The value of endometrial thickness as a predictor of IVF success
A retrospective study conducted by a group of experts from various assisted reproduction clinics, including Dr. Nikolaos Polyzos, clinical and scientific director of the Reproductive Medicine Unit of Dexeus Mujer, monitored a total of 3,350 in vitro fertilisation cycles over a four year period (from 2010-2014). The goal was to assess the value of some of the parameters that are monitored in these cases, including endometrial thickness (EMT), in predicting treatment success.
The authors found that in principle, there is no direct correlation between endometrial thickness and the live birth rate. However, in cases where EMT was below 7.0 mm (21%) or ranged between 7.0 and 9.0 mm (32%), the rate of live births was lower. EMT values below 7 mm were also associated with low birth weight.
These findings confirm that EMT is a useful tool to estimate the rate of live births and to predict birth weight, especially when assessed jointly with other aspects such as patient response to ovarian stimulation based on antral follicle count.
