BACKGROUND: PCOS-related infertility is closely linked to metabolic dysfunction. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) improve insulin resistance and promote weight loss in women with PCOS, but their direct effect on reproduc…

RESEARCH QUESTION: Do embryo parameters and live birth rates differ between patients with endometrioma undergoing a freeze-all strategy using either GnRH antagonists or progestin-primed ovarian stimulation (PPOS)? DESIGN: This retrospectiv…

PURPOSE: The aim of this study was to assess the effectiveness of the GnRHa trigger in the PPOS and GnRH antagonist protocols when using a GnRH agonist (GnRHa) trigger. METHODS: This retrospective cohort study conducted at Bahçeci Fulya IV…

PURPOSE: To provide technical guidance on applying catheter-directed and needle-directed ethanol sclerotherapy for endometriomas and present the results of these sclerotherapy methods. MATERIALS AND METHODS: From January 2015 to March 2021…

Abstract Study question Do embryological parameters and live birth rates differ in patients with endometriosis undergoing freeze-all approach when GnRH-antagonist protocol or progestin primed pituitary suppression(PPOS) was preferred? Summa…

Abstract Study question Is there any difference in ongoing pregnancy rate in women with thin endometrium (<8 mm) when scrutinized based on estradiol levels on triggering day? Summary answer Either with a low, moderate, or high estradiol …

OBJECTIVE: To assess the effect of dienogest treatment on endometrioma (OMA) size, serum anti-Mullerian hormone (AMH) levels and associated pain over a 12-month follow-up period. MATERIAL AND METHODS: A longitudinal cohort study of 104 pat…

Abstract Study question Is there a protective effect of oral sphingosine-1-phosphate analogue (S1P) on ovarian reserve? Summary answer The use of oral long acting S1P analogue may reduce spontaneous primordial follicle loss and preserve ova…

Abstract Study question Does utilization of dienogest make any impact on the size of cyst and Anti-Müllerian Hormone (AMH) concentration in patients with endometrioma throughout 12-months? Summary answer Although dienogest makes a gradual r…

Although hydrothorax may accompany abdominal ascites in women with severe ovarian hyperstimulation syndrome (OHSS), there are few cases reported with isolated pleural effusion. Herein, we report two patients with isolated hydrothorax withou…

PURPOSE: There is no established non-invasive method to diagnose patients with endometriosis. As a nondestructive type of radiation, infrared light might be used for discrimination by causing vibration of the covalent bonds of the molecules…

Study question Are live birth rates (LBR) different after ART cycles between women with primary or recurrent endometrioma? Summary answer Women with recurrent endometrioma have similar LBR as compared to patients with primary endometrioma. …

STUDY QUESTİON: Are live birth rates (LBR) different after ART cycles between women with primary or recurrent endometrioma? SUMMARY ANSWER: Women with recurrent endometrioma have similar LBR as compared to patients with primary endometrio…

Study question: To compare the pregnancy rate in patients submitted to FET (Frozen Embryos Transfer) of cleavage stage embryos (Group 1), or at the blastocyst stage (Group 2). Summary answer: Our data showed that the transfer of frozen blas…

Endometriosis has a wide clinical spectrum and induces a chronic inflammatory process. The incidence of endometriosis in women with dysmenorrhoea is up to 40-60%, whereas in women with subfertility is up to 20-30%. Recurrence of endometrios…

BACKGROUND: Our aim was to determine the effect of single endometriomas ≤3 cm in diameter per se on ovarian reserve in intracytoplasmic sperm injection (ICSI) cycles. METHODS: We enrolled 19 consecutive infertile patients (29 cycles) who h…

OBJECTIVE: To assess the impact of prior unilateral or bilateral endometrioma cystectomy on controlled ovarian hyperstimulation (COH) and intracytoplasmic sperm injection (ICSI) outcome. DESIGN: Retrospective case-control study. SETTING: …
