RESUMO

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.

RESUMO

BACKGROUND AND AIM: Maternal smoking is associated with an increased risk of obstetric and neonatal complications during pregnancy. We aimed to investigate the effects of active and passive smoking on fetal-maternal blood flow and fetal complications in mid-trimester pregnant women. METHODS: This prospective study was conducted at Zekai Tahir Burak Women's Research and Training Hospital and included women who were 20 to 22 weeks old, with no fetal anomalies, and with a singleton pregnancy. The data used in the analysis were obtained from a total of 168 pregnant women (50 smokers, 50 passive smokers, and 68 non-smokers). Starting from their 20th week of pregnancy, the women were examined at least once in each trimester. Fetal and maternal pregnancy results were evaluated. Fetal biometry, umbilical, and uterine artery Doppler ultrasonography were performed. To evaluate the flow in these veins, the pulsatility index, resistance index, and systole/diastole (S/D) ratio were performed. RESULTS: The mean age of study patients was 25.06 ± 4.36 years and the mean gestational week was 20.03 ± 0.6 weeks. In terms of the umbilical artery pulsatility index (UMBAPI), umbilical artery systolic/diastolic ratio (UMBAS/D),uterine artery resistance index (UARI), uterine artery pulsatility index (UAPI), and uterine artery systolic/diastolic ratio (UAS/D) levels, the mean value of the smoker group was significantly higher compared to the non-smoker group (p<0.001, p=0.043, p=0.021, p=0.020, and p=0.037, respectively). The birth weight of the fetus was significantly lower in the active and passive smoker groups than in the non-smoker group (p=0.009 and p=0.006, respectively). The number of patients diagnosed with intrauterine growth restriction (IUGR) and oligohydramnios were significantly higher in the smoker group than in the passive smoker and non-smoker groups (p=0.003 and p<0.001, respectively). The risk of low birth weight (OR, (95% CI): 3.38 (2.05 - 5.57); p=0.024), oligohydramnios (OR (95% CI): 13.44 (5.22 - 34.57); p=0.001), IUGR (OR (95% CI): 9.33 (4.50 - 19.33); p=0.001), and preterm birth (OR (95% CI): 4.56 (1.25 - 17.32); p=0.001) increased significantly in the active and passive cigarette exposure groups, compared to the non-smokers. CONCLUSION: During pregnancy, both smoking and passive exposure to cigarette smoke adversely affect the fetus and the newborn. Uterine and umbilical artery Doppler measurements in pregnant women who smoke are significantly higher than the pregnant women who do not smoke.

RESUMO

OBJECTIVE: To compare the advanced glycation end products (AGEs) levels in follicular fluid according to the different ovarian responses of women who underwent controlled ovarian stimulation due to unexplained infertility and to examine the relationship between these levels and pregnancy outcomes. METHODS: Sixty-three women who underwent fresh IVF/ICSI cycles with GNRH antagonist protocol were divided into 3 groups according to the number of retrieved oocytes as suboptimal (4-9 oocytes), optimal (10-15 oocytes) and high (>15 oocytes) responders. AGEs levels in follicular fluid were measured by ELISA method. RESULTS: AGEs levels were 6.81 ± 2.20 µg/ml, 5.30 ± 2.01 and 6.44 ± 1.43 µg/ml in suboptimal, optimal and high response group, respectively. AGEs level was significantly higher in suboptimal response group than in optimal response group. The cutoff level of 6.19 µg/ml had a sensitivity of 59.3% and a specificity of 66.7% in distinguishing the suboptimal response group from the optimal response group. However, there were no statistically significant difference between AGEs levels and clinical pregnancy and live birth rates. CONCLUSION: Increased AGEs level in follicular fluid may be associated with decreased ovarian response during controlled ovarian stimulation in unexplained infertility case, however, it does not provide information about pregnancy outcomes.

RESUMO

OBJECTIVE: This study aims at assessing the effectiveness of various treatment protocols with the help of some parameters in caesarean scar pregnancies. METHODS: A total of 26 patients were assessed in the study. The patients were divided into 4 groups. Group 1 consisted of those who had a wedge resection (n = 7), group 2 those who had a suction curettage (n = 10), group 3 those who had a systemic methotrexate (MTX) (n = 5) and group 4 those who had a systemic + local MTX (n = 4). The ßHcg half-lives, haemoglobin levels at the time of admittance and discharge, and hospital stays of the groups were compared. RESULTS: The difference between group 1 and group 4 was found significant (p = 0.002) with respect to days of hospital stay. There was no statistically significant difference between the groups with respect to ßHcg half-lives and haemoglobin values. CONCLUSION: The results of our study showed that there were no significant differences between treatment outcomes when appropriate protocols were employed. Therefore, the important point in CSPs is to assess correctly the type of CSP, the myometrial thickness and the patient's hemodynamic condition and select the most appropriate protocol accordingly rather than trying to establish a single standard treatment protocol.

RESUMO

OBJECTIVE: The aim of the study was to compare the outcome of assisted reproductive treatment fresh cycles, in patients with low prognosis which were stratified according to the POSEIDON (Patient-Oriented Strategies Encompassing IndividualizeD Oocyte Number) criteria. MATERIALS AND METHODS: This retrospective cohort study including all fresh assisted reproductive treatment cycles age < 44 years, between January and December 2017 was carried out from patient records of Zekai Tahir Burak Women Health Care Education and Research Hospital IVF Clinic. A total of 525 IVF cycles were analyzed and 276 patients fulfilling the POSEIDON criteria for poor ovarian response (POR) were included in the study. RESULTS: Implantation rate, clinical pregnancy rate, and early miscarriage rate were similar in four POSEIDON groups. Live birth rate (LBR) is statistically higher in unexpected POR groups and also significantly higher in POSEIDON group 3 when compared with POSEIDON group 4. CONCLUSION: LBRs are not homogenous in low prognosis patients fulfilling POSEIDON criteria and it seems unexpected POR groups have the most favorable pregnancy outcomes. In unexpected POR groups, age was not a determinant factor in IVF success but in the expected group, age is the most powerful determinant factor.

RESUMO

In this study, our aim was to determine which factor is more correlated with the number of oocytes retrieved in patients with endometrioma compared with controls undergoing in vitro fertilisation-intracytoplasmic sperm injection (IVF-ICSI) cycles: antral follicle count (AFC) or anti-Müllerian hormone (AMH). A total of 60 women with endometrioma and a control population of 60 women without endometrioma in the same period were randomly selected underwent the injection IVF-ICSI treatment. No significant differences were found between the groups in terms of age (28.78 ± 3.49 vs. 29.52 ± 2.47, p = .187), body mass index (23.62 ± 2.05 vs. 23.91 ± 2.11, p = .449), duration of infertility [(3 (2-4) vs. 3 (2-3), p = .139)], AMH level (1.52 ± 0.51 vs. 1.32 ± 0.92, p = .133), duration of stimulation [(9 (9-10) vs. 10 (9-10), p = .135)], total gonadotropin dose [(2750 (2262.5-3337.5) vs. 2770 (2680-3562.5), p = .125)], endometrial thickness [(10 (10-11) vs. 10 (9-11), p = .463)], fertilisation rates (67.20 ± 18.04 vs. 62.28 ± 17.13, p = .123), grade I embryo (43.3% vs. 30%, p = .185), clinical pregnancy rates (40% vs. 26.7%, p = .123), and the perinatal outcomes between the groups. The AFC was higher in the controls than in those with endometrioma (9.20 ± 1.80 vs. 6.32 ± 2.04, p < .001). The number of oocytes retrieved was also higher in the controls than in those with endometrioma [(7 (6-8) vs. 4 (4-5.75), p < .001)]. We found that women with endometrioma had a significantly lower number of oocytes retrieved than the controls despite the same AMH levels in both groups. AFC is a better marker of ovarian response than AMH in women with endometrioma undergoing IVF-ICSI. Impact statement What is already known on this subject? Utilising the ovarian reserve is important in the success of ovarian stimulation and in evaluating the success of assisted reproductive technologies. The anti-Müllerian hormone (AMH) level and the antral follicle count (AFC) are widely used in the prediction of ovarian functional reserve and response. However, no perfect marker exists in the evaluation of ovarian reserve and ovarian response. What do the results of this study add? Our study demonstrated that women with endometrioma have a significantly lower number of oocytes retrieved than the controls, despite the same AMH levels in both groups; which strongly suggests that AFC is a better reflection of ovarian response than AMH in women with endometrioma undergoing an in vitro fertilisation-intracytoplasmic sperm injection (IVF-ICSI). What are the implications of these findings for clinical practice and/or further research? This important issue has been reviewed and discussed for years, however, the conclusions are still controversial. Additional research is needed to understand which ovarian reserve test could better predict ovarian response outcome?

RESUMO

AIM: Controlled ovarian hyperstimulation results in elevated levels of estrogen during in vitro fertilization (IVF). Although serum ovarian steroid hormones were found to influence central nervous system and anesthetic requirements, the relationship between propofol requirements and serum estrogen concentration in women undergoing oocyte retrieval has not been studied. The aim of this study was to determine the relationship between serum estrogen and progesterone concentrations and the required propofol dose for loss of consciousness (LOC). METHODS: Ninety patients undergoing oocyte retrieval for IVF were enrolled. Anesthesia was induced by administration of 200 mL/h propofol (1%) infusion to reach LOC. Anesthesia was maintained with a propofol infusion guided by entropy. The correlation between estrogen, progesterone levels and propofol dose at the time of LOC was analyzed. Emergence time from anesthesia and total propofol consumption were recorded. RESULTS: The mean serum estradiol concentration was 1825 ±1135 pg/mL. There was a significant positive correlation between serum estradiol and propofol dose required for LOC (Pearson's correlation r = 0.28, P = 0.008). Progesterone had no significant correlation with total propofol dose at the time of LOC. Patients with high estradiol levels (higher than the median value) had similar propofol requirement for LOC, total propofol consumption and emergence time with patients who had low (below the median value) levels. CONCLUSION: Although increased estrogen levels create a positive correlation with propofol dose for LOC, estrogen does not seem to be the only factor for anesthetic requirement of patients undergoing controlled ovarian hyperstimulation.

RESUMO

Abstract Sirtuin 1 has an important role in cellular processes, including apoptosis and cellular stress. The purpose of this study was to assess serum sirtuin 1 levels in women with recurrent implantation failure (RIF). In this cross-sectional study, we included 28 women with RIF, 29 healthy women who had conceived by in vitro fertilization (IVF), and 30 women with a 1-cycle failure of IVF as controls. Human serum nicotinamide adenine dinucleotide (NAD)-dependent deacetylase sirtuin-1 (SIRT1/SIRT2L1) levels were detected using a commercial colorimetric kit. Recurrent implantation failure patients have higher sirtuin 1 levels than non-pregnant women and healthy pregnant women, but this difference did not reach statistical significance due to the low number of patients in our study. These higher sirtuin 1 levels may result from the inflammation imbalance of RIF patients. The only statistically significant correlation found was between age and sirtuin (r = 0.277, p = 0.009).


Resumo A sirtuína 1 tem importante função nos processos celulares, incluindo a apoptose e o estresse celular.

Neste estudo cruzado, incluímos 28 mulheres com FRI, 29 mulheres saudáveis que deram à luz por fertilização in vitro (FIV) bem-sucedida, e 30 mulheres com 1 ciclo de FIV malsucedido como controle. Os níveis de sirtuína 1 em soro humano de desacetilase dependente de dinucleotídeo de nicotinamida adenina (DNA) (SIRT1/SIRT2L1) foram detectados usando um kit colorimétrico comercial. Pacientes com FRI tiveram níveis de sirtuína 1 superiores às pacientes grávidas e aos controles, mas esta diferença não atingiu significância estatística devido ao baixo número de pacientes envolvidos. Estes níveis mais altos de sirtuína 1 podem ser resultado da inflamação desigual em pacientes com FRI. A única correlação estatisticamente significante encontrada foi entre idade e sirtuína (r = 0,277, p = 0,009).

RESUMO

OBJECTIVES: The purpose of this study was to determined the predictive value of maternal serum alpha-fetoprotein (MSAFP) as a marker for adverse pregnancy outcomes. MATERIAL AND METHODS: This study was carried out at Dr. Zekai Tahir Burak Women's Health Education and Research Hospital between 2009 and 2010. This study included a total of 1,177 pregnant women, including 170 in the study group and 1,007 in the control group. Pregnancy outcomes and characteristics were analyzed with regard to the MSAFP value. RESULTS: Gestational week, birth weight and APGAR scores were significantly lower in the elevated MSAFP group (p < 0.001). Adverse pregnancy outcomes, such as preterm delivery, preterm premature rupture of membranes (PPROM), oligohydramnios and intrauterine growth restriction (IUGR) rates were increased in the elevated MSAFP group. CONCLUSIONS: Although ultrasound outweighs as a screening method for neural tube defects and non-invasive prenatal testing outweighs for aneuploidy screening MSAFP level in the second trimester is still an important predictor for poor maternal/fetal outcomes.

RESUMO

BACKGROUND: Estrogen is known to affect both mammographic breast density and bone mineral density (BMD), but there are inconsistent results about the association of these density measurements in postmenopausal women. Furthermore, there are scarce data on the relationship between breast density and BMD in never users of postmenopausal hormone therapy. AIM: In this study, we examined the relationship between mammographic breast density and BMD in postmenopausal women who were never hormone replacement therapy users. METHODS: A total of 293 postmenopausal women were enrolled in this cross-sectional study. Mammograms and BMD measurements for screening purposes were obtained. Assessment of mammographic breast density was performed by using breast imaging reporting and data system classification. The BMD was measured using dual-energy X-ray absorptiometry of the lumbar spine and femoral neck. RESULTS: Grade 1 breast density was observed in 64 women (21.8 %), grade 2 in 113 women (38.6 %) and grades 3 and 4 in 116 (39.6 %) women. Breast density decreased with increasing age and body mass index (BMI). Meanwhile, no significant differences were detected in BMD measures of the hip (p = 0.14) and lumbar spine (p = 0.29) among the breast density categories. After adjusting for age and BMI, the differences in the mean BMD at the hip and lumbar spine across the breast density categories remained insignificant (p = 0.26 and 0.11, respectively). CONCLUSION: There is no evidence of a relationship between mammographic breast density and BMD in postmenopausal women who had never used hormone replacement therapy.

RESUMO

BACKGROUND: We aimed to evaluate the efficacy and safety of dinoprostone for cervical ripening and labor induction in patients with term oligohydramnios and Bishop score ≤ 5. METHODS: This was a prospective case-control study, which included 104 consecutive women with a Bishop score≤5. Participants were divided into two groups. Women with term isolated oligohydramnios and Bishop score≤5 underwent induction of labor with a vaginal insert containing 10-mg timed-release dinoprostone (prostaglandin E2; Group A, n=40). The control group, Group B, consisted of 64 cases of pregnancy with normal amniotic fluid volume (amniotic fluid index≥5 cm) and Bishop score≤5, and was matched for patient's age and parity. The primary outcome was time from induction to delivery; the secondary outcomes were the caesarean section (CS) rate, uterine hyperstimulation, rate of failed induction, and neonatal complications. RESULTS: The mean time interval from induction to delivery was not different between the two groups (p=0.849), but there was a statistically significant difference between the groups in terms of the CS rate (p=0.005). There were no differences between the groups in neonatal outcome or perinatal morbidity or mortality. CONCLUSION: Dinoprostone appears to be a safe alternative for induction of labor in pregnancies with oligohydramnios. Induction of labor with dinoprostone in term pregnancies with isolated oligohydramnios is associated with increased rate of CS but there is no higher risk of perinatal complications.

RESUMO

OBJECTIVE: To investigate the effect of luteal phase support with vaginal progesterone on pregnancy rates of the gonadotropin-stimulated intrauterine insemination (IUI) cycles in patients with unexplained infertility with regard tofollicular growth. STUDY DESIGN: A total of 149 patients with unexplained infertility who underwent 166 recombinant follicle stimulated hormone--stimulated IUI cycles were prospectively randomized into 2 groups for luteal phase support. The study group (n = 71) received vaginal progesterone gel supplementation, and the control group (n = 78) received no drug for luteal support. The clinical pregnancy rates and live birth rates per cycle and per patient were compared between the groups. RESULTS: The differences between the groups with regard to clinical pregnancy rates and live birth rates per patient or per cycle were not different among all patients. In cycles with > 1 dominant follicle (multifollicular response), the clinical pregnancy rate per patient was significantly higher in the supported cycles as compared with the unsupported cycles (28.2% vs. 11.4%, respectively, p = 0.04). Reproductive outcomes in cycles with a single dominant follicle (monofollicular response) were not different between supported and unsupported cycles. CONCLUSION: Luteal phase support with vaginal progesterone affects the success of gonadotropin-stimulated IUI cycles with multifollicular response but not with monofollicular response.

RESUMO

BACKGROUND: Reactive oxygen species (ROS) are produced in many metabolic and physiologic processes. Antioxidative mechanisms remove these harmful species. Our aim was to assess whether serum total antioxidant capacity and total oxidant status altered during first trimester pregnancies with vaginal bleeding. MATERIALS AND METHODS: In this cross-sectional study, A group of pregnant women at less than 10 weeks of gestation with vaginal bleeding (n=25) and a control group of healthy pregnancies with similar characteristics (n=25) were included. All of the patients in the two groups were matched for age, gestational age and body mass index. Serum total antioxidant capacity and total oxidant status levels were determined using a Hitachi 912 analyzer and compared between the two groups. RESULTS: Characteristics, including maternal age, parity, and gestational age were similar between the two groups. Serum total antioxidant capacity levels were significantly lower in the women with vaginal bleeding than in control women (1.16 ± 0.20 vs. 1.77 ± 0.08 mmol Trolox Equiv./L; p=0.001), whereas higher total oxidant status measurements were found in women with vaginal bleeding compared to the control group (4.01 ± 0.20 vs. 2.57 ± 0.65 µmol H2O2 Equiv./L; p=0.001). CONCLUSION: Increased total oxidant status might be involved in the pathophysiology of vaginal bleeding during early first trimester pregnancies.

RESUMO

PURPOSE: To evaluate the influence of ultrasound guidance during intrauterine insemination (IUI) on pregnancy rates (PRs). The impacts of two different groups of providers were also investigated. METHODS: Study population consisted of 387 gonadotropin stimulated IUI cycles performed for unexplained infertility. The patients were randomized into two groups as ultrasound-guided IUI (n = 180) and classical IUI (n = 207). Pregnancy rates were compared. Two groups were further analyzed based on the experience of the provider (senior versus junior subgroups) who performed IUI. RESULTS: Pregnancy rates were higher in the ultrasound-guided IUI group (17.2%) compared to the classical IUI (10.1 %) (p = 0.042). In further analysis based on the experience of the provider; in the classical IUI group, PRs were similar for both subgroups, however, in the ultrasound-guided group it was higher when IUI was performed by a senior physician (21.7 versus 9.2%, p = 0.033). Logistic regression revealed that the experience of the provider was the independent variable for improved PRs. CONCLUSIONS: Ultrasound guidance improves PRs only when a senior provider performs the IUI procedure. It seems that the experience of the provider physician is one of the determinants of IUI success.

RESUMO

PURPOSE: We aimed to find out the effect of abortus imminens (AI) on obstetric outcomes of pregnancies which continued beyond the 24th week of gestation. METHODS: In this prospective study, 309 patients with AI were divided into high-risk group (with a risk factor for spontaneous abortus) (n = 92) and low-risk group (without a risk factor) (n = 217). The control group (n = 308) was chosen randomly. RESULTS: In AI group, preterm delivery, preterm premature rupture of membranes (PPROM), cesarean section (C/S) delivery, postpartum uterine atony and need of a neonatal intensive care unit (NICU) rates were significantly higher than control group. Gestational diabetes mellitus, PPROM, still birth, low APGAR scores were seen more frequently in the high-risk patients than in the control group. Furthermore in the high-risk group, preterm delivery, malpresentation, C/S delivery and need of NICU were increased much more than in the low-risk group. Gestational hypertension/preeclampsia, oligo/polyhydramniosis, intrauterine growth retardation, placenta previa, abruption of placenta, chorioamnionitis, congenital abnormalities, delivery induction, cephalopelvic disproportion, fetal distress and manual removal of placenta were not different among the groups. CONCLUSIONS: Patients with AI history, especially with high-risk factors can have adverse obstetric and neonatal results. So their antenatal follow-up has to be done cautiously for the early signs and symptoms of these complications.

RESUMO

We evaluated the effect of mandatory single embryo transfer (SET) on live birth rates and pregnancy outcomes in Turkey. A retrospective study was conducted in Zekai Tahir Burak Women's Health Education and Research Hospital. Four hundred and four patients undergoing intracytoplasmic sperm injection (ICSI) cycles were included in the study. In Turkey, the number of embryos to be transferred in an assisted cycle was limited to three under normal circumstances until 6 March 2010. After that, new legislation was introduced to promote the application of SET. Outcomes were compared in periods of 1 year before and after the new law. We compared pregnancy outcomes of all assisted reproductive cycles in SET cycles (group 1: n = 281) with double embryo transfer (DET) cycles (group 2: n = 123). There were significant differences in oocyte number, multiple pregnancy, gestational age, birth weight and perinatal fetal morbidity between the groups (p = 0.023, 0.001, 0.001, 0.001, 0.001, respectively). But there were no differences in age, baseline FSH, infertility period, stimulation protocol, stimulation day, gonadotrophin dose, clinical pregnancy rate, abortion rate, live birth rate and cesarean rate (p > 0.05). These results suggest that under the new legislation multiple pregnancy rates and perinatal complications are significantly reduced without causing a significant decline in the pregnancy rates.

RESUMO

Objectives. Hospital fear and avoidance of the routine hospital obstetrical interventions cause some women with low-risk pregnancies to spend most of the active labor period at home, and subsequently they present to the hospital for delivery. Our aim was to analyze the maternal and neonatal outcomes of pregnancies with a planned hospital birth, yet spending the first stage of labor at home without a health provider and completing the delivery in the hospital setting. Methods. We retrospectively compared 238 pregnancies having home labor plus hospital delivery (study group) with 476 pregnancies that had spent the whole labor in the hospital setting, considering various maternal and neonatal outcomes. Results. Cesarean and episiotomy rates were lower (P < 0.0001 and P < 0.001, resp.), but neonatal intensive care unit admissions of the infants were more prevalent (P < 0.01) in the study group. Other maternal and neonatal outcomes including neonatal mortality were comparable. Conclusion. Although our preliminary data generally do support the safety of home active labor plus hospital delivery for low-risk pregnancies, the clinical implications of current data warrant further prospective trials.

RESUMO

BACKGROUND: In recent years, it has become evident that ovarian stimulation, although a central component of in vitro fertilization (IVF), may itself has detrimental effects on oogenesis, embryo quality, endometrial receptivity, and perhaps also perinatal outcomes. OBJECTIVE: To evaluate the effect of higher gonadotrophin dose on clinical pregnancy rate in normo-responder ICSI cycles with long protocol. METHODS: A retrospective study was planned in the Department of Reproductive Endocrinology of Zekai Tahir Burak Women's Health Education and Research Hospital. 362 normo-responders undergoing ICSI cycles with long protocol were included in the study. Group 1 (n = 260): Total gonadotrophin dose <2198 IU and Group 2 (n = 102): Total gonadotrophin dose >2198 IU. Laboratory IVF outcome, clinical pregnancy rate were evaluated. RESULT(S): There was no statistically significant difference between peak estradiol levels, endometrial thickness, fertilization rates among the Group 1 versus Group 2 (p > 0.05). But there was a statistically significant difference in age, baseline FSH, oocyte number, 2PN, and clinical pregnancy among the Group 1 versus Group 2. Clinical pregnancy rate were significantly higher in Group 1 compared with Group 2 (p < 0.001). Lower gonadotrophin dose, 2PN was an independent positive predictor of clinical pregnancy (OR 2.65 for gonadotrophin dose, OR 1.1 for 2PN) CONCLUSION(S): Higher total gonadotrophin dose adversely affect clinical pregnancy in normo-responder patients undergoing ICSI cycles with long protocol.
