Recent studies have highlighted the crucial role of mechanical properties in the ovarian microenvironment for ovarian function. However, the mechanisms that cause ovarian matrix stiffening during aging remain incompletely understood. Here w…

PurposeTo evaluate the relationships between the sperm DNA fragmentation index (DFI) and semen parameters and its application in fresh embryos via in vitro fertilization and transfer.MethodsA retrospective propensity score matching (PSM) st…

Study questionCan third-generation sequencing (TGS)-based polar body (PB) analysis serve as a viable alternative to conventional trophectoderm (TE) biopsy for preimplantation genetic testing for aneuploidy (PGT-A)?Summary answerThis study d…

BackgroundGlycolysis, a classic characteristic of cancer cells, can drive cancer progression by generating lactate, which play as a key immunosuppressive mediator. Currently, ubiquitin-specific proteases 5 (USP5) has been demonstrated to fa…

BackgroundThe role of sperm DNA fragmentation index (DFI) in fertility remains controversial. Herein, we analyzed its association with semen parameters, embryonic development, and pregnancy outcomes after in vitro fertilization (IVF) treatm…

N-acetylcysteine (NAC) has established use as an antidote for acetaminophen overdose and treatment for pulmonary conditions and nephropathy. It plays a role in regulating oxidative stress and interacting with various cytokines including IL-…

BACKGROUND: Previous studies on the impact of mitochondrial DNA (mtDNA) copy number on female infertility were limited and inconsistent. METHODS: The causal relationship between mtDNA copy number and female infertility was evaluated using …

BackgroundPrimary dysmenorrhea (PD) is a painful disease that severely affects the daily lives of young women. External therapy using traditional Chinese medicine (TCM) is widely used in the clinical treatment of this disease and has achiev…

BackgroundNeuraxial analgesia is widely used to relieve labor pain; its effects on long-term neurodevelopment of offspring remain unclear. This study was designed to investigate the influence of maternal neuraxial labor analgesia on offspri…

STUDY QUESTION: Does the uterine vasculature play a localized role in promoting stromal cell decidualization in the human endometrium? SUMMARY ANSWER: Our study demonstrated that hemodynamic forces induced secretion of specific endothelial …

BackgroundSevere labour pain is an important risk factor of postpartum depression, and early depression is associated with an increased risk of long-term depression; whereas the use of epidural analgesia during labour decreases the risk of …

BACKGROUND: Although it has been more than a century since endometriosis was initially described in the literature, understanding the etiology and natural history of the disease has been challenging. However, the broad utility of murine and…

The endometrium is the inner lining of the uterus. Following specific cyclic hormonal stimulation, endometrial stromal fibroblasts (stroma) and vascular endothelial cells exhibit morphological and biochemical changes to support embryo impla…

Development of adhesions commonly occurs in association with surgery for endometriosis. Even in the absence of surgery, women with endometriosis appear to be at an enhanced risk of developing adhesions. In the current study, we utilized a c…

Humans and other animals are exposed to a wide array of man-made toxicants, many of which act as endocrine disruptors that exhibit differential effects across the lifespan. In humans, while the impact of adult exposure is known for some com…

In a murine model, we have linked early life toxicant exposure to reduced uterine sensitivity to progesterone, a phenotype we had previously associated with inflammation in endometriosis patients. Subsequent studies revealed that developmen…

We have previously described diminished uterine progesterone response and increased uterine sensitivity to inflammation in adult female mice with a history of developmental exposure to TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin). Since partu…

We have recently reported that adult male C57BL/6 mice exposed in utero to the environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) confer an increased risk of preterm birth (PTB) to unexposed females. Risk of PTB was coinciden…

Development of endometriosis likely requires multiple, interactive mechanisms involving both the endocrine and immune systems. Environmental toxicants, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), are of particular interest as potent…
