endometrial thickness
Ultrasound measurement of the uterine lining used to assess receptivity for implantation.
Full Definition
A transvaginal ultrasound measurement of the endometrial lining thickness, typically assessed in the sagittal plane. Optimal endometrial thickness for embryo transfer is generally considered to be 7-14mm with a trilaminar pattern. Thin endometrium may indicate poor receptivity and reduced implantation potential, while excessively thick endometrium may suggest pathology requiring investigation before embryo transfer.
Usage
Usage note: Often abbreviated as 'endo thickness' or 'ET' in clinical shorthand.
