To Which Patients Should Intrauterine HCG Injection Be Applied In In Vitro Fertilization?

Aim: To investigate the impact of the intrauterine injection of hCG before embryo transfer in in vitro fertilization (IVF) according to number oftransfer.Material And Methods: One hundred and sixty-eight (168) patients wereincluded to the study group; 274 patients were included to the controlgroup. The patients were divided into 2 study and 2 control groups.Group 1:Study group patients in the first and the second IVF cycles.(N=126)Group 2:Control group patients in the first and the second IVF cycles.(N=189)Group 3:Study group patients in the third or more IVF cycles. (N=42)Group 4:Control group patients in the third or more IVF cycles. (N=85)Fresh IVF-embryo transfer (ET) was performed to all patients. IntrauterinehCG injection was performed before ET in the study groups.Results: The pregnancy, clinical pregnancy and implantation rates weresignificantly increased in the intrauterine hCG injected patients with thirdor more IVF cycles (p= 0.03, p= 0.02, p= 0.02) respectively.Conclusion: The intrauterine hCG injection improved the pregnancy ratesin the patient with recurrent IVF failures.
