Evaluation of Clinical Outcomes after Poor-Quality Embryo Transfer and Prognostic Parameters.

We aimed to investigate the clinical results following poor-quality embryo transfer and the parameters to foresee the prognosis. In this study, 2123 cycles that had day 3 and day 5 single-fresh embryo with poor-quality embryo transfers and good-quality embryo transfers were compared. The cycles according to transfer day were evaluated by conducting a subgroup analysis. The correlation between all the obtained demographic characteristics, controlled ovarian stimulation parameters, and cycle results were analysed. Clinical pregnancy was established in 53 patients that underwent transfer in the poor-quality embryo group (14.9%). Of these patients, 36 had live birth (live birth rate per clinical pregnancy 67.9%). In cleavage-stage embryos, live birth rates per clinical pregnancy were higher in poor-quality blastocyst transfer. When analysing the factors affecting live births in the poor-quality embryo group, as the total gonadotropin dose increases, the probability of live birth decreases, as in the probability of hCG positivity. In conclusion, although the probability of pregnancy is low, when clinical pregnancy is established, there is a high chance of having a live birth after poor-quality embryo transfers. This could be regarded as an acceptable option in cycles when only poor-quality embryos are available.

Early or late response in poor responders: does it make a difference in cycle outcome?

Ovarian response to stimulation mainly determines the length of stimulation. However, there is no clarity in the literature regarding the optimal duration required to achieve oocyte maturity in patients with the poor ovarian response (POR) defined by Bologna criteria. Therefore, a total of 267 cycles that fulfilled the inclusion criteria were selected retrospectively. Group A constitute of patients with a stimulation period < 9 d (n = 70); and group B included patients with a stimulation period ≥ 9 d (n = 133). The results showed that antral follicle count (5.72 ± 1.82 vs. 5.10 ± 1.78, p = 0.023), serum oestradiol level on hCG day (1286.88 ± 778.18 pg/mL vs. 820.14 ± 479.04 pg/mL, p = 0.001), and total gonadotropin dose used (2949.53 ± 727.92 IU vs 2020.94 ± 415.17 IU, p = 0.0001) were higher in group B when compared to group A. Although the number of total (5.47 ± 3.32 vs 3.86 ± 2.15, p = 0.0001) and mature oocytes retrieved (4.34 ± 2.88 vs 2.84 ± 1.67, p = 0.0001) were higher in group B, no significant difference was observed in the pregnancy rates between groups (25.6 vs 15.7%, p > 0.05). In conclusion, no deleterious effect of a shorter duration of stimulation on cycle outcome was seen in patients with POR.

Serum and Follicular Fluid Thiol/Disulfide Homeostasis in Diminished Ovarian Reserve Patients Undergoing In Vitro Fertilization/Intracytoplasmic Sperm Injection Treatment.

INTRODUCTION: The etiologies of diminished ovarian reserve (DOR) are still poorly understood, and many factors such as age, autoimmunity, genetics, idiopathicity, iatrogenesis, and oxidative stress (OS) play a role. Oxidative cellular damage increases following reactive oxygen species (ROS)-induced aging. This is the first study to evaluate the serum and follicular fluid (FF) thiol/disulfide homeostasis in patients under 35 years of age with DOR undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). METHODS: In this study, DOR was defined by the Poseidon criteria, and Poseidon group 3 women were selected as the study group (n = 40). The control group was composed of patients with the diagnosis of mild-moderate male factor infertility (n = 30). RESULTS: The FF and serum native and total thiol levels, the markers of the antioxidant system, were significantly decreased in the DOR group compared with the control group (p = 0.021) (p = 0.037) (p = 0.029) (p = 0.04). On the other hand, we found no significant differences in the oxidant parameters between the groups (p > 0.05). CONCLUSIONS: An intrinsic deficiency of antioxidants can play an important role in the etiology of DOR. The dietary addition of antioxidants could be beneficial in DOR patients.

Evaluation of Dysfunctional HDL by Myeloperoxidase/Paraoxonase Ratio in Unexplained Infertility Patients Undergoing IVF/ICSI.

The relationship between oxidative stress and unexplained infertility (UEI) has not been studied in detail. This is the first study to evaluate dysfunctional high-density lipoprotein (HDL) by the myeloperoxidase (MPO) and paraoxonase (PON) ratio to investigate the role of oxidative stress in UEI. MATERIALS AND METHODS: Patients with UEI (study group, n = 40) and male factor infertility (control group, n = 36) were included in this prospective study. Demographics and laboratory assessments were analyzed. RESULTS: Total dosages of gonadotropin were higher in UEI when compared to the control group (p = 0.033). Number of Grade 1 embryos and the quality of blastocysts were lower in UEI than in the control group (p = 0.024, p = 0.020, respectively), whereas serum MPO/PON ratio was higher in UEI (p = 0.042). Stepwise linear regression analysis revealed that serum MPO/PON ratio levels could significantly predict the duration of infertility (p = 0.012). CONCLUSIONS: Serum MPO/PON ratio increased in patients with UEI, whereas the number of Grade 1 embryos and the quality of blastocysts decreased. Similar clinical pregnacy rates were found in both groups but the ET on day five is associated with higher clinical pregnancy rate in the male factor infertility.

Comparison of the impact of laser-assisted hatching on fresh cleavage and blastocyst embryo transfer and association with pregnancy outcomes.

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.

The role of FSH to AMH ratio in poor prognosis patients undergoing ICSI cycle

Objective: The objective of this study was to estimate the number of oocyte retrieval and cycle cancellation using follicle stimulating hormone (FSH) to anti-Mullerian hormone (AMH) ratio in poor prognosis patients undergoing intracytoplasmic sperm injection treatment. Material and Methods: This retrospective study including fresh cycles was conducted in Zekai Tahir Burak Women's Health Training and Research Hospital, between January 2015 and October 2018. Women aged between 24 and 44 years were recruited and the baseline serum hormone levels, FSH/AMH ratio, and the antral follicle count were recorded. Number of retrieved oocytes, metaphase-II oocytes, fertilised oocytes, and the number and grade of the embryos were also recorded. Results: A total of 108 cycles, corresponding to 92 women with poor prognosis were eligible for analysis. The use of FSH/AMH ratio performed well in predicting retrieved oocyte count <5 with an area under the curve (AUC) of 0.82 [95% confidence interval (CI): 0.71-0.92]. A FSH/AMH ratio cut-off of 11.36 was set for the retrieval of <5 oocyte at oocyte pick-up (OPU) with 80% sensitivity and 87% specificity. The FSH/AMH cut-off value was 14.22 to differentiate cycle cancellation and no oocyte retrieval at OPU, with a sensitivity of 91% and a specificity of 44% (AUC of 0.71; 95% CI: 0.59-0.83). There was no correlation between FSH/AMH ratio and clinical pregnancy. Conclusion: The assessment of this simple ratio at the beginning of the cycle may help clinicians better anticipate gonadotropin stimulation treatment and better counsel patients about cycle cancellation and the expected oocyte yield.

Does Coronavirus Disease-19 Infection Affect Ovarian Reserve in Infertile Women? A Retrospective Study.

Background: Previous studies have revealed menstrual changes following coronavirus disease-19 (COVID-19) disease. The potential impact of COVID-19 on female reproductive organs, ovary in particular, has not been investigated thoroughly. Aims: The aim of this study was to evaluate changes in serum levels of follicle-stimulating hormone (FSH), luteinising hormone (LH) and oestradiol (E2) following COVID-19 disease as a surrogate for the detection of ovarian vulnerability to SARS-CoV-2 infection. Settings and Design: In this retrospective study, hospital records of unexplained infertile women between 21 and 40 years old who have attended our institution's reproductive medicine unit for evaluation and/or treatment of infertility have been evaluated. Materials and Methods: Menstrual cycle day 2-5 serum follicle-stimulating hormone, luteinising hormone and E2 levels of 28 infertile women have been studied both before and after the COVID-19 disease to evaluate ovarian reserve before the ovulation induction treatment cycle. Statistical Analysis Used: The demographic characteristics and hormonal results of these 28 unexplained infertile women have been compared. The Shapiro-Wilk test has been used to evaluate the normal distribution of variables. Comparison of ovarian reserve markers which were established before and after COVID-19 infection has been performed using paired samples t-test. Results: All patients except one have shown mild COVID-19 symptoms and their infection courses have resulted in uneventful recovery. Serum FSH, LH and E2 levels of 24 (85%) and serum anti-Müllerian hormone (AMH) levels of 4 (15%) patients have been evaluated before and after COVID-19 disease is statistically similar. Conclusion: COVID-19 disease or inflammatory response of the infection itself does not seem to affect pituitary gonadotropins and ovarian hormones in infertile women based on menstrual cycle day 2-5 serum FSH, LH, E2 and AMH levels. Further studies including higher patient numbers are urgently needed to clarify the potential effects of COVID-19 disease on the gonadal function of women.

The relationship between good quality embryo rates and IVF outcomes/embryo transfer policies in extended embryo culture.

This study aims to investigate which parameters affect the change in good quality embryo rates during the cleavage stage and whether they have any effect on embryo transfer policies and IVF results. We analysed changes in good quality embryo (grades 1 and 2) rates during the period on days 2, 3 and 5; patients with five or fewer embryos (group 1), 6-10 embryos (group 2) and more than 10 embryos (group 3). The good quality embryo rates decreased in all groups on day 5. When the infertility reasons are studied among all of the groups, ovulatory dysfunction is found to be significantly higher in group 2 compared to group 1 and unexplained infertility was found to be significantly higher in group 2 compared to group 1 and group 3. Total antral follicle, mature oocyte and total oocyte counts were found to be significantly lower in group 1. However, there is no significant difference found among all of the groups for ß-HCG levels and clinical pregnancies. Changes in good quality embryo rates at the cleavage stage in extended embryo culture do not have an impact on IVF results.IMPACT STATEMENTWhat is already known on this subject? The number and quality of embryos in the cleavage stage are important parameters affecting the embryo transfer decision on day 5. There is still insufficient knowledge concerning changes in the percentage of increased good quality embryo transfers associated with IVF outcomes during the second to the third day, and the third to the fifth day.What do the results of this study add? Day 5 embryo transfer is possible in patients with a low number of embryos, according to our results. The good quality embryo rates of patients with a low number of embryos at the cleavage stage are more promising compared to patients having more than five embryos.What are the implications of these findings for clinical practice and/or further research? An extended embryo culture option can be used on patients with a low number of embryos for clinical practice.

Effect of Antagonist Start Day on Cycle Outcomes in Poor Responders.

BACKGROUND: Despite the great advances in Assisted Reproductive Technologies (ART), management of poor responders has remained a great challenge. Gonadotropin releasing hormone antagonist (GnRH-ant) has been offered as a patient friendly protocol. In the literature, conflicting data exists about the effect of the GnRH-ant starting day on cycle outcomes. AIM: The aim of this study is to evaluate the effect of GnRH-ant starting day on cycle outcomes of patients with poor ovarian response defined by Bologna criteria. SETTING AND DESIGN: This retrospective cohort study was conducted at an ART clinic of a tertiary hospital. MATERIALS AND METHODS: A total of 361 cycles using flexible GnRH-ant, 195 in Group A (GnRH-ant administered before day 6 of stimulation) and 166 cycles in Group B (GnRH-ant started on or after day 6), were selected retrospectively for the study. STATISTICAL ANALYSIS: Statistical analysis of data was carried out using using IBM SPSS Statistics Software (20.0, SPSS Inc., Chicago, IL, USA). Independent samples t-test and Mann-Whitney U test were used to analyze the variables. RESULTS: Total antral follicle count was significantly higher in Group A compared to Group B (P = 0.009). Duration of stimulation was significantly shorter (P < 0.01) and total dose of gonadotropin used was lower in Group A when compared to Group B (P < 0.01). While higher number of oocytes was retrieved from Group A (P = 0.037), no between-group differences were observed in number of mature oocytes, fertilized oocytes, clinical pregnancy rate or ongoing pregnancy rate (OPR) per embryo transfer (P > 0.05). CONCLUSION: Early GnRH-ant start may point out a favourable response to ovarian stimulation in poor responders. However, clinical or OPRs were not different from the late GnRH-ant start group.

The impact of different etiologies of diminished ovarian reserve on pregnancy outcome in IVF-ET cycles

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.

Retrospective comparison of intracytoplasmic sperm injection outcomes of sperm retrieved from a testicular biopsy and freshly ejaculated semen in oligozoospermia / Comparación retrospectiva de los resultados de inyección intracitoplasmática de espermatozoides obtenidos de una biopsia testicular y semen recién eyaculado en oligozoospermia

Objective: The aim of this study was to compare fertilisation, pregnancy rates and perinatal outcomes in patients undergoing intracytoplasmic sperm injection (ICSI) due to oligozoospermia. Methods: A total of 166 patients with oligozoospermia who underwent an ICSI procedure were included in the study. The subjects were divided into two groups according to the sperm retrieval technique used: group 1, ejaculated semen (n=111); group 2, surgical sperm retrieval (n=55). Results: Although the clinical pregnancy rate was lower in group 2, the difference was not statistically significant (36.4% vs. 42.3%, p=0.460). The difference between fertilisation and take-home baby rates of the groups were not significantly different, either (p=0.486, p=0.419, consecutively). Conclusion: Two different sperm retrieval techniques used for ICSI had no statistically significant difference on intracytoplasmic sperm injection outcomes in oligozoospermic patients

Objetivo: El objetivo de este estudio fue comparar la fertilización, las tasas de embarazo y los resultados perinatales en pacientes sometidos a inyección intracitoplasmática de espermatozoides (ICSI) por oligozoospermia. Métodos: Un total de 166 pacientes con oligozoospermia que se sometieron a un procedimiento ICSI se incluyeron en el estudio. Los sujetos se dividieron en dos grupos según la técnica de recuperación de espermatozoides utilizada: grupo 1, semen eyaculado (n=111); Grupo 2, recuperación quirúrgica de espermatozoides (n=55). Resultados: Aunque la tasa de embarazos clínicos fue menor en el grupo 2, la diferencia no fue estadísticamente significativa (36.4% vs. 42.3%, p=0,460). La diferencia entre las tasas de fecundación y de bebés a domicilio de los grupos tampoco fue significativamente diferente (p=0.486, p=0.419, consecutivamente). Conclusión: Dos diferentes técnicas de recuperación de espermatozoides utilizados para la ICSI no tenía ninguna diferencia estadísticamente significativa en la inyección de espermatozoides intracitoplasmáticos resultados en pacientes oligozoospermicos

Value of Post-transfer Day-12 Beta Human Chorionic Gonadotropin Levels for Pregnancy Outcome Prediction of Intracytoplasmic Sperm Injection Cycles.

BACKGROUND: Several markers were studied previously in order to predict the pregnancy outcome of assisted reproductive techniques; however, serum beta human chorionic gonadotropin was found to be the most predictive marker. AIMS: To evaluate the value of serum beta human chorionic gonadotropin levels in discriminating biochemical and clinical pregnancies 12 days after embryo transfer, while determining the factors predicting ongoing pregnancy was established as the secondary aim. STUDY DESIGN: Retrospective cross-sectional study. METHODS: A total of 445 pregnant cycles were retrospectively analysed in 2359 embryo transfer cycles. Patients were divided into two groups according to the outcome of pregnancy: biochemical and clinical. RESULTS: The cut-off value of beta human chorionic gonadotropin levels on day 12 in predicting clinical pregnancies was 86.8 IU/mL with 65.1% sensitivity and 74.7% specificity [CI: 0.76 (0.71-0.81). Receiver operating characteristic curve analysis revealed different cut-off values for embryo transfer days (57 mIU/mL for day 3 embryo transfer CI: 0.59-0.79 and 87 mIU/mL for day 5 embryo transfer, CI: 0.74-0.86). Subgroup analysis of clinical pregnancies revealed a significant difference between ongoing pregnancies and early fetal losses regarding duration of infertility (81.3±54.4 vs. 100.2±62.2 months), serum oestradiol on hCG day (2667.4±1276.4 vs. 2094.6±1260.5 pg/mL), number of transferred embryos (1.9±0.8 vs. 1.5±0.7) and the prevalence of diminished ovarian reserve as an indication (2.3% vs 12.2%). CONCLUSION: Beta human chorionic gonadotropin levels on day 12 following embryo transfer provide an important parameter for the prediction of clinical pregnancy; however, other stimulation parameters are indicated in the prediction of ongoing pregnancies.

Does pituitary suppression affect live birth rate in women with congenital hypogonadotrophic hypogonadism undergoing intra-cytoplasmic sperm injection? A multicenter cohort study.

In this retrospective multicenter cohort study, women with congenital hypogonadotrophic hypogonadism (CHH) (n = 57) who underwent intra-cytoplasmic sperm injection in-between 2010-2014 were compared to age-matched controls with tubal factor infertility (n = 114) to assess ovarian stimulation cycle and pregnancy outcomes. Live birth rates (LBRs) per started cycle were 31.6 and 24.6% in CHH and controls groups, respectively (p = 0.36). Comparable success rates were also confirmed with the logistic regression analysis (OR: 1.44, 95% CI: 0.78-2.67, p = 0.24). Of the 57 women with CHH, 19 were stimulated with the gonadotropin-releasing hormone (GnRH) antagonist protocol, 13 with the long-GnRH-agonist protocol. Pituitary suppression (PS) was not employed in the remaining 25 cases. Compared to women with PS, women without PS had significantly higher embryo implantation rates (21.6 versus 52.6%, p = 0.03). Although there was a trend favoring no PS, LBRs (25.0 versus 40.0%, p = 0.26) per cycle were short of statistical significance. LBRs per cycle (57.1 versus 31.2%, p = 0.11) and miscarriage rates (11.1 versus 16.7%, p = 0.75) were similar between CHH women who were given estrogen + progesterone and progesterone alone to support the luteal phase. In conclusion, the optimal stimulation protocol appears to be exogenous gonadotropin stimulation alone, without PS, and progesterone-only luteal phase support in CHH patients.

Evaluation of time lapse for establishing distal tubal occlusion diagnosis during hysterosalpingography procedure performed by using water soluble contrast media.

BACKGROUND: Hysterosalpingography (HSG) is the most frequently used diagnostic measure for simultaneously determining uterine abnormalities and tubal status among subfertile women. Despite several broader advantages such as availability and increased experience, the subjectivity involved during administration of the HSG procedure itself, and necessary imaging review, decreases the reliability and accuracy of HSG. In this study, we evaluated the time intervals between X-ray imaging during HSG procedure to establish the presence of distal tubal occlusion. METHODS: Our study evaluated the HSG records of 89 women who underwent diagnostic laparoscopy for infertility work-up. Patients who were diagnosed with distal tubal occlusion upon receiving HSG and patients who demonstrated tubal patency on HSG were included in the study, to compare the time intervals in seconds from the tubal visualization view to the last fluoroscopic X-ray shot during the HSG procedure with tubal patency on diagnostic laparoscopy. RESULTS: A statistically significant correlation regarding tubal patency between HSG procedures and diagnostic laparoscopy chromopertubation procedures was demonstrated. Although nearly statistically significant, the interval in seconds between the first HSG imaging and distal tubal filling was shorter for patients with patent tubes on diagnostic laparoscopy than patients with bilateral tubal occlusion (8.4±31.9 and 12.0±19.7, respectively; p=0.057). Time period intervals between the first and the last HSG, and between distal tubal filling to the last HSG of patients with patent tubes on diagnostic laparoscopy and patients with bilateral distal tubal occlusion were found to be statistically similar. CONCLUSION: Although a trend exists towards shorter time period intervals between the first uterine visualization and distal tubal filling graphy among patients with tubal patency, rather than patients with distal tubal occlusion confirmed by diagnostic laparoscopy, clinically reliable objective time period intervals for finalizing the HSG procedure and proceeding with diagnostic laparoscopy due to distal tubal occlusion diagnosis on HSG could not be detected.

BRCA1 and BRCA2 sequence variations detected with next-generation sequencing in patients with premature ovarian insufficiency.

OBJECTIVE: Although the association between BRCA1 and BRCA2 gene mutations and breast and ovarian cancer is known, there is insufficient data about premature ovarian insufficiency (POI). However, several studies have reported that there might be a relationship between POI and BRCA1 and BRCA2 gene mutation. Therefore, in the present study, we aimed to investigate the role of BRCA1 and BRCA2 gene mutations in the etiology of POI in a Turkish population. MATERIAL AND METHODS: The cohort was classified into two groups: a study group, consisting of 56 individuals diagnosed with premature ovarian insufficiency (and who were younger than 40 years of age, had an antral follicle count <3-5, and FSH levels >12 IU/I), and a control group, consisting of 45 fertile individuals. A total of 101 individuals were analyzed by next-generation sequencing to detect BRCA1 and BRCA2 gene mutations. RESULTS: We detected four new variations (p.T1246N and p.R1835Q in BRCA1 and p.I3312V and IVS-7T>A in BRCA2) that had not been reported before. CONCLUSION: We did not find an association between the BRCA1 and BRCA2 gene mutations and premature ovarian insufficiency. However, larger, functional studies are needed to clarify the association.

The impact of unilateral salpingectomy on antral follicle count and ovarian response in ICSI cycles: comparison of contralateral side.

OBJECTIVE: To determine the impact of salpingectomy on the ovarian reserve. Comparisons are made with the contralateral side in patients with unilateral salpingectomy undergoing intracytoplasmic sperm injection (ICSI) cycles. STUDY DESIGN: Patients under 40 with unilateral salpingectomy and without history of ovarian surgery were selected for the multicentre retrospective study. Women with bilateral salpingectomy and history of endometriosis were excluded from the study. Antral follicle count, controlled ovarian hyperstimulation (COH) parameters and number of collected oocytes were the main outcome measures of the study. RESULTS: A total of 56 patients were eligible for this study. The mean age of the patients was 31.6 ± 4.7 years. The reasons for the salpingectomy were hydrosalpinx (39.3%, n = 22) and ruptured ectopic pregnancy (60.7%, n = 34). The ongoing pregnancy rate per embryo transfer was 30.6%. There was no statistically significant difference between the operated and non-operated sides in antral follicle count (AFC), follicles ≥ 17 mm and 10-17 mm on day of human chorionic gonadotrophin (hCG), or number of aspirated oocytes. In the subgroup analysis, AFC, number of growing follicles on day of hCG and number of collected oocytes were comparable between the ectopic pregnancy group and hydrosalpinx group. CONCLUSION: The study suggests that salpingectomy is not associated with detrimental effects on AFC and ovarian response.

Predictivity of mean platelet volume in severe preeclamptic women.

INTRODUCTION: To evaluate the predictive and clinical utilization of the mean platelet volume (MPV) in severe preeclamptic women. MPV is known as platelet size and associated with platelet activation or new platelet synthesis. Platelet count is decreased by vascular endothelial damage in cases of severe preeclampsia. It leads to increased turnover of platelets. METHODS: The severe preeclamptic women with and without preeclampsia during pregnancy were divided into subgroups depending on the gestational birth week early, (<34), late (34-37) preterm birth and term (≥37) gestational weeks. Their MPV was measured 24 hours prior to birth and compared with all subgroups according to the gestational week. RESULT: The study subgroups were performed from early (n = 87), late (n = 48) preterm and term (n = 76) birth with severe preeclampsia, whereas early (n = 69), late (n = 63) and term (n = 228) without gestational hypertensive disorders were recruited in the control subgroups. The MPV of the early, late preterm and term preeclamptic subgroups was statistically higher than that of the control subgroups (9.4 ± 1.3fL vs 8.6 ± 1.2 fL, p < 0.001; 9.5 ± 1.0 fL vs 8.5 ± 0.9 fL, p < 0.001 and 10.2 ± 1.1 fL vs 8.9 ± 1.2 fL, p < 0.001), whereas the mean platelet count of all the study subgroups was significantly lower (237.3 ± 81.3 × 109 /L, 270.0 ± 83.9 × 109/L, p = 0.015; 232.3 ± 80.1 × 109/L vs 268.8 ± 92.7 × 109/L, p < 0.001 and 221.8 ± 70.3.9 × 109/L vs 232.9 ± 82.3 × 109/L, p = 0.03). The sensitivity and specificity of the cut-off MPV for all the subgroups were each less than 80%. CONCLUSION: The MPV may be a predictive marker of severe preeclampsia.

Progesterone change in the late follicular phase affects pregnancy rates both agonist and antagonist protocols in normoresponders: a case-controlled study in ICSI cycles.

OBJECTIVE: The aim of the presented study is to investigate the impact of progesterone change in the late follicular phase on the pregnancy rates of both agonist and antagonist protocols in normoresponders. STUDY DESIGN: A total of 201 normoresponder patients, who underwent embryo transfer were consecutively selected. 118 patients were stimulated using a long luteal GnRH agonist protocol and 83 using a flexible antagonist protocol. The level of change in late follicular phase progesterone was calculated according to the progesterone levels on the hCG day and pre-hCG day (1 or 2 days prior to hCG day) measurement. RESULTS: Clinical pregnancy rates were comparable between long luteal and antagonist group (35.6 and 41%, respectively). The incidence of progesterone elevation on the hCG day was 11% in long luteal and 18% in antagonist group (p = 0.16). In pregnant cycles, p levels both on the hCG day and pre-hCG day measurement were significantly higher in antagonist than agonist cycles (p = 0.029, p = 0.038, respectively). The change of p level was statistically significant in non-pregnant cycles both for the agonist (-0.17 ± 0.07; 95% CI: -0.29 to -0.37) and antagonist groups (-0.18 ± 0.07; 95%CI: -0.31 to -0.04). CONCLUSIONS: Late follicular phase progesterone levels were stable during the cycles of pregnant patients irrespective of the protocols and were shown to be higher in pregnant patients in antagonist cycles when compared to agonist cycles.

The effect of serum and follicular fluid amyloid-associated protein levels on in vitro fertilization outcome in patients with polycystic ovary syndrome.

PURPOSE: In this study, we aimed to investigate serum and follicular fluid amyloid A protein levels in non-obese non-hyperandrogenic patients with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) and IVF outcome. METHODS: A total of 81 patients undergoing IVF treatment, 41 patients diagnosed as PCOS according to the Rotterdam criteria (group I) and 40 patients with the etiology of male factor infertility (group II), were included in the study. On the day of oocyte pickup, serum and follicular fluid samples were collected from all patients. RESULTS: Serum E2 level on the day of hCG (2849.93 ± 541.54 vs. 2494.28 ± 712.98) and total number of retrieved oocytes (13.73 ± 3.57 vs. 10.53 ± 4.07) were significantly higher in group I when compared to group II (p < 0.05). However, number of mature oocytes, fertilization rate, and clinical pregnancy rate did not differ (p > 0.05). No significant difference was found between two groups regarding the serum and follicular fluid amyloid A protein levels on the day of oocyte retrieval (p > 0.05).
