Intra-uterine Injection of Human Chorionic Gonadotrophin (hCG) Before Embryo Transfer

Overview

Chorionic gonadotrophins (hCG) play an important role in implantation. The aim of the study is to evaluate the effect of intrauterine injection of hCG before embryo transfer in IVF/ICSI on the implantation and pregnancy rates. The rational is that intrauterine hCG injection will attract regulatory T cells and improve implantation.

Background : Human chorionic gonadotrophin ( hCG) was found to secreted immediately after fertilization by the embryo. It plays an important role in implantation and in attracting regulatory T cells to the endometrium. Rational : Intrauterine injection of hCG before embryo transfer in IVF/ICSI may increase endometrial regulatory T cells ( Treg ) and improve the implantation and pregnancy rates. Aim of the work : To study the effect of intrauterine injection of hCG before embryo transfer on the implantation and pregnancy rates after IVF/ICSI. Subjects : Infertile patients undergoing ICSI. Inclusion criteria : * Female age less than 40 years * Male factor infertility * Normal female hormonal profile and uterine cavity Exclusion criteria : * Previous ICSI failure * Azoospermia * Endometriosis Study group: Intrauterine injection of 100 iu of hCG (group 1)or 200 iu of hCG ( group 2) will be done during the dummy embryo transfer which is done 10-15 minutes before the actual embryo transfer. Control group: The embryo transfer will be done without prior intrauterine injection of hCG Main outcome measures : Implantation and pregnancy rates Secondary outcome measures : miscarriage and delivery rates
