Infertility Clinical Trial
Official title:
Intra-uterine Injection of Human Chorionic Gonadotrophin Before Embryo Transfer in ICSI
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

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
