OBJECTIVE: Endometriosis (EMs) is a chronic gynaecological condition characterised by the ectopic growth of endometrial tissue; however, its molecular mechanisms remain insufficiently understood. Ferroptosis, an iron-dependent form of regul…

BACKGROUND: Endometriosis is heterogeneous, and evidence for individualised postoperative management is limited. We assessed whether postoperative hormonal therapy exposure is associated with one-year changes in pain domains after first-tim…

BACKGROUND: Adenomyosis causes severe dysmenorrhoea and menorrhagia. While the Levonorgestrel-Releasing Intrauterine System (LNG-IUS) is a highly effective conservative treatment, its success is frequently compromised by high expulsion rate…

BACKGROUND: The gamma-glutamyl transferase (GGT) to high-density lipoprotein (HDL) ratio (GGT/HDL) has recently emerged as a potential biomarker for metabolic and liver diseases. This study aimed to investigate the association between GGT/H…

BACKGROUND: This study investigates how clinical factors and hormonal levels affect oocyte retrieval in modified natural cycles, aiming to improve understanding and enhance treatment protocols. METHODS: A retrospective analysis of data fro…

BACKGROUND: Endometriosis is a chronic inflammatory disease with a prevalence of approximately 10% in women of childbearing age. Metabolic pathways have been demonstrated by previous studies to be potential avenues for the development of ne…

BACKGROUND: The aetiology and pathogenesis of adenomyosis remain unclear. This study utilised untargeted metabolomics to explore the aberrant amino acid metabolism in adenomyosis. Among the studied metabolites, hydroxyproline is known to pr…

BACKGROUND: Adenomyosis is a common gynaecological condition where ectopic endometrial glands and stroma grow within the myometrium. This condition has a high clinical burden impacting those afflicted with debilitating symptoms including he…

BACKGROUND: Previous observational evidence has indicated the potential involvement of the gut microbiota (GM) in the development of endometriosis. However, the causal relationship of the association remains to be investigated. METHOD: Gen…

BACKGROUND: This study examined the improvement of dysmenorrhoea and menorrhagia after uterine artery embolisation (UAE) in women with symptomatic adenomyosis and identified factors that could predict the improvement of dysmenorrhoea and me…

BACKGROUND: Haemostasis during ovarian cystectomy is reported to damage the ovarian reserve, but the comparative impacts of three haemostasis methods (bipolar energy, suture and haemostatic sealant) on ovarian reserve in patients with ovari…

BACKGROUND: A biopsychosocial approach to the understanding of pelvic pain is increasingly acknowledged. However, there is a lack of standardised instruments - or their use - to assess risk factors and their impact on pelvic pain in both cl…

BACKGROUND: Abnormal stromal-epithelial cell communication is a pathogenic mechanism in endometriosis, and metformin can modulate it. Insulin-like growth factor binding protein-1 (IGFBP1) plays a role in endometriosis, but the exact mechani…

BACKGROUND: Interleukin (IL)-2 is a key cytokine capable of modulating the immune response by activating natural killer (NK) cells. This study was recruited to explore the therapeutic potential of IL-2-activated NK-92 cells in endometriosis…

INTRODUCTION: The diagnosis of endometriomas in patients with endometriosis is of primary importance because it influences the management and prognosis of infertility and pain. Imaging techniques are evolving constantly. This study aimed to…

This was a retrospective study that evaluated a total of 280 patients who underwent surgery for complete removal of endometriosis to develop and validate the predictive model for stage IV endometriosis. The differences between stage I-III a…

Adenomyosis is a condition characterised by the invasion of endometrial tissues into the uterine myometrium, the molecular pathogenesis of which remains incompletely elucidated. Lesion profiling with next-generation sequencing (NGS) can lea…

This meta-analysis aimed to determine the accuracy of transvaginal ultrasound (TVS) and pelvic magnetic resonance imaging (MRI) in diagnosing urinary tract endometriosis (UTE). A comprehensive search of the Pubmed and Embase was conducted b…

Younger women with endometriosis report lower quality of life and seek more care. Patient-centeredness is a central part of quality of care. The aim of this study was to investigate if women younger than 35 years experience endometriosis ca…

A retrospective observational study of new patients who visited the gynaecology outpatient clinic at Tygerberg Hospital, South Africa, between February and June 2019 was conducted to determine the association between body mass index (BMI) a…

Maternity statistics of England in 2020 showed rise in Caesarean Section (CS) rate to 31%. Some studies correlated adverse gynaecological symptoms e.g. menstrual irregularities and pelvic pain to 'niche' formation at CS scar site. Niche for…

The aim of this study was to investigate the reproductive profiles, metabolic parameters and cardiometabolic risk assessed by surrogate indexes in women with adenomyosis. Ninety-six premenopausal women who were diagnosed with adenomyosis by…

This study aimed to compare the effectiveness of NAC plus low dose contraceptive with low dose contraceptives alone. This was a randomised trial on a sample of women who underwent conservative laparoscopic surgery for ovarian endometrioma. …

This study aimed to investigate the effect of early inflammatory reaction on ovarian reserve of patients with ovarian endometriomas after laparoscopic cystectomy. Our retrospective case series included 112 patients with ovarian endometrioma…
