Objective: To explore the relationship between chromosome translocation and their phenotypic effect by analyzing the patients with loss pregnancy and avoiding fetuses with chromosomal abnormalities.
Methods: A total of 3067 cases with infertility or loss pregnancy were recruited to receive chromosome examination during January 2005 to December 2011 at Center of Prenatal Diagnosis, Peking University People's Hospital. Retrospective study was used to analyze the chromosome karyotypes and infertility or loss pregnancy.
Results: In 72 cases of patients with chromosome translocation, there were 17 pregnancies with homology translocation in fetus. And the numbers of patients with loss pregnancy and sex apparatus malformations were 40 and 15 respectively.
Conclusion: Chromosome translocation plays an important role in patients with loss pregnancy or infertility. And chromosome examination should be performed to exclude the possibility of chromosome abnormities in patients with obstinate infertility.

Department of Medical Surgical Disciplines, Faculty of Medicine, Titu Maiorescu University of Bucharest, 031593 Bucharest, Romania.
In approximately half of the recurrent spontaneous abortion (RSA) cases, the underlying cause is unknown. However, most unexplained miscarriages are thought to be linked to immune dysfunction. This review summarizes the current evidence regarding the immunological evaluations of patients with RSA, with potential implications for clinical research.

Management of second-trimester placenta accreta spectrum (PAS) is currently center-dependent with minimal evidence-based practices. This study aims to analyze outcomes of hysterectomy as second-trimester active management (AM) versus cesarean hysterectomy as expectant management (EM) in cases of PAS with intraoperative and postoperative outcomes. This study is a retrospective case-control study of patients with a pathology-confirmed diagnosis of PAS managed at a single center over 16 years (2005-2020).

Chronic endometritis (CE) is a persistent inflammatory condition of the endometrium characterized by abnormal infiltration of plasma cells into the endometrial stroma. Frequently associated with repeated implantation failure, recurrent pregnancy loss, and infertility, CE significantly impacts women's health, contributing to conditions such as abnormal uterine bleeding and endometriosis. Treatment typically involves antibiotic therapy; however, the efficacy of these treatments is increasingly compromised by the rise of antimicrobial resistance (AMR).

Abnormally fertilized embryos are often discarded during in vitro fertilization due to the fact that known chromosomal ploidy abnormalities lead to implantation failure or pregnancy loss. The objective of this study was to determine if pronuclear numeration (PN) observed at fertilization check is representative of the true ploidy status of the subsequent developing blastocyst in order to maximize the number of viable embryos available for infertility patients and increase their chances of conception. Upon successful fertilization, pronuclear numeration was noted, and zygotes were cultured to the blastocyst stage.

Purpose: This study aimed to monitor the expression of B-cell translocation gene 2 (BTG2) in granulosa cells of patients undergoing IVF/ICSI with respect blastocyst quality outcomes.
Methods: We recruited 181 women undergoing IVF/ICSI cycles for infertility. Granulosa cells were extracted from follicular fluid.
