Abstract:

Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg intrauterine rhCG (n=84) or placebo (n=98) before ET. The implantation and pregnancy rates were compared between groups. Results: Patients who received intrauterine rhCG before ET had significantly higher implantation (36.9% vs. 22.4%; p=0.035), clinical pregnancy rates (34.5% vs. 20.4%; p=0.044) and ongoing pregnancy rate (32.1% vs. 18.4%; p=0.032) when compared to those who received placebo. The abortion (2.4% vs. 2.0%; p=0.929) and ectopic pregnancy rates (1.2% vs. 1.0%; p=0.976) were comparable between groups. Conclusion: Intrauterine injection of 250 μg of rhCG before ET significantly improves the implantation and pregnancy rates in IVF/ICSI.

the effect of intrauterine human chorionic gonadotropin injection before embryo transfer on the implantation and pregnancy rate in infertile patients: a randomized clinical trial

background: implantation is one of the essential steps for the success of assisted reproductive techniques (art). their success depends on three main factors: embryo quality, endometrial receptivity (er), and synchrony between embryo and endometrium. there are various factors that regulate the complex process of implantation. in this regard, one may refer to human chorionic gonadotropin (hcg) a...

Effect of intrauterine injection of human chorionic gonadotropin before embryo transfer on clinical pregnancy rates from in vitro fertilisation cycles: a prospective study

BACKGROUND The implantation process after embryo transfer depends on the embryo quality and endometrial receptivity. It is estimated that fifty to seventy-five per cent of pregnancies are lost due to a failure of implantation. There is evidence that there is an early secretion of human chorionic gonadotrophin before embryo implantation, and this secretion has been linked to an important functio...
