BACKGROUND: Thyroid autoimmunity (TAI) is prevalent among women of reproductive age and has been associated with impaired fertility; however, its effects on ovarian reserve and infertility treatment outcomes remain controversial. METHODS: …

AIM: Despite growing public attention toward infertility treatments and elective oocyte cryopreservation, awareness of fertility among young adults remains limited. Accurate knowledge of age-related fertility declines and ovarian reserve is…

AIM: To investigate whether the etiology of diminished ovarian reserve (DOR) independently influences outcomes of assisted reproductive technology (ART). METHODS: This multicenter, retrospective cohort study was a secondary analysis of a n…

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common cause of irregular menstrual cycles and infertility. Current treatments primarily involve ovulation induction and sex steroid hormone therapy. Tokishakuyakusan (TSS) is a traditional …

BACKGROUND: Endometriosis is an estrogen-dependent chronic inflammatory disease, however the mechanisms underlying inflammation remain unclear. Non-hormonal drugs that can prevent endometriosis progression and resolve endometriotic infertil…

Abstract Extracellular vesicles (EVs) are secreted from mammalian cells and bacteria and are involved in disease pathogenesis. Recently, bacterial factors have been linked to the pathogenesis of endometriosis. Therefore, identifying host-ba…

Abstract Study question Does endometriosis affect oocyte quality and subsequently embryonic development in ART? Summary answer Endometriosis did not affect embryonic development until the mid-30s, but in the late 30s, it further exacerbated…

Abstract Study question Could azithromycin (AZM) prevent endometriotic lesion progression by targeting cellular senescence? Summary answer AZM can prevent the progression of endometriotic lesions by inhibiting the secretion of interleukin-6…

BRCA1 is one of the causative genes for hereditary breast and ovarian cancer syndrome with a high risk of early-onset breast cancer. Whereas olaparib (OLA), an inhibitor of poly-ADP-ribose polymerase, has been applied as adjuvant therapy to…

The mainstay of treatment for endometriosis is hormonal therapy, which suppresses ovulation; therefore, patients cannot conceive during treatment. There is a dilemma with ovarian-sparing surgery, known as laparoscopic cystectomy, as it can …

PurposeNon-previa placenta accreta spectrum (PAS) is associated with assisted reproductive technology (ART), particularly frozen embryo transfer during hormone replacement therapy (HRC-FET). We especially aimed to evaluate the prevalence an…

INTRODUCTION: Endometriosis can cause of infertility, and evaluation methods for predicting clinical pregnancy outcomes are desired. Extracellular vesicles (EVs) exist in blood and it contains small non-coding RNAs (ncRNAs) that may reflect…

BACKGROUND: Assisted reproductive technology accounts for an increasing proportion of infertility treatments, and assessments to predict clinical pregnancy outcomes are desired. Extracellular vesicles exist in follicular fluid, and small no…

Retrograde menstruation is a widely accepted cause of endometriosis. However, not all women who experience retrograde menstruation develop endometriosis, and the mechanisms underlying these observations are not yet understood. Here, we demo…

PURPOSE: This study aimed to investigate whether serum leucine-rich α2-glycoprotein (LRG) is a useful diagnostic biomarker for endometriosis, including the evaluation of treatment efficacy and exploration of LRG production in endometriotic …

Ovarian endometrioma (OE) is a common gynecological disease that is often treated with surgery and hormonal treatment. However, ovarian cystectomy can impair the ovarian reserve (OR). Previously, we showed that perioperative administration …

BACKGROUND: Endometriosis is a complex syndrome characterized by an estrogen-dependent chronic inflammatory process that affects 10% of women of reproductive age. Ovarian endometriosis (OE) is the most common lesion in endometriosis and may…

BACKGROUND: Ovarian endometrioma is a common gynecological disease that is often treated with surgery or hormonal treatment. Ovarian cystectomy, a surgical procedure for ovarian endometrioma, can result in impaired ovarian reserve. METHODS…

Blastocyst implantation involves multiple interactions with numerous molecules expressed in endometrial epithelial cells (EECs) during the implantation window; however, there is limited information regarding the molecular mechanism underlyi…

Appendiceal intussusception secondary to endometriosis is extremely rare. We report a case of left ovarian endometriosis with endometriosis-induced appendiceal intussusception in a 42-year-old woman presenting with rectal bleeding and left-…

OBJECTIVE: To establish and characterize cell lines derived from human endometrial epithelial cells (ECs) and mesenchymal cells (MCs) from patients with and without endometriosis. DESIGN: In vitro experimental study. SETTING: University a…

Endometriosis has several distinguishing features in the ectopic endometrium, including chronic inflammation and fibrosis. According to the retrograde menstruation theory, endometriotic cells are derived from eutopic endometrial cells, and …

Repeated tissue injury and repair and fibrosis play a pivotal role in endometriosis. Fibrotic tissue consists of extracellular matrix proteins, regulated by transcriptional factors promoting cell proliferation and survival. Periostin is one…
