[Predictive value of endometrial pattern and thickness in the result of in vitro fertilization and embryo transfer].
In order to assess the relationship between echographic endometrial thickness and pattern and the probability of clinical pregnancy and delivery we analyzed retrospectively 51 cycles of IFV-ET. Patients were classified in three categories of endometrial thickness: < 9 mm, 9.1-11 mm and > 11 mm and in two types of endometrial pattern: type 1 (non triple line) or type 2 (triple line). The average endometrial thickness of patients who got pregnant and those who did not was 11.8 +/- 1.8 mm and 10.6 +/- 1.7 mm respectively (p = NS). There were no clinical pregnancies in patients with endometrial thickness < 9 mm (p < 0.01). The average endometrial thickness in patients with endometrial pattern type 1 and type 2 was 11.1 +/- 1.2 mm and 10.9 +/- 1.9 mm respectively (p = NS). Patients who presented type 2 endometrial pattern (n = 39) produced eleven clinical pregnancies (28.2%) and those with type 1 (n = 2) only one clinical pregnancy (8.3%), which ended in spontaneous abortion (p < 0.01). When both variables, thickness and pattern, were considered together, patients with endometrial pattern type 2 and thickness > 11 mm had a probability of clinical pregnancy and of delivery of 43.8% and 25%, respectively, who is statistically significant (p < 0.03). We conclude that endometrial thickness and pattern, taken together, offer a valuable prognostic value for the outcome of an IVF-ET cycle.
