Background: Fecondation invitro is an outstanding scientific progression in the 20th century. Beside the technical factor and choosing a schedule to reach the fertility rate of high pregnancy, the thickness of uterine endothelium can\u2019t be let pass unnoticed because it is a favorable factor for the embryons which can made easily the foyer in the uterine. Objective: To define the relation between the thickness of uterine endothelium with a concentration of estradiol plasma in the day when injecting hCG with the result of pregnancy. Subject and Method: A retrospective study with research in to 294 cases of IVF. Result: 58.9% is secondary infertile with the average age between 32.6 +/-5.4 who have been infertile in the timescale of 6.4+/-5.0 years. Injecting hCG to take ovocyte when the average estradiol concentradiol is 2378 +/- 1335.9 pg/ml and the estradiol concentration of ovule is 251.4pg/ml. Conclusion: The higher the estradiol concentration is, the thicker the uterine endothelium is. 7.3% cases had uterine endothelium thicker than 10mm if the estradiol concentration is higher than 3000pg/ml. The rate of people who are clinically pregnant with the uterine endothelium > 10mm is 2.24 times higher than the rate of people who are clinically pregnant with the uterine endothelium < 10mm.
