Many factors influence the success of IVF treatment. Alongside known factors such as embryo quality, maternal age, and ovarian reserve, the condition of the uterine lining, or endometrium, where the embryo will implant, is also of vital importance. For pregnancy to occur, the presence of a suitable environment where a healthy embryo can implant in the uterine wall plays a critical role. At this point, endometrial thickness has become one of the most closely monitored parameters in IVF treatment. As Ankara IVF Center, founded by Prof. Dr. Kubilay Vicdan and our team, we aim to provide the most effective treatment approaches tailored to each patient's individual needs. In this article, we will delve into why the thickness of the uterine lining is so crucial for transfer and address common questions on this topic.
Ideal Thickness Range
Before embryo transfer, the uterine lining, or endometrium, is expected to reach a certain thickness and structure. This condition is one of the most important factors directly affecting the embryo's chance of implantation. Generally, an ideal endometrial thickness of 7 mm to 14 mm is preferred. Most clinical and scientific studies indicate that endometria with a thickness of 8 mm or more yield more favorable results in terms of pregnancy rates. However, this is a threshold value, and successful pregnancies can sometimes be achieved with endometria around 7 mm.
Not only the thickness but also the structure of the endometrium is of great importance. A "triple-layered" or "trilaminar
