Intrauterine Instillation of Human Chorionic Gonadotropin with Intrauterine Insemination Catheter Around the Golden Time of Embryo Transfer Does Not Improve In Vitro Fertilization /Intracytoplasmic Sperm Injection Outcomes in Infertile Women: A Randomized Controlled Trial

Background: We set out to explore the effect of intrauterine human chorionic gonadotropin (hCG) instillation by intrauterine insemination (IUI) catheter before embryo transfer (ET) on assisted reproductive technologies (ART) outcomes of infertile women.   Methods: One hundred women with infertility who were scheduled for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles were included in the study. They were randomly devoted to two groups: experimental (n= ۵۰) and control (n= ۵۰). In the experimental group, ۵۰۰ IU hCG passed into the internal cervical orifice via IUI catheter within ۱۵ minutes before the transfer of fresh or vitrified cleavage-stage embryos. The control group underwent the same ET procedure without prior injection of hCG.   Results: None of the outcomes showed a statistically significant difference between the two groups. In the intervention and control groups, respectively, biochemical pregnancies rates were ۲۶% and ۱۸%, implantation rates were ۱۳.۵% and ۸.۶%, clinical pregnancies rates were ۲۲% and ۱۴%, ongoing pregnancies rates were ۱۸% and ۱۴%, and live birth rates were ۱۴% and ۱۲%.   Conclusions:Intrauterine injection of hCG via IUI catheter is not recommended in a clinical routine setting at this stage. Future efforts are warranted to further refine the applicability of this modality.
