Endometrial thickness
Measurement of the womb lining, interpreted according to cycle stage, menopausal status, symptoms and treatment history.
Focused womb-lining assessment • London & St Albans
Same-day private ultrasoundA focused pelvic ultrasound assessing the thickness, pattern and appearance of the endometrium — the lining of the womb — for abnormal bleeding, fertility and IVF monitoring, HRT or tamoxifen surveillance, and other gynaecological concerns.

Direct answer
An endometrial lining scan is a focused gynaecological ultrasound that measures the lining inside the uterus and assesses its appearance in relation to your menstrual cycle, age, symptoms, fertility treatment or hormonal medication.
The endometrium is measured in the standard plane and assessed for thickness, pattern, contour and focal irregularity. The uterus, ovaries and surrounding pelvic structures are also reviewed so the measurement is interpreted in context.
What the scan assesses
Measurement of the womb lining, interpreted according to cycle stage, menopausal status, symptoms and treatment history.
Assessment of whether the lining is uniform and appropriate for the clinical context.
Assessment for focal thickening, suspected polyps or other intracavitary abnormalities.
Review for fibroids, adenomyosis-type features, uterine shape abnormalities and cavity distortion.
Assessment of ovarian morphology, cysts, follicles and surrounding adnexal regions where visible.
Review for free fluid, hydrosalpinx where visible and other pelvic findings relevant to fertility or bleeding.
When it may help
Clinical interpretation
The lining naturally changes during the menstrual cycle, becoming thin during menstruation and thicker through the proliferative and secretory phases.
Thickness and pattern are interpreted alongside follicular development, medication and the fertility clinic’s treatment plan.
Endometrial thickness has different significance after menopause, particularly in the presence of bleeding or hormone therapy.
Before you arrive
Transvaginal ultrasound generally provides the clearest endometrial views and is usually performed with an empty bladder.
If an initial transabdominal view is planned, you may be asked to arrive with a comfortably full bladder first.
Bring the first day of your last period, usual cycle length, bleeding pattern and fertility-treatment schedule.
Previous pelvic scans, hysteroscopy, fertility letters and HRT/tamoxifen details are useful.
Your appointment
Your symptoms, cycle day, menopausal status, fertility treatment and medication are reviewed.
The uterus and endometrium are assessed, usually with transvaginal imaging for best detail.
Endometrial thickness is measured and focal abnormalities are assessed; Doppler may be added when useful.
Main findings are usually explained after the scan, followed by a formal written report.

Common reasons include abnormal or postmenopausal bleeding, irregular periods, fertility or IVF monitoring, suspected polyps or thickening, and HRT or tamoxifen monitoring when clinically indicated.
Transvaginal ultrasound usually gives the clearest endometrial view, but it is only performed with informed consent. You may decline or stop the internal examination at any time.
It assesses endometrial thickness, pattern, contour and focal abnormalities, while also reviewing the uterus, ovaries, adnexa and other visible pelvic structures.
Ultrasound may show focal thickening or features suggesting a polyp. Some cases need saline sonography, hysteroscopy or specialist review for confirmation.
There is no single normal value for everyone. Thickness varies across the menstrual cycle and is interpreted differently before and after menopause and with HRT or tamoxifen.
No. Ultrasound can identify thickening or irregularity that needs investigation, but diagnosis requires appropriate clinical assessment and, when indicated, endometrial sampling or hysteroscopy.
For a transvaginal scan an empty bladder is generally preferred. If transabdominal views are also required, you may be asked to arrive with a comfortably full bladder first.
Main findings are usually explained after the scan, with a formal digital report and relevant images typically provided within 24 hours.
