The Aim of Next Treatment








hCG Injection

Uterine Lumen HCG Injection for Repeated Implantation Failure

For those patients whom suffer from the repeated implantation failure, in which regardless of multiple embryo transfers of high quality embryos pregnancy is not achieved, it has been presented overseas that by injecting a small amount of hCG (Human Chorionic Gonadotropin) into the uterus a few minutes before embryo transfer the pregnancy rate is improved (Mansour R et al., Fertil Steril. 2011 Dec;96(6):1370-1374.e1.).

We are administering hCG injections to the uterine lumen in response to patients who meet the following 2 prerequisites:

・Patients who have a history of repeated embryo transfer failure

・Patients who have given consent on this form after understanding the meaning and necessity of this treatment
