Problem: Predicting the impact of systemic inflammation on oocyte and embryonic development in unexplained infertile women using the new immunological indexes.

Method Of Study: This retrospective cohort study was conducted using the records of the In Vitro Fertilization Department of Ankara Gülhane Training and Research Hospital. After reviewing the records of patients who had undergone in vitro fertilization (IVF) for unexplained infertility (UI) and excluding all known factors that could cause systemic immune inflammation, the systemic immune response index (SIRI), and pan-immune score were calculated from the pre-treatment hemogram parameters between the embryo arrest (EA) group and the embryo transfer group.

Introduction: Cancer-related venous thromboembolism is one of the leading causes of mortality and morbidity in cancer patients. Lung cancer is the second most common cancer in the world and is closely related to venous thromboembolism. Venous thromboembolism affects survival in patients with cancer and it is important to be able to predict the possibility of thrombosis in patients with cancer.

Background: Gonadotrophin-releasing hormone agonist (GnRHa) downregulates gonadotropin secretion in the pituitary gland. It is used both in ovulation induction protocols and in artificial endometrium preparation. Frozen-thawed embryo transfer to artificially prepared endometrium (FET-APE) is a frequent procedure in vitro fertilization (IVF) which requires GnRHa.

We aimed to compare repeated LPP (luteal phase oestradiol LPP/GnRH antagonists protocol) treatment with different protocol results with poor ovarian response (POR) patients. Two hundred and ninety-three cycles with poor ovarian reserve who underwent LPP, microdose flare up protocol and antagonist protocol were included in the study. Of these, 38 patients were applied LPP in the first cycle and LPP in the second cycle.

Robotic gait training helps the nervous system recover and strengthen weak muscle groups. Many studies in the literature show that applying robotic gait rehabilitation to patients with neurological disorders such as Multiple Sclerosis (MS), Stroke and Spinal Cord Injection (SCI) effectively restores gait ability. In contrast to the studies in the literature that included only healthy individuals, both the control and patient groups were formed and detailed analyses were carried out for both groups.

Objective: The aim of this study was to analyze the results of microsurgical testicular sperm extraction (micro-TESE) and investigate the potential factors that may affect the successful sperm retrieval and timing of micro-TESE.

Methods: A total of 56 patients with nonobstructive azoospermia (NOA) who underwent micro-TESE procedure between January 2017 and December 2019 were retrospectively analyzed. The patient age, marriage duration, infertility duration, smoking, chronic illness, varicocele status, previous scrotal surgeries, and the presence of genetic disease were noted by an urologist for all patients.

The design, production and adaptability to clinical routine of a patient-specific tumor and respiratory monitoring phantom (TRMP) was investigated using 3D printer technology. TRMP and GTV modelling were done using 4D-CT images of the inhalation phase. The model was converted to STL (Stereolithography) format and printed with STH (Strong Herbal) biopolymer with HU (Hounsfield Unit) suitable for imaging purposes.

Purpose: There is evidence that follicular phase progesterone rise [FPPR] adversely affects fresh in vitro fertilization [IVF] cycles. A single daily dose of cetrorelix has been used to prevent early luteinizing Hormone (LH) surge. We speculated that doubling the daily dose might have a positive effect in patients who have early LH surges despite receiving the single daily dose treatment.

Aim: To investigate the use of Augmented Reality (AR) technology as it contributes to spinal surgery education with the free-hand technique, and might reduce the error ratio.

Material And Methods: Ten candidates, with anatomy education but no surgical experience, applied 36 pedicle screws with C2-C3 posterior transpedicular fixation technique to nine vertebrae models produced via a three-dimensional (3D) printer.

Results: Using AR to apply pedicle screws to the experimental vertebrae model increased the safety screw ratio significantly.

The objective of this study was to compare the rates of clinical pregnancy after the transfer of vitrified and thawed human embryos on days 3, 4 and 5 of embryonic development. In this retrospective study, the results of 148 embryo transfer cycles, using embryos frozen and thawed over the 3-year period between January 2016 and December 2018 at the Gülhane Training and Research Hospital Department of Gynecology and Obsterics Reproductive Medical Center of the University of Health Sciences, Ankara, Turkey were examined. Following embryo transfer - including 29 dissolved embryos frozen on day 3, 80 frozen on day 4, and 39 frozen on day 5 - results were examined in terms of clinical pregnancy rates.

Introduction: The use of robotics for benign etiology in gynecology has not proven to be more beneficial when compared to traditional laparoscopy. The major concern regarding robotic hysterectomy stems from its high cost.

Aim: To evaluate the clinical utility and effectiveness of one-arm reduced robotic-assisted laparoscopic hysterectomy as a cost-effective surgical option for total robotic hysterectomy.

A unicornuate uterus with a rudimentary horn is an anomaly caused by defective fusion of the Müllerian duct, estimated to occur in one in 76,000 pregnancies. Life threateningly heavy bleeding is a highly expected clinical consequence of such pregnancies. According to the known literature, only two living twins and few living singleton pregnancies have been reported up to now.

According to the lower uterine segment and trophotropism hypotheses of placental implantation, placentation occurs in uterine segments with a high blood supply. The present study was designed to determine the clinical implications of these hypotheses by assessing the dynamics of the third stage of labor. Two-hundred and ninety-two prospectively followed pregnant women were assessed at the time of delivery.

OBJECTIVE: To examine the effects of a levonorgestrel-releasing intrauterine device (LID) in patients with female sexual dysfunction and who were using this device for contraception. STUDY DESIGN: The results before device application and at the 6-month follow-up were compared using the female sexual function index (FSFI) test on a sample of 36 patients with female sexual dysfunction who had requested the use of the LID for contraception. RESULTS: The FSFI scores before the placement of an LID and at 6-month follow-up were determined to be 19.

Background: Current cervical cancer screening guidelines recommend a 1-year follow-up period for patients with a postmenopausal low-grade squamous intraepithelial lesion (LSIL) who are test negative for high-risk human papillomavirus (HrHPV). The aim of this study was to assess whether such patients had an increased immediate risk of high-grade squamous intraepithelial lesion.

Methods: We assessed 54 HrHPV-negative women with postmenopausal LSIL in the Department of Obstetrics and Gynecology of our hospital between 2012 and 2013.
