In this study, our objective was to evaluate the impact of testicular histopathology on the outcome of intracytoplasmic sperm injection (ICSI) cycles of patients with nonobstructive azoospermia and correlate with clinical and hormonal parameters. For this purpose, 271 patients with nonobstructive azospermia (NOA) who underwent testicular sperm extraction (TESE) for ICSI cycles were retrospectively evaluated for sperm retrieval, fertilisation, embryo cleavage, clinical pregnancy and live birth rates among different testicular histology groups. We also correlated hormonal and clinical factors with histological findings. Sperm retrieval and fertilisation rates (FR) were found to be significantly different among all testicular histological groups of NOA except for embryo cleavage, clinical pregnancy and live birth rates. Furthermore, serum follicle stimulating hormone (FSH) level was the most significant variable to predict sperm recovery on TESE. Separate analyses within each testicular histological group revealed that higher FSH was also associated with lower pregnancy rates in only maturation arrest group. In conclusion, testicular histology significantly influences sperm retrieval and FRs but not pregnancy and live birth rates in nonobstructive azoospermia. However, FSH is the best predictor of a successful TESE.

Aim: The aim is to identify the chronic endometritis (CE) incidence in recurrent implantation failure (RIF) patients undergoing in vitro fertilization (IVF) treatment and compare the IVF outcomes of RIF patients with CE following antibiotic therapy with RIF patients without CE. Another purpose is to compare the IVF outcomes of described RIF patients with patients undergoing the first cycle of IVF. Methods: In this retrospective cohort study, CE was diagnosed with CD-138 immunohistochemical staining. Among RIF patients, two groups were formed as group 1, including patients diagnosed with CE and treated by antibiotics (n = 129), and group 2, including patients without CE (n = 103). Patients with the first IVF cycle having similar infertility etiologies with RIF patients were reviewed as group 3 (n = 932). Results: CE was diagnosed in 55.6% of RIF patients. The number of oocytes retrieved was not different between groups. Implantation rates (IR) were similar after antibiotic treatment in RIF patients with or without CE. However, Group 3 had a higher IR (41.1%) than group 1 and 2 (23.1% and 30.1%, respectively) (p < 0.001). Clinical pregnancy (CPR) and live birth rates (LBR) were comparable between RIF groups. However, CPR and LBR were significantly higher in group 3 (48.6% and 40.5%) than group 1 (36.4% and 27.9%), and group 2 (37.9% and 30.1%) (p = 0.007 and p = 0.005, respectively). Conclusion: Unidentified endometrial factors except CE may also affect the implantation process, although CE is a frequent finding in patients with RIF. Reproductive outcomes may not be improved only with antibiotics in RIF patients with CE.

Our aim was to evaluate the presentation and diagnostic evaluation of patients with isolated tubal torsion and to evaluate the surgical approach to these patients. We also aimed to define the ultrasonographic diagnostic criteria. Five patients with isolated tubal torsion who were admitted to our gynecology department between January 2014 and January 2017 were evaluated and included in this study. All cases were diagnosed through ultrasonographic imaging alone. The preoperative findings of the patients were similar to those described in the literature. No further imaging modality was used for diagnosis and all patients were managed with laparoscopy. The clinical findings and ultrasonographic findings were consistent with literature. It may be difficult to preoperatively diagnose isolated tubal torsion, which is a rare clinical entity. Evaluation of these patients by an experienced sonographer and knowledge of the ultrasonographic findings of isolated tubal torsion may have vital preventive measures.

Labour augmentation and actual birth weight higher than 4000 g were identified as risk factors for clavicle fracture in cases of brachial plexus injury.

Treatment of ectopic pregnancy with either expectant management or systemic MTX is equally effective as compared to surgery. Spontaneous intrauterine pregnancy rates were comparable in expectant management, systemic methotrexate and surgery.

Aim: To evaluate whether the duration of sexual abstinence has impact on oxidative stress in semen samples. Methods: Oxidative reaction was tested for different levels of reactive oxygen species (ROS) by nitro blue tetrazolium assay in 90 patients with the diagnosis of unexplained or male factor infertility that were grouped into 3 groups as 0-2 (group 1), 3-4 (group 2) and >4 days (group 3) of duration of sexual abstinence. Subsequently, the remaining semen was prepared by gradient method for ovarian stimulation and intrauterine insemination (IUI) cycles to compare pregnancy rates in terms of different levels of ROS and different abstinence periods. Results: Increased staining pigment intensity was related to higher level of ROS in >4 days' group as compared to groups 0-2 and 3-4 days (70% vs 43.3% and 50%, P = 0.013 and P = 0.014, respectively). Pregnancy rates significantly decrease with prolonged abstinence period (26.7%, 16.7% and 6.7% in groups 1, 2 and 3, respectively, P = 0.039). Progressive motile sperm count after gradient method of sperm preparation for IUI was highest in 3-4 days of abstinence period than shorter and longer abstinence groups. Conclusion: Longer duration of sexual abstinence causes higher oxidative stress and decreases pregnancy rates in IUI cycles.

As this study was not a randomized controlled trial, a decisive conclusion may not be possible. However, until well-designed controlled studies are conducted, expectant management may be appropriate up to the full-term period and induction of labor may be appropriate management when the full-term period is reached.
