endometrial thickness
The measurement of the endometrial lining, typically assessed via transvaginal ultrasound to evaluate uterine receptivity for embryo implantation.
Full Definition
Endometrial thickness refers to the measurement of the endometrial lining of the uterus, typically assessed through transvaginal ultrasound during fertility treatment cycles. This measurement is crucial for determining optimal timing for embryo transfer, as adequate endometrial thickness (generally 7-14mm) indicates better receptivity for implantation. Insufficient thickness may indicate the need for additional estrogen supplementation or cycle cancellation.
Usage
Usage note: Always specify the measurement in millimeters and the cycle day when documenting.
In Context
- "The patient's endometrial thickness measured 8.2mm on day 14 of the cycle, indicating adequate preparation for transfer." — IVF cycle monitoring report
- "Thin endometrial thickness below 7mm may compromise implantation rates." — Clinical assessment note
