Abstract

Background: Despite major advances in assisted reproductive techniques, the implantation rates remain relatively low. Some studies have demonstrated that intrauterine infusion of granulocyte colony stimulating factor (G-CSF) improves implantation in infertile women.
Objective: To assess the G-CSF effects on IVF outcomes in women with normal endometrial thickness.
Materials and methods : In this randomized controlled clinical trial, 100 infertile women with normal endometrial thickness who were candidate for IVF were evaluated in two groups. Exclusion criteria were positive history of repeated implantation failure (RIF), endocrine disorders, severe endometriosis, congenital or acquired uterine anomaly and contraindication for G-CSF (renal disease, sickle cell disease, or malignancy). In G-CSF group (n=50), 300 µg trans cervical intrauterine of G-CSF was administered at the oocyte retrieval day. Controls (n=50) were treated with standard protocol. Chemical, clinical and ongoing pregnancy rates, implantation rate, and miscarriage rate were compared between groups.
Results: Number of total and mature oocytes (MII), two pronuclei (2PN), total embryos, transferred embryos, quality of transferred embryos, and fertilization rate did not differ significantly between two groups. So there were no significant differences between groups in chemical, clinical and ongoing pregnancy rate, implantation rate, and miscarriage rate
Conclusion: our result showed in normal IVF patients with normal endometrial thickness, the intrauterine infusion of G-CSF did not improve pregnancy outcomes.

Abstract

Background: Human leukocyte antigen-G (HLA-G) is a non-classical class I molecule highly expressed by extravillous cytotrophoblast cells. Due to a single base pair deletion, its function can be compensated by other isoforms. Investigating the frequency of null allele in Recurrent Miscarriage (RM) subjects could be useful in understanding the relationship between frequency of this allele and RM in a given population. 
Objective: This study aimed to determine the frequency of HLA-G*0105N null allele and its potential association with down-regulation of HLA-G in subjects with RM. 
Materials and Methods: Western blotting was used to assess the level of HLA-G protein expression. For investigating the frequency of HLA-G*0105N null allele in RM subjects, PCR-RFLP method was used. Exon 3 of HLA-G gene was amplified by polymerase chain reaction (PCR). Subsequently, PpuM-1 enzyme was employed to digest the PCR products and fragments were analyzed using gel electrophoresis. 
Results: Digestion using restriction enzyme showed the presence of heterozygous HLA-G*0105N null allele in 10% of the test population. Western blotting results confirmed the decrease in expression of HLA-G in the placental tissue of subjects with RM compared to subjects who could give normal birth. 
Conclusion: The frequency of heterozygous HLA-G*0105N null allele was high to some extent in subjects with RM. The mutation rate in subjects suggested that there is a significant association between RM and frequency of mutations in this allele.

Abstract

Background: Implantation failure is one of the most important factors limiting success in IVF treatment. The majority of trials have demonstrated favorable effect of endometrial injury on implantation success rate especially in women with recurrent implantation failure, while some studies failed to detect any benefit. 
Objective: The purpose of our trial was to explore whether endometrial injury in luteal phase prior to frozen-thawed embryo transfer cycles would improve pregnancy outcomes? 
Materials and Methods: We conducted a prospective controlled trial of 93 consecutive subjects at a research and clinical center for infertility. All women were undergone frozen-thawed embryo transfer (FTE) cycles. Women in the experimental group underwent endometrial biopsy with a Pipelle catheter in luteal phase proceeding FET cycle. Primary outcomes were implantation and clinical pregnancy rates and secondary outcomes were chemical, ongoing and multiple pregnancy and miscarriage rates. 
Results: 45 subjects who underwent endometrial injury (EI) were compared with 48 control group which did not include any uterine manipulation. There were no significant differences in baseline and cycle characteristics between two groups. The difference in implantation rate was trend to statistically significance, 11.8% in EI group vs. 20.5% in control group (p=0.091). The chemical, clinical and ongoing pregnancy rates were lower in EI group compared with control group but not statistically significant. The multiple pregnancy rate and miscarriage rate also were lower in EI group compared with control group. 
Conclusion: Based on results of this study, local injury to endometrium in luteal phase prior to FET cycle had a negative impact on implantation and clinical pregnancy rates.

Abstract

Background: Management of poor-responding patients is still major challenge inassisted reproductive techniques (ART). Delayed-start GnRH antagonist protocol isrecommended to these patients, but little is known in this regards.
Objective: The goal of this study was assessment of delayed-start GnRH antagonistprotocol in poor responders, and in vitro fertilization (IVF) outcomes.
Materials and Methods: This randomized clinical trial included sixty infertilewomen with Bologna criteria for ovarian poor responders who were candidate forIVF. In case group (n=30), delayed-start GnRH antagonist protocol administeredestrogen priming followed by early follicular-phase GnRH antagonist treatment for7 days before ovarian stimulation with gonadotropin. Control group (n=30) treatedwith estrogen priming antagonist protocol. Finally, endometrial thickness, the ratesof oocytes maturation, , embryo formation, and pregnancy were compared betweentwo groups.
Results: Rates of implantation, chemical, clinical, and ongoing pregnancy indelayed-start cycles were higher although was not statistically significant.Endometrial thickness was significantly higher in case group. There were nostatistically significant differences in the rates of oocyte maturation, embryoformation, and IVF outcomes between two groups.
Conclusion: Delayed-start GnRH antagonist protocol can be a new hope method totreatment poor ovarian responders.

Abstract

Background: Ovarian superovulation and increased follicle-stimulating hormone concentration for infertility treatment may be the risk factors of developed granulosa-cell tumor. The aim of this report is to introduce a case of granulosa-cell tumor which was discovered after ovarian stimulation.
Case: A 31-yr-old woman with clinical presentation of massive abdominal distention was referred to the gynecology and oncology department of an academic hospital, Mashhad University of Medical Sciences in Aug 2017. She had the history of secondary infertility and was undergoing In Vitro Fertilization protocol and ovarian stimulation, but, the cycle was canceled. The patient suffered from gradual abdominal distention one month after the end of IVF procedure despite pregnancy failure. 2-3 months after management of the ovarian hyperstimulation syndrome, investigation revealed large ovarian mass and increased tumor marker inhibin. Exploratory laparotomy was performed and revealed stage III ovarian cancer. The final pathology report indicated juvenile granulosa cell tumor. So, optimal surgical staging and cytoreductive surgery without fertility preserving were perfumed. Chemotherapy was recommended due to the advanced stage of ovarian cancer. Unfortunately, she experienced metastatic diseases in pelvic and abdomen in less than six months; and currently is receiving the second and third line chemotherapy.
Conclusion: Persistent ovarian enlargement or ascites during or after infertility treatment should be carefully considered and managed

Abstract

Background: Monosodium glutamate (MSG) is used as a flavoring and food seasoning. Some studies have reported the oxidative effects of using this substance on various tissues.
Objective: This study has investigated the effects of MSG and the protective effect of vitamin C (vit C) on apoptosis of testicular germ cells and biochemical factors.
Materials and Methods: In this experimental study, 24 adult male Wistar rats were randomly divided into four groups: control (received distilled water), vit C group (150 mg/kg), experimental group 1 (MSG 3 gr/kg), experimental group 2 (MSG 3 gr/kg + vit C 150 mg/kg). The rats were gavaged for 30 days, and then were sacrificed, the right testis was isolated for biochemical examinations for the glutathione, malondialdehyde, and left testis used in histological experiments. Tunnel staining was used to determine the number of apoptotic cells.
Results: The results showed that apoptotic cells in the MSG group had a significant increase compared to the control group (P = 0.001), but the number of these cells in the MSG co-administered with vit C and vit C groups were significantly lower than the MSG group. Germinal epithelial thickness also decreased in MSG group compared to the control group.
Conclusion: MSG can lead to increase apoptotic changes in the germinal epithelial of the testicle, and vit C as an antioxidant can modify the pathological and biochemical changes induced by MSG.
