Item Septate Uterus. Resect or not? That is Not the Only Question(2022) Cok, Tayfun; 0000-0003-1244-7419; 36037812Item What if all the Follicles were already Ruptured at the Time of Oocyte Pick-up in an IVF/ICSI Cycle?(2022) Cok, Tayfun; 0000-0003-1244-7419; 35760360Item Outcomes of Cesarean Scar Pregnancy Treatment: Do We Have Options?(2021) Simsek, Seda Yuksel; Simsek, Erhan; Yaginc, Didem Alkas; Baran, Safak Yilmaz; Cok, Tayfun; Kilicdas, Esra Bulgan; 34082520Objective: To investigate the success and complications of medical and surgical modalities used in the treatment of cesarean scar pregnancies. Materials and Methods: Medical and surgical approaches that have been used to treat cesarean scar pregnancies were evaluated retrospectively, Local, systemic, and combined methotrexate treatments were grouped as the medical approach, and dilatation and evacuation, hysteroscopic resection, laparoscopic and laparotomic approaches were grouped as the surgical approach. Fifty-three patients were diagnosed as having cesarean scar pregnancy during the study period, 48 of whom were included in the final analysis. Eighteen patients were treated with medical interventions and 30 patients were treated surgically. Results: The success rate of surgical modalities was 96.6% and the medical treatment success was 33% (p<0.001). The complication rate was higher with medical approaches compared with surgical methods (66% vs 3.3%, respectively; p<0.001). Conclusion: Surgical intervention seems safer and more successful than medical treatment.Item Rescue Vaginal Cerclage to Stop Funneling Following Laparoscopic Cerclage(2021) Cok, Tayfun; 0000-0003-1244-7419; 34784638Item The effect of preserving prepared sperm samples at room temperature or at 37 C-circle before intrauterine insemination (IUI) on clinical pregnancy rate(2015) Cok, Tayfun; Aytac, Pinar Caglar; Simsek, Erhan; Haydardedeoglu, Bulent; Kalayci, Hakan; Ozdemir, Halis; Kilicdag, Esra Bulgan; 28913033Objective: The comparison of the effect of preserving prepared sperm samples at room temperature or at 37(circle)C before intrauterine insemination (IUI) on clinical pregnancy rate. Materials and Methods: Retrospective clinical research. University hospital, infertility clinic. Patients with one or two follicles, between the ages of 20 and 40, whose infertility period was less than 6 years and the injected total motile sperm count was more than 10 million. Preserving sperm samples prepared for IUI at 37(circle)C or at room temperature before IUI. The clinical pregnancy rate of IUI cycles between 1st of January 2004 and 1st of December 2011 in which prepared sperm samples were preserved at 37(circle)C and the clinical pregnancy rate of IUI cycles between 1st of December 2011 and 31st of May 2014 in which prepared sperm samples preserved at room temperature. Results: Clinical pregnancy rates were similar in IUI cycles in which prepared sperm samples were preserved at 37(circle)C and at room temperature (9.3% vs. 8.9%). Clinical pregnancy rates in IUI cycles with 2 follicles were higher than IUI cycles with 1 follicle (10.8% vs. 7.6%) (p=0.002). Further statistical analysis after splitting data according to the number of the follicles revealed that there was no statistical difference between clinical pregnancy rates after IUI cycles in which prepared sperm samples were preserved at 37(circle)C or at room temperature in both one follicle (7.6% vs. 7.6%), and two follicle cycles (11.5% vs. 10.1%). Conclusions: Preserving prepared sperm samples at room temperature had no negative effect on clinical pregnancy rates when compared with reserving prepared sperm samples at 37(circle)C during IUI cycles.Item Addition of gonadotropin releasing hormone agonist for luteal phase support in in-vitro fertilization: an analysis of 2739 cycles(2015) Simsek, Erhan; Kilicdag, Esra Bulgan; Aytac, Pinar Caglar; Coban, Gonca; Simsek, Seda Yüksel; Cok, Tayfun; Haydardedeoglu, Bulent; 26097392Objective: Luteal phase is defective in in vitro fertilization (IVF) cycles, and many regimens were tried for the very best luteal phase support (LPS). Gonadotropin releasing hormone (GnRH) agonist use, which was administered as an adjunct to the luteal phase support in IVF cycles, was suggested to improve pregnancy outcome measures in certain randomized studies. We analyzed the effects of addition of GnRH agonist to standard progesterone luteal support on pregnancy outcome measures, particularly the live birth rates. Material and Methods: This is a retrospective cohort study, including 2739 IVF cycles. Long GnRH agonist and antagonist stimulation IVF cycles with cleavage-stage embryo transfer were included. Cycles were divided into two groups: Group A included cycles with single-dose GnRH agonist plus progesterone LPS and Group B included progesterone only LPS. Live birth rates were the primary outcome measures of the analysis. Miscarriage rates and multiple pregnancy rates were the secondary outcome measures. Results: Live birth rates were not statistically different in GnRH agonist plus progesterone (Group A) and progesterone only (Group B) groups in both the long agonist and antagonist stimulation arms (40.8%/41.2% and 32.8%/34.4%, p<0.05 respectively). Moreover, pregnancy rates, implantation rates, and miscarriage rates were found to be similar between groups. Multiple pregnancy rates in antagonist cycles were significantly higher in Group A than those in Group B (12.0% and 6.9%, respectively). Conclusion: A beneficial effect of a single dose of GnRH agonist administration as a luteal phase supporting agent is yet to be determined because of the wide heterogeneity of data present in literature. Well-designed randomized clinical studies are required to clarify any effect of luteal GnRH agonist addition on pregnancy outcome measures with different doses, timing, and administration routes of GnRH agonists.Item Reproductive outcomes of office hysteroscopic metroplasty in women with unexplained infertility with dysmorphic uterus(2018) Haydedeoglu, Bulent; Durdag, Gulsen Dogan; Simsek, Seda; Aytac, Pinar Caglar; Cok, Tayfun; Kilicdag, Esra Bulgan; 30202621Objective: The correlation between dysmorphic uterus and infertility still remains enigmatic. We evaluated the reproductive outcomes of metroplasty via office hysteroscopy in unexplained infertile women with dysmorphic uteri. Materials and Methods: In this retrospective cohort study, metroplasty via office hysteroscopy using a bipolar system was performed to 272 women with unexplained infertility with dysmorphic uteri from January 2013 to January 2016. Of all the patients, 162 had primary infertility, and 110 had secondary infertility. Results: In the primary infertility group, the clinical pregnancy rate was 45.68% (74/162) and the live birth rate was 38.9% (63/162), and in the secondary infertility group, the clinical pregnancy rate was 55.45% (61/110) and the live birth rate was 49% (54/110) after metroplasty. In the secondary infertility group, the miscarriage rate and especially the ectopic pregnancy rate declined dramatically [from 84.5% (93/110) to 9.8% (6/61) and from 15.5% (17/110) to 1.6% (1/61), respectively] (p<0.01). Conclusion: Reproductive outcome can be impaired by Mullerian anomalies, hence, infertile women with dysmorphic uteri should undergo hysteroscopy to improve reproductive outcomes. Our study demonstrated that office hysteroscopic metroplasty of a dysmorphic uterus might improve fertility, particularly in patients with unexplained infertility with dysmorphic uteri, which was an ignored factor previously. Office hysteroscopy is an alternative option in terms of non-invasive procedure.
