BACKGROUND: Recurrent implantation failure (RIF) impairs assisted reproductive technology (ART) success, though its mechanisms remain unclear. Studies have implicated altered miRNA expression in the plasma and endometrium of patients with R…

BACKGROUND: Endometriosis is a common gynecological disorder. Non-invasive imaging markers that predict disease severity and bowel involvement are clinically valuable. The purpose of the current study was to evaluate the diagnostic performa…

BACKGROUND: Vitamin D supports oocyte development and ovarian steroidogenesis; deficiency is linked to preeclampsia and poor oocyte quality. The purpose of the current study was to investigate the relationship between vitamin D levels and o…

BACKGROUND: Proteolysis imbalance can result in infertility. The purpose of the current study was to investigate the function of kininogen, neutrophil elastase, trypsin-like proteases, α1-protease inhibitor (α1-PI), and α2-macroglobulin (α2…

BACKGROUND: Accessory cavitated uterine mass (ACUM) is a rare, unclassified Müllerian anomaly characterized by distinct imaging features. It is typically located within the uterus, close to the round ligament, and has a uterus-like structur…

BACKGROUND: The fundamental mechanisms behind the causes and development of endometriosis are still poorly understood. Therefore, identifying biomarkers that can help with early detection and targeted treatment is crucial for effective mana…

BACKGROUND: Neuroendocrine tumors (NETs) or carcinoid tumors are rare neoplasms originating from neuroendocrine cells, most commonly found in the appendix. While NETs are often asymptomatic, they may present with abdominal pain, flushing, a…

BACKGROUND: Endometriosis is a prevalent condition among women, often leading to infertility. Laparoscopic surgery is widely employed as a therapeutic intervention for endometriosis. This study investigated the prognostic factors influencin…

BACKGROUND: Low serum progesterone concentration on the day of frozen embryo transfer (FET) has been associated with adverse pregnancy outcomes. Progesterone supplementation has been shown to improve the outcomes in these cycles. The purpos…

BACKGROUND: IVF/ICSI success depends on the proportion of fertilizable metaphase II (MII) oocytes, yet direct evidence linking mature-oocyte rate to clinical outcomes remains limited. This study aimed to assess the impact of mature oocyte r…

BACKGROUND: Recurrent implantation failure (RIF) refers to the inability to achieve pregnancy after two or three high-quality embryo transfers, representing a significant challenge in in vitro fertilization (IVF). In these women, endometria…

BACKGROUND: The introduction of assisted reproductive technologies (ARTs) has diminished the role of surgery in female factor tubal infertility. The assessment of tubal patency is part of the routine tests taken for the evaluation of infert…

BACKGROUND: Non-obstructive azoospermia (NOA), marked by impaired spermatogenesis, poses challenges in assisted reproduction. Limited data exist comparing chromosomal integrity of testicular versus ejaculated sperm. This study aimed to comp…

BACKGROUND: The occurrence of ovarian hematoma during controlled ovarian stimulation (COS) is very rare. Until now, there is no such case reported in the literature. In this study, an attempt was made to discuss the possible mechanisms for …

BACKGROUND: The purpose of the present study was to investigate the assisted reproductive technology (ART) outcomes after ethanol sclerotherapy (EST) in poor responder patients with endometriomas. METHODS: In this before-after clinical tri…

BACKGROUND: Endometriosis is a gynecologic disorder which causes dysmenorrhea and infertility. Early diagnosis of endometriosis can help prevent the necessity for invasive diagnostic procedures. Medical imaging has been widely utilized to d…

BACKGROUND: The purpose of the current study was to compare the color Doppler findings of uterine arteries and perinatal outcomes in pregnant women with and without previous cesarean section (C/S). METHODS: This cohort study enrolled 308 p…

BACKGROUND: It is hypothesized that fenugreek seeds are a rich source of fiber with anti-diabetic effects, which can help to lower blood glucose in patients with polycystic ovary syndrome (PCOS). In this study, the clinical and metabolic ef…

BACKGROUND: Amenorrhea is defined as the absence of menstruation in women at reproductive age, caused by imbalanced hormonal interactions. The genes located on X chromosome are linked to the physiology of menstruation and reproduction. Earl…

BACKGROUND: Trans-abdominal ultrasound (TAUS) and transvaginal ultrasound (TVUS) are used for embryo transfer. However, few studies were conducted to compare the methods and assess their effect on pregnancy outcomes. METHODS: A retrospecti…

Approximately 99% of people on the planet breathe air that exceeds the World Health Organization's permitted threshold for pollution. South Asia is home to the world's most polluted cities. Population-based studies have suggested that women…

BACKGROUND: Progesterone levels are critical for endometrial receptivity and implantation success in assisted reproductive technology (ART). The purpose of the current study was to determine whether serum progesterone levels on oocyte retri…

BACKGROUND: Endometrial cancer represents the most prevalent malignant genital tract neoplasm in high-income countries and is the second most common cancer worldwide following cervical cancer. Endometriosis is a benign condition wherein end…
