Abstract

Background: In patients with non-obstructive azoospermia (NOA), vital spermatozoa from the tissue is obtained from testes by enzymatic treatment besides the mechanical treatment.
Objective: To increase the sperm recovery success of testicular sperm extraction (TESE), with enzymatic digestion if no sperm is obtained from testis tissue by mechanical method.
Materials and Methods: Tissue samples were collected from 150 men who presented with clinical and laboratory data indicating NOA by means of TESE and micro dissection TESE methods. Initially, mature spermatozoa were examined for by mechanical extraction technique shredding the biopsy fractions. In cases whom no spermatozoa was observed after maximum 30 min of initial searching under the inverted microscope, the procedure was followed by enzymatic digestion using DNaseI and collagenase type IV. Surgery type, pathology, AZF, karyotype, hormones and testis size were compared in patients.
Results: Of 150 cases with NOA, conventional mincing method extended with enzymatic treatment yielded successful sperm recovery in 13 (about 9%) patients. Comparison of parameters revealed that level of FSH and LH were significantly different (p=0.04 and 0.08 respectively) between two groups that response negative and positive to enzymatic digestion.
Conclusion: The combination of conventional TESE and enzymatic digestion is an effective method to recover spermatozoa. The benefit of the mincing combined with enzyme to sperm retrieval for NOA firstly shorten the mechanical searching time, leading to minimizing further cellular damage as well as exposure to external conditions, and secondly reduce the number of cases with sperm recovery failures. Also, the serum level of FSH and LH are factors that influence the chance of sperm retrieval.

Abstract

Background: Cytomegalovirus (CMV) is a prevalent infection in humans. Recent studies have shown the role of CMV infection in male infertility disorder.
Aim: Here we aimed to study the role of CMV infection in men with idiopathic infertility.
Materials and Methods: We performed a case-control study of CMV serology in 200 patients attending male infertility clinic of a university hospital. There were 154 men diagnosed with infertility and 46 men without infertility. The patients were asked to donate their sperm, blood, and urine. The presence of CMV infection was studied using quantitative polymerase chain reaction.
Results: CMV infection was present in 25 of all the studied participants. Controls had a higher sperm count and sperm motility and sperm morphology compared to patients. There were no significant differences in the studied variables between those with and without CMV infection, nor in patients, neither in controls. Sperm morphology was negatively correlated with cigarette smoking (r=-0.15; p<0.03). Even though the prevalence of CMV infection was higher in patients with infertility in control and patient (5/46 vs. 20/154) respectively, this was not statistically significant.
Conclusion: We did not show a significant role for CMV infection in male infertility. Based on the previous studies, it could be assumed that CMV infection is an important part of the male infertility and its treatment would improve the sperm quality, however this was not confirmed by the present study.

Abstract

Background: Septins are an evolutionary conserved group of GTP-binding and filament-forming proteins that have diverse cellular roles. An increasing body of data implicates the septin family in the pathogenesis of diverse states including cancers, neurodegeneration, and male infertility.
Objective: The objective of the study was to evaluate the expression pattern of Septin14 in testis tissue of men with and without spermatogenic failure.
Materials and Methods: The samples retrieved accessible random between infertile men who underwent diagnostic testicular biopsy in Royan institute. 10 infertile men with obstructive azoospermia and normal spermatogenesis and 20 infertile men with non-obstructive azoospermia were recruited for real-time reverse transcription (RT)-PCR analysis of the testicular tissue. Total RNA was extracted with trizol reagent.
Results: Comparison of the mRNA level of septin14 revealed that in tissues with partial (n=10) or complete spermatogenesis (n=10), the expression of septin 14 was significantly higher than sertoli cell only tissues.
Conclusion: The testicular tissues of men with hypospermatogenesis, maturation arrest and sertoli cell only had lower levels of septin 14 transcripts than normal men. These data indicates that Septin 14 expression level is critical for human spermatogenesis.

Abstract

Background: Male infertility is a multifactorial disorder, which affects approximately 10% of couples at childbearing age with substantial clinical and social impact. Genetic factors are associated with the susceptibility to spermatogenic impairment in humans. Recently, SEPT12 is reported as a critical gene for spermatogenesis. This gene encodes a testis specific member of Septin proteins, a family of polymerizing GTP-binding proteins. SEPT12 in association with other Septins is an essential annulus component in mature sperm. So, it is hypothesized that genetic alterations of SEPT12 may be concerned in male infertility.
Objective: The objective of this research is exploration of new single nucleotide polymorphism G5508A in the SEPT12 gene association with idiopathic male infertility in Iranian men.
Materials and Methods: In this case control study, 67 infertile men and 100 normal controls were analyzed for genetic alterations in the active site coding region of SEPT12, using polymerase chain reaction sequencing technique. Fisher exact test was used for statistical analysis and p<0.05 was considered as statistically significant.
Results: Genotype analysis indicated that G5508A polymorphic SEPT12 alleles were distributed in three peaks of frequency in both control and diseases groups. Categorization of the alleles into (GG), (GA), (AA) types revealed a significant difference between infertile patients (azoospermic and asthenospermic) and normal controls (p=0.005).
Conclusion: According to our finding we suggest that G5508A polymorphism in SEPT12 gene can affect spermatogenesis in men, the opinion needs more investigation in different populations.

Abstract

Background: The availability of testis specific genes will be of help in choosing the most promising biomarkers for the detection of testicular sperm retrieval in patients with non-obstructive azoospermia (NOA). Testis specific chromodomain protein Y 1 (CDY1) is a histone acetyltransferase which concentrates in the round spermatid nucleus, where histone hyperacetylation occurs and causes the replacement of histones by the sperm-specific DNA packaging proteins, TNPs and PRMs.
Objective: The aim was to evaluate CDY1 gene as a marker for predicting of successful sperm retrieval in NOA patients.
Materials and Methods: This research was conducted on 29 patients with NOA who had undergone testicular sperm extraction (TESE) procedure. NOA patients were subdivided into patients with successful sperm retrieval (NOA+, n=12) and patients with unsuccessful sperm retrieval (NOA-, n=17). Relative expression of CDY1 gene and chromatin incorporation of CDY1 protein were measured by quantitative real-time polymerase chain reaction (qRT-PCR) and ELISA assay, respectively.
Results: Quantification of mRNA relative expression and incorporation of CDY1 protein in chromatin showed significant lower expressions and protein levels of CDY1 in testis tissues of NOA- in comparison to NOA+ group.
Conclusion: The findings in this study demonstrated a correlation between the low levels of CDY1 function and unsuccessful sperm recovery in the testicular tissues of NOA- compared to NOA+ patients. Therefore, it can be reasonable to consider CDY1 as a potential biomarker for predicting the presence of spermatozoa, although the claim needs more samples to be confirmed.

Abstract

Background: Although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions.
Objective: This study was designed to investigate the effects of ginger (Zingiber officinale) on sperm DNA fragmentation (SDF) in infertile men.
Materials and Methods: This randomized double-blind, placebo-controlled trial with a 1:1 allocation was performed on 100 infertility treatment candidates who were admitted to Royan Institute for Reproductive Biomedicine, Tehran, Iran. Patients were randomly assigned to receive one of two treatments: ginger and placebo. Patients were given a 3-month oral treatment (members received capsules containing 250 mg of ginger powder twice a day in ginger and a placebo in other group). Before and after treatment, standardized semen samples were obtained to determine sperm concentration, motility, and SDF according to World Health Organization.
Results: There was no significant difference between two groups regarding SDF at baseline (53.48. 95%CI: 37.95-69.02) in cases and (56.75, 95%CI: 40.01-73.5) in controls. The average positive percentage of SDF in patients receiving ginger (17.77, 95%CI: 6.16-29.39) was lower compared with placebo (40.54, 95%CI: 23.94-57.13) after three month of treatment (p=0.02). In multivariate analysis, SDF was significantly lower in patients receiving ginger compared with placebo (mean difference: 3.21, 95%CI: 0.78-5.63, p=0.009). There were no significant differences between two groups regarding to semen parameters.
Conclusion: The present study has demonstrated that ginger in a controlled study of efficacy was effective in decreasing SDF in infertile men.

Abstract

Background: The role of the screening protocol for viral hepatitis and human immuunodeficiency virus (HIV) infections among infertile couples were seldom investigated.
Objective: The present study was performed to assess the prevalence of hepatitis B virus (HBV), hepatitis C virus (HCV) and HIV infections among infertile couples referring to infertility clinic of Royan Institute.
Materials and Methods: This analytical cross-sectional study was performed on 21673 infertile couples referring to infertility clinic of Royan Institute between 2009 and 2014. Serological findings for viral hepatitis B, C and HIV infection were gathered herewith demographic data of the study participants through the study checklist. Ultimately, 302 couples who had at least one positive result in their serological tests were included in the statistical analysis. Results: The HBV and HCV infections prevalence among study participants were 0.57% and 0.148% respectively; only two cases had HIV infection. HBV and HCV infections prevalence had significant association with the gender of participants, but there was no significant relationship between these infections and infertility types.
Conclusion: Viral hepatitis infections screening among infertile couples undergoing assisted reproductive techniques needs more attention.
