ObjectiveThis study aimed to compare the pregnancy outcomes of natural cycles (NC) and artificial cycles (AC) in patients undergoing endometrial preparation for frozen-thawed embryo transfer (FET).Materials and methodsThis retrospective coh…

ObjectiveManagement of ovarian endometrioma before IVF treatment is still challenging. We aimed to assess the effect of the pre-cycle surgical removal of endometriomas on IVF outcomes in a large number of cycles in patients undergoing IVF/I…

Background/aim: To investigate the optimal protocol for frozen-thawed embryo transfer (FET) cycles in patients who previously had a cycle cancellation due to uterine peristalsis (UP). Materials and methods: Thirty-four patients with previou…

Our objective was to assess the role of laparoscopic removal of ovarian endometriomas and ablation of peritoneal endometriosis on the outcome of intracytoplasmic sperm injection (ICSI) - Embryo Transfer cycles by comparing with the results …

The aim of this prospective study is to define markers that can be used in the diagnosis and follow-up of patients with endometriosis by determining serum CA 125, transforming growth factor β1 (TGF-β1), interleukin 6 (IL-6), and IL-12 level…

Preoperative blood samples and intraoperative tissue specimens were obtained from 101 patients with endometriosis and 78 patients without endometriosis referred for benign gynecologic operations to investigate the clinical value of serum an…
