RESUMO
This study was based on the pathophysiology of the disease and aimed at predicting ovarian hyperstimulation syndrome (OHSS) by determining the importance of ratios obtained from the inflammatory process associated with oestradiol and progesterone in recent years. Out of 242 infertile women who underwent assisted reproductive therapy, 59 patients who developed OHSS were taken as the study group, while the remaining 122 normo-responder (NR) and 61 hyper-responder (HR) patients constituted the control group. The neutrophil to lymphocyte (NLR) and oestradiol/progesterone (EPR) ratios were found to be statistically significantly higher in the OHSS group (P <0.001). A multivariate logistic regression analysis revealed that the NLR (OR=2.410, P =0.001) and EPR (OR=1.701, P =0.028) were independent predictors for the development of OHSS. In conclusion, in OHSS inadequate progesterone levels may inhibit suppression of the exaggerated inflammatory process caused by high E2 levels, and NLR and EPR can be used to predict the development of OHSS in patients undergoing controlled ovarian hyperstimulation during in vitro fertilisation cycles.

OBJECTIVE: To investigate the effect of hCG day estradiol (hCG-E2) used in Down Syndrome screening on maternal serum levels of PAPP-A in fresh in vitro fertilization (IVF) cycles. METHODS: This study was a retrospective analysis of a cohort that resulted in a single pregnancy after a total of 92 fresh IVF cycles. The primary outcome of this study was to determine the effect of fresh IVF cycle parameters on the PAPP-A level and the cutoff value for hCG-E2 predicting a low PAPP-A level, while the secondary outcome was to determine whether the effect of IVF parameters on the PAPP-A level was significant. RESULTS: There was a negative correlation between PAPP-A levels and the number of hCG-E2 and grade 1 embryos (respectively, p = .049; .047), while a positive correlation was observed between baby weight at birth and the PAPP-A (p < .05). At a PAPP-A value of 0.82, the difference between the two groups, in terms of hCG-E2, the number of grade 1 embryos, and pregnancy-related complications was significant (p = .050; .029; .033, respectively). The threshold value of hCG-E2 affecting PAPP-A levels was statistically significant (AUC = 0.618; p = .050; hCG-E2 = 4869.5 pg/ml). In the model, an increase in the number of grade 1 embryos resulted in higher PAPP-A levels (OR = 2.26; p = .044). CONCLUSION: The fact that the hCG-E2 cutoff value, which lowers PAPP-A, reflects excessive ovarian stimulation argues for the correction of the dual screening test in a subset of patients with high response to the first-trimester screening test.

RESEARCH QUESTION: Do bisphenol A (BPA) levels in maternal urine, serum and follicular fluid affect embryo quality and intracytoplasmic sperm hinjection (ICSI) cycle outcomes in women with unexplained infertility? DESIGN: Prospective study conducted between 1 April 2019 and 30 September 2019. The study cohort consisted of 82 women aged between 23 and 33 years who underwent intracytoplasmic sperm injection owing to unexplained infertility and provided urine, blood and follicular fluid samples on the day of oocyte retrieval. Consumption of drinking water from plastic carboys or bottles at home were considered as chronic BPA exposure. Demographic features and IVF outcomes of the patients were collected. RESULTS: Among the 82 women with unexplained infertility, clinical pregnancy was achieved in 22 (26.8%) patients after the IVF and embryo transfer cycle. The patients who consumed tap water had statistically significantly lower BPA values in three body fluids compared with patients who consumed plastic bottled water (all P < 0.001). Women who had grade 1 embryos transferred had lower serum BPA values than women who had grade 2 embryos transferred (10.8 ± 5.2 versus 26.9 ± 22 ng/ml, Pâ¯=â¯0.003). Serum and follicular fluid BPA levels were statistically significantly higher in women who failed to achieve clinical pregnancy (P < 0.001, Pâ¯=â¯0.006, respectively) and obtain a live birth (both Pâ¯=â¯0.007). CONCLUSIONS: A negative relationship was found between serum and follicular fluid BPA levels and embryo quality, clinical pregnancy and live birth in these women. In addition, the BPA levels of women who consume tap water at home were lower than those who use plastic bottled water.

Background/aim: Diminished ovarian reserve (DOR) represents a major challenge in reproductive medicine, as it is often associated with poor ovarian stimulation response, high cycle cancellation rate, and low pregnancy rate. The aim of the present study is to compare the clinical pregnancy rates in intracytoplasmic sperm injection-embryo transfer (ICSI-ET) cycles in patients with different DOR etiologies. Materials and methods: Patient data were recorded with a computer-based program called Success Estimation Using a Ranking Algorithm (SERA). Overall, 459 patients were divided into 3 groups according to their DOR etiologies (Group A: idiopathic, n = 81; Group B: age-related, n = 294; Group C: previous ovarian surgery, n = 84). Results: Out of 459 stimulation cycles, 378 (82.4%) reached the oocyte retrieval stage, while 201 (43.8%) had embryo transfers. There was no significant difference between the patients with different DOR etiologies in terms of embryo transfer and cycle cancellation rate. The patients who had embryo transfer were 44 (52.4%) in Group A, 38 (46.9%) in Group B, and 119 (40.5%) in Group C. There were no significant differences between the three groups (P = 0.114). The percentages of women who had oocyte retrieval were 84.5% in Group A, 70% in Group B, and 80.3% in Group C (P = 0.104). While clinical pregnancy per transfer was 35.8% in Group A, 19.8% in Group B, and 29.5% in Group C, there was no statistically significant difference between the groups (P = 0.113) Conclusion: Although ovulation induction and ICSI-ET outcomes, including clinical pregnancy and live birth rates, were not significantly different with regards to the etiology of DOR, young women with DOR may benefit from assisted reproductive techniques.

One hundred and seventy-two twin-pregnant patients were enrolled. The estimated foetal weight was calculated using 19 different formulas. Ong's formula (0.954 (95%CI = 0.938/0.966)), which was designed specifically for twins, produced the highest Cronbach's alpha value followed by Hadlock II (0.952 (95%CI = 0.935/0.965)), Hadlock I (0.952 (95%CI = 0.935/0.964)), Hadlock III (0.952 (95%CI = 0.935/0.964)), Hadlock IV (0.952 (95%CI = 0.935/0.964)) and our formula (0.952 (95%CI = 0.935/0.964)), which produced the same Cronbach's alpha values for twin A. For twin B, our formula produced the highest Cronbach's alpha value (0.961 (95%CI = 0.948/0.972) followed by Hadlock II (0.960 (95%CI = 0.946/0.971)), Hadlock I (0.960 (95%CI = 0.946/0.970)), Hadlock III (0.960 (95%CI = 0.946/0.970)) and Hadlock IV (0.960 (95%CI = 0.946/0.970)). In conclusion, our formula (AC, FL) performed well in predicting the foetal weights in twin pregnancies (>24 weeks) in our study. However, it should be tested in other populations. Hadlock II (AC, FL) produced a comparable performance to Hadlock I (BPD, HC, AC, FL), Hadlock III (BPD, AC, FL) and Hadlock IV (HC, AC, FL). Hadlock II may be preferable in twin pregnancies since it is based on AC and FL only.

This study investigated the association of blood and semen Bisphenol A (BPA) levels of the male partner on the reproductive outcome in intracytoplasmic sperm injection (ICSI) treatment cycles. For this prospective study (ClinicalTrials.gov identifier: NCT02703584), blood and semen samples of the male partner of the 75 women who had ICSI were analyzed. The study group consisted of men who had ICSI for male factor infertility other than azoospermia, while men with normal spermiogram whose partners underwent ICSI due to tubal factor infertility were taken as the study group. Habitual consumption of drinking water from plastic carboys/bottles (PBW) at home was also questioned in both groups as it was considered as chronic BPA exposure. The association of ICSI outcome with blood BPA (bBPA) and semen BPA (sBPA) levels was analyzed in both groups. No significant correlation was found between sperm parameters and bBPA levels in both groups. A negative correlation was found between sBPA levels and total sperm count and progressive sperm motility in men who consumed PBW. Embryo development arrest was found to be significantly higher in patients who have high sBPA levels. Although sBPA levels were not different in PBW consumers, bBPA levels were found to be significantly lower in those who consumed tap water (TW) than those who used PBW. Elevated bBPA were associated with a significant decrease in clinical pregnancy rate. Considering the widespread human exposure to BPA, the effect of BPA on the male reproductive system needs to be further examined.

Background: The studies which investigated the relationship between anti-Mullerian hormone (AMH) level and abortion rate have conflicting results. Aims: This retrospective study aimed to evaluate the relationship between AMH levels and abortion in women who achieved pregnancy with in vitro fertilisation (IVF) treatment. Settings and Design: This retrospective study was conducted in the Department of Gynecology and Obstetrics, Etlik Zubeyde Hanim Women's Health Training and Research Hospital, between January 2014 and January 2020. Materials and Methods: Patients below 40 years of age who conceived after IVF-embryo transfer treatment during a 6-year period and had a serum AMH level measurement were included. The patients were divided into three groups according to the serum AMH levels as low AMH (L-AMH, ≤1.6 ng/mL), intermediate AMH (I-AMH, 1.61-5.6 ng/mL) and high AMH (H-AMH, >5.6 ng/mL). The groups were compared in terms of obstetric, treatment cycle characteristics and abortion rates. Statistical Analysis Used: The Mann-Whitney U-test was used in comparison of non-parametric data of two groups; the Kruskal-Wallis test was used to compare the data of more than two groups. When a statistically significant difference was found in the Kruskal-Wallis test result, the groups were compared in pairs using the Mann-Whitney U-test, and the groups that made a statistical difference were determined. The Pearson's Chi-square and Fisher's exact tests were used to compare the independent categorical variables. Results: L-AMH (n = 164), I-AMH (n = 153) and H-AMH (n = 59) groups were similar in terms of obstetric histories and number of cycles applied, with an abortion rate of 23.8%, 19.6% and 16.9%, respectively (P = 0.466). The same analyses were repeated in two subgroups under 34 years of age and above, and no difference was found in terms of miscarriage rates. The number of oocytes retrieved and the number of mature oocytes were higher in H-AMH group compared to intermediate and low groups. Conclusion: No relationship was found between serum AMH level and abortion rate in women who achieved clinical pregnancy with IVF treatment.
RESUMO
OBJECTIVES: To investigate the effect of human chorionic gonadotropin day progesterone (hCG-P) level on pregnancy outcomes in in vitro fertilization (IVF) cycles. MATERIAL AND METHODS: This study is an analysis of a cohort of 1318 fresh IVF- embryo transfer cycles, including 579 agonists and 739 antagonists, performed at a single IVF center between 2007 and 2018. For fresh cycles, we performed Receiver Operating Characteristic analysis (ROC) to calculate the threshold value of hCG-P, which affects pregnancy outcomes. We divided patients below and above the determined threshold value into two groups, then, correlation analysis and we performed logistic regression analysis. RESULTS: According to ROC curve analysis of hCG-P,AUC was 0.537 (95% CI: 0.510-0.564, p < 0.05) for LBR, and the threshold value for P was 0.78. The hCG-P threshold value of 0.78 proved to be significant in relation to BMI, type of drug used during induction, the hCG day E2, the total number of oocytes, the number of oocytes and the subsequent pregnancy outcome between the two groups (p < 0.05). However, the model we built, which accounted for hCG-P, total number of oocytes, age, BMI, induction protocol, total dose of gonadotropin used in induction did not prove significant in terms of its effect on LBR. CONCLUSIONS: The threshold value of hCG-P that we found to have an effect on LBR was quite low compared with the P-value generally recommended in the literature. Therefore, further studies are needed to determine an accurate P-value that reduces success in managing fresh cycles.
RESUMO
Objective: This study aimed to evaluate the effect of the rate of decline in serum estradiol (E2) levels between hCG injection and the day of embryo transfer (ET) on the success of assisted reproductive technology (ART) in women with infertility of different etiologies. Materials and Methods: Women 20-45 years of age who underwent a standard GnRH antagonist or long agonist protocol and fresh ET during day 3 of their first ART cycle were included. Group 1 was diagnosed with low ovarian reserve, group 2 comprised high ovarian responders, and group 3 consisted of normal responders. Both groups were divided into four subgroups according to the decrease in E2 levels between the day of hCG injection and the day of ET. Subgroup A patients had a decrease of <20%, subgroup B a decrease of 20-40%, subgroup C a decrease of 41-60%, and subgroup D a decrease >60%. The primary outcome measure was the effect of an E2 decline, based on the measurement of E2 on the day of hCG administration and day of ET, on the implantation rate. The secondary outcome was the change in E2 values in these three groups. Results: The study was conducted on 1.928 women. Of these, 639 were poor responders (group 1), 502 were high responders (group 2), and 787 women had a normal ovarian response (group 3). Patients with a 60% decrease in their E2 levels on the ET day after hCG had a lower live birth rate (LBR) and higher miscarriage rate (MCR), except normoresponders, in whom a similar decline was significant only with respect to MCR. Conclusion: We indicate that high ovarian responders who underwent fresh ET cycles with a 60% decrease in their E2 levels on the ET day after human chorionic gonadotropin had lower LBRs and higher miscarriage. However, in normoresponder women, this decline was only significant in miscarriage.
RESUMO
Objective: Ceramide (CER) is a bioactive component of the mitochondrial membrane. In this study, we will investigate the clinical importance of serum CER (sCER) and follicular fluid CER (ffCER) levels in the lipid synthesis pathway and their effect on poor oocyte quality and in vitro fertilization (IVF) outcome. Materials and Methods: This cross-sectional, case-control study was conducted in the IVF unit of a maternity hospital in the capital of Turkey, Ankara. A total of 88 women undergoing their first IVF cycle were included in this study patients were divided into 2 groups according to current diagnostic criteria for their ovarian reserves. Baseline sCER levels, and ffCER concentrations retrieved on the oocyte pickup day were measured. Results: The mean age, body mass index, and infertility duration of the patients was similar between the groups (all p>0.05). There was also no significant difference in the clinical pregnancy rates (38.6% vs. 47.7%, p=0.127). sCER (15.6±6.5 vs. 23.5±8.9) and ffCER (82.5±34.3 vs. 116.4±46.5) levels were statistically significantly lower in the low ovarian reserve (LOR) group (both p<0.001). The performed receiver operating characteristic curve analysis revealed that sCER and ffCER levels could predict both LOR and pregnancy. Conclusion: This is the first study evaluating the sCER and ffCER levels of patients undergoing IVF treatment. CER may be used as an ovarian reserve markers and a biomarker capable of predicting IVF outcomes.
RESUMO
Objective: Assisted hatching (AH) techniques can improve live birth (LB) and clinical pregnancy (CP) rates. Since there are limited data regarding this subject, we investigated the impact of laser-assisted hatching (LAH) on fresh embryo transfer (ET) and association with pregnancy outcomes in unselected patient population. Materials and Methods: This retrospective study included the fresh ETs performed at our center between April 2010 and April 2019. Among 3.782 fresh ETs, 3.286 underwent LAH (n=1.583 at cleavage stage and n=1.703 at blastocyst stage) while 496 underwent non-assisted hatching (NAH) (n=213 at cleavage stage and n=283 at blastocyst stage). The ETs were performed at the blastocyst or cleavage stages, and single or double embryos were transferred. LB rate was the primary outcome, while secondary outcomes were the pregnancy test, monozygotic twinning (MZT), and CP rates. Results: The LAH and NAH groups showed similar LB, pregnancy test, CP, and MZT rates at cleavage and blastocyst stages. On the other hand, LAH significantly affected LB rates at the blastocyst stage (20.6% at blastocyst stage vs. 16% at the cleavage stage, p=0.001). Conclusion: In conclusion, LAH does not improve reproductive outcomes of fresh blastocyst-stage and cleavage-stage ETs. However, LAH significant impacts LB rates in the blastocyst stage than the cleavage stage.
RESUMO
OBJECTIVES: To compare the success of two controlled ovarian hyperstimulation protocols; rFSHâ +â hp-hMG with only rFSH in the GnRH antagonist protocol in diminished ovarian reserve under 35 years of age. MATERIAL AND METHODS: Data from January 2015 to June 2019 were abstracted from the hospital records of IVF Clinic. The women younger than 35 years of age who were diagnosed as diminished ovarian reserve and underwent standard GnRH antagonist protocol were included. Patients in Group-1 underwent controlled ovarian stimulation with rFSH alone and Group-2 with rFSH in combination with hp-hMG. Patients in both groups were divided into three subgroups according to their antral follicle count at Day 3:â < 4 (a), 4-6 (b), and 7-10 (c). Demographic features and IVF outcomes of the patients were extracted. RESULTS: Total number of retrieved oocytes, was higher in Group-1 than Group-2 (6.5â ±â 2.1 vs 5.5â ±â 2.3, respectively, p <â 0.001). However, there were no significant differences between the two groups in terms of clinical pregnancy rate, implantation rate, miscarriage rate and live birth rate. Although the main study outcome parameters did not show significant difference between Group-1a and Group-2a, the number of mature oocytes (5â ±â 2.8 vs 1.8â ±â 1.2, respectively, p = 0.006) was higher in Group-1a. CONCLUSIONS: We observed no beneficial effect of LH supplementation during IVF for the treatment of women under 35 years old with diminished ovarian reserve in the first treatment cycle when compared with rFSH only in the antagonist protocols.
RESUMO
INTRODUCTION: To create a scoring system by including all of the factors that are recommended for an ideal ET and to investigate its correlation with the Β-HCG results. MATERIALS AND METHODS: This study was conducted as a retrospective trial between January 2009 and December 2018. Women who had a single ET between the specified dates were included in the study. The embryo grade, ET day, distance between the fundus to embryo transfer site measured via ultrasonography, endometrial thickness on ET day, and presence of mucus and blood in the catheter after transfer were the variables evaluated. Each one of the five variables that constituted the scoring system were rated separately. RESULTS: Overall, 1652 patients participated in this research. Antral follicle count (13,3 ± 8 vs. 14,6 ± 8,2, p: 0,001), endometrial thickness on the ET day (9.9 ± 2 vs.10.3 ± 2, p = 0.006) and number of mature oocytes (8.6 ± 6 vs. 9 ± 5.1, p: 0.003) were significantly higher in patients with positive Β-HCG values. The total score in the Β-HCG positive group was 9.8 ± 1.4 versus 8.9 ± 1.4 in the Β-HCG negative group (p < 0.001). The best ETSS cut-off value for predicting Β-HCG positivity was 9.5, with 82% sensitivity and 67% specificity (AUC:0.808). CONCLUSION: Our scoring system is an important step toward standardization, as it offers a new, practical, cost-free, and applicable scoring system based on pre- and post-ET measurements and laboratory data.

AIM: Whether to use the same ovarian stimulation protocol or change it after a failed in vitro fertilization cycle is still a controversial issue. In this study we aimed to investigate the effect of changing the stimulation protocol in the sequental cycle of the same patient population on intracytoplasmic sperm injection (ICSI) outcomes. METHODS: This retrospective study included two sequental fresh ICSI cycles of 941 infertile women attended in a period of one year. Group A was composed of patients who failed to have clinical pregnancy with a GnRH agonist and group B was composed of patients who failed to have clinical pregnancy with a GnRH antagonist protocol cycle. In both groups the study group was composed of patients whose stimulation protocol was changed in the sequential cycle and the control group was composed of patients who proceeded with the same stimulation protocol. The clinical pregnancy and live birth rates were primary outcomes. RESULTS: In group A, the clinical pregnancy rates were comparable between the study and the control groups, but the live birth rate was higher in the study group (p=0.03). In group B, there was no difference in terms of clinical pregnancy and live birth rates between the study and control groups (p=0.740 and p=0.842 respectively). CONCLUSIONS: Changing the ovarian stimulation protocol after a failed ICSI cycle downregulated with a GnRH agonist increased the live birth rate. After a failed cycle stimulated with a GnRH antagonist protocol, protocol change did not have any impact on the clinical pregnancy and live birth rates.

Background The number and the quality of embryos transferred are important predictors of success in in vitro fertilization (IVF) cycles. In the presence of more than one good quality embryo on the transfer day, double-embryo transfer (DET) can be performed with these embryos, but generally, different quality embryos are present in the available transfer cohort. We aimed to investigate the effect of transferring a poor quality embryo along with a good quality embryo on IVF outcomes. Methods In this study, 2298 fresh IVF/intracytoplasmic sperm injection (ICSI) cycles with two good quality embryos (group A), one good and one poor quality embryo (group B), and single good quality embryo (group C) transfers were examined. All groups were divided into two subgroups according to the transfer day as cleavage or blastocyst stage. Clinical pregnancy and live birth rates were the primary outcomes. Results In the cleavage stage transfer subgroups, the clinical pregnancy rates were lower in the single-embryo transfer (SET) subgroup compared with DET subgroups, but the difference was not statistically significant compared with DET with mixed quality embryos. The live birth rates were comparable between the three groups. In the blastocyst transfer subgroups, the clinical pregnancy and live birth rates were significantly higher in DET with two good quality embryos than DET with mixed quality embryos and SET groups. Multiple pregnancy rates were higher in both DET groups in terms of transfer day (p = 0.001). Conclusion DET with mixed quality embryos results with lower clinical pregnancy and live birth rates compared with DET with two good quality embryos at the blastocyst stage. At cleavage stage transfer, there is no difference in live birth rates between the two groups.
RESUMO
OBJECTIVE: To investigate the correlation between sonographic, hysteroscopic, and pathological findings in postmenopausal asymptomatic patients with sonographically thickened endometrium. METHODS: The records of postmenopausal patients who attended the Menopause Outpatient Clinic of a tertiary women's hospital in Ankara, Turkey between January 1, 2012 and December 15, 2013 were retrieved. A total of 266 postmenopausal women without vaginal bleeding underwent hysteroscopic evaluation and endometrial sampling. Patients whose pathological records indicated an endometrial thickness equal to or greater than 6 mm (double layer) on transvaginal ultrasonography without any symptoms were included in the study. RESULTS: The most frequently detected focal intrauterine lesions in asymptomatic women were endometrial polyps, which were diagnosed in 168 (63.1%) cases. Twenty-four (9%) patients were diagnosed as having simple hyperplasia, 4 (1%) atypical hyperplasia, and 8 (3%) endometrial adenocarcinoma. Two of the patients with adenocarcinoma were diagnosed based on endometrial polyps, and 6 cases showed endometrial hyperplasia on hysteroscopy, while histological examination showed endometrial carcinoma. CONCLUSION: We suggest 10.5 mm as the cutoff value for endometrial thickness and recommend hysteroscopy following dilatation and curettage to increase diagnostic efficacy and provide definitive treatment in asymptomatic postmenopausal women with thickened endometrium.
