Abstract
INTRODUCTION AND OBJECTIVE Previous studies showed that extra blood supply can decrease testicular atrophy following laparoscopic orchiopexy. We evaluated the impact of preserving the gubernacular attachment (which contains blood supply from cremasteric artery and its anastomoses) on atrophy rates following open conventional orchiopexy. STUDY DESIGN This double-blinded randomized trial was implemented from March 2022 to September 2023. Included boys with non-palpable testis, even with examination under anesthesia, underwent diagnostic laparoscopy to evaluate the testis's location and size. Nubbin testes and those with > 2-cm distance from the internal inguinal ring. Participants were assigned into two groups (gubernaculum sparing (GS) and excision (GE)) by permuted block randomization. Overall success was defined as achieving both morphologic success (atrophy <20% of the intraoperative size) and anatomical success (scrotal or high-scrotal locations). Boys were followed at three- and six-month post-surgery via ultrasound. Independent t-test, repeated ANOVA, and Friedman's tests were used where appropriate. RESULTS Of 92 boys (105 UDTs overall), 75 testes (36 in GS, 39 in GE groups) were used in the analysis. The mean age of participants was 25 ± 17 months (range 6-84). The mean testis size of cases intraoperatively was 460 ± 226, 396 ± 166, and 520 ± 258 mm3 among all participants, GS, and GE cases, respectively. Both groups showed a significant decrease in testicular volume on both follow-up checkpoints, but this decrement was significantly higher in the GE group (p < 0.001). The anatomical success rate was significantly higher among GS boys (97.2% versus 82.1%; p = 0.038). The overall success rate was significantly higher for the GS group (61.1% versus 25.6%; p = 0.002). CONCLUSION Although mean testicular volume decreased in both groups, we found superior morphologic and overall success rates among the GS group. The greatest size reduction was noted at the three-month post-surgery compared to the six-month checkpoint. TRIAL REGISTRATION https://irct.ir/trial/58842.

Abstract
OBJECTIVE Management of cryptorchidism is typically recommended within the first 18 months of life to maximize fertility potential. However, there is a paucity of longitudinal postoperative data for Chinese infants. We aim to evaluate the Testicular function change when the procedure is done within the first year of life. METHOD We prospectively enrolled 51 children diagnosed with unilateral inguinal cryptorchidism into the surgical group between January 2021 and January 2022. Orchidopexy was carried out through a single transverse scrotal incision. Assessments of anti-Mullerian hormone (AMH), inhibin B (InhB), testosterone (T) levels, testicular volume and testicular atrophy index (TAI) were conducted at baseline, 6 months, and 1 year following surgery. Concurrently, clinical data from 42 healthy age-matched controls were collected during their routine physical examinations. RESULTS At 6- and 12-months post-surgery, testicular volume increased significantly to 0.98 ± 0.12 mL and 1.01 ± 0.12ml. AMH levels also rose from 76.40 ± 15.77 ng/mL to 81.52 ± 15.32 ng/mL and 87.50 ± 15.36 ng/mL. However, these parameters are significantly lower than age-matched healthy controls (both P < 0.001). InhB levels significantly increased after surgery and even surpassed those of healthy controls after 6 months (both P < 0.001). The TAI was 16.7% and 8.6% at 6- and 12-months following surgery. CONCLUSION Although orchiopexy can improve testicular growth and function, the restoration of testicular function to the level of healthy peers might take longer. To expedite the recovery of testicular function and bring it in line with that of peers, we recommend addressing cryptorchidism at the earliest opportunity.

Abstract
Background: Testicular volume (TV) and testicular atrophy index (TAI) were used to determine criteria for normal, hypotrophic and atrophic undescended testes (UDT). Objectives: This study aimed to determine changes in TV and TAI in patients with different types of UDT. Materials and Methods: 182 boys (aged 0.3-14.0 years) with 212 UDTs were assessed twice 24 months apart. Testes were unilateral (UCT) or bilateral canalicular (BCT) and intra-abdominal (IAT). Results: At the beginning of the observation, the highest TAI was observed in IAT and the lowest in the BCT group (38.1 vs. 12.5%, p < 0.05). After 2 years, the highest TAI was observed in the BCT and IAT groups (20.5 and 19.1%), while the lowest was in the UCT group (12.0%, p < 0.05). At the beginning and after 2 years, the highest TAI was observed in boys aged < 6 years (25.0%, 18.2%) and the lowest in pubertal boys aged 12-14 years (5.9%, 7.3%, p < 0.05). A total of 78.3% of patients at the beginning and 86.8% at the end of the observation had TAI < 30%. Furthermore, 7% of boys at the beginning and 3% at the end of the observation had TAI > 50%. IATs have the highest testicular growth potential (TGP), while BCTs have the lowest (120.0 vs. 28.6%, p < 0.05). The highest TGP was in boys aged < 3 years (100%, p < 0.05) and boys aged 12-14 years (98.1%, p < 0.05), while the lowest was in boys aged 9-10.9 years (19.5%, p < 0.05). Conclusions: We revealed the continuous growth of UDTs until puberty independently of their position. IATs revealed high growth potential.

Abstract
Infertility, affecting one in six couples, is often related to the male partner's congenital and/or environmental conditions or complications postsurgery. This retrospective study examines the link between orchiopexy for undescended testicles (UDT) and testicular torsion (TT) in childhood and adult fertility as assessed through sperm analysis. The study involved the analysis of semen samples from 7743 patients collected at Soroka University Medical Center (Beer Sheva, Israel) between January 2009 and December 2017. Patients were classified into two groups based on sperm concentration: those with concentrations below 5 × 106 sperm per ml (AS group) and those above (MN group). Medical records and surgical histories were reviewed, categorizing orchiopexies by surgical approach. Among 140 individuals who had undergone pediatric surgery, 83 (59.3%) were placed in the MN group and 57 (40.7%) in the AS group. A higher likelihood of being in the MN group was observed in Jewish compared to Arab patients (75.9% vs 24.1%, P = 0.006). In cases of childhood UDT, 45 (78.9%) patients exhibited sperm concentrations below 5 × 106 sperm per ml (P < 0.001), and 66 (76.7%) had undergone unilateral and 18 (20.9%) bilateral orchiopexy. Bilateral orchiopexy was significantly associated with lower sperm concentration, total motility, and progressive motility than unilateral cases (P = 0.014, P = 0.001, and P = 0.031, respectively). Multivariate analysis identified UDT as a weak risk factor for low sperm concentration (odds ratio [OR]: 2.712, P = 0.078), with bilateral UDT further increasing this risk (OR: 6.314, P = 0.012). Jewish ethnicity and TT diagnosis were associated with a reduced risk of sperm concentrations below 5 × 106 sperm per ml. The findings indicate that initial diagnosis, surgical approach, and ethnicity markedly influence male fertility outcomes following pediatric orchiopexy.

Long-term impact of commonly performed operations in pediatric urology on reproductive and sexual health. Ther Adv Urol 2024; 16:17562872241249083. [PMID: 38736900 PMCID: PMC11085008 DOI: 10.1177/17562872241249083] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2023] [Accepted: 03/28/2024] [Indexed: 05/14/2024] Open
Abstract
Introduction Sexual dysfunction is highly prevalent among men of reproductive age. Clinical practice guidelines have been established to assist providers in identification and education of patients who are at increased risk for infertility and sexual dysfunction with certain congenital and acquired urogenital disorders. The authors sought to review the reproductive and sexual health implications of treating common childhood urological conditions with commonly performed surgical procedures. Methods To ensure the inclusion of influential and highly regarded research, we prioritized citations from the most-frequently cited articles on our respective review topics. Our inclusion criteria considered studies with substantial sample sizes and rigorously designed methodologies. Several topics were reviewed, including penile chordee, hypospadias, posterior urethral valves, varicoceles, undescended testicles, and testicular torsion. Results For chordee, surgical plication or corporal grafting may be employed. Erectile function remains unaltered post-surgery, while penile length may decrease after repair, which may be avoided using dermal grafts. Hypospadias repair hinges on severity and availability of the urethral plate. Those who underwent hypospadias repair report decreased penile length, but sexual satisfaction, libido, and semen quality are comparable to controls. Posterior urethral valves are usually treated with valve ablation. While valve ablation and bladder neck incision have not been found to affect ejaculatory function, high degree of concurrent renal dysfunction related to nephrogenic and bladder dysfunction may impact semen parameters and erectile function. Regarding varicocele, earlier management has been associated with better long-term fertility outcomes, and surgical intervention is advisable if there is observable testicular atrophy. Earlier repair of undescended testicle with orchiopexy has been found to improve fertility rates as well as decrease malignancy rates. Unilateral orchiectomy for testicular torsion without the ability for salvage has been shown to have decreased semen parameters but unaffected fertility rates. Conclusion Infertility and sexual dysfunction are multivariable entities, with etiologies both congenital and acquired. At the same time, many common pediatric urology surgeries are performed to correct anatomic pathology that may lead to reproductive dysfunction in adulthood. This review highlights the need for diagnosis and management of pediatric urologic conditions as these conditions may impact long-term sexual function post-operatively.

Abstract
BACKGROUND Cryptorchidism is considered to be one of the most common causes of non-obstructive azoospermia. There are several surgical techniques to retrieve sperm in these patients. Microdissection testicular sperm extraction (m-TESE) is a recent sperm retrieval technique which is considered to be a safe, non-blind, and feasible method. OBJECTIVES This study aimed to investigate sperm retrieval rate (SRR) by the mTESE method in patients who have undergone orchidopexy due to bilateral cryptorchidism. MATERIALS AND METHODS In this retrospective study, 56 ex-cryptorchid patients, who underwent mTESE due to post orchidopexy azoospermia, were included. Patients with hypogonadotropic hypogonadism, Klinefelter syndrome, azoospermia factors (AZF) microdeletion, or chromosomal translocation were excluded from the study. Data were obtained from medical files. RESULTS SRR in this study was 46%. Patients were divided into two groups of negative (n = 30) and positive (n = 26) based on the sperm extraction outcomes. There was no statistically significant difference between two groups regarding the mean age at mTESE, mean age at orchidopexy, testicular size, and serum testosterone concentration. However, testicular location, histological patterns, FSH, and LH level showed to have statistically significant relation with sperm retrieval results. But, according to our logistic regression, none of the included variable in the model including FSH, LH, histopathology, and testis location have a significant effect on the presence of the sperm. DISCUSSION In the present study, SRR was significantly higher in patients with scrotal testis and low level of FSH and LH. CONCLUSIONS Performing mTESE could be recommended in ex-cryptorchid patients with post orchidopexy NOA. Preoperative testicular biopsy seems to be unnecessary while clinical criteria can perfectly define NOA.

Abstract
Infertility is defined as inability to conceive despite regular unprotected sexual intercourse for greater than 1 year. Conditions involving the male partner accounts for the infertility in approximately 50% of cases. The goals of imaging in male infertility are to detect treatable/ reversible causes, imaging for sperm retrieval from testis or epididymis for assisted reproductive techniques like in vitro fertilization or intracytoplasmic sperm injection and to provide appropriate genetic counselling for prevention of occurrence of disease in future offspring. The purpose of this article is to describe imaging features in various causes of male infertility to acquaint radiologists with various imaging appearances of causes of male infertility to avoid missing these pathologies.

Genome-Wide Association Screening Determines Peripheral Players in Male Fertility Maintenance. Int J Mol Sci 2022; 24:ijms24010524.

Abstract
Deciphering the functional relationships of genes resulting from genome-wide screens for polymorphisms that are associated with phenotypic variations can be challenging. However, given the common association with certain phenotypes, a functional link should exist. We have tested this prediction in newly sequenced exomes of altogether 100 men representing different states of fertility. Fertile subjects presented with normal semen parameters and had naturally fathered offspring. In contrast, infertile probands were involuntarily childless and had reduced sperm quantity and quality. Genome-wide association study (GWAS) linked twelve non-synonymous single-nucleotide polymorphisms (SNPs) to fertility variation between both cohorts. The SNPs localized to nine genes for which previous evidence is in line with a role in male fertility maintenance: ANAPC1, CES1, FAM131C, HLA-DRB1, KMT2C, NOMO1, SAA1, SRGAP2, and SUSD2. Most of the SNPs residing in these genes imply amino acid exchanges that should only moderately affect protein functionality. In addition, proteins encoded by genes from present GWAS occupied peripheral positions in a protein-protein interaction network, the backbone of which consisted of genes listed in the Online Mendelian Inheritance in Man (OMIM) database for their implication in male infertility. Suggestive of an indirect impact on male fertility, the genes focused were indeed linked to each other, albeit mediated by other interactants. Thus, the chances of identifying a central player in male infertility by GWAS could be limited in general. Furthermore, the SNPs determined and the genes containing these might prove to have potential as biomarkers in the diagnosis of male fertility.

Abstract
Di-(2-ethylhexyl) phthalate (DEHP) is a kind of environmental endocrine disruptors (EEDs), which has been confirmed to cause serious consequences, such as cryptorchidism. Patients with unilateral cryptorchidism still had oligospermia or infertility even if they received orchidopexy before puberty. Testicular dysgenesis syndrome (TDS) attributes this kind of problems to the abnormal testicular development during the embryonic period, and considers that the environmental exposure factors during pregnancy play a major role. Therefore, for unilateral cryptorchidism, even if one testicle has dropped to scrotum, it may be exposed to these substances and cause damage. Cystic fibrosis transmembrane conduction regulator (CFTR) is very important for the maturation of male reproductive system. Previously, cryptorchidism was thought to cause abnormal expression of heat sensitive protein CFTR in testis, but the expression of CFTR in healthy side (descended side) testis was not clear. In this study, we established SD rats with unilateral cryptorchidism by exposure to DEHP (500 mg/kg/day) during pregnancy, and detected the expression of CFTR and downstream signal NF-κB/COX-2/PGE2 in bilateral testis. Finally, we found that the expression of CFTR and downstream signal NF-κB/COX-2/PGE2 in the undescended testis was significantly abnormal, but the expression of them in the descended testis was also abnormal to some extent. Therefore, we speculate that in addition to high temperature will affect the expression of CFTR, there may be other factors that cause abnormal expression of CFTR induced by DEHP, and lead to abnormal male reproductive function eventually, but the specific mechanism needs to be further studied.

WORLD JOURNAL OF PEDIATRIC SURGERY 2022; 5:e000461. [PMID: 36474738 PMCID: PMC9716856 DOI: 10.1136/wjps-2022-000461] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 09/13/2022] [Indexed: 01/25/2023] Open
Abstract
OBJECTIVE Undescended testes (UDT) is the most common anomaly of the male genitourinary tract. The guidelines suggest that orchidopexy in congenitally UDT should be performed between 6 months and 18 months of age, while in acquired UDT, orchidopexy should be performed before puberty. Delay in treatment increases the risk of cancer and infertility. The main aim of this study was to determine whether we meet international standards in the treatment of UDT. METHODS The present study included all boys who underwent orchidopexy either due to congenital or acquired UDT in 2019 (from January 1 to December 31). For each group, laterality, location, associated anomalies, premature birth and in how many cases ultrasound was applied were determined. Additionally, for each group, the types of surgery, the number of necessary reoperations, and in how many cases atrophy occurred were determined. Finally, ages of referral, of clinical examination, and of orchidopexy were determined. RESULTS During this period, 198 patients with 263 UDT underwent orchidopexy. The median time of orchidopexy for the congenital group was 30 months, while that for the acquired group was 99 months. In the congenital group up to 18 months of age, orchidopexy was performed in 16 (16%) boys, while in the acquired group up to 13 years of age, orchidopexy was performed in 95 (96.94%) boys. CONCLUSION Given the well-known risks of late treatment of UDT, orchidopexy needs to be performed much earlier, especially in the congenital group.

Andrologia 2022; 54:e14532. [PMID: 35882440 DOI: 10.1111/and.14532] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 05/05/2022] [Accepted: 06/06/2022] [Indexed: 11/29/2022] Open
Abstract
Nrf2/Keap1 pathway, which prevents cellular damage against reactive oxygen species production, is disrupted in epididymis following cryptorchidism. In this study, we aimed to use curcumin (Cur) as an activator of Nrf2 to decrease the effects of disruption in this pathway caused by cryptorchidism. In this study, animals were randomly divided into following groups: control, sham-surgery, sham-vehicle, sham-Cur50, sham-Cur100 , cryptorchidism, cryptorchidism-vehicle, cryptorchidism-Cur50 and cryptorchidism-Cur100 . For cryptorchidism induction, the left testicle was removed from the scrotum and sutured to the abdominal wall. Two weeks after surgery, Cur was given orally to animals. After 1 month, sperm parameters and testis histopathology were analysed. The expression of Nrf2, NQO1, HO1, and Keap1 genes was evaluated by real-time polymerase chain reaction. Our data showed that Cur, especially at high doses, could improve sperm parameters and testis histopathology, which were damaged following cryptorchidism induction. The expression of HO1, NQO1, and Nrf2 genes, which had decreased in the cryptorchidism group, showed a significant increase after administration of Cur in a dose-dependent manner. Cur, by inducing the expression of genes involved in the Nrf2/Keap1 pathway, could reduce the adverse effects of cryptorchidism and might be used as adjuvant therapy for decreasing cryptorchidism complications before surgery.

Abstract
In children and adolescents, inguinal and scrotal diseases are relatively common, and imaging is very useful for the diagnosis and differential diagnosis of these diseases. Therefore, it is important to understand the imaging findings of these diseases. In this article, we classify these diseases into small testes, cryptorchidism, patent processus vaginalis, acute scrotum pain, trauma, testicular tumors, and others and describe their characteristic findings.

Abstract
Background: Traditional open orchiopexy is still a standard of treatment for palpable undescended testicles. Recently several authors reported successful results using a laparoscopic approach in the treatment of palpable cryptorchidism. The present systematic review and meta-analysis investigated the utility of laparoscopic orchiopexy for palpable cryptorchidism. Methods: Scientific databases (PubMed, Scopus, Web of Science, and EMBASE) were systematically searched for relevant articles using the following terms: (palpable cryptorchidism or palpable undescended testes) AND (laparoscopic orchiopexy or laparoscopic orchiopexy). The inclusion criteria were all children with unilateral or bilateral palpable undescended testes who underwent laparoscopic orchiopexy (LO) compared to children who underwent conventional open orchiopexy (CO). The main outcomes were the proportion of children requiring redo-orchiopexy and the incidence of postoperative complications. Secondary outcomes were duration and the cost of surgery. Results: The final meta-analysis included five studies involving 705 children; LO, n = 369 (52.3%) and CO, n = 336 (47.7%). The majority of the included patients had unilateral palpable cryptorchidism. No significant differences were found in regard to average age at the time of surgery and follow-up periods between the investigated groups. No statistically significant differences were found in regard to redo-orchiopexy rates (RR = 0.22, 95% CI 0.03–1.88, p = 0.17), early complications (RR = 0.66, 95% CI 0.21–2.08, p = 0.48) and incidence of testicular atrophy (RR = 0.36, 95% CI 0.03–3.88, p = 0.40). No significant differences in the operative duration were observed among the groups. Laparoscopy was associated with higher costs in most of the studies. Conclusion: LO is safe and effective in children with palpable cryptorchidism. The rates of redo-orchiopexy as well as an incidence of early complications and testicular atrophy rates are comparable to CO.

Abstract
Aquaporins (AQPs) are integral transmembrane proteins facilitating transport of water and small solutes, such as glycerol and urea, between cells. In male reproductive tracts, AQPs maintain a milieu conducive for sperm formation, maturation, and storage. The aim of this study was to clarify effects of testicular and epidydimal function on male fertility by investigating localisation and abundances of AQP3 and AQP5 in testes and epididymal segments from dogs with and without unilateral cryptorchidism. Immunohistochemistry results indicated AQP3 and AQP5 have different distribution patterns in reproductive tissues of dogs with and without unilateral cryptorchidism. The AQP3, an aquaglyceroprotein, is present in different germ and Sertoli cells in testis of dogs without cryptorchidism. The AQP5 protein was not detected in germ cells but was present in Sertoli and Leydig cells and in endothelia of blood vessels. In cryptorchid dogs, AQP3 was detected in early-developing germ and Sertoli cells, and AQP5 had a distribution pattern similar to testes of dogs without cryptorchidism. In the epididymis, AQP3 and AQP5 were localised in epithelial cells of dogs with and without cryptorchidism in a cell-specific manner. The AQP3 and AQP5 protein was in larger abundance in the gonads from dogs with and without cryptorchidism. In contrast, AQP3 and AQP5 abundance increased in each segment of the cryptorchid epididymis, likely as a compensatory mechanism associated with the pathologic condition. These results indicate involvement of AQP3 and AQP5 in spermatogenesis and sperm maturation. Results from the present study indicate dogs are a useful for comparative reproductive biology studies.

Abstract
INTRODUCTION The concept of subclinical or compensated male hypogonadism (SHG), characterized by increased gonadotropins and normal testosterone levels is emerging. However, its real clinical significance is still conflicting. The aim of the present study was to summarize and discuss the available evidence related to the possible definition of SHG and the possible advantages of testosterone replacement therapy (TRT). EVIDENCE ACQUISITION A comprehensive systematic Medline, Embase and Cochrane search was performed. Publications from January 1, 1969 up to February 29, 2020 were included. The search was restricted to English-language articles and studies of human participants. EVIDENCE SYNTHESIS Two main clinical forms of SHG can be described. The first identifies young patients who have a positive medical history for testis damage occurring before puberty onset. The second form can occur as a consequence of an age-dependent decline of T. Whereas the former can be the consequence of several congenital or acquired diseases, also possible causes of primary hypogonadism, the real significance of the latter is still debatable. Available evidence indicates that age-related SHG is quite a common phenomenon, occurring in 9.4% of aging men from the general population. Cross-sectional and longitudinal data have documented that it is associated with poor health and can be a sign of forthcoming increased cardiovascular mortality and morbidity. CONCLUSIONS Although available evidence suggests that in aging populations SHG can be considered a particular condition associated with an increased CV risk, it is still unknown if treatment with T can improve any outcomes in these subjects. Hence, further interventional studies are advisable to better understand the characteristics of SHG and the possible advantages of an early TRT.

Abstract
Abstract
STUDY QUESTION
Is there a difference in testicular function in early adulthood between men born with cryptorchidism and men born with normally descended testes?
SUMMARY ANSWER
In men from the general population, a history of cryptorchidism was associated with lower total testis volume and impaired semen quality as well as altered serum levels of reproductive hormones.
WHAT IS KNOWN ALREADY
The association between cryptorchidism and testicular function is well documented in studies based on sub-fertile or infertile men recruited from a clinical setting. However, the association has not previously been investigated in men from the general population, who were unselected regarding fertility status.
STUDY DESIGN, SIZE, DURATION
This is a cross-sectional population-based study of 6376 young Danish men examined from 1996 to 2017.
PARTICIPANTS/MATERIALS, SETTING, METHODS
This study is based on young men from the greater Copenhagen area, Denmark (median age of 19 years) who were unselected regarding fertility status and semen quality. The young men delivered a semen sample, had a blood sample drawn and underwent a physical examination including assessment of testis volume. Participants completed a questionnaire regarding cryptorchidism at birth, current lifestyle and their mother’s pregnancy, after consulting their mother. The differences in markers of testicular function, including testis volume, semen parameters and reproductive hormones between men with and without a history of cryptorchidism were investigated with multiple linear regression analyses.
MAIN RESULTS AND THE ROLE OF CHANCE
The participation rate was 24% for the entire study period. Overall, a history of cryptorchidism was associated with reduced testicular function. In the adjusted models, a history of cryptorchidism was associated with a 3.5 ml lower total testis volume, determined by orchidometer (P < 0.001), 28% lower sperm concentration (95% CI: −37 to −20) and 26% lower inhibin B/FSH ratio (95% CI: −50 to −22) compared to men without a history of cryptorchidism, suggesting a reduced spermatogenetic capacity. Men with a history of cryptorchidism also had a slightly reduced Leydig cell function expressed as a 6% lower testosterone/LH ratio (95% CI: −12 to −0.7). The significant effect sizes and different markers of testicular function pointing in the same direction across the different models based on a large sample size support that the results are not chance findings.
LIMITATIONS, REASONS FOR CAUTION
Information on cryptorchidism at birth and treatment modus was obtained by retrospective self-report, and each participant only delivered one semen sample.
WIDER IMPLICATIONS OF THE FINDINGS
The results suggest that men with a history of cryptorchidism could be at increased risk of experiencing fertility problems. However, among these men there is a wide variation in semen quality and further research is needed in order to identify the subgroup of boys born with cryptorchidism who are at the greatest risk of impaired semen quality when reaching adulthood.
STUDY FUNDING/COMPETING INTEREST(S)
The study received financial support from the Research fund of Rigshospitalet, Copenhagen University Hospital; the European Union (Contract numbers BMH4-CT96-0314, QLK4-CT-1999-01422, QLK4-CT-2002-00603. FP7/2007-2013, DEER Grant agreement no. 212844); the Danish Ministry of Health; the Danish Environmental Protection Agency; A.P. Møller and wife Chastine McKinney Møllers Foundation; and Svend Andersens Foundation. None of the founders had any role in the study design, collection, analysis or interpretation of data, writing of the paper or publication decisions. The authors have nothing to declare.

Abstract
This study is to explore the relationship between vascular endothelial growth factor (VEGF) and pathological changes in cryptorchidism by using murine model of intraperitoneal cryptorchidism with surgical operation. To investigate the relationship between the changes of VEGF expression and heat stress inducing germ cell damage in testicular tissue. Six-week-old ICR male mice were operated to make unilateral cryptorchidism mouse model. Here in our study, a remarkable damaged of germ cells are seen in murine model of unilateral cryptorchidism. And the expression of VEGF was significantly changed in a time dependent way and consistent with the pathological changes of testis, this leading us to conclude that there was a negative correlation between VEGF levels and germ cell damage in unilateral cryptorchidism mouse model. We propose that there is a time dependent decrease of VEGF expression in cryptorchidism and confirm that VEGF is essential in spermatogenesis disorder caused by cryptorchidism and non-obstructive azoospermia.

BACKGROUND The purpose of this study was to summarize our clinical experience with transscrotal transverse incision in the treatment of low and middle cryptorchidism in children. METHODS A total of 796 children with low or middle cryptorchidism participated in this study from March 2012 to May 2018. Transscrotal transverse incision was used to treat low and middle cryptorchidism. Symptoms and signs were followed up at 1 week, 1 month, 3months and every six to 12 months thereafter. RESULTS Testicular descent fixation through transverse scrotal incision was successfully performed in all 796 children. All patients were discharged 1-2 days after the operation. During hospitalization and follow-up, 35 patients had complications, including 7 cases of cryptorchidism recurrence, 5 cases of poor scrotal incision healing, and 23 cases of scrotal haematoma. There were no complications, such as bladder injury, testicular atrophy, inguinal hernia or hydrocele. CONCLUSION Transscrotal transverse incision is a safe and feasible method for the treatment of middle and low cryptorchidism. It has the advantages of less trauma and an aesthetic scar after operation.

Abstract
PURPOSE Laminin 5 and collagen IV are the main compounds of the extracellular matrix of the germinal epithelium. The purpose of this study was to evaluate the concentration of these two markers of fibrosis in the plasma of boys with congenital unilateral cryptorchidism. MATERIALS AND METHODS The study group comprised 43 boys aged 1-3 years with congenital unilateral cryptorchidism. The control group included 54 healthy, age matched boys, admitted for planned hernioplasty. To assess laminin 5 and collagen IV in the plasma of boys with unilateral cryptorchidism, we used a new biosensor with Surface Plasmon Resonance Imaging technique detection. RESULTS The median concentration of laminin 5 and collagen IV in the serum of boys with congenital, unilateral cryptorchidism was higher than in boys with normal scrotal testis. The difference was statistically significant (p < 0.0001). We did not notice a correlation between a higher position of the testicles in the inguinal and/or their condition and levels of laminin 5 and collagen IV in the plasma. CONCLUSION Laminin 5 and collagen IV concentrations in the plasma were higher in patients with congenital unilateral cryptorchidism. We believe that in the future, our results could be compared with fertility level in adulthood.

Abstract
This study aims to determine key genes and pathways that could play important roles in the spermatogenic process of patients with cryptorchidism. The gene expression profile data of GSE25518 was obtained from the Gene Expression Omnibus (GEO) database. Microarray data were analyzed using BRB-Array Tools to identify differentially expressed genes (DEGs) between high azoospermia risk (HAZR) patients and controls. In addition, other analytical methods were deployed, including hierarchical clustering analysis, class comparison between patients with HAZR and the normal control group, gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis, and the construction of a protein–protein interaction (PPI) network. In total, 1015 upregulated genes and 1650 downregulated genes were identified. GO and KEGG analysis revealed enrichment in terms of changes in the endoplasmic reticulum cellular component and the endoplasmic reticulum protein synthetic process in the HAZR group. Furthermore, the arachidonic acid pathway and mTOR pathway were also identified as important pathways, while RICTOR and GPX8 were indentified as key genes involved in the spermatogenic process of patients with cryptorchidism. In present study, we found that changes in the synthesis of endoplasmic reticulum proteins, arachidonic acid and the mTOR pathway are important in the incidence and spermatogenic process of cryptorchidism. GPX8 and RICTOR were also identified as key genes associated with cryptorchidism. Collectively, these data may provide novel clues with which to explore the precise etiology and mechanism underlying cryptorchidism and cryptorchidism-induced human infertility.

Influence of temperature, serum, and gonadotropin supplementation in short- and long-term organotypic culture of human immature testicular tissue. Fertil Steril 2019; 110:1045-1057.e3. [PMID: 30396549 DOI: 10.1016/j.fertnstert.2018.07.018] [Citation(s) in RCA: 43] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Revised: 07/06/2018] [Accepted: 07/18/2018] [Indexed: 12/11/2022]
Abstract
OBJECTIVE To study how temperature, serum, and gonadotropin supplementation affect the organotypic culture of human immature testicular tissue (ITT) in vitro. DESIGN Experimental basic science study. SETTING Reproductive biology laboratory. PATIENT(S) ITT from 4 boys with cancer that had testicular tissue cryopreserved as part of their fertility preservation treatment. INTERVENTION(S) In vitro organotypic culture of ITT, exposed to different temperatures (37°C vs. 34°C), serum (fetal bovine serum [FBS] vs. Knockout Serum Replacement [KOS]), and gonadotropin supplementation (with and without FSH and LH). MAIN OUTCOME MEASURE(S) Characterization of the tissue was performed at days 0, 14, and 70 with the use of reverse-transcription quantitative polymerase chain reaction, terminal deoxynucleotide transferase-mediated dUTP nick-end labeling, histologic analysis by means of hematoxylin-eosin staining, and immunohistochemical staining. Hormonal secretion was determined at days 3, 14, 28, and 70 by means of immunofluorescent assay. RESULT(S) The 37°C conditions showed an accelerated loss of tubular morphology and higher intratubular apoptosis. KOS supplementation triggered the up-regulation of STAR, SOX9, DAZL, DDX4, PLZF, and UTF1, the percentage of SOX9+/androgen receptor (AR)-positive mature Sertoli cells at day 14, and testosterone secretion. Gonadotropin supplementation increased the numbers of both undifferentiated UTF1+ spermatogonia and premeiotic VASA+/SYCP3+ spermatogonia at day 14, and the number of SOX9+ Sertoli cells at day 70. The low SOX9+/AR+ colocalization, the disorganized pattern of ZO-1, and the progressive decrease of antimüllerian hormone secretion indicated inefficient Sertoli cell maturation in vitro. CONCLUSION(S) The 34°C condition in KOS showed the best results for the survival of both spermatogonia and Sertoli cells. FSH/LH supplementation also improved long-term survival of Sertoli cells and the maturation of spermatogonia up to meiotic initiation in short-term culture.

Abstract
BACKGROUND/PURPOSE Inguinal hernia repair and orchidopexy are among the most common operations in boys. The impact on future fertility has not been conclusively defined. This study evaluates sperm quality after previous inguinal surgery. METHODS Spermiograms of men with a desire to conceive children were analyzed. History of previous inguinal surgery (hernia repair, orchidopexy, varicocele ligation) was correlated with sperm quality. Other influential factors (age, BMI, chronic medication, tobacco use) were also tested. RESULTS A total of 333 patients were included. Overall, 12.6% of the subjects had undergone previous inguinal surgery. Of these, 17 (43%) were inguinal hernia repairs, 8 (20%) orchidopexies, and 6 (15%) varicocele ligations, while 9 (22%) could not give an exact history. Abnormal spermiograms were found in 60% (n = 24) of those with previous inguinal surgery versus 48% in controls (p = 0.16). On multivariate analysis, pathologic spermiogram parameters were associated with previous inguinal surgery, orchidopexy, use of chronic medication, and smoking, but NOT with inguinal hernia or varicocele repair alone. CONCLUSIONS Previous inguinal hernia or varicocele repair does not seem to impact negatively on quality of sperm later in life. Orchidopexy, smoking, and use of chronic medication, however, were all associated with pathologic sperm quality parameters. TYPE OF STUDY Prospective comparative study. LEVEL OF EVIDENCE Level II.

Abstract
Moringa oleifera (Moringaceae) is a plant known for having high antioxidant potency, anticancer, hepatoprotective, cardioprotective etc. and many more activities. Besides these, Moringaceae has the potential for attenuating the male sexual dysfunction. Reactive oxygen species/ROS were increased in cryptorchidism and therefore cause infertility by damaging sperm DNA and germ cell apoptosis. There was an increase in heat shock proteins (HSP) in cells, which is affected by heat shock. In the present study, the antioxidant effects of two different doses of M. oleifera Lam Extract (MOLE) on experimentally induced cryptorchid testes of rats was investigated. Forty two male rats (16 days old) were divided into four groups: a normal control group, a cryptorchidism-induced control group and two cryptorchidism-induced groups treated orally with either 400 or 800 mg/kg MOLE for 2 weeks. Our study showed that there were ruptures from interstitial spaces, separation of the germ cells from basal membrane, falling of the germ cells into the lumen, perivascular fibrosis, oedema, increased level of HSP70, apoptosis, malondialdehyde (MDA) and decrease in the level of superoxide dismutase (SOD) after the cryptorchidism. We found that pathological damages, oxidative stress, expression of the HSP70 and germ cell apoptosis were decreased in treated groups with MOLE. In brief, we can say that aqueous extract of M. oleifera reduces the oxidative stress in a unilateral cryptorchidism induced rats, and it might attenuate histopathological damages, HSP expression and germ cell apoptosis.

Abstract
Background Cryptorchidism is the most common developmental abnormality of the male reproductive system. If left untreated, it results with infertility and testicular cancer. According to current evidence, surgery is the mainstay of treatment, and hormonal therapy approaches are still under investigation. For the protection of testicular functions, antioxidants have emerged as novel options. This study aimed to evaluate the protective properties of ozone, a strong antioxidant, on testicular tissue. Material/Methods Thirty-five male Wistar-albino rats, 1-month-old, were used for the study. Groups were formed as follows: 1) control, 2) sham surgery (cryptorchidism), 3) cryptorchidism plus ozone, 4) cryptorchidism plus human chorionic gonadotropin (hCG), and 5) ozone plus hCG. Surgical procedures were performed on all rats except the control group. All rats except the control group were used to create an experimental cryptorchidism model, and left testes of animals were surgically placed into the abdomen. After 1 month of surgery, groups 3, 4, and 5 were given corresponding treatments intraperitoneally for 4 weeks. At the end of the study period, testicular atrophy index (TAI) and testicular sperm motility (TSM) were assessed and biochemical, histopathological, and immunohistochemical tests were performed. Results TAI and TSM were higher in the ozone, hCG, and ozone plus hCG groups than in the sham surgery group (p=0.001). TSM in the ozone group was significantly higher than in the hCG and ozone plus hCG groups. In biochemical analyses, the parameters of oxidative stress (GPx1, MDA, CAT, GSH, SOD) indicated increased oxidative activity in cryptorchidism, which was resolved by applying ozone and hCG (p=0.001). In addition, apoptotic markers, Caspase 3 and bcl-2 were significantly decreased by applying ozone and hCG (p=0.001). Conclusions Results of this study suggest that ozone therapy, either as a single agent or in combination with hCG, is a promising approach for protection of testicular functions.

Abstract
Background: Cryptorchidism is one of the most frequent congenital birth defects in male children and is present in 2-4% of full-term male births. It has several possible health effects including reduced fertility, increased risk for testicular neoplasia, testicular torsion, and psychological consequences. Cryptorchidism is often diagnosed as comorbid; copresent with other diseases. It is also present in clinical picture of several syndromes. However, this field has not been systematically studied. The aim of the present study was to catalog published cases of syndromes which include cryptorchidism in the clinical picture and associated genomic information. Methods: The literature was extracted from Public/Publisher MEDLINE and Web of Science databases, using the keywords including: syndrome, cryptorchidism, undescended testes, loci, and gene. The obtained data was organized in a table according to the previously proposed standardized data format. The results of the study were visually represented using Gephi and karyotype view. Results: Fifty publications had sufficient data for analysis. Literature analysis resulted in 60 genomic loci, associated with 44 syndromes that have cryptorchidism in clinical picture. Genomic loci included 38 protein-coding genes and 22 structural variations containing microdeletions and microduplications. Loci, associated with syndromic cryptorchidism are located on 16 chromosomes. Visualization of retrieved data is presented in a gene-disease network. Conclusions: The study is ongoing and further studies will be needed to develop a complete catalog with the data from upcoming publications. Additional studies will also be needed for revealing of molecular mechanisms associated with syndromic cryptorchidism and revealing complete diseasome network.

Abstract
RNA binding protein polypyrimidine tract binding protein 2 (Ptbp2) as a key alternative splicing regulator for male germ cell development is well established. However, its expression levels and role in cryptorchidism testes tissues has not been explored. Additionally, the molecular mechanism of heat stress impacts the correct proliferation and differentiation of germ cells is unclear. To investigate whether changes in Ptbp2 expression are correlated with heat stress-induced germ cell injury in testicular tissue, we used a murine model of intraperitoneal cryptorchidism with surgical operation. Here we present compelling evidence that germ cells are severely damaged in mice with unilateral cryptorchidism, with non-obstructive azoospermia. And the Ptbp2 and Pgk2 mRNA levels were significantly decreased in parallel, leading us to conclude that the negative correlation between Ptbp2 levels and germ cell injury in unilateral cryptorchidism murine model. We hypothesize that Ptbp2 is susceptible to heat stress and its disruption has resulted in stability decline of germ cell transcripts Pgk2 mRNA, which consequently lead to germ cell injury in cryptorchidism testes. Thus, we confirm that Ptbp2 is an essential factor in heat stress-induced sperm cell injury and non-obstructive azoospermia.
