Intrauterine infusion of human chorionic gonadotropin before embryo transfer in IVF/ET cycle: The critical review.

Am J Reprod Immunol 2019 Feb 23;81(2):e13077. Epub 2019 Jan 23.

Department of Microbiology and Immunology, Chicago Medical School, Rosalind Franklin University of Medicine and Science, North Chicago, Illinois.

Intrauterine infusion of human chorionic gonadotropin (IUI-hCG) has been proposed to improve the outcome of in vitro fertilization-embryo transfer (IVF-ET), since it plays a critical role in synchronizing endometrial and fetal development. As the early mediator from embryo, hCG promotes the decidualization, angiogenesis, maternal immune tolerance, and trophoblast invasion, favoring successful implantation of embryo. Although multiple clinical trials have been conducted to verify the efficacy of IUI-hCG on IVF-ET outcome in recent years, the findings remained controversial. Read More

Extracellular matrix remodeling effects of serum amyloid A1 in the human amnion: Implications for fetal membrane rupture.

Am J Reprod Immunol 2019 Jan 10;81(1):e13073. Epub 2018 Dec 10.

Shanghai First Maternity and Infant Hospital, Tongji University School of Medicine, Shanghai, China.

Problem: Rupture of fetal membranes is a crucial event at parturition, which is preceded by extensive extracellular matrix (ECM) remodeling. Our recent studies have demonstrated that the human fetal membranes are capable of de novo synthesis of serum amyloid A1 (SAA1), an acute phase protein, and the abundance of SAA1 in the amnion was increased at parturition. However, the exact role of SAA1 in human parturition remains to be established. Read More

Endometrial microbes and microbiome: Recent insights on the inflammatory and immune "players" of the human endometrium.

Am J Reprod Immunol 2018 Dec 30;80(6):e13065. Epub 2018 Oct 30.

Dipartimento di Scienze della Salute della Donna e del Bambino, Area Salute Donna, Fondazione Policlinico Universitario A.Gemelli IRCCS, Rome, Italia.

In recent years, extended scientific works shed light on the important role played by the endometrium in early pregnancy. This review examines our current knowledge about the delicate balance between microbial and cellular immune agents at endometrial level: All of them might affect endometrial receptivity. In contrast to the classical thinking of human endometrium as a sterile tissue, several recent studies have drawn attention to a resident population of microorganisms, which reaches only a 30% of concordance with those of the cervical-vaginal flora.
