Intrauterine Human Chorionic Gonadotrophins (hCG) and Endometrial Treg Cells

November 2, 2013 updated by: Ragaa Mansour, The Egyptian IVF-ET Center

The Effect of Intrauterine Injection of Human Chorionic Gonadotrophins (hCG) on the Endometrial T-regulatory Cells and the Electronmicroscopic Endometrial Characteristics

Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation. It has been demonstrated that regulatory T cells expand during pregnancy. hCG was found to be secreted by the embryo immediately after fertilization and has chemoattractant properties to Treg cells.

Detailed Description

Aim of the work:

To study the effect of intrauterine injection of human chorionic gonadotrophin on the endometrial T regulatory cells (Treg cells)and the electromicroscopic endometrial characteristics.

Background:

It has been demonstrated that regulatory T cells expand during pregnancy and are present at the feto-maternal interface at very early stages in pregnancy.

Rational:

Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation.

Methods:

Intrauterine injection of 100 IU hCG will be done followed by endometrial biopsy to check for Treg cells and pinopodes.
