Objective. To evaluate the serum and tissue levels and local expression pattern of tenascin, a high molecular weight extracellular matrix protein, in eutopic and ectopic endometrium from patients with and without endometriosis and to compare the proliferative and secretory phase differences. Materials and Methods. Thirty women with endometriosis and fifteen women without endometriosis undergoing surgery for benign indications were included in the study. Serum and tissue levels and proliferative and secretory phase expression patterns of tenascin in the ectopic and eutopic endometrium were analyzed with immunohistochemistry and immunoassays. The results were compared with Mann-Whitney U test. P values <0.05 were considered as statistically significant. Results. Tenascin expression was detected in both of eutopic and ectopic endometrium of women with and without endometriosis. In immunohistochemical staining, intense staining of tenascin was observed in glandular cells of eutopic and ectopic endometrial tissue samples of both groups during secretory phase (P < 0.01). Eutopic and ectopic tissue levels of tenascin were higher than serum tenascin levels only secretory phase (P = 0.02). There was no significant difference between groups for tissue and serum levels of tenascin during cycle phases. Conclusion. Tenascin expression showed cyclic change on eutopic and ectopic endometrium.

ÖzetAmaç: Reprodüktif çağdaki kadınlarda üriner inkontinans (UI) prevalansını, UI'nın alt tipleri olarak stres (SUI), urge (UUI) ve miks (MUI) inkontinans oranlarını ve buna etki eden faktörleri araştırmak.

AG is an enigmatic disease frequently causing gynecologic complaints and endomyometrial junction deterioration during endometrial sampling may be a trigger point for developing AG.

Background/aim: Basal level of follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and antral follicle count are used as predictors of ovarian reserve before starting ovulation induction. We aimed to investigate the predictor potential of early follicular phase FSH/LH ratio on controlled ovarian hyperstimulation-intracytoplasmic sperm injection (COH-ICSI) cycle outcomes. Materials and methods: This retrospective cohort study was conducted with 648 COH-ICSI cycles performed between 2012 and 2014. Cycles were classified according to their basal FSH/LH ratio, group 1(G1) = FSH/LH ratio < 2, N = 473 and group 2(G2) = FSH/LH ratio ≥ 2, N = 175. Demographic characteristics and stimulation parameters were evaluated. Retrieved total oocyte count (TOC), mature oocyte count (MOC), transferred embryo number, and pregnancy results were obtained and transferred to computer by SPSS 21.0 programme. Results: TOC and MOC of G1 were significantly higher than those of G2. The total gonadotrophin doses of G2 were significantly higher than G1. There was no significant difference between groups for transferred embryo number. Pregnancy and live birth rates were similar in both groups. Conclusion: In our population, increased FSH/LH ratio did not affect the rates of pregnancy and live birth negatively.

In a group of IVF/ICSI cycles, despite the appropriate ovarian stimulation, the number of oocytes collected is below the expected value. This condition is defined as poor ovarian response (POR) to stimulation. POR brings the risk of cycle cancellation with an estimated rate of 20%. Infertility experts are trying to improve cycle outcomes of POR cases with multiple modifications. This review article will present the latest modifications on the management of POR. The studies performed for improving cycle outcome in POR cases were evaluated and their notable results were presented. The first intervention among infertility specialists is to make a standard definition for POR. The BOLOGNA criteria and the subsequent POSEIDON group definitions are the latest updates in POR management. GnRH antagonists, estradiol priming, double stimulation, letrozole administration, DHEA, and herbal therapy supplementations are the recent modifications done to improve oocyte retrieval and subsequent embryo transfer for POR cases. This review article presents the encouraging methods applied for POR cases to improve cycle outcome.

From both histopathological and biochemical analyses, the results of the study demonstrated that metformin has beneficial effects when it comes to attenuating ovarian ischemia-reperfusion injury.
