Surrogacy as a good option for treatment of repeated implantation failure: a case series
Background: Repeated implantation failure (RIF) is defined as pregnancy failure after two to six times with at least ten high grade embryo transfer to uterus. A variety of causes have been anticipated for RIF, including anatomical, autoimmune, genetics, endocrine and thrombotic anomalies. Factors responsible for RIF have important implication regarding treatment however in many couples a perfect cause cannot be found. Cases: In these case series, we reported nine couples with RIF that after investigation no definitive etiology was found for RIF and empirical therapy by heparin, aspirin and or immunotherapy was not effective. In these cases we recommended transfer of embryos to surrogate uterus. Nine patients were studied and six of them developed a normal pregnancy (pregnancy rate=66.66%). Conclusion: This study showed that surrogacy is a good option for treatment of RIF
A comparative study on the results of agonist and antagonist protocols based on serum AMH levels in patients undergoing intracytoplasmic sperm injection
Background: Serum concentrations of antimullerian hormone (AMH) correlate with ovarian response during assisted reproduction treatment (ART) cycles. Objective: This retrospective study attempted to evaluate the selection of ovarian stimulation protocols based on serum AMH levels in patients and its impact on the results of ART. Materials and Methods: Based on AMH levels, the patients with tubal factor infertility were divided in three groups of normal, low and high AMH levels. Oocyte, good embryo number and pregnancy rate in each group were analyzed. Results: Using agonist and antagonist protocols, an increase in serum AMH led to higher number of oocytes and better quality embryos. At all low, normal and high AMH levels, the agonist protocol led to a more significant increase in the number of oocytes than the antagonist protocol (p<0.05). The number of high quality embryos significantly increased by the agonist protocol than antagonist protocol in women with normal AMH levels of 1.3-2.6 ng/ml (p=0.00). Moreover, the results for the number of high quality embryos at AMH �2.6 ng/ml was in favor of the antagonist protocol (p=0.00). The results showed the lowest pregnancy rate at AMH �1.3 ng/ml. At AMH �2.6 ng/ml, there was a significant increase in pregnancy rate through the antagonist protocol (p=0.04). Conclusion: Findings of this study suggested that the ART results are predictable, taking into account the AMH levels. The protocol specific to each patient can be used given the AMH level in each individual. This is because the results of each protocol depend on individual conditions. © 2016, Research and Clinical Center for Infertitlity. All rights reserved

Electrochemical sensor for determination of hydroxylamine using functionalized Fe3O4nanoparticles and graphene oxide modified screen-printed electrode
A simple strategy for determination of hydroxylamine based on Fe3O4nanoparticles function-nalized by [2-(4-((3-(trimethoxysilyl)propylthio)methyl)1-H1,2,3-triazol-1-yl)aceticacid] (FNPs) and graphene oxide (GO) modified screen-printed electrode (SPE), denoted as (Fe3O4FNPs/GO/SPE), is reported. The electrochemical behavior of hydroxylamine was investigated at Fe3O4FNPs/GO/SPE by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chro-noamperometry (CHA) techniques in phosphate buffer solution (pH 7.0). Fe3O4FNPs/GO/SPE as a novel electrochemical sensor exhibited catalytic activity toward the oxidation of hydroxylami-ne. The potential of hydroxylamine oxidation was shifted to more negative potentials, and its oxidation peak current increased on the modified electrode, also indicatingthat under these conditions,the electrochemical process is irreversible. The electrocatalytic current of hydroxyl-amine showed a good relationship in the concentration range of 0.05–700.0 μM, with a detection limit of 10.0 nM. The proposed electrode was applied for the determination of hydroxylamine in water samples, too
Subcutaneous progesterone versus vaginal progesterone for luteal-phase support in frozen-thawed embryo transfer: A cross-sectional study
Background: Luteal-phase support is a complex and controversial issue in the field of reproductive management.
Objective: To compare the safety and efficacy of low-dose subcutaneous progesterone with the vaginal progesterone for luteal-phase support in patients undergoing rozenthawed embryo transfer.
Materials and Methods: In this cross-sectional study, information related to 77 women that had frozen-thawed embryo transfer was reviewed. The patients were divided into two groups based on the route of progesterone administration used as a luteal-phase support. When the endometrial thickness reached ≥ 8 mm, in one group progesterone (Prolutex) 25 mg/ daily subcutaneous and in another group, vaginal progesterone (Cyclogest®) 400 mg twice or (Endometrin®) 100 mg thrice daily, were administrated and continued until menstruation or in case of clinical pregnancy for 8 wk after the embryo transfer when the fetal heart activity was detected by ultrasonography.
Results: The patient’s characteristics were matched and there was no significant difference. The chemical and clinical pregnancy rate was higher in the vaginal progesterone group compared to the prolutex group, but statistically unnoticeable, (40% vs. 29.6%, p = 0.367) and (28% vs. 22.2%, p = 0.581), respectively. C
Conclusion: The findings of this study demonstrate that the new subcutaneous progesterone can be a good alternative for intramuscular progesterone in women that dislike and do not accept vaginal formulations as luteal-phase support in assisted reproductive technology.

The Effect of Estradiol and Progesterone on Toll Like Receptor Gene Expression in A Human Fallopian Tube Epithelial Cell Line
OBJECTIVE: Toll like receptors (TLRs) are one of the main components of the innate im- mune system. It has been reported that expression of these receptors are altered in the female reproductive tract (FRT) during menstrual cycle. Here we used a fallopian tube epithelial cell line (OE-E6/E7) to evaluate the effect of two sex hormones in modulating TLR expression. MATERIALS AND METHODS: In this experimental study, initially TLR gene expression in OE- E6/E7 cells was evaluated and compared with that of fallopian tube tissue using quanti- tative real time-polymerase chain reaction (qRT-PCR) and immunostaining. Thereafter, OE-E6/E7 cells were cultured with different concentrations of estradiol and progesterone, and combination of both. qRT-PCR was performed to reveal any changes in expression of TLR genes as a result of hormonal treatment. RESULTS: TLR1-10 genes were expressed in human fallopian tube tissue. TLR1-6 genes and their respective proteins were expressed in the OE-E6/E7 cell line. Although estradiol and progesterone separately had no significant effect on TLR expression, their combined treatment altered the expression of TLRs in this cell line. Also, the pattern of TLR expres- sion in preovulation (P), mensturation (M) and window of implantation (W) were the same for all TLRs with no significant differences between P, M and W groups. CONCLUSION: These data show the significant involvement of the combination of es- tradiol and progesterone in modulation of TLR gene expression in this human fal- lopian tube cell line. Further experiments may reveal the regulatory mechanism and signalling pathway behind the effect of sex hormones in modulating TLRs in the hu- man FRT
Aspiration versus retention ultrasound-guided ethanol sclerotherapy for treating endometrioma: A retrospective cross-sectional study
Background: Endometrioma is a common high-recurrence gynecological disease that affects infertility. Surgical resection using laparotomy or laparoscopy is applied as a standard treatment. Moreover, sclerotherapy is reported to be effective as a noninvasive method for treating endometrioma.
Objective: To evaluate whether the ethanol retention or aspiration after sclerotherapy improve pregnancy outcome in infertile women with endometrioma.
Materials and Methods: In a retrospective study, hospital records of 43 women with recurrent or bilateral endometrioma who had been undergone transvaginal ultrasound sclerotherapy were reviewed. They were selected to receive either ethanol for 10 min, ethanol injection, irrigation, and then aspiration or total retention without aspiration based on the surgeon’s decision. The participants were followed-up for 3, 6 and 12 months for natural or artificial conception as well as for cyst recurrence.
Results: Chemical pregnancy was positive in 52% of the women in the aspiration group and 53.8% in the retention group. Ongoing pregnancy (44% vs 46.2%, p = 0.584) and live birth (40% vs 46.2%, p = 0.490) were reported marginally higher in the retention group compared with the aspiration group, and the differences were not statistically significant. Moreover, the recurrence rate were found to be 48.1% and 37.5% in the aspiration and retention groups, respectively (p = 0.542). The cysts size in the retention group was significantly correlated to the recurrence rate.
Conclusion: Both the aspiration and left in situ of ethanol 95% sclerotherapy have the similar impact on the treatment of ovarian endometrioma regarding pregnancy and recurrence rate. However, larger randomized studies with strict inclusion criteria are needed.

Variable localization of Toll-like receptors in human fallopian tube epithelial cells
Objective: To determine the localization, expression, and function of Toll-like receptors (TLRs) in fallopian tube epithelial cells. Methods: The localization of TLRs in fallopian tube epithelial cells was investigated by immunostaining. Surprisingly, the intensity of staining was not equal in the secretory and ciliated cells. After primary cell culture of fallopian tube epithelial cells, ring cloning was used to isolate colonies of ciliated epithelial cells, distinct from non-ciliated epithelial cells. The expression of TLRs 1-10 was examined by quantitative real-time polymerase chain reaction, and protein localization was confirmed by immunostaining. The function of the TLRs was determined by interleukin (IL)-6 and IL-8 production in response to TLR2, TLR3, TLR5, TLR7, and TLR9 ligands. Results: Fallopian tube epithelial cells expressed TLRs 1-10 in a cell-type-specific manner. Exposing fallopian tube epithelial cells to TLR2, TLR3, TLR5, TLR7, and TLR9 agonists induced the secretion of proinflammatory cytokines such as IL-6 and IL-8. Conclusion: Our findings suggest that TLR expression in the fallopian tubes is cell-type-specific. According to our results, ciliated cells may play more effective role than non-ciliated cells in the innate immune defense of the fallopian tubes, and in interactions with gametes and embryos
Comparing the effects of nursing versus peer-based education methods on the preoperative anxiety in infertile women: An RCT
Background: Preoperative anxiety is a common event in patients expecting surgery. Education can play an important role in reducing the negative effects of anxiety on the response to treatment. Therefore, identifying the appropriate method is important.
Objective: The aim of this study was comparing the effects of nursing versus peer-based education on the preoperative anxiety in infertile women.
Materials and Methods: In this clinical trial, 198 eligible infertile women were randomized into three groups (n= 66/each): the nurse-educated, peer-educated, and the controls. The Spielberger State-Trait Anxiety Inventory was filled out by all participants for measuring the patient anxiety at the time of hospital admission and prior to surgery. Participants in the nurse-educated and peer-educated groups received a group education program by a nurse or peer, respectively, after the initial completion of the Spielberger State-Trait Anxiety Inventory.
Results: The mean score anxiety was 44.47, 46.92, and 42.60 at the time of hospital admission and 39.38, 41.06, and 43.42 prior to surgery in nurse-educated, peer-educated, and the control groups, respectively. There was a significant difference in the mean score of anxiety in each group before and after the intervention (p < 0.0001). However, the difference between the groups was not significant.
Conclusion: Our findings demonstrate that nursing and peer education programs both reduce the preoperative anxiety. Hence, optimal use of the peer's potential regarding the compensation for staff shortage for preoperative education as well as investigating the effect of individual education is suggested for further studies.

Characteristics of the human endometrial regeneration cells as a potential source for future stem cell-based therapies: A lab resources study
Background: Human endometrium with consecutive regeneration capability undergoes monthly hormonal changes for probable implantation, which confirms the presence of the cells in the basalis layer known as stem cell.
Objective: Previously, we reported the isolation and culture of the mesenchymal-like cells from human endometrium. In this study, we evaluated the biological and stemness characteristics of these cells.
Materials and Methods: The characterization of Yazd human endometrialderived mesenchymal stem/stromal cells (YhEnMSCs) was assessed using immunofluorescence (IF) staining for CD105, VIMENTIN, and FIBRONECTIN as markers and RT-PCR for CD166, CD10, CD105, VIMENTIN, FIBRONECTIN, MHCI, CD14, and MHCII genes. Flow cytometry (FACS) was performed for CD44, CD73, CD90, and CD105 markers. Moreover, the differentiation capacity of the YhEnMSCs to the osteoblast and adipocytes was confirmed by Alizarin Red and Oil Red staining.
Results: YhEnMSCs expressed CD105, VIMENTIN, FIBRONECTIN, CD44, CD73, and CD90 markers and CD166, CD10, CD105, VIMENTIN, FIBRONECTIN, and MHCI, but, did not express CD14, MHCII.
Conclusion: Our data confirm previous reports by other groups indicating the application of endometrial cells as an available source of MSCs with self-renewal and differentiation capacity. Accordingly, YhEnMSCs can be used as a suitable source for cell-based therapies.
