Objective: Pelvic organ prolapse (POP) affects a large proportion of adult women, but the pathogenesis of POP remains unclear. The increase in global population aging will impose a substantial medical burden. Herein, we aimed to explore the…

Mass cadmium (Cd) poisoning is a serious health problem in many parts of the world. We propose that dietary intervention can be a practical solution to this problem. This study aimed to identify effective dietary products from traditional C…

The vaginal microbiota dysbiosis is closely associated with the development of reproductive diseases. However, the contribution of mycobiome to intrauterine adhesion (IUA) disease remains unknown. Harnessing 16S and ITS2 rDNA sequencing ana…

BACKGROUND: Progress has been achieved by using acupuncture widely for poor endometrial receptivity (PER). However, different acupuncture dosages may lead to controversy over efficacy. OBJECTIVE: To evaluate the evidence-based conclusions …

BACKGROUND AND OBJECTIVE: Cancer is an important disease and can occur anywhere in the body. It is caused by uncontrolled cell growth that spreads to other body parts. This study extensively investigated the transmembrane receptor tissue fa…

Endometrioma (OMA) is the most common subtype of endometriosis, in which the endometriotic lesions are implanted in the ovary. Women with OMA are usually associated with infertility, presenting with reduced ovarian reserve, low oocyte quant…

Abstract Objective: polypoid endometriosis (PEM) is a rare type of endometriosis (EMs), which is easy to be misdiagnosed. The purpose of this paper is to investigate the clinical features and diagnostic methods of PEM. Methods: The clinical…

BACKGROUND: Interleukin-1 receptor type II (IL-1R2), also known as CD121b, is a member of the IL-1 receptor family. IL-1R2 acts as negative regulator of the IL-1 system, modulating IL-1 availability for the signaling receptor. IL-1R2 is abn…

BACKGROUND: The composition of pelvic masses during pregnancy is complex, and over >70% of masses are physiology. Determining the source and nature of tumor tissue is incredibly important in clinical practice, as the proportion of metastati…

We have previously found that TdT-interacting factor 1 (TdIF1) is a potential oncogene expressed in non-small cell lung cancer (NSCLC) and is associated with poor prognosis. However, its exact mechanism is still unclear. The lysine-specific…

Abstract Background: To study which characteristics of a pre-oocyte-retrieval patient can affect the pregnancy outcomes of emergency oocyte freeze-thaw cycles. Methods: Nomogram model performance was assessed by examining the discriminatio…

This study aimed to investigate the clinical factors affecting pregnancy rates following the surgical removal of intrauterine adhesions (IUAs) and subsequent in vitro fertilization and embryo transfer (IVF-ET). We retrospectively evaluated …

Patients who undergo several in-vitro fertilization (IVF) treatment cycles and fail to conceive present a frustrating problem to the clinician. When 1 cycle of IVF treatment fails, should we offer the couples to choose additional cycle of I…
