Does Microfluidic Sperm Sorting Affect Embryo Euploidy Rates in Couples with High Sperm DNA Fragmentation?

Male infertility contributes as the main factor in 30-50% of infertility cases. Conventional methods for sperm preparation have induced questioning of sperm recovery rates. The microfluidic sperm sorting (MSS) technique selects highly motile sperm with lower levels of SDF (sperm DNA fragmentation) compared to conventional sperm sorting techniques. This study aimed to determine whether utilizing this technique will reveal better embryo quality and euploidy rates in couples with repeated implantation failure (RIF) and high SDF in a new PGT-A (preimplantation genetic testing for aneuploidies) cycle. This retrospective study included couples referred to PGT-A for previous repeated ART (assisted reproductive techniques) cycle failures and with high SDF. In their new cycles, couples who accepted the technique were assigned to the MSS group, and the rest were managed with DGC (density-gradient centrifugation). Two groups were compared in terms of fertilization and euploidy rates, clinical miscarriage and live birth rates, the total number of blastocysts, and top quality blastocysts. There was no difference between the groups regarding fertilization rates, euploidy rates, clinical miscarriage, and live birth rates. The total number of blastocysts and top quality blastocysts were significantly higher in the MSS group. The MSS technique provides a higher number of top-quality blastocysts than DGC; however, neither euploidy nor live birth rates improved. Studies focusing on confounding factors to embryonic genomic status in the presence of high SDF are needed.

Oral antibiotic prophylaxis in elective cesarean deliveries: pilot analysis in tertiary Care Hospital.

INTRODUCTION: Puerperal infection remains a significant cause of maternal morbidity and mortality. Those infections occur more likely after cesarean delivery (CD). Prophylactic antibiotics are administered at the time of CD to prevent complications. In addition to intraoperative prophylaxis; prescription of antibiotics during hospital discharge to prevent surgical site infections (SSI) is quite common. Purpose of this study is to determine the utility of prophylactic oral antibiotic prescription in a cohort of low-risk women undergoing CD. MATERIALS AND METHODS: A prospective observational study was conducted between 2014 and 2018 at Ufuk University School of Medicine, Department of Obstetrics and Gynaecology. Total of 389 low risk elective cesarean deliveries were selected. All cases received intraoperative prophylaxis. In group I (157 subjects), no further antibiotics were given and in group II (232 cases), oral cephuroxime 500 mg was given during hospital discharge. Primary outcome was SSI. Secondary outcomes were endometritis and other infectious conditions. RESULTS: Overall SSI rate was 2.5%. Only 2 SSIs were noted in group 1 (1.2%) compared to eight in group II (3.4%). There was no statistical difference in SSI rate between two groups. Secondary outcomes were also comparable. CONCLUSION: In this study, we failed to reveal any beneficial effect of oral antibiotic prescription during hospital discharge in low risk elective CDs. Therefore, use of oral antibiotics in addition to intraoperative prophylaxis should be questioned in terms of increased costs, emergence of bacterial resistance and long term effects on new born as a consequence of changes in gut microbiome.

DNA fragmentation index and human papilloma virus in males with previous assisted reproductive technology failures.

OBJECTIVE: This study was designed to evaluate the prevalence of Human Papilloma Virus (HPV) in semen and document the cycle outcomes in couples with previous intra-cytoplasmic sperm injection (ICSI) failures. MATERIAL AND METHODS: One hundred and seventeen couples with at least two ICSI attempts were included in the study. HPV infection in semen and DNA fragmentation in samples were analyzed by commercially available kits. The percentage of spermatozoa with fragmented DNA (DNA fragmentation index: DFI) was determined during fluorescence microscopic examination as previously described. The cycle outcomes of couples with or without HPV infected male partners were recorded. RESULTS: According to our results, the prevalence of HPV was 7.7% in asymptomatic males with at least two previous ICSI failures. The increased DFI (>30%) was observed in 82.9% of the cases. In HPV-positive cases significantly lower number of good quality embryos were obtained. The implantation and pregnancy rates were similar in infected and non-infected males (p>0.05). The early miscarriage rate was slightly higher in HPV- positive group (33% vs. 10%, p>0.05). CONCLUSION: In cases with previous ICSI failures, the prevalence of HPV infection in semen is not higher than previously reported infertile populations. The reproductive outcome might be impaired in HPV-positive semen due to lower number of good quality embryos, which needs to be clarified by further large population-based studies.

A retrospective comparative study of prednisolone use in antagonist co-treated assisted reproductive technology cycles for patients with good prognosis.

OBJECTIVE: To investigate the impact of peri-implantation prednisolone use and its duration in antagonist co-treated assisted reproductive technology (ART) cycles of patients with good prognosis. MATERIALS AND METHODS: Infertile patients treated with gonadotropin-releasing hormone antagonist protocol between January 2010 and June 2013 were included. The patients in group A (n=196) received no prednisolone. The patients in groups B (n=397) and C (n=371) received 5 mg oral prednisolone daily, for 4 and 12 days following embryo transfer, respectively. The main outcome parameter was live birth rate. RESULTS: The ages of the groups were 30.1±4.6, 31.5±4.5, and 30.9±4.7 years, respectively (p=0.163). There was no statistically significant difference between the groups regarding cycle characteristics. Implantation rates were 20.7%, 24.6%, and 23.8%, respectively (p=0.163). Miscarriage rates were 1.5%, 3.5%, and 3.2%, respectively (p=0.859). Live birth rates were 28.7%, 29.3%, and 32.8%, respectively (p=0.482). CONCLUSION: Empiric prednisolone administration during the peri-implantation period does not seem to have beneficial effects in ART cycles of patients with good prognosis.

Pro-Gastrin Releasing Peptide: A New Serum Marker for Endometrioid Adenocarcinoma.

BACKGROUND: Gastrin-releasing peptide (GRP) is thought to play a role in the metastatic process of various malignancies. The more stable precursor of GRP, pro-GRP (ProGRP), has been shown to be secreted by neuroendocrine tumors. This study was designed to assess the validity of ProGRP as a diagnostic marker in endometrioid adenocarcinomas (EAs) of the endometrium. METHODS: Thirty-seven patients with a diagnosis of EA, 23 patients with endometrial hyperplasia, and 32 age-matched controls with normal endometrial histology were recruited for this study. Serum ProGRP and cancer antigen 125 (CA125) values were compared between groups. RESULTS: Median serum ProGRP levels were significantly higher in the cancer group compared to corresponding levels in both the hyperplasia and control groups (p = 0.008 and p < 0.001 respectively; endometrial cancer: 27.5 pg/mL; hyperplasia: 16.1 pg/mL; controls: 12.9 pg/mL). Age and endometrial thickness were positively correlated with ProGRP levels (r = 0.322, p = 0.006 and r = 0.269, p = 0.023, respectively). Receiver Operating Characteristic curve analyses for EA revealed a threshold of 20.81 pg/mL, with a sensitivity of 60.7% and specificity of 81.4%, positive predictive value of 68% and negative predictive value of 76.1%. CONCLUSION: Significantly higher ProGRP levels were observed in patients with EA than in controls. Serum ProGRP has good diagnostic sensitivity and specificity for EA.

Neutrophil Gelatinase-Associated Lipocalin Levels During Pneumoperitoneum.

BACKGROUND AND OBJECTIVES: A temporary deterioration in renal function during pneumoperitoneum has been reported, but the extent is not known. A new marker for the early detection of renal injury, neutrophil gelatinase-associated lipocalin (NGAL), has been shown to increase in various conditions that affect renal function. This study was conducted to explore detrimental effects of pneumoperitoneum in laparoscopic surgery on renal function by studying levels of urinary NGAL (uNGAL). METHODS: Thirty-two women scheduled to undergo laparoscopic surgery in a gynecology clinic were recruited. NGAL was measured in urine collected at the beginning (0 h) and at 2 and 24 hours after the initiation of surgery. Hemodynamic parameters were analyzed immediately after intubation and before desufflation. RESULTS: Levels of uNGAL increased from 5.45 ng/mL at 0 hours to 6.35 ng/mL at 2 hours and to 6.05 ng/mL at 24 h; however, there was no significant change in uNGAL levels at the collection time points. Intraoperative oliguria was observed in all cases, and the severity increased with the duration of surgery. uNGAL levels did not correlate with the duration of surgery or pneumoperitoneum. CONCLUSION: In patients with normal renal functions, pneumoperitoneum results in transient oliguria without any early renal damage, as indicated by nonsignificant changes in uNGAL levels.

The Impact of Gradually Increasing Energy Dose on AMH Levels in Ovarian Drilling.

BACKGROUND: To document alterations in Anti-Müllerian hormone (AMH) levels with different energy doses by monopolar cautery in ovarian drilling (OD) in rats. METHODS: Forty Wistar rats were randomly divided into 4 groups that each contained 10 animals. Group A was the Sham group. Groups B, C and D were intervention groups to which OD was applied by monopolar cautery, with 20, 60 and 120 J/ovary, respectively. The total amount of energy was calculated using the following formula: energy (J) = power (W) × duration (s) × number of punctures. RESULTS: The pre- and postoperative AMH levels for Groups A, B and C were not statistically and significantly different according to the Bonferroni correction (p > 0.0125). However, the postoperative AMH levels were significantly lower than the preoperative AMH levels in Group D (1.25 ng/ml (1.07-2.05) vs. 0.40 ng/ml (0.30-0.72); p = 0.012). CONCLUSIONS: AMH is a promising marker that can be used for the individualization of the energy dose to increase OD success, but the relationship between the energy and AMH has not been documented yet. This study demonstrates that postoperative changes in AMH levels could be observed only after a certain amount of energy was applied. Further experimental animal models are needed to conclusively address this issue.

Impact of office hysteroscopy in repeated implantation failure: Experience of a single center.

OBJECTIVE: Repeated implantation failure (RIF) is a clinical entity affecting many couples undergoing assisted reproductive technology (ART). Various intrauterine pathologies contribute to RIF. Nevertheless, vaginal sonography and hysterosalpingography, which are the common diagnostic tools for the initial follow-up, have limited sensitivities. In this context, we aimed to evaluate the impact of office hysteroscopy (oHS) on live birth rates (LBRs) when performed prior to subsequent ART cycles in women with a history of RIF. MATERIAL AND METHODS: The database of an assisted reproduction center was retrospectively reviewed to detect eligible cases. A total of 363 women out of 2875 admissions were consecutively included in the analysis, of which 119 formed the oHS group and 244 formed the non-oHS group prior to a new ART cycle. Women in the oHS arm were examined during their early follicular phase via a vaginoscopic approach 1-6 months before the beginning of a new cycle. The standard in-vitro fertilization-intracytoplasmic sperm injection (IVF/ICSI) cycle was applied to all the women. RESULTS: In the oHS group (n=119), 61 patients had intrauterine abnormalities, with an overall abnormality rate of 51.2%. Implantation, pregnancy, and LBRs of the groups were statistically similar. LBRs of the women with abnormal oHS findings (15/61, 24.5%), with normal oHS findings (14/58, 24.1%), and without oHS (39/244, 16%) were statistically similar (p=0.41). CONCLUSION: Unrecognized intrauterine pathologies can be easily detected and concurrently treated during oHS with high success rate. However, a beneficial impact depends on the extent of the pathology and thus, routine application to enhance reproductive outcomes is still not warranted.

Electrocardiographic P-Wave Duration, QT Interval, T Peak to End Interval and Tp-e/QT Ratio in Pregnancy with Respect to Trimesters.

BACKGROUND: P-wave duration helps to determine the risk of atrial arrhythmia, especially atrial fibrillation. QT interval, T peak to end interval (Tp-e), and Tp-e/QT ratio are electrocardiographic indices related to ventricular repolarization which are used to determine the risk of ventricular arrhythmias. We search for any alterations in electrocardiographic indices of arrhythmia in the pregnancy period with respect to trimesters. METHODS: We enrolled 154 pregnant and 62 nonpregnant, healthy women into this cross-sectional study. Maximum and minimum P-wave durations (Pmax, Pmin), and QT intervals (QTmax, QTmin) were measured from 12 leads. QT measurements were corrected using Fridericia (QTc-Fr) and Bazett's (QTc-Bz) correction. Tp-e interval was obtained from the difference between QT interval, and QT peak interval (QTp) measured from the beginning of the QRS until the peak of the T wave. Tp-e/QT ratio was calculated using these measurements. RESULTS: Pmax were 93.0 ± 9.1, 93.9 ± 8.9, 97.9 ± 5.6, 99.0 ± 6.1 in nonpregnant women, first, second, third trimesters of pregnancy, respectively (P = 0.001); whereas Pmin values were not significantly different. QTc-Fr max were 407.4 ± 14.2, 408.5 ± 16.1, 410.1 ± 13.1, 415.1 ± 10.1 (P = 0.007); Tp-e were 72.7 ± 6.2, 73.2 ± 6.5, 77.2 ± 8.9, 87.2 ± 9.6 (P < 0.001); and Tp-e/QT were 0.17 (0.14-0.20), 0.17 (0.14-0.20), 0.18 (0.15-0.23), 0.20 (0.16-0.25) in nonpregnant women, first, second, and third trimesters of pregnancy respectively (P < 0.001). None of the participants experienced any arrhythmic event. CONCLUSIONS: P-wave duration is prolonged in the second trimester, and resumes a plateau thereafter. Maximum QTc interval, Tp-e interval and Tp-e/QT ratio are increased in the late pregnancy. Although these indices are altered during the course of pregnancy, they all remain in the normal ranges.

Estrogen or anti-estrogen for Bologna poor responders?

The current study aims to compare cycle outcomes of two ovarian stimulation protocols in poor responders according to the Bologna criteria; luteal estrogen priming (LE) or letrozole (LZ) co-treatment in antagonist protocol. Following retrospective chart review of a single center, 162 cycles were found eligible for the comparison of two ovarian stimulation protocols. After interpreting data, significantly higher serum estradiol levels, longer duration of cycle, higher number of fertilized oocytes and good quality embryos were detected in patients who received LE. Despite any statistical significance, higher clinical pregnancy rate (CPR) and ongoing pregnancy rate (OPR) per embryo transfer (ET) were detected with LE protocol compared with LZ (12.3% versus 18.2% and 9.6% versus 12.7%, respectively). Younger patients (<40 years) revealed higher CPR and OPR per started cycle compared with older patients (≥40 years) where only OPR was statistically significant. Multivariable analysis demonstrated that basal antral follicle count, peak serum estradiol levels and number of fertilized oocytes were independent variables significantly associated with clinical pregnancies (p < 0.05). In the current analysis, LE or LZ protocols revealed comparable but quite low pregnancy rates in poor responders according to the Bologna criteria. Younger patients were more likely to achieve pregnancy compared to older patients with both protocols.

Different gonadotropin releasing hormone agonist doses for the final oocyte maturation in high-responder patients undergoing in vitro fertilization/intra-cytoplasmic sperm injection.

CONTEXT: Efficacy of gonadotropin releasing hormone agonists (GnRH-a) for ovulation in high-responders. AIMS: The aim of the current study is to compare the impact of different GnRH-a doses for the final oocyte maturation on cycle outcomes and ovarian hyperstimulation syndrome (OHSS) rates in high-responder patients undergoing ovarian stimulation. SETTINGS AND DESIGNS: Electronic medical records of a private in vitro fertilization center, a retrospective analysis. SUBJECTS AND METHODS: A total of 77 high-responder cases were detected receiving GnRH-a. Group I consisted of 38 patients who received 1 mg of agonist and Group II consisted of 39 patients who received 2 mg of agonist. STATISTICAL ANALYSIS: In order to compare groups, Student's t-test, Mann-Whitney U-test, Pearson's Chi-square test or Fisher's exact test were used where appropriate. A P < 0.05 was considered as statistically significant. RESULTS: Number of retrieved oocytes (17.5 vs. 15.0, P = 0.510), implantation rates (46% vs. 55.1%, P = 0.419) and clinical pregnancy rates (42.1% vs. 38.5%, P = 0.744) were similar among groups. There were no mild or severe OHSS cases detected in Group I. Only 1 mild OHSS case was detected in Group II. CONCLUSION: A volume of 1 or 2 mg leuprolide acetate yields similar outcomes when used for the final oocyte maturation in high-responder patients.

Early pregnancy loss following laparoscopic management of ovarian abscess secondary to oocyte retrieval.

Severe pelvic infections following ultrasound-guided transvaginal oocyte retrieval (TVOR) are rare but challenging. Ovarian abscess formation is one of the consequences and management of such cases as highly debated in pregnant patients. In this case report, an early fetal loss following laparoscopic management of ovarian abscess is described and possible etiologies are discussed.

Improved cycle outcomes after laparoscopic ovarian diathermy in hyper-responder patients with previous ART failure.

Excessive response to ovarian stimulation is common among hyper-responder patients undergoing assisted reproductive technology (ART). Cycle cancellations and severe ovarian hyperstimulation syndrome (OHSS) are all detrimental consequences observed within this cohort and several approaches have been proposed to enhance outcomes. The current study is designed to evaluate whether laparoscopic ovarian diathermy (LOD) improves ART outcomes and pregnancy rates by reducing Anti-mullerian hormone (AMH) levels in a group of patients who had a history of recurrent ART failure and high response. A total of 40 hyper-responder patients with history of previous ART failure were included. Group I consisted of 22 patients that underwent LOD prior to ART. Group II consisted of 18 patients that underwent only ART. Cycle outcomes of groups were compared. Following LOD, significant reduction in AMH levels were detected in group I (4.75 ng/mL to 2.25 ng/mL). Clinical pregnancies were similar among groups (40% versus 27.8% p = 0.65). There was no cycle cancellation in Group I, whereas there were three cycle cancellations observed due to OHSS in Group II. Our results indicate that LOD might offer enhanced fertility outcomes and may reduce the likelihood of cycle cancellations in hyper-responders with previous ART failures.

Perinatal outcomes of idiopathic polyhydramnios.

OBJECTIVE: To investigate the perinatal outcomes of cases with idiopathic polyhydramnios. STUDY DESIGN: Retrospective analysis of 160 singleton pregnancies that were under routine surveillance at the department of obstetrics from 2008 to 2010 was performed to assess perinatal outcomes. Finally, 59 cases were included as idiopathic polyhydramnios, and 101 cases were included as controls. Preterm delivery (<37 weeks), gestational age at birth, low birth weight (<2500 g), very low birth weight (<1500 g), macrosomia (>4000 g), 1- and 5-min APGAR scores <7, small for gestational age (SGA) fetuses, large for gestational age (LGA) fetuses, C-section rates, number of fetal distress, admission to neonatal intensive care unit (NICU) after delivery, neonatal death within the first 7 days, and deaths before the age of 1 year were selected as perinatal outcome variables. RESULT: Significantly higher preterm labors and low 1- and 5-min APGAR scores were noted in the idiopathic polyhydramnios group compared with the control group. CONCLUSION: Although perinatal outcomes are conflicting in literature, idiopathic polyhydramnios warrants close surveillance especially near term.

Recurrent massive hemoperitoneum due to ovulation as a clinical sign in congenital afibrinogenemia.

Massive hemoperitoneum due to ovulation is a rare but serious and life-threatening complication for women with coagulation disorders, and may lead to surgical interventions and even oophorectomy. Congenital afibrinogenemia is an uncommon coagulation disorder usually discovered during childhood. Intraabdominal bleeding due to ovulation is very rare in these patients and only a few cases of corpus luteum rupture and hemoperitoneum in afibrinogenemic patients have been described. In all women, the diagnosis was known since childhood. We report on a 24-year-old woman with congenital afibrinogenemia with recurrent massive intraabdominal bleeding due to ovulation as the presenting clinical sign. Exploratory laparotomy and excision of the ruptured follicle was performed at the first bleeding episode; the second episode was managed with fresh frozen plasma and blood transfusions. Conservative management is crucial for these patients. If surgery cannot be avoided, a conservative surgical approach should be chosen to preserve ovarian function.
