Compared with open and laparoscopic varicocele treatment microsurgical varicocelectomy has the advantages of no hydrocele formation, a lower incidence of recurrent varicocele, and better improvement in sperm count and motility.

The success rate of ESWL for the treatment of renal stones could be predicted by stone size, location and number, radiological renal features and congenital renal anomalies.

Sperm DNA fragmentation (SDF) has emerged as an important biomarker in the assessment of male fertility potential with contradictory results regarding its effect on ICSI. The aim of this study was to evaluate intracytoplasmic sperm injection (ICSI) outcomes in male patients with high SDF using testicular versus ejaculated spermatozoa. This is a prospective study on 36 men with high-SDF levels who had a previous ICSI cycle from their ejaculates. A subsequent ICSI cycle was performed using spermatozoa retrieved through testicular sperm aspiration. Results of the prior ejaculate ICSI were compared with those of the TESA-ICSI. The mean (SD) SDF level was 56.36% (15.3%). Overall, there was no difference in the fertilization rate and embryo grading using ejaculate and testicular spermatozoa (46.4% vs. 47.8%, 50.2% vs. 53.4% respectively). However, clinical pregnancy was significantly higher in TESA group compared to ejaculated group (38.89% [14 of 36] vs. 13.8% [five of 36]). Moreover, 17 live births were documented in TESA group, and only three live births were documented in ejaculate group (p < .0001). We concluded that the use of testicular spermatozoa for ICSI significantly increases clinical pregnancy rate as well as live-birth rate in patients with high SDF.

BackgroundPremature ejaculation (PE) is a highly prevalent sexual dysfunction among patients with diabetes mellitus (DM). Despite this, the underlying mechanism of this association is poorly understood. In this study, we aimed to investigate the prevalence of PE in a group of patients with DM and explore possible associations linking both conditions together.MethodsThis was a prospective study of subjects recruited with advertisement pamphlets and whose sexual function was assessed using the international index of erectile function-5 (IIEF-5) and the Arabic index of premature ejaculation (AIPE) questionnaires together with stopwatch measured intravaginal ejaculatory latency time (ELT). Participants were divided into two groups; group A subjects had DM and group B were healthy adult males.ResultsA total of 488 subjects were recruited. Group A included 199 (40.8%) subjects, while group B included 289 (59.2%). The prevalence of PE and ED was significantly higher in group A subjects (P<0.001). Mean ELT ± standard deviation (SD) was 3.6±2.7 in group A versus 4.3±2.8 in group B (P<0.014). Diabetic patients with erectile dysfunction (ED) showed a significantly higher incidence of PE with significantly shorter ELT.ConclusionsPE is more prevalent in diabetic patients. DM is a multi-systemic disorder with complications that could help explain the pathophysiology of PE.

Seminal oxidative stress (OS) is well-known to affect male fertility status. The discrepancy in OS measurement has hindered its clinical use as a quality indicator for semen. Some tests measured single markers of oxidants or reductants, leading to lack of standardization of results. Oxidation-reduction potential (ORP) is a better representative for OS as it provides an overall measure of the activity of both oxidants and reductants. ORP assessment by MiOXSYS has been introduced as a measure of OS with high specificity in differentiating fertile from infertile semen samples. This is a retrospective study comparing data from semen analysis and ORP measurements between two andrology laboratories in the USA and Qatar over a period of 12 months. The same protocol was followed by both laboratories. The USA dataset contained 194 patients and 51 fertile donors, while the Qatar dataset contained 400 patients and 50 fertile donors. In both datasets and in the combined dataset, the infertile group had significantly lower sperm concentration, total and progressive motility, and normal morphology as well as higher ORP levels compared to fertile men (p< 0.05). When comparing data from both centers, the infertile group showed significant difference between both datasets regarding progressive motility and morphology (p < 0.001). Also, the percentage of patients with abnormal semen volume, sperm count, total and progressive motility were significantly different between both datasets (p < 0.05). ORP levels showed no significant difference between both datasets (p < 0.08). ROC analysis indicated that ORP cutoff value of 1.42 mV/10 /mL in the USA group, Qatar group, and combined dataset can accurately differentiate fertile from infertile semen groups. Although other semen parameters showed significant differences between the two centers, ORP remained consistent in both datasets individually or in combined data. This proves its reproducibility and reliability.

BackgroundLarge databases focused on genetic susceptibility to prostate cancer have been accumulated from population studies of different ancestries, including Europeans and African-Americans. Arab populations, however, have been only rarely studied.MethodsUsing Affymetrix Genome-Wide Human SNP Array 6, we conducted a genome-wide association study (GWAS) in which 534,781 single nucleotide polymorphisms (SNPs) were genotyped in 221 Tunisians (90 prostate cancer patients and 131 age-matched healthy controls). TaqMan® SNP Genotyping Assays on 11 prostate cancer associated SNPs were performed in a distinct cohort of 337 individuals from Arab ancestry living in Qatar and Saudi Arabia (155 prostate cancer patients and 182 age-matched controls). In-silico expression quantitative trait locus (eQTL) analysis along with mRNA quantification of nearby genes was performed to identify loci potentially cis-regulated by the identified SNPs.ResultsThree chromosomal regions, encompassing 14 SNPs, are significantly associated with prostate cancer risk in the Tunisian population (P = 1 × 10-4 to P = 1 × 10-5). In addition to SNPs located on chromosome 17q21, previously found associated with prostate cancer in Western populations, two novel chromosomal regions are revealed on chromosome 9p24 and 22q13. eQTL analysis and mRNA quantification indicate that the prostate cancer associated SNPs of chromosome 17 could enhance the expression of STAT5B gene.ConclusionOur findings, identifying novel GWAS prostate cancer susceptibility loci, indicate that prostate cancer genetic risk factors could be ethnic specific.

Xanthogranulomatous orchitis is an extremely rare inflammatory non-neoplastic destructive lesion of the testis. We report a 44-year-old man who presented with right scrotal swelling and two discharging sinuses. Testicular tumor markers were normal. Scrotal ultrasound showed heterogeneous testicular areas and irregular margin of the tunica. Surgical exploration revealed infected , unhealthy testicular tissue with necrosis and tumor-like lesion. Orchidectomy was done and histopathology showed xanthogranulomatous orchitis.

ObjectiveTo study the types and incidence of chromosomal abnormalities in infertile men with azoospermia and severe oligozoospermia in Qatar, and to compare the hormonal changes, testicular sperm retrieval rate, and intracytoplasmic sperm injection (ICSI) outcome between patients with chromosomal abnormalities and patients with idiopathic infertility.Patients and methodsThis study involved the retrospective chart review of 625 infertile male patients attending an academic tertiary medical centre in Qatar. Retrieved information included data on medical history, family history, clinical examination, semen analysis, initial hormonal profiles, and genetic studies, ICSI, and sperm retrieval results.ResultsThe incidence of chromosomal abnormalities was 9.59% (10.6% amongst Qatari patients, 9.04% amongst non-Qataris). About 63.6% of the sample had azoospermia, of whom 10.8% had chromosomal abnormalities. Roughly 36.4% of the sample had oligozoospermia, of whom 7.5% had chromosomal abnormalities. There were no differences between patients with chromosomal abnormalities and those with idiopathic infertility for demographic and infertility features; but for the hormonal profiles, patients with idiopathic infertility had significantly lower luteinising hormone and follicle-stimulating hormone values. For ICSI outcomes, patients with chromosomal abnormalities had a significantly lower total sperm retrieval rate (47.4% vs 65.8%), surgical sperm retrieval rate (41.2% vs 58.1%), and lower clinical pregnancy rate (16.7% vs 26.6%) when compared to the idiopathic infertility group.ConclusionThe incidence of chromosomal abnormalities in Qatar as a cause of severe male infertility is within a similar range as their prevalence internationally.
