The influence of endometrial thickness on embryo transfer: Literature review

Abstract

Infertility affects millions of couples around the world, and is considered a significant challenge to global health. Even after 12 months of attempts without contraception, many fail to conceive, which highlights the importance of assisted reproductive techniques as a viable solution. Over the years, several approaches have been developed to increase the chances of successful fertilization, with embryo transfer being one of the most used. However, the success of this procedure can be influenced by multiple factors, including endometrial thickness. This study aims to explore the impact of endometrial thickness on embryo transfer and its relationship with the clinical evolution of oocytes. The research consists of a narrative review of the last 10 years of literature, resulting in the in-depth analysis of 5 articles selected from 147 initial findings. The results indicate that endometrial thickness not only affects embryo transfer and oocyte development, but may also be associated with gestational complications, such as hypertensive disorders in pregnancy.
