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.
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.
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.
Intrauterine injection of hCG around the time of implantation may increase endometrial Treg cells and improve implantation.
Intrauterine injection of 100 IU hCG will be done followed by endometrial biopsy to check for Treg cells and pinopodes.

A prospective randomized study included 210 women with Unexplained infertility subjected to combined ovarian stimulation and Intrauterine insemination (IUI). Two equal groups. Study group,...
The purpose of this trial is to study whether addition of different doses of human chorionic gonadotropins during controlled ovarian stimulation for patients undergoing IVF will improve th...
The aim of this study is to assess the role of AMH in prediction of poor ovarian response as well as the relation between ESR2 (+1730G>A) (rs4986938), FSHR p.Thr307Ala (c.919A>G, rs6165) a...
The follicular phase of the menstrual cycle involves the hourly release of gonadotropin-releasing hormone, which binds to receptors on the gonadotropes. This results in the secretion of fo...
The purpose of this study is to compare the clinical outcomes of recombinant human chorionic gonadotrophin (rHCG) and urinary HCG (uHCG) in patients undergoing IVF cycles.
We investigated the association of human chorionic gonadotrophin (hCG) concentrations on a fixed day in very early pregnancy with development of hyperemesis gravidarum.
The aim of this study was to improve clinical decision-making for the identification of persistent ectopic pregnancy after linear salpingostomy. The study identified 854 laparoscopic salpingostomies p...
Evaluation of Prolidase Activity, Oxidative Stress and Antioxidant Enzyme Levels in Testicular and Penile Tissues after Human Chorionic Gonadotropin Treatment in Rats by Predicting Infertility and Erectile Dysfunction.
Prolidase plays a vital role in collagen turnover, matrix remodeling and cell growth. We aimed to evaluate the association between treatment with chorionic gonadotropin and infertility and erectile dy...
Dual trigger of final oocyte maturation with a combination of GnRH agonist and hCG versus a hCG alone trigger in GnRH antagonist cycle for in vitro fertilization: A Systematic Review and Meta-analysis.
Increasing evidence indicates that a dual trigger (a gonadotrophin-releasing hormone agonist [GnRH-a] with a human chorionic gonadotrophin [hCG] trigger) is the best choice for final oocyte maturation...
The magnitude of ovulation rate (OR) after hormonal induction in sheep should be considered when prolific genotypes are used. We investigated for the first time the effect of the Vacaria allele and it...
The beta subunit of luteinizing hormone. It is a 15-kDa glycopolypeptide with structure similar to the beta subunit of the placental chorionic gonadatropin (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN) except for the additional 31 amino acids at the C-terminal of CG-beta. Full biological activity of LH requires the non-covalently bound heterodimers of an alpha and a beta subunit. Mutation of the LHB gene causes HYPOGONADISM and infertility.
The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.
Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.
A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).
Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.
