RESUMEN
In forensic investigations, semen samples are a common form of biological evidence, especially in cases involving sexual assault. Therefore, accurately estimating the age of an individual is crucial in criminal cases. This study presents a novel age estimation model based on semen-specific CpG methylation patterns. A multiplex panel was developed, consisting of 12 CpG sites (PARP14, C5orf25, cg23488376, MXRA5, PFKFB3, DLL1, NOX4, cg12837463, TTC7B, KCNA7, NKX2-1, and SYNE4), which exhibit strong correlations with age. Additionally, this study investigates the resilience of these methylation markers under simulated environmental challenges. We collected ejaculate samples from a diverse cohort of 115 male individuals, aged 20-71 years, who underwent deoxyribonucleic acid extraction and bisulfite conversion. Methylation levels of the selected CpG sites were assessed using a SNaPshot assay, which revealed significant correlations with chronological age. We developed and validated two robust age estimation models through stepwise and enter regression analyses, achieving reliable accuracy with mean absolute errors ranging from 3.81 to 4.1 years. Additionally, the study also investigated the robustness of semen stains under diverse environmental conditions, including fabric type, washing, hematin exposure, and UV-C light. The selected methylation markers demonstrated remarkable resilience despite the challenges posed by washing procedures and environmental exposure, confirming their potential for age estimation in forensic genetics. This research presents successful age estimation models, emphasizing the strong correlations between methylation levels and chronological age. The proposed methodology's accuracy is affirmed through model validation on an independent test set, while also highlighting the resilience of semen stains on fabrics under varying storage and washing conditions.
RESUMEN
AIMS OF THE STUDY: The aim of this study was to investigate the impact of testosterone deficiency on cognitive functions in metastatic prostate cancer patients receiving androgen deprivation therapy (ADT). METHODS: In this multicentric prospective study, 65 metastatic prostate cancer patients were evaluated. Demographic and clinical data were recorded. Cognitive functions were assessed using the Symbol Digit Modalities Test, the California Verbal Learning Test Second Edition, the Brief Visuospatial Memory Test-Revised, and the Trail Making Test. Depressive symptoms were assessed using the Beck Depression Inventory. Cognitive functions and depressive symptoms were recorded before the androgen deprivation therapy and at the 3- and 6-month follow-ups. RESULTS: At the basal cognitive assessment, the mean Symbol Digit Modalities Test, the California Verbal Learning Test Second Edition, the Brief Visuospatial Memory Test-Revised scores were 25.84 ± 17.54, 32.68 ± 10.60, and 17.63 ± 11.23, respectively, and the mean time for the Trail Making Test was 221.56 ± 92.44 seconds, and were similar at the 3-month, and 6-month controls (P > .05). The mean pretreatment, third and sixth month testosterone levels were 381.40 ± 157.53 ng/dL, 21.61 ± 9.09 ng/dL and 12.25 ± 6.45 ng/dL (P < .05), and the total PSA levels were 46.46 ± 37.83 ng/mL, 1.41 ± 3.31 ng/mL and 0.08 ± 0.14 ng/mL (P < .05), respectively. CONCLUSION: The ADT in patients with metastatic prostate cancer does not affect patients' cognitive functions and depressive symptoms. However, further prospective randomised studies with higher cohorts and longer follow-up periods are needed.

BACKGROUND: Alpha-adrenergic antagonist treatment for benign prostatic hyperplasia (BPH) and drug-related sexual side effects are frequent in aging men. AIM: To investigate functional changes in erectile and ejaculatory aspects of male sexuality under Silodosin 8 mg per day treatment for BPH. METHODS: Sexually active patients diagnosed with BPH and who initiated Silodosin treatment were the subjects of the study. The International Prostate Symptom Score, premature ejaculation patient profile (PEP-male) questionnaire, Sexual Health Inventory for Men (SHIM) questionnaire, and estimated intravaginal ejaculation latency time (IELT) values of the participants were used to evaluate sexual functions. Data evaluation was performed in 8 urology clinics retrospectively. OUTCOMES: Participant ratings for SHIM, PEP, and estimated IELT were the primary outcome measures in the study. RESULTS: Among 187 recruited patients, data of 98 patients, who completed the trial period in the study, were eligible. The median age of the eligible participants who completed the trial period for 3 months was 59.5 years (range 45-82). 16 patients of 187 (8%) reported a desire for drug withdrawal for anejaculation during the recruitment period. 46 (46.9%) and 49 (50%) patients reported anejaculation in the first and third month of the treatment, respectively. De novo erectile dysfunction was noticed in 15 patients (15.3%). There was a significant increase in the estimated IELT of subjects in both the first (P = .01) and third (P = .002) month. SHIM-1 (P = .008), SHIM-total (P = .009), and PEP scores (P = .008) were also improved in the third month of the treatment. Neither baseline patient characteristics nor changes in the International Prostate Symptom Score after treatment predicted final outcomes with multivariable analysis. The subgroup analysis of participants who reported "anejaculation" also revealed better outcomes compared with participants ejaculating naturally in the third month as per SHIM ratings. CLINICAL IMPLICATIONS: Despite several male patients having dry orgasms due to Silodosin-induced anejaculation, the majority experienced improved erectile function. STRENGTHS & LIMITATIONS: The present study demonstrated pioneering results while investigating both erectile and ejaculatory dimensions of the male sexual function during Silodosin treatment for BPH. However, lack of partner evaluation, low follow-up rates, and lack of knowledge about reasons why subjects are lost to follow-up after drug initiation have limited our interpretation. CONCLUSION: Most patients using Silodosin 8 mg per day for BPH treatment experienced improvement in their erectile function, estimated IELT, and premature ejaculation profile in the third month of the treatment. Underlying mechanisms and reasons for individual differences necessitate further investigation. Cihan A, Kazaz IO, Yildirim Ö, et al.

BACKGROUND: Testicular torsion is an emergency condition in which spermatogenesis may be irreversibly damaged. There have been controversial results about the effect of testicular torsion on steroidogenesis. We aimed at investigating the effect of testicular torsion on steroidogenesis. MATERIAL AND METHODS: A total of 40 adult male rats were divided into 4 groups. Left testicles were removed in all groups. Right testicles were torsioned and remained in the torsion position for 1, 3 and 5 h in study groups, whereas no torsion was performed in control. Serum luteinizing hormone (LH) and total testosterone (TT) levels were measured on the 3rd and 30th days of surgery and orchiectomy was performed on the 30th day of testicular torsion for histopathological evaluation. RESULTS: TT levels of study groups were significantly lower than that of the control group on the 3rd day of torsion. LH of study groups was higher than that of the control group, but the difference was significant only in the 5 h-torsion group. The total number of Leydig cells increased in 1- and 3-h groups, whereas it decreased in the 5-hour group. CONCLUSION: Testosterone production and Leydig cell functions significantly decreased after 5 h torsion in the rat model. The duration of torsion less than 5 h yielded partial dysfunction on steroidogenesis.

Adjunctive residual curvature correction by plaque incision and grafting with a sutureless graft during inflatable penile prosthesis (IPP) implantation in patients with Peyronie's disease (PD) is our preferred technique. The PICS Technique (Penile Implant in Combination with the Sealing Technique) uses a self-adhesive collagen fleece (TachoSil®, Corza Medical, MA, USA) to cover the defect after plaque incision. The graft does not require sutures improving operative speed and avoiding needle stick of the implant cylinders. In this article, we present the first known application worldwide of a Rigicon Infla10® X (Rigicon, Ronkonkoma, NY, USA) device to Peyronie's ventral curvature. The patient's residual curvature of 80° after implantation was corrected by PICS through an additional subcoronal incision. At the conclusion of surgery, the penis was totally straight and rigid. No intra- and postoperative complications occurred. At the early follow-up of 12 weeks postoperatively, the patient was able to inflate and deflate the device and sexual intercourse was possible. A combination of the Rigicon Infla10® X and the PICS Technique represents a safe and successful approach for residual curvature correction during IPP in patients with ventral Peyronie's curvature. The Rigicon Infla10® X device showed excellent rigidity, and controlled expansion of the X cylinders means it can be used with the PICS Technique without restrictions. Early results are promising. Long-term follow-up and more patients are needed.
RESUMEN
OBJECTIVE: Spermatozoa are susceptible to oxidative radicals when antioxidant defenses are inadequate. The extent to which oxidative radicals contribute to sperm damage in patients with acromegaly remains unclear. This study aimed to investigate and elucidate this relationship. METHODS: The overall status of oxidants and antioxidants in both seminal plasma and serum of patients with acromegaly compared to a control group of healthy individuals was investigated. In addition, sperm parameters, including important measures such as growth hormone and insulin-like growth factor-1 concentrations. RESULTS: Twenty-two patients with acromegaly with controlled disease and 14 healthy controls were included. The total oxidant status was significantly higher in the semen samples of the patients with acromegaly. A negative correlation was found between sperm total oxidant status and total sperm count and sperm concentration. Similarly, a negative correlation was found between the total sperm count and the sperm oxidative stress index. In individuals diagnosed with acromegaly, there was a statistically significant increase in sperm growth hormone levels. Conversely, the level of insulin-like growth factor 1 was significantly increased in the sperm of the control group, which consisted of healthy individuals. The correlation analysis revealed a significant relationship between venous total oxidant status and growth hormone levels in semen. CONCLUSION: The elevated levels of reactive oxygen radicals in individuals with acromegaly suggest a possible link between oxidative stress and its effects on semen quality.
RESUMEN
BACKGROUND: We sought to determine whether two soluble forms with different size of mtDNA are linked to prostatic inflammation, and whether they discriminate prostate cancer (PCa) from inflammatory prostatic conditions. METHODS: Histopathologically diagnosed prostatitis, PCa and benign prostatic hyperplasia patients (n = 93) were enrolled in this study and they were categorized as with and without prostate inflammation. Quantitative RT-PCR was used to analyze the levels of 79-bp and 230-bp fragments in urine and blood samples collected following prostate massage. RESULTS: The urine mtDNA-79 and mtDNA-230 were significantly increased in patients with prostate inflammation compared with those in without inflammation. Here, 79-bp fragment of apoptotic origin was significantly higher level than 230-bp fragment of necrotic origin. Although mtDNA-79 copy number in serum samples was also increased in patients with prostate inflammation, mtDNA-230 was similar in the two groups. Furthermore, mtDNA-79 and mtDNA-230 copy numbers in postprostate massage urine were higher (about 16-fold and 22-fold, respectively) than those from serum samples. ROC analysis showed that, although post-prostate massage urine have relatively higher performance than blood, ability to discriminate cases of both fragments was not better than that of serum total PSA. CONCLUSIONS: Our results demonstrate that shorter cf-mtDNA fragment size in particular, increase in the presence of prostate inflammation in post-prostatic massage urine but both fragments could never improve serum total PSA performance.

BACKGROUND: In the literature, there is not sufficient data on factors affecting the development of complications in patients with penile fracture after early surgical intervention. OBJECTIVES: To investigate the predictors of long-term complications in patients who underwent immediate surgical repair for penile fracture. MATERIALS/METHODS: This clinical study included a total of 31 cases of penile fracture in which surgical treatment was performed within the first 24 h and penile fracture was confirmed during the operation. The patients with and without late complications were compared in terms of parameters such as age, tear size of the tunica albuginea of the penis, bilateral involvement of the corpora cavernosa involvement, urethral injuries, and duration from penile fracture to surgery. RESULTS: The median age of the patients was 42 years (interquartile range: 34-51 years). The median time from penile fracture to surgery was 13 h (8-18 h). The median tear size was 16 mm (11-21 mm). Late complications were seen in 13 (41.9%) patients in the post-operative period. Erectile dysfunction developed in five (16.1%) patients in the post-operative period. There was no statistically significant relationship between age, tear size, time from penile fracture to surgery, and bilateral corporeal involvement in terms of erectile dysfunction development. Painful erections, penile deviations, urethral strictures, tunical scars, and re-fracture were the other late complications. There was a significant relationship between the development of any complication and time from penile fracture to surgery (p = 0.028) and tear size (p = 0.031). In the receiver operating characteristic analysis of complication development, the cut-off value for the time from penile fracture to surgery was 13.5 h. DISCUSSION AND CONCLUSION: We found that the longer time interval between penile fracture and surgery worsened the patient outcomes. In addition, tear size was determined to be a predictor for long-term complications. In our opinion, early treatment of penile fracture can prevent severe complications in these cases.

BACKGROUND: A notable proportion of idiopathic male infertility cases is accompanied by oligozoospermia; and yet, the molecular mechanisms of fertilization problem underlying this defect are still unclear. Epithelial cadherin has been involved in several calcium-dependent cell-to-cell adhesion events; however, its participation in gamete interaction has also not been fully investigated. OBJECTIVE: The aim was to investigate the changes in the expression of E-cadherin, based on the frequency of Single nucleotide polymorphisms in Nuclear Factor Kappa-B 1 and pre-mir-146a in oligospermic men. MATERIALS AND METHODS: In this case-control study, semen and blood samples of 131 oligospermic men as the case group and 239 fertile healthy men as the control group were analyzed. Variants single nucleotide polymorphisms rs28362491 and rs2910164 were performed using polymerase chain reaction-restriction fragment length polymorphism method and E-cadherin expression were determined by immunoprecipitation studies. RESULTS: ins/ins genotype of rs28362491 was determined as a risk factor for idiopathic oligospermia by 1.73 times (p=0.0218), whereas no significant differences were found between the groups concerning pre-mir-146a rs2910164 polymorphism (p=0.2274 in case of GC genotype and p=0.9052 in case of GG genotype). Combined genotype analysis results did not show any notable differences between the multiple comparisons of 28362491-rs2910164 in oligospermic men and control groups. In addition, E-cadherin expression of oligospermic men with ins/ins genotype was significantly lower than patients with del/ins genotype (p=0.0221). E-cadherin expression level was low in oligospermic men with respect to the control group in presence of ins/ins genotype of NFKB1 gene. CONCLUSION: These results suggest that ins allele prevents binding of surface proteins to spermatozoa, leading to a low affinity of sperm-oocyte interaction in oligospermic men.
RESUMEN
We measured the levels of malondialdehyde (MDA), protein carbonyls, glutathione S-transferase (GST) and reducte glutathione (GSH) in seminal plasma and spermatozoa from 95 subjects including 50 infertile patients to evaluate the association between oxidative stress and damage and the components of the anti-oxidant defenses in seminal plasma and spermatozoa of infertile subjects and concentrations of cadmium (Cd) and lead (Pb) in the blood and seminal plasma because of tobacco smoke exposure. The reactive oxygen species (ROS) in spermatozoa were also evaluated by luminol (5-amino-2,3-dihydro-1,4-phthalazinedione)-enhanced chemiluminescence assay. The sperm count, motility, and morphology in the smokers infertile group were found to be lower than those in the fertile male group and nonsmokers infertile group (p < 0.001). Concentrations of Cd, Pb, MDA, protein carbonyls, and ROS levels in the smokers infertile group were significantly higher than those in the fertile male and nonsmokers infertile male groups (p < 0.001). However, GSH levels and GST activities were decreased in the smokers infertile male group than those in the fertile male and nonsmokers infertile male groups (p < 0.001). The results indicate that smoking could affect semen quality and oxidative lipid and protein damage in human spermatozoa. From Pearson correlation analysis, positive correlations were demonstrated between the seminal plasma Cd and seminal plasma protein carbonyls and between seminal plasma Pb and spermatozoa ROS levels in smokers of the subfertile group, while there was a significant positive correlation between blood Cd and ROS levels in smokers of the fertile group. There was also a significant negative correlation of the Cd level of the blood and GSH levels of the sperm and seminal plasma. These findings suggest that cigarette smoking enhances the levels of Cd and Pb in seminal plasma and blood and the extent of oxidative damage associated with a decrease in components of the anti-oxidant defenses in the sperm of infertile males.

The current study assessed the decision-making process before surgery in prostate cancer patients. A structured telephone interview was conducted by an independent third party in 162 consecutive patients who underwent surgery for prostate cancer. Responders revealed that details regarding diagnosis and treatment alternatives were withheld from a significant number of patients. Radiation and active surveillance were presented as alternative options to surgery in 57 (39%) and 20 (14%) of responders, respectively. Twenty-six (18%) patients reported not being informed regarding potential surgical side effects. Patients were not active participants in critical aspects of decision making in 61 (42%) of the cases. Being inadequately informed and more frequent visits to the urologist appeared to make decisions more difficult. Treatment regret was reported by 23 (16%) of the patients who underwent surgery and was more common when the patient was not involved in the decision or was inadequately informed. As such, shared decision making should replace paternalism when managing patients with localized prostate cancer in urologic practice.
RESUMEN
BACKGROUND: Clear cell sarcoma of the kidney (CCSK) in adults is extremely rare. Optimal treatment of adult patients with CCSK remains unclear. CASE PRESENTATION: A 22-year-old man presented with a 2-month history of left flank pain. A color duplex sonography revealed a hypervascular, heterogeneous renal mass. Abdominal and pelvic computerized tomography showed a heterogeneous mass originating from the lower pole of the left kidney and infiltrating to the psoas muscle. Further evaluation including bone scan did not demonstrate any evidence of metastases. A left radical nephrectomy with hilar lymphadenectomy through an intraperitoneal approach with an anterior subcostal incision was performed. The histopathological diagnosis of the mass was a clear cell sarcoma of the kidney. No lymph node metastases were found. Concomitant chemo-radiotherapy was performed. Therapy-related serious side effects were not observed. There was no evidence of local recurrence or metastases during the following twenty-four months after therapy. CONCLUSION: We believe that the combination therapy is efficacious for preventing the local recurrence and distant metastases. Accurate diagnosis is very important and therapy must also include doxorubicin regardless of the disease stage in adult patients with CCSK.

Oxidative stress in the reproductive system is thought to have an effect on the fertilizing ability of sperm. The purpose of this study was to assess the interaction of iron (Fe) and copper (Cu) ions in suspected subfertile and fertile male groups and to find out the relationships of the semen parameters (sperm count, motility, and abnormal morphology), glutathione, malondialdehyde, and reactive oxygen species with these variables. Semen and blood obtained from 60 subfertile men and from 40 fertile volunteers were examined. The sperm count and motility in the subfertile male group were found lower than those in fertile male group (p < 0.001). Cu levels in serum and seminal plasma in the subfertile male group were significantly higher than those in the fertile male group (p < 0.001 and p < 0.05, respectively). There was also a significant increase in the Fe level of seminal plasma in the subfertile male group (p < 0.001). However, there was no significant difference in the Fe level of serum in the subfertile male group. In conclusion, these findings suggest that Cu and Fe might be mediators of the effects of oxidative damage and play an essential role in spermatogenesis and male infertility; the determination of Fe and Cu levels in serum and seminal plasma during infertility investigation is recommended.

After pelvic surgeries such as radical prostatectomy, two major complications--urinary incontinence and erectile dysfunction (ED) may occur. Etiologies for ED are multiple pathologic mediators/systems. Oxidative stress, which is known to be induced after surgical trauma, could be a cause of ED. The purposes of in this study are to investigate the effect of unilateral manipulation/ dissection and resection of the cavernous nerve (neurotomy) to NOS (nitric oxide synthase)-containing nerve fibers and pressure after electro stimulation in rat corpus cavernosum, and to determine whether these procedures would produce oxidative stress within rat cavernous tissue 3 weeks and 6 months after the operation. Male rats were divided into 5 groups. Rats in groups 1 and 2 underwent unilateral cavernous nerve manipulation and sacrificed 3 weeks and 6 months after the operation, respectively. Rats in groups 3 and 4 underwent unilateral neurotomy of a 5-mm. segment of the cavernous nerve, and they were sacrificed 3 weeks and 6 months after nerve ablation, respectively. Group 5 rats were control animals for biochemical analysis. Intracavernous pressure following electro stimulation reduced is significantly 3 weeks after unilateral resection, as compared to that of the manipulated nerve (P < 0.05), and it recovered 6 months after neurotomy. The recovery was also confirmed by NADPH (nicotinamide adenine dinucleotide phosphate) diaphorase staining in neurotomy groups. Lipid peroxidation, which is an indicater of oxidative stress, was determined by measuring thiobarbituric acid reacting substance (TBARS) levels and superoxide dismutase (SOD) activity. These markers indicated that unilateral cavernous nerve manipulation or resection produced oxidative stress within rat corpus cavernosum. Oxidative stress was more prominent 3 weeks after unilateral neurotomy (P < 0.05). Also, compared to the control animal group, oxidative stress was observed three weeks after manipulation of unilateral cavernous nerve (P < 0.05). Resection of the cavernous nerve caused more prominent oxidative stress than in the manipulation group. This study suggested, that unilateral cavernous neurotomy caused a decrease of intra cavernous pressure and NOS fibers in rat corpus cavernosum, and they recovered 6 months after neurotomy. Our data also provided evidence that neurotomy and manipulation of the cavernous nerve caused oxidative stress in rat corpus cavernosum and that oxidative stress was more prominent in the nerve resection group.

Current management strategies of renal angiomyolipomas (AMLs) include observation, embolization and partial or total nephrectomy. Selective arterial embolization is an effective and safe treatment of large angiomyolipomas with low complication rates. Percutaneous drainage was the recommended treatment for renal abscess formation following the embolization. Herein we describe two cases which we performed percutaneous drainage of the liquefaction of entire tumors after embolization. Open surgery was needed for one of the patients who showed recurrence after percutaneous drainage and alcohol irrigation of the cavity, whereas percutaneous drainage was the sufficient treatment for the other patient as recommended.

A case of 70 years old man with a slowly enlarging painful scrotal mass is herein reported. Computed tomography scan of the scrotum showed a homogenous and encapsulated mass, associated with the tunica albuginea. There was no evidence of any metastatic lesion(s). Orchidectomy was performed with high ligation of the spermatic cord. Histopathologic examination revealed a rare case of paratesticular myxofibrosarcoma. Complete surgical resection is the only curative treatment modality in the treatment of these low grade tumors. Adjuvant chemotherapy or radiotherapy are not recommended for paratesticular myxofibrosarcomas.

BACKGROUND: Nuclear factor-kappa B (NF-ð B) activation and its inhibition by NF-ð B inhibitor (Ið B) have been functionally linked to germ cell apoptosis, which may affect human infertility. We hypothesized a possible relationship between the NF-ð B1-94ins/del ATTG (rs28362491) and NF-ð BIA 3'UTR AâG (rs696) polymorphism, which are common polymorphisms and the susceptibility to oligospermia in the context of the sperm apoptosis. METHODS: In order to evaluate this association, we studied the polymorphisms and sperm apoptosis rates of 114 men with idiopathic oligospermia, as well as 130 normospermic men, using PCR-RFLP and TUNEL staining methods, respectively. RESULTS: Univariate analysis revealed that heterozygous ID genotype at the NF-ð B1 -94ins/del ATTG polymorphism is associated with an approximately 2.4-fold reduced risk of oligospermia (P = 0.006, 95% confidence intervall = 1.34 - 4.13). However, the genotype and allele frequencies of NF-ð BIA 3'UTR AâG polymorphism, and the genotype frequencies of all possible rs28362491/rs696 genotype combinations did not show any significant differences between oligospermic and normospermic men. Furthermore, neither polymorphism appeared to affect sperm apoptosis, although the sperm apoptosis index was detected to be significantly higher in the oligospermic patients compared with those in the controls (P < 0.05). CONCLUSION: Our findings suggested that the heterozygosity of rs28362491 in the NF-ð B1 gene may have a protective effect against oligospermia and could modify the susceptibility of oligospermia in a group with idiopathic male infertility in a Turkish population.

PURPOSE: Testicular sperm extraction (TESE) for intracytoplasmic sperm injection (ICSI) was first introduced for the treatment of non-obstructive azoospermia. This study was conducted to detect predictive factors affecting the success of microTESE. MATERIALS AND METHODS: We retrospectively evaluated the results of 191 cases who underwent microTESE. For each patient, the testicular volume, endocrine profile [follicle stimulating hormone (FSH), luteinizing hormone (LH), free testosterone (FT), total testosterone (TT)], serum inhibin B level, karyotype analysis, and Y chromosome microdeletions were recorded, and all data were analyzed to detect any predictors. The receiver operating characteristic curve, two-sample t-test and regression analysis were used for the statistical analysis. RESULTS: The mean age of the patients was 34.4 ± 5.6 years. Sperm retrieval was successful in 104 (54.5%) patients, and there was no sperm in 87 (45.5%). Seven factors including, testicular size, Johnson score, Y chromosome microdeletion, and serum FSH, LH, FT and TT levels were different between the successful and unsuccessful groups. Six patients had Klinefelter syndrome, and ten patients (5.2%) had a Y chromosome microdeletion (5 AZF-c, 1 AZF-b, 2 AZF-bc, 1 AZF-abc, and 1 AZF-ac). The Johnson score, TT level, family history and Y chromosome microdeletions were determined to be independent predictive factors for sperm found. According to the testicular histology, the sperm-found ratios were 36%, 48.6%, and 95.5% in the sertoli cell only syndrome, maturation arrest, and hypospermatogenesis groups, respectively. CONCLUSION: According to our results, the Johnson score, TT level, family history-related infertility, and Y chromosome microdeletions were determined to be independent predictive factors for sperm found.
