Neonicotinoid insecticides (NEOs) are emerging environmental contaminants, but their presence and reproductive relevance in the human follicular microenvironment remain poorly understood. We quantified 16 NEOs and metabolites in follicular …

Adenomyosis is a common gynecological disorder with incompletely understood pathogenesis. Through single-cell RNA sequencing of adenomyosis tissues, we identified epithelial-endothelial transition (EET) as a key pathological mechanism and d…

OBJECTIVE: To explore the effects of chromosomal aneuploidy screening and secondary vitrification-warming on the pregnancy and neonatal outcomes of non-biopsied, previously vitrified embryos. METHODS: This retrospective cohort study include…

BACKGROUND: To compare the clinical outcomes between frozen-thawed cleavage embryo transfer and frozen-thawed day 6 blastocyst transfer in patients younger than 35 using the freeze-all strategy without day 5 blastocyst formation. METHODS: …

BACKGROUND: Second-trimester abortion is a critical issue in infertile women with polycystic ovary syndrome (PCOS) treated with assisted reproductive technology (ART), cervical incompetence (CI) may play a role. Although previous studies ha…

BACKGROUND: Although in vitro fertilization (IVF) in infertile patients with endometrial hyperplasia is common after drug treatment, the pregnancy outcomes are often unsatisfactory. Till date, no studies have reported the outcome of patient…

BACKGROUND: Previous studies have shown observational associations between the gut microbiota and endometriosis; however, the causal nature of such associations remains unclear. This study aimed to analyze the genetic causal relationship be…

OBJECTIVE: To assess whether progesterone (P) levels on the trigger day during preimplantation genetic testing (PGT) cycles are associated with embryo quality and pregnancy outcomes in the subsequent first frozen-thawed blastocyst transfer …

BACKGROUND: This retrospective study aimed to investigate the most suitable endometrial thickness (EMT) on the day of embryo transfer that could reduce ectopic pregnancy rate (EPR) and improve clinical pregnancy rate (CPR) in fresh embryo t…

OBJECTIVE: To investigate the effect of BMI in male and/or female partners on embryo development and clinical pregnancy outcome during ART. METHODS: Data of 11,130 cycles between January 2018 and December 2020 were retrospectively analyzed…

BACKGROUND: A number of publications have examined the relation between blood group and female infertility including ovarian reserve, recurrent miscarriage, and live birth. However, there is a lack of literature investigating joint mother/f…

Oocyte retrieval is a routine procedure during the application of assisted reproduction technology. However, technical difficulties experienced during oocyte retrieval and the subsequent unsatisfactory number of oocytes obtained are rarely …

BACKGROUND: To investigate whether the endometrial thickness change ratio from the progesterone administration day to the blastocyst transfer day is associated with pregnancy outcomes in a single frozen-thawed euploid blastocyst transfer cy…

BACKGROUND: The blastocyst morphology provided valuable roles for predicting pregnancy and live birth, but was still not fully understood for evaluating miscarriage. The aim of this study was to explore the association between blastocyst mo…

BACKGROUND: In recent years, some studies have shown that there is a positive association between the number of oocytes retrieved and the cumulative live birth rate (CLBR) after fresh and frozen cycles of one oocyte retrieval. However, almo…

OBJECTIVE: To investigate the effect of seasons on the incidence of high risk of ovarian hyperstimulation syndrome (OHSS) after in oocyte retrieval in patients with polycystic ovarian syndrome (PCOS) and to establish a nomogram to predict t…

Chronic pancreatitis (CP), characterized by pancreatic fibrosis, is a recurrent, progressive and irreversible disease. Activation of the pancreatic stellate cells (PSCs) is considered a core event in pancreatic fibrosis. In this study, we i…

Objective: To study the risk factors for recurrent ectopic pregnancy (REP) in patients undergoing in vitro fertilization (IVF). Methods: This was a 1:4 matched case-control study that enrolled 227 REP patients and 908 matched intrauterine p…

OBJECTIVE: Endometrial injury (EI) is a simple procedure that may improve endometrial receptivity. The purpose of our study was to investigate whether EI improves reproductive outcomes of frozen-thawed embryo transfer (FET) cycles in patien…

BACKGROUND: When ovarian response to FSH stimulation for IVF/ICSI is unsatisfactory, the FSH dose is often adjusted in the treatment cycles, thereby assuming that hormone status and follicular development were insufficient for optimal stimu…

BACKGROUND: Patients with endometriosis (EMs) are routinely advised to take GnRH-a for 3–6 months to improve the internal reproductive environment, but this may not be necessary. MATERIAL/METHODS: This retrospective study examined the effec…

BACKGROUND Patients with endometriosis (EMs) are routinely advised to take GnRH-a for 3-6 months to improve the internal reproductive environment, but this may not be necessary. MATERIAL AND METHODS This retrospective study examined the eff…

BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) is a common and severe complication for patients undergoing IVF/ICSI-ET. Melatonin widely participates in the regulation of female reproductive endocrine activity. However, whether melato…

BACKGROUND: Endometriosis is the major cause of progressive pelvic pain and subfertility. Up to 50% of reproductive-age women suffer from pelvic pain. Endometriosis is a classic indication for IVF. Compared with women whose inability to pro…

Objective: To evaluate the impact of gonadotropin-releasing hormone agonist (GnRH-a) used before surgery on natural pregnancy rates in patients with ovarian endometriomas. Methods: In this retrospective study, 57 patients with ovarian endom…
