Oocyte/embryo defects can result in oocyte maturation arrest, fertilization failure, embryonic arrest, and infertility as well as recurrent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) failures. However, the genet…

BACKGROUND: Women with advanced maternal age (AMA) face a significant decline in embryo euploidy rates, leading to reduced fertility and increased risks of adverse pregnancy outcomes. While preimplantation genetic testing for aneuploidy (PG…

BACKGROUND: Preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) has been widely utilized to select euploid embryos in patients carrying balanced chromosomal rearrangements (BCRs) by chromosome copy number anal…

Previous work indicated that the implantation and pregnancy rates of women with endometriosis are lower than those of healthy women during in-vitro fertilisation and embryonic transfer. And there are numerous microRNAs (miRNAs) in human ute…

Abstract Background Previous work indicated that the implantation and pregnancy rates of women with endometriosis are lower than those of healthy women during in-vitro fertilisation and embryonic transfer. And there are numerous miRNAs in h…

BACKGROUND: Studies have shown that supplementation with recombinant human GH (rh-GH) during ovarian stimulation (OS) may improve the ovarian response and clinical outcomes of IVF. However, it remains unclear whether GH is associated with t…

BACKGROUND: To evaluate the differences in pregnancy outcomes between assisted reproductive technology (ART) patients and natural pregnant women in Shanghai, China in the past 6 years objectively. And to assess the feasibility of the resear…

Embryo implantation, a critical step during the mammalian reproductive process, requires normal developing blastocysts and a receptive endometrium. Endometriosis, a common pathologically benign gynecological condition, is associated with de…

BACKGROUND: Previous research has revealed that skewed X chromosome inactivation (SXCI) and androgen receptor (AR) CAG polymorphisms are associated with increased risk of recurrent pregnancy loss (RPL); however, the results are conflicting,…

Objective: The expression of SF-1 in ovarian granulosa cells is critical for follicular growth and development, and the decreased expression of SF-1 in ovarian granulosa cells under endometriosis (EMs) pathology is not clear. This study aim…

Bone marrow-derived cells engraft to the uterine endometrium and contribute to endometriosis. This study sought to further confirm that estrogen can promote the migration of bone marrow mesenchymal stem cells (BMSCs) and to investigate the …

BACKGROUND: The primary aim of the study is to report cases of monozygotic dichorionic-diamniotic (DC-DA) pregnancies after single frozen-thawed blastocyst transfer. METHODS: This is a retrospective case series. All single frozen-thawed bl…

BACKGROUND: Ovarian endometrioma (EM) lesions not only have overwhelmed the amount of infiltrating immune cells but also display immunosuppressive phenotype. The close relationship between neutrophils and the pathogenesis of endometriosis h…

Metabolic profile of follicular fluid (FF) has been investigated to look for biomarkers for oocyte quality. Resolvin E1 (RvE1), a potent pro-resolving mediator, was reported to have protective action in cell function. The study aimed to exa…

BACKGROUND: Previous work demonstrated that there are numerous miRNAs in human follicular fluids, some of which are associated with reproductive diseases. In the current study, we sought to determine whether microRNAs (miRNAs) in the follic…

BACKGROUND: Clinical ovulation induction induces blood estrogen (E2) in excess of physiological levels, which can hinder uterine receptivity. In contrast, progesterone produces the opposite clinical effect, suggesting that it might be capab…
