Abstract

Background: Auto antibodies to zona-pellucida (AZA) seem to be important autoantibodies implicated in reproduction, with substantial role in both endocrine and reproductive functions of the human ovary. There are some debates on the relation of AZA with infertility, repeated In Vitro Fertilization (IVF) attempts, and outcome of it. Objective: In this study, we assessed the presence of AZA in the follicular fluids (FFs) of women who underwent intra cytoplasmic sperm injection (ICSI), in relation to etiology of infertility and multiple puncture of ovaries. Materials and Methods: In this prospective study, follicular fluids were evaluated from 96 infertile women, (19-40 years old, 31.5�5.1), who were candidates for ICSI based on the etiology of infertility. From these 80 women had explained infertility whereas 16 had unexplained infertility. All FFs were evaluated for presence of AZA by ELISA test. Results: Twenty patients (20.8%) were positive for AZA in follicular fluid. In patients with unexplained infertility, AZA antibody in follicular fluid, was significantly higher than the group with proven etiology of infertility (p=0.001). In addition, 20.4 % of patients who had been punctured previously showed AZA in their FFs which is statistically similar to the patients who were punctured for the first time. Conclusions: The high incidence of AZA in infertile women, especially women with unexplained infertility has to be considered. Relation of the presence AZA and repeated puncture of ovaries is still debatable. Determinations of AZA are highly recommended in evaluation of infertile couples especially in patient with unexplained infertility

Abstract

Background: Endometriosis is defined as the growth of endometrial tissues in ectopic places outside the uterus. This disease has an important effect on the health and fertility of affected women. It’s etiology is not clearly known. For better understanding the pathophysiology of this disease, many researchers study on several aspects of the disease on animals.
Objective: In this experimental study endometriosis was induced in female rats surgically and then its side effects were investigated with special focus on adhesion formation that is a major problem in women with this disease.
Materials and methods: In Protestrous phase, female rats were randomly divided into two groups. In both groups, under intra peritoneal anesthesia, laparotomy was done and left horn and associated fat were removed. In experimented group (A), the removed endometrium was cut to six square pieces (2mm each) and they were sutured to the peritoneum, near ovaries and subcutaneous. In sham group (B), the same procedure was done for the fat tissues around the removed horn and the pieces were sutured to the same places. After 8 weeks, in Protestrous phase, clinical adhesion and size of implants were evaluated.
Results: The total mean size of implants was calculated in each group, and this was significantly larger in experimented group (25.4 mm versus 2 mm p=0.000). The mean diameter of implants that calculated for each site of implantation in experimented group were significantly larger in left peritoneum (p=0.002), followed by right (p=0.000) and left (p=0.000) ovaries. The endometrial tissues grew in 100% of implants in subcutaneous area. Clinical adhesions (Score ≥ 2) were detected in 7 out of 10 in experimented group and in 2 out 10 in control group. The number of Esterous cycle were similar in both groups.
Conclusion: Our study showed that after inducing endometriosis by surgical approach, only endometrial implants grew as a cystic structures and this is a unique aspect of endometrial cells. Our results showed that endometriosis had a direct effect on adhesion formation, not surgery alone and induction of this disease didn't have any adverse effect on ovarian function in female rats.

Abstract

Background: Matrigel (extracellular matrix) can improve the growth of many cell types in vitro.
Objective: The aim of the present study was to determine the effect of Matrigel on the development of 2-4 cells human embryos in culture.
Material and Methods: Surplus 2-4 cells human embryos, resulting from ICSI, were divided into two groups (control and test). Quality of embryos in both groups was morphologically similar. The test group (n=140) was cultured in Hams’ F10 supplemented with 10% human serum albumin and 150 µl liquid Matrigel. The control group (n=140) was cultured in the same medium devoid of Matrigel. Embryos were cultured for an additional 4 days and their morphology was assessed every 24 hours. Both groups were then statistically compared.
Results: The percentage of the human embryos that reached the morula stage in the control and test groups were 79.2% and 80%, respectively (p>0.05).  However, 36.4% of embryos reached the blastocyst stage in the test group as compared to 5.7% in the control group after 144 hours in culture. This difference was statically significant (p <0.01). In addition, culture of embryos on Matrigel and medium versus medium alone significantly improved in vitro hatching (25.7% versus 3.5%; p <0.01).
Conclusion: Matrigel at low concentration enhances human blastocyst formation and hatching in vitro.

Abstract

Background: Immune system disturbances have an important role in endometriosis which may lead to infertility. It seems that inflammatory cytokines specially tumor necrosis factor alpha (TNF-a) which were produced by activated macrophages have an important role in pathology of endometriosis.  Based on this theory, anti TNF-a  drugs like pentoxifylline (PX) are suggested as new drugs for Endometriosis.            
Objective: This experimental study has been done on female rats to determine the effect of PX on the endometrial implants and leukocytes in serum.
Material and Methods: In proestrous phase, one horn of rat’s bicorn uterus was removed surgically and the endometrium was implanted to different places as follows: subcutaneous, peritoneum and near ovaries. After two months observation, female rats divided into two groups randomly. In treated group (n=10) PX (5mg/kg twice a day) and in control group (n=10), normal saline (same dose) were injected subcutaneously. Then, via second laparotomy and in the same phase of the cycles, the size of implants and the amount of leukocytes in serum were measured.
Results: In treated group compared with control, the size of implants was decreased significantly in right subcutaneous  (8.05mm vs 13.50mm) p<0.01, left subcutaneous (7.64 mm vs 14mm) p<0.01, right ovary (6.64 mm vs 15.22mm) p<0.001 and left ovary (7.18 mm vs 14.56 mm) p<0.005. In treated group, the total leukocyte count (5259.54 ± 178.78 vs 15833.33 ±  259.27) p<0.02 was decreased. The number of esterous cycle was similar in both groups.
Conclusion: PX can reduce the size of endometrial implants as well as leukocyte count.

Abstract

Background: Evidences suggest an association between the prevalence of thyroid peroxidase (anti-TPO) and anti thyroglobulin (anti-Tg) with recurrent abortions and infertility. Iodine deficiency was once endemic in Iran and little data is available about the prevalence of these antibodies in different groups of fertile or infertile individuals.
Objective: This case control study was designed to compare the presence of anti-TPO and anti-Tg in four groups of women to reveal their role in the etiology of recurrent abortion and infertility.
Materials and Methods: Four groups of euthyroid women referring to Avicenna Infertility Clinic in Tehran were selected; 95 cases as fertile controls and 70, 78 and 137 cases with male and female factor infertility and recurrent abortion respectively. TSH, anti-TPO and anti-Tg were evaluated by chemiluminescent immunoassay.
Results: The prevalence of the above mentioned autoantibodies in euthyroid controls was about 25% and the percentage of people with an anti-Tg &gt;500 was two times bigger in the abortion group compared to the control group (p&lt;0.05) and the proportion of people with an anti-Tg &gt;500 in younger cases in the abortion group was significantly higher than the rest of the cases (p&lt;0.05). Anti-TPO distribution had no significant differences. Conclusion: There were no statistically significant differences among four groups. It seems that more comprehensive studies are needed to reach a common conclusion about thyroid autoantibodies in women with recurrent abortions in different groups and different parts of Iran. In addition, dividing the recurrent abortion and infertility groups on the basis of their etiologies could be effective.

Abstract

Background: Cryptorchidism is a common malformation in neonates; surgery or medical treatments are applied during childhood. Untreated cryptorchid testes are in the risk of intratubular germ cell neoplasia (IGCN) and consequently invasive testicular tumors which could be shown by immunohistochemistry staining for placental like acid phosphatase (PLAP) marker.
Objective: We designed this study to know the prevalence of IGCN in untreated cryptorchid testes of infertile men, in our infertility center as a refferal center.
Materials and Methods: In this cross-sectional study we assessed H&E slides of testicular samples of 13 adult infertile patients with impalpable intra-abdominal testes seeking infertility treatment; then we stained them by PLAP marker.
Results: Three (23.08%) samples were positive for PLAP marker means presence of IGCN in testis. One of them showed seminoma besides IGCN. Conclusion: According to the results of this study and the fact that there are adult untreated cryptorchid patients in our country yet, it is suggested to pay more attention in clinical examination, assessment and follow up of such patients for malignancy screening.

Abstract

Background: Spermatogonial stem cells (SSCs), a subset of undifferentiated type A spermatogonia, are the foundation of complex process of spermatogenesis and could be propagated in vitro culture conditions for long time for germ cell transplantation and fertility preservation.
Objective: The aim of this study was in vitro propagation of human spermatogonial stem cells (SSCs) and improvement of presence of human Germ Stem Cells (hGSCs) were assessed by specific markers POU domain, class 5, transcription factor 1 (POU5F1), also known as Octamer-binding transcription factor 4 (Oct-4) and PLZF (Promyelocytic leukaemia zinc finger protein).
Materials and Methods: Human testicular cells were isolated by enzymatic digestion (Collagenase IV and Trypsin). Germ cells were cultured in Stem-Pro 34 media supplemented by growth factors such as glial cell line-derived neurotrophic factor, basic fibroblast growth factor, epidermal growth factor and leukemia inhibitory factor to support self-renewal divisions. Germline stem cell clusters were passaged and expanded every week. Immunofluorecent study was accomplished by Anti-Oct4 antibody through the culture. The spermatogonial stem cells genes expression, PLZF, was studied in testis tissue and germ stem cells entire the culture.
Results: hGSCs clusters from a brain dead patient developed in testicular cell culture and then cultured and propagated up to 6 weeks. During the culture Oct4 were a specific marker for identification of hGSCs in testis tissue. Expression of PLZF was applied on RNA level in germ stem cells.
Conclusion: hGSCs indicated by SSCs specific marker can be cultured and propagated for long-term in vitro conditions.

Abstract

Background: Human pathogens that can cause infertility may also affect sperm count and quality. Viral infections can be considered as direct and/or indirect cause of male factor infertility.
Objective: Our goal was to investigate the prevalence of herpes simplex virus in the semen of infertile men attending the Avicenna Infertility Clinic, and to compare it with the herpes virus serology results.
Materials and Methods: This cross sectional study was conducted during 2009-2010. Infertile men participating without any clinical signs of infection with herpes simplex virus, and no obvious cause for their infertility were included. Semen and blood samples were used for Polymerase Chain Reaction (PCR) and serologic testing for these people. Two samples were collected: one ml semen sample to verify the existence of genital herpes simplex virus in infertile men, and blood samples of 217 individuals tested for antibodies to herpes simplex virus. Data were analyzed by SPSS 16.
Results: According to the PCR results of semen samples the prevalence of herpes simplex in semen was 12% and serologic test showed 3.2% prevalence within blood. Nine to 10% of IgM negative were PCR positive and only 2-3% of IgM positive were PCR positive. Between herpes serologic studies with positive controls and negative controls by using both tests, there was a significant positive relationship (r=0.718 and p<0.001). The relationship between semen PCR test results and serological survey of herpes patients with a negative control in both Pearson and Spearman tests was positive and significant (r=0.229 and p=0.001). Correlation between the PCR results of semen samples with two positive control subjects and a positive IgM test was statistically confirmed (r=0.235 and p<0.001).
Conclusion: We recommend that if there is suspicion to herpes simplex as a microorganism that theoretically could impact semen parameters and cause infertility it is prudent to use PCR technique on semen sample rather than ELISA on serum.

Abstract

Background: Endometriosis, a common chronic inflammatory disorder, is defined by the atypical growth of endometrium- like tissue outside of the uterus. Secretory phospholipase A2 group IIa (sPLA2-IIa) and fatty acid binding protein4 (FABP4) play several important roles in the inflammatory diseases.
Objective: Due to reported potential anti-inflammatory effects of ω-3 and ω-6 fatty acids, the purpose of the present study was to investigate the effects of ω-3 and ω-6 polyunsaturated fatty acids (PUFAs) on fatty acid binding protein 4 and extracellular secretory phospholipase A2IIa in cultured endometrial cells.
Materials and Methods: Ectopic and eutopic endometrial tissues obtained from 15 women were snap frozen. After thawing and tissue digestion, primary mixed stromal and endometrial epithelial cell culture was performed for 8 days in culture mediums supplemented with normal and high ratios of ω-3 and ω-6 PUFA. sPLA2-IIa in the culture medium and FABP4 level was determined using enzyme immuno assay (EIA) technique.
Results: Within ectopic endometrial cells group, the level of cellular FABP4 and extracellular sPLA2-IIa were remarkably increased under high ω-3 PUFA exposure compared with control condition (p=0.014 and p=0.04 respectively).
Conclusion: ω-3 PUFAs may increase the level of cellular FABP4 and extracellular sPLA2-IIa in ectopic endometrial cells, since sPLAIIa and FABP4 may affect endometriosis via several mechanisms, more relevant studies are encouraged to know the potential effect of increased cellular FABP4 and extracellular sPLA2-IIa on endometriosis.

Abstract

Background: One of the promising methods in fertility preservation among women with cancer is cryopreservation of ovarian cortex but there are many drawbacks such as apoptosis and considerable reduction of follicular density in the transplanted ovary. One solution to reduce ischemic damage is enhancing angiogenesis after transplantation of ovarian cortex tissue.
Objective: The aim of this study was to investigate the effect of Setarud, on angiogenesis in transplanted human ovarian tissue.
Materials and Methods: In this case-control study, twenty-four nude mice were implanted subcutaneously, with human ovarian tissues, from four women. The mice were randomly divided into two groups (n=12): the experimental group was treated with Setarud, while control group received only vehicle. Each group was divided into three subgroups (n=4) based on the graft recovery days post transplantation (PT). The transplanted fragments were removed on days 2, 7 and 30 PT and the expression of Angiopoietin-1, Angiopoietin-2, and VEGF at both gene and protein levels and vascular density were studied in the grafted ovarian tissues.
Results: On the 2nd and 7th day PT, the level of Angiopoietin-1 gene expression in case group was significantly lower than that in control group, while the opposite results were obtained for Angiopoietin-2 and VEGF. These results were also confirmed at the protein level. The density of vessels in Setarud group elevated significantly on day 7 PT compared to pre-treatment state.
Conclusion: Our results showed that administration of Setarud may stimulates angiogenesis in transplanted human ovarian tissues, although further researches are needed before a clear judgment is made.

Abstract

Nuclear transfer procedures have been recently applied for clinical and research targets as a novel assisted reproductive technique and were used for increasing the oocyte activity during its growth and maturation. In this review, we summarized the nuclear transfer technique for germinal vesicle stage oocytes to reconstruct the maturation of them. Our study covered publications between 1966 and August 2017. In result utilized germinal vesicle transfer techniques, fusion, and fertilization survival rate on five different mammalian species are discussed, regarding their potential clinical application. It seems that with a study on this method, there is real hope for effective treatments of old oocytes or oocytes containing mitochondrial problems in the near future.

Abstract

Background: Sperm processing methods separate motile sperms with good morphology from dead and abnormal forms of sperms, immature germ cells, and non-sperm cells.
Objective: The propose of this study was to compare the efficacy of upstream and swim-up processing techniques to separate sperms with the high quality especially in relation to sperm chromatin integrity.
Materials and Methods: This experimental study used semen samples from 60 normozoospermic men. Specimens were divided into equal aliquots for processing by swim up (group A), and upstream (group B) methods and compare with control by raw semen (group C). Sperm concentration, morphology, motility, DNA fragmentation and chromatin maturation were measured in these three groups.
Results: The results revealed that sperm concentration in the swim up samples was significantly greater than upstream samples (p≤0.04). as addition, motile sperm recovery including the percentage of progressive motility and a total number of motile sperm was better in the swim-up compared to an upstream method and raw semen (p≤0.001). The cell debris and seminal fluid were equally removed by both methods and the percentage of normal forms was also similar in both procedures (p≥0.4). In addition, sperm DNA fragmentation and chromatin maturation were not significantly different between the three groups (p≥0.1).
Conclusion: According to results, apparently the upstream method had no significant efficiency to separate good quality sperms compare to swim up. Therefore, swim up seems to be a simple, inexpensive, reliable and widely available method with an efficient yield to separate motile sperm with good morphology and better chromatin integrity for insemination in the infertility clinics.
