Defective endometrial decidualization is one major cause of female infertility, yet the underlying mechanisms remain elusive. Here, we identified that protein arginine methyltransferase 5 (PRMT5), which was upregulated during decidualizatio…

INTRODUCTION: Although advanced paternal age (APA) is increasingly scrutinized in reproductive medicine, its independent impact on embryo development and clinical outcomes remains contentious, particularly when controlling for maternal age …

Objective: This study aimed to elucidate the regulatory mechanisms of the long intergenic non-protein coding RNA 02381 (LINC02381)/microRNA-let-7g-5p (let-7g-5p)/thrombospondin 1 (THBS1) signaling axis in osteosarcoma (OS). Methods: The exp…

BACKGROUND: This study aimed to evaluate the clinical outcomes of umbilical cord mesenchymal stem cell (UC-MSC) transplantation on ovarian function in women with premature ovarian insufficiency (POI), and its potential to improve in vitro f…

STUDY QUESTION: Does abnormal serotonin homeostasis contribute to impaired endometrial decidualization in patients with recurrent implantation failure (RIF)? SUMMARY ANSWER: Abnormal serotonin homeostasis in patients with RIF, which is acc…

BACKGROUND: Previous studies suggested higher serum progesterone (P) levels were strongly associated with a lower clinical pregnancy rate (CPR) for in vitro fertilization-embryo transfer (IVF-ET). However, the effect of increased serum P le…

RESEARCH QUESTION: To investigate the effects of two protocols (hormone replacement therapy (HRT) alone or in combination with tamoxifen) on the endometrium and pregnancy outcome of patients with thin endometrium in frozen-thawed embryo tra…

BACKGROUND: Successful embryo implantation requires the attachment of a blastocyst to the receptive endometrial epithelium, which was disturbed in the women with recurrent implantation failure (RIF). Endometrial β3-integrin was the most imp…

RESEARCH QUESTION: The relationship between serum progesterone (P) and luteinizing hormone (LH) levels on the human chorionic gonadotropin (hCG) trigger day and the clinical pregnancy outcomes in modified natural frozen-thawed embryo transf…

BACKGROUND: Infertility is one of the most important and underappreciated reproductive health problems in developing countries. Currently, in vitro fertilization and embryo transfer is the most effective treatment strategy for infertility. …

Purpose: To evaluate the clinical utility of serum luteinizing hormone (LH) level in predicting frozen embryo transfer (FET) outcomes among the patients with an ovulation induction (OI) cycle. Methods: A total of 250 patients who underwent …

BACKGROUND: This study aimed to explore the relationship between serum oestrogen (E2) levels before endometrial transformation and pregnancy outcomes of hormone replacement therapy-frozen embryo transfer (HRT-FET) cycles, which has been inv…

Decidualization is a complex process involving cellular proliferation and differentiation of the endometrial stroma and is required to establish and support pregnancy. Dysregulated decidualization has been reported to be a critical cause of…

The establishment of endometrial receptivity is a prerequisite for successful pregnancy. Women with adenomyosis possess a lower chance of clinical pregnancy after assisted reproductive technology, which is partially due to impaired endometr…

BACKGROUND: Recurrent implantation failure (RIF) remains a critical and challenging problem in assisted reproductive technology mainly due to impaired decidualization. The endocytic and transcytotic activity in the endometrium are crucial f…

OBJECTIVE: To analyze the clinical outcomes of repeated superovulation induction in patients with adenomyosis or moderate to severe pelvic endometriosis after failure in previous IVF-ET cycles with the ultra-long protocol. METHODS: We retr…

OBJECTIVE: To evaluate if the expression and chemotactic activity of RANTES are different in IL-1beta treated autologous eutopic endometrial stromal cells compared to ectopic and normal endometrium. STUDY DESIGN: Conditioned media from IL-…

Until the early 1980s the standard treatment for the malignant bone tumors of the extremities was amputation at or above the joint proximal to the tumor. After surgery a period of watchful waiting ensured the results, and then more than two…
