About

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.

Full description

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

Enrollment: 472 patients

Sex: Female

Ages: 20 to 39 years old
