely performed using a transvaginal probe technique. This technique is used to view the pelvic anatomy optimally, as the ultrasound probe can transmit safe ultrasound waves more directly to the pelvic area. 
There is no clinical risk associated with performing a transvaginal ultrasound scan. Transvaginal ultrasound scans can safely be performed during menstruation and episodes of vaginal bleeding. 

It is important that you understand the procedure that is associated with this examination.

The ultrasound transducer will be placed in the vagina (the probe is prepared using high grade medical disinfectant)
The transducer will be introduced with a latex / non latex type covering and sterile ultrasound gel.
It will be necessary to move the transducer from side to side, up and down and may be swivelled to obtain ultrasound images of your pelvic anatomy.
If you prefer, you may insert the transducer yourself, otherwise the person conducting the examination will do this.
A third person may be present during the examination acting as a chaperone, if required by the sonographer or yourself.
You may request the examination to be stopped at any time during the procedure.   


If you are a virgin (virgo intacta), guidance determines that transvaginal ultrasound scans are clinically contraindicated. If you have discussed this with your referrer and still wish to proceed with a transvaginal ultrasound scan, we can perform this type of examination for you.
