Background: Infertility is a global public health issue and may adversely affect life satisfaction. One of the most widely instruments used to assess life satisfaction is the Satisfaction with Life Scale (SWLS). Objective: The objective of this study was to examine the psychometric properties of the SWLS in Iranian infertile women. Materials and Methods: In this descriptive cross-sectional study, a total of 125 infertile women referring to Royan Institute in Tehran were selected by convenience sampling method. The participants were administered the SWLS, the Hospital Anxiety and Depression Scale (HADS), and a demographic questionnaire. The psychometric properties of the SWLS were examined: construct validity using confirmatory factor analysis (CFA), reliability using Cronbach's alpha and convergent validity by examining the relationship with HADS. Result: Results of the CFA indicated that a single-factor model provides a good fit to the data (χ 2 /df= 1.58; GFI= 0.975; CFI= 0.995; NFI= 0.985; RMSEA= 0.069 and SRMR= 0.027). The Cronbach's alpha coefficient for SWLS was 0.887. Significant negative correlations were found between SWLS and HADS scores for anxiety (r= -0.410) and depression (r= -0.434), indicating an acceptable convergent validity. Conclusion:The SWLS has adequate psychometric properties for assessing life satisfaction in Iranian infertile women.

Purpose To compare the number of oocytes per follicles in ovulation induction with 10,000 IU urinary hCG (uhCG) and two different doses of recombinant hCG (rhCG) in women undergoing intracytoplasmic sperm injection (ICSI) cycles. Methods This study was a prospective, randomized controlled trial which was performed on 180 primary infertile women undergoing ICSI cycles. All eligible patients underwent a standard GnRH-a long protocol. When at least two follicles reached a diameter of 18 mm, all patients were randomized to receive 10,000 IU urinary hCG or 250 μg recombinant hCG or 500 μg recombinant hCG for ovulation induction. Primary outcome measure included the number of oocytes retrieved per aspirated follicles. Secondary outcome measures were the number of oocytes retrieved, the number of mature oocytes, the number and quality of generated embryos, fertilization rate, implantation rate, chemical and clinical pregnancy rates and OHSS occurrence rate. Results The mean number of retrieved oocytes per follicles were 71.82 ± 15.09, 69.84 ± 17.44 and 77.16 ± 17.61 in 10,000 IU uhCG, 250 μg rhCG and 500 μg rhCG, respectively which was significantly higher with 500 μg rhCG than the lower dose(P=.04). Other cycles and clinical outcomes were comparable between groups. Conclusion Recombinant hCG shows equivalent efficacy to urinary hCG in terms of the number of oocytes per aspirated follicles in selected patients undergoing ICSI; however, 500 μg rhCG seems to be more advantageous than the lower dose in this indication. Larger randomized trials are needed to generalize this strategy.ClinicalTrials.gov identifier: NCT01507376.

IntroductionThe aim of the study was to compare the efficacy of half-dose, long-acting GnRH analogue (Diphereline) with Suprefact in IVF/ICSI (in vitro fertilization/intracytoplasmic sperm injection) cycles.Material and methodsIn this randomized clinical trial performed in Royan Institute, 126 infertile women who were first time candidates for IVF/ICSI were enrolled. Patients were randomly divided into two groups by using a random number table. In one group, 62 patients received a single half dose, 1.87 mg Diphereline, in mid-luteal phase. In the other group, 64 cases were treated with buserelin from the previous mid-luteal phase. P value less than 0.05 was considered significant.ResultsThe mean age of patients in the Diphereline and Suprefact groups was 27.9 ±3.6 and 29.6 ±3.5 years, respectively (p = 0.01). In the Diphereline group, the mean number of used gonadotropins was 25.6 ±12.1 ampoules, while in the second group it was 25.9 ±8.5 ampoules. Numbers of retrieved and MII oocytes were significantly higher in the Diphereline group (12.1 ±6.3 and 9.6 ±5.5) in comparison to the Suprefact group (9.4 ±6.4 and 7.2 ±5.1). Although the number of developed embryos in the Diphereline group was statistically higher than in the Suprefact group (6.1 ±3.9 vs. 4.7 ±3.4, p = 0.04) there was no significant difference in pregnancy rate (37.1%, 95% CI [26.16-49.54] vs. 37.5%, 95% CI [26.67-49.75]).ConclusionsA half-dose, long-acting GnRH agonist can be successfully used in ovarian stimulation and produces a higher number of MII oocytes and embryos. The pregnancy rates with this method are acceptable.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) has an important role in the treatment of pancreaticobiliary disorders. Goals: Considering the high prevalence and importance of postendoscopic retrograde cholangiopancreatography pancreatitis (PEP) and the controversial findings, we aimed to determine the effect of adding intravenous somatostatin to rectal indomethacin on the incidence of PEP in high-risk patients. Study: In this prospective study, 530 patients underwent ERCP during March 2018 and February 2019. Patients were randomized into 2 groups. The intervention group received a bolus injection of 250 μg somatostatin followed by an infusion of 500 μg of somatostatin for 2 hours. In both groups, 100 mg of pre-ERCP suppository indomethacin was administrated. All patients were screened for PEP symptoms and signs for 24 hours after ERCP (Iranian Registry of Clinical Trials code: IRCT20080921001264N11). Results: A total of 376 patients were finally analyzed. PEP was the most common adverse event with 50 (13.2%) episodes, including 21 (5.5%) mild, 23 (6.1%) moderate, and 6 (1.2%) severe. The rate of PEP was 15.2% in the control group and 11.4% in the intervention group (P=0.666). The incidence of post-ERCP hyperamylasemia was 21.7% in the control group and 18.2% in the intervention group (P=0.395). No death occurred. Conclusions: In this study administration of somatostatin plus indomethacin could safely reduce the rate of post-ERCP hyperamylasemia and PEP in the intervention group compared with the control group, but the differences were not significant. Further studies with larger sample sizes are required.
