Abstract
Male infertility can be caused by genetic anomalies, endocrine disorders, inflammation, and exposure to toxic chemicals or gonadotoxic treatments. Therefore, several recent studies have concentrated on the preservation and restoration of fertility to enhance the quality of life for affected individuals. It is currently recommended to biobank the tissue extracted from testicular biopsies to provide a later source of spermatogonial stem cells (SSCs). Another successful approach has been the in vitro production of haploid male germ cells. The capacity of SSCs to transform into sperm, as in testicular tissue transplantation, SSC therapy, and in vitro or ex vivo spermatogenesis, makes them ideal candidates for in vivo fertility restoration. The transplantation of SSCs or testicular tissue to regenerate spermatogenesis and create embryos has been achieved in nonhuman mammal species. Although the outcomes of human trials have yet to be released, this method may soon be approved for clinical use in humans. Furthermore, regenerative medicine techniques that develop tissue or cells on organic or synthetic scaffolds enriched with bioactive molecules have also gained traction. All of these methods are now in different stages of experimentation and clinical trials. However, thanks to rigorous studies on the safety and effectiveness of SSC-based reproductive treatments, some of these techniques may be clinically available in upcoming decades.

In vitro proliferation and differentiation of mouse spermatogonial stem cells in decellularized human placenta matrix. J Biomed Mater Res B Appl Biomater 2024; 112:e35414.

Abstract
Utilizing natural scaffold production derived from extracellular matrix components presents a promising strategy for advancing in vitro spermatogenesis. In this study, we employed decellularized human placental tissue as a scaffold, upon which neonatal mouse spermatogonial cells (SCs) were cultured three-dimensional (3D) configuration. To assess cellular proliferation, we examined the expression of key markers (Id4 and Gfrα1) at both 1 and 14 days into the culture. Our quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis revealed a notable increase in Gfrα1 gene expression, with the 3D culture group exhibiting the highest levels. Furthermore, the relative frequency of Gfrα1-positive cells significantly rose from 38.1% in isolated SCs to 46.13% and 76.93% in the two-dimensional (2D) and 3D culture systems, respectively. Moving forward to days 14 and 35 of the culture period, we evaluated the expression of differentiating markers (Sycp3, acrosin, and Protamine 1). Sycp3 and Prm1 gene expression levels were upregulated in both 2D and 3D cultures, with the 3D group displaying the highest expression. Additionally, acrosin gene expression increased notably within the 3D culture. Notably, at the 35-day mark, the percentage of Prm1-positive cells in the 3D group (36.4%) significantly surpassed that in the 2D group (10.96%). This study suggests that the utilization of placental scaffolds holds significant promise as a bio-scaffold for enhancing mouse in vitro spermatogenesis.

Int J Biol Macromol 2024; 260:129498. [PMID: 38232872 DOI: 10.1016/j.ijbiomac.2024.129498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 01/05/2024] [Accepted: 01/12/2024] [Indexed: 01/19/2024]
Abstract
Testicular tissue culture in vitro is considered an important tool for the study of spermatogenesis and the treatment of male infertility. Although agarose hydrogel is commonly used in testicular tissue culture, the efficiency of spermatogenesis in vitro is limited. In this study, testicular tissues from adult mice were cultured using a gas-liquid interphase method based on agarose (Agarose), gelatin methacryloyl (GelMA), alginate methacryloyl (AlgMA), dextran methacryloyl (DexMA), and mixture GelMA-Agarose, AlgMA-Agarose, and DexMA-Agarose hydrogels, respectively, for 32 days in vitro. The integrity of the seminiferous tubules, the density and proportions of spermatogonia, spermatocytes, Sertoli cells, and testosterone concentrations were quantified and compared between groups. Properties of different hydrogels including compression modulus, Fourier Infrared Spectroscopy (FITR) spectra, pore size, water absorption, and water retention were tested to investigate how biochemical and physical properties of hydrogels affect the results of testicular tissue culture. The results indicate that testicular tissues cultured on AlgMA exhibited the highest seminiferous tubule integrity rate (0.835 ± 0.021), the presence of a high density of spermatocytes (2107.627 ± 232.082/mm2), and a high proportion of SOX9-positive well-preserved seminiferous tubules (0.473 ± 0.047) compared to all remaining experimental groups on day 32. This may be due to the high water content of AlgMA reducing the toxic effect of oxygen on testicular tissue. In the later period of culture, testicular tissues cultured on DexMA, not DexMA-Agarose, produced significantly more testosterone (18.093 ± 3.302 ng/mL) than the other groups, suggesting that DexMA is friendly to Leydig cells. Our study provides a new idea for the optimization of the gas-liquid interphase method for achieving in vitro spermatogenesis, facilitating the future achievement of efficient in vitro spermatogenesis in more species, including humans.

Abstract
This review aims to explore advanced reproductive technologies for male fertility preservation, underscoring the essential role that animal models have played in shaping these techniques through historical contexts and into modern applications. Rising infertility concerns have become more prevalent in human populations recently. The surge in male fertility issues has prompted advanced reproductive technologies, with animal models playing a pivotal role in their evolution. Historically, animal models have aided our understanding in the field, from early reproductive basic research to developing techniques like artificial insemination, multiple ovulation, and in vitro fertilization. The contemporary landscape of male fertility preservation encompasses techniques such as sperm cryopreservation, testicular sperm extraction, and intracytoplasmic sperm injection, among others. The relevance of animal models will undoubtedly bridge the gap between traditional methods and revolutionary next-generation reproductive techniques, fortifying our collective efforts in enhancing male fertility preservation strategies. While we possess extensive knowledge about spermatogenesis and its regulation, largely thanks to insights from animal models that paved the way for human infertility treatments, a pressing need remains to further understand specific infertility issues unique to humans. The primary aim of this review is to provide a comprehensive analysis of how animal models have influenced the development and refinement of advanced reproductive technologies for male fertility preservation, and to assess their future potential in bridging the gap between current practices and cutting-edge fertility techniques, particularly in addressing unique human male factor infertility.

Abstract
In vitro production of sperm is a desirable idea for fertility preservation in azoospermic men and prepubertal boys suffering from cancer. In this study, a biocompatible porous scaffold based on a triad mixture of silk fibroin (SF), alginate (Alg), and laminin (LM) is developed to facilitate the differentiation of mouse spermatogonia stem cells (SSCs). Following SF extraction, the content is analyzed by SDS-PAGE and stable porous 3D scaffolds are successfully prepared by merely Alg, SF, and a combination of Alg-SF, or Alg-SF-LM through freeze-drying. Then, the biomimetic scaffolds are characterized regarding the structural and biological properties, water absorption capacity, biocompatibility, biodegradability, and mechanical behavior. Neonatal mice testicular cells are seeded on three-dimensional scaffolds and their differentiation efficiency is evaluated using real-time PCR, flow cytometry, immunohistochemistry. Blend matrices showed uniform porous microstructures with interconnected networks, which maintained long-term stability and mechanical properties better than homogenous structures. Molecular analysis of the cells after 21 days of culture showed that the expression of differentiation-related proteins in cells that are developed in composite scaffolds is significantly higher than in other groups. The application of a composite system can lead to the differentiation of SSCs, paving the way for a novel infertility treatment landscape in the future.

Morphometric and immunohistochemical analysis as a method to identify undifferentiated spermatogonial cells in adult subjects with Klinefelter syndrome: a cohort study. Fertil Steril 2022; 118:864-873. [PMID: 36116982 DOI: 10.1016/j.fertnstert.2022.07.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 07/08/2022] [Accepted: 07/14/2022] [Indexed: 01/13/2023]
Abstract
OBJECTIVE To study the prevalence of spermatogonia in adult subjects with Klinefelter syndrome (KS) using MAGE-A4 and UCHL1 (PGP9.5) immunohistochemistry as markers for undifferentiated spermatogonial cells. We aimed to compare this method to the gold standard of hematoxylin and eosin (H & E) staining with histologic analysis in the largest reported cohort of adult subjects with KS. DESIGN A retrospective cohort study. SETTING Infertility Clinic and Institute for Regenerative Medicine. PATIENT(S) This study consisted of 79 adult subjects with KS and 12 adult control subjects. INTERVENTION(S) The subjects with KS (n = 79) underwent bilateral testicular biopsy in an initial effort to recover spermatozoa for in vitro fertilization and intracytoplasmic sperm injection. The institutional review board approved the use of a portion of the archived diagnostic pathology paraffin blocks for the study. The samples were superimposed onto microscopic slides and labeled with the PGP9.5 and MAGE-A4 antibodies. Subjects (n = 12) who had previously consented to be organ donors via the National Disease Research Interchange were selected as controls. Dedicated genitourinary pathologists examined the H & E-, PGP9.5-, and MAGE-A4-stained tissue for presence of undifferentiated spermatogonia and spermatozoa with the use of a virtual microscopy software. MAIN OUTCOME MEASURE(S) The primary outcome was the presence of MAGE-A4-positive or UCHL1-positive tubules that indicate undifferentiated spermatogonia. Supportive outcomes include assessing the biopsy specimen for the following: total surface area; total seminiferous tubule surface area; total interstitium surface area; the total number of seminiferous tubules; and MAGE-A4- negative or UCHL1-negative tubules. Additionally, clinical information, such as age, karyotype, height, weight, mean testicle size, and hormonal panel (luteinizing hormone, follicle-stimulating hormone, and testosterone), was obtained and used in a single and multivariable analysis with linear regression to determine predictive factors for the number of UCHL1-positive tubules. RESULT(S) The mean age of the subjects in the KS group was 32.9 ± 0.7 years (range, 16-48). UCHL1 (PGP9.5) and MAGE-A4 staining showed that 74.7% (n = 59) and 40.5% (n = 32) of the subjects with KS, respectively, were positive for undifferentiated spermatogonia compared with 100% (n = 12) of the control subjects who were positive for both the markers. Hematoxylin and eosin with microscopic analysis showed that only 10.1% (n = 8) of the subjects were positive for spermatogonia. The mean number of positive tubules per subject with KS was 11.8 ± 1.8 for UCHL1 and 3.7 ± 1.0 for MAGE-A4. Secondary analysis showed 7 (8.9%) adult subjects with KS as positive for spermatozoa on biopsy. The population having negative testicular sperm extraction results (n = 72) showed a spermatogonia-positive rate of 1.4%, (n = 1), 72.2% (n = 52), and 34.7% (n = 25) using H & E, UCHL1, and MAGE-A4, respectively. Further analysis showed that 54 (75.0%) subjects were either positive for UCHL1 or MAGE-A4. Twenty (27.8%) subjects were positive for both UCHL1 and MAGE-A4. Multivariate analysis with linear regression showed no significant correlation between clinical variables and the number of UCHL1-positive tubules found on biopsy specimens. CONCLUSION(S) We report a cohort of adult subjects with KS undergoing analysis for the presence of undifferentiated spermatogonia. UCHL1 and MAGE-A4 immunostaining appear to be an effective way of identifying undifferentiated spermatogonia in testicular biopsy specimens of subjects with KS. Despite observing deterioration in the testicular architecture, many patients remain positive for undifferentiated spermatogonia, which could be harvested and potentially used for infertility therapy in a patient with KS who is azoospermic and has negative testicular sperm extraction results.

Abstract
N-methyl-d-aspartate (NMDA) modulates the spermatogenesis process through stimulating the steroid hormone biosynthesis. The aim of this study was to evaluate the effects of NMDA receptors agonists (d-Serine) and antagonists (MK801) on spermatogonia differentiation on decellularization testicular matrix (DTM) hydrogel scaffold. Four treatment groups were planned: 2D + D-Serine, 3D + D-Serine, 2D + MK801, and 3D + MK801. Results showed that cell viability was significantly decreased after 48 h in the 3D + D-Serine group and after 24 and 48 h in the 3D + MK801 group compared to the controls. The spermatogonia proliferation after two, four, and eight weeks was significantly increased in the 3D + D-Serine culture, while it was significantly reduced in the 2D + MK801 and 3D + MK801 groups after four and eight weeks. Real-time PCR results demonstrated that pre-meiotic gene (Plzf) expression was significantly increased only in the 3D + D-Serine culture compared to the control groups after four weeks of culture. The meiotic gene (Sycp3) expression was significantly increased in the 2D + D-Serine and 3D + D-Serine compared to the 2D controls after four and eight weeks. The post-meiotic gene (Tnp1) level in the 3D + D-Serine was significantly higher than the other groups. Flow-cytometry results indicated that the protein expression of Plzf (after four and eight weeks), Sycp3 (after eight weeks), and Tnp1 (after eight weeks) in the d-Serine-treated groups was significantly increased compared with the 2D control groups. There were not any significant changes in the gene expression of spermatogenic-related markers in MK801 culture media. However, a significant decrease in the protein levels of Plzf after eight weeks and Sycp3 after four and eight weeks was observed. In conclusion, the addition of NMDARs agonists (d-Serine) could be used to regulate the differentiation of spermatogonia in the 3D culture system.

Abstract
Background: Retinoic acid plays an essential role in testicular development and functions, especially spermatogenesis. We have reviewed the role of retinoic acid from basic (molecular) to clinical application. Methods: A search was conducted in the online database including PubMed, Google Scholar, and Scopus for English studies published in the last eight years about this issue. We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in assessing the studies we are going to investigate. Results: Studies indicated that retinoic acid plays an essential role during pluripotent stem cell migration and lineage commitment, cell differentiation, apoptosis, stem cell number regulation, and maturation arrest in spermatogenic cells. Retinoic acid can also affect related protein expression and signaling pathways at different stages of spermatogenesis. Four studies have applied retinoic acid to humans, all of them in the single-arm observational study. The results look promising but need further research with more controlled study methods, randomization, and large samples. Conclusions: This current systematic review emphasizes a novel retinoic acid mechanism that has not been well described in the literature previously on its functions during the first seven days of spermatogenesis, leading to new directions or explanations of male infertility cause and treatments as a part of reproductive health care.

Abstract
Infertility has become the third most common disease threatening human health, immediately after tumors and cardiovascular diseases. Male infertility is primarily caused by spermatogenesis disorders which may be classified as either genetic or non-genetic. For part of non-genetic disorders, in vitro spermatogenesis can be induced by adjusting the microenvironment of the testis culture. Establishing the in vitro spermatogenic induction system helps to clarify the critical molecular mechanisms in spermatogonia self-renewal, spermatocyte meiosis, and sperm formation during spermatogenesis. In this review, we summarize recent advances in the field of in vitro sperm cells induction. Therefore, we hope to provide ideas and solutions for the clinical treatment of male infertility.

Abstract
This research presents a novel Testis-on-a Chip- platform. Testicular cells are enzymatically isolated from the seminiferous tubules of sexually immature mice, seeded in a methylcellulose gel and cultured in a microfluidic chip. The unique design sandwiches the soft methylcellulose between stiffer agar support gels. The cells develop into organoids continuing to proliferate and differentiate. After seven weeks of culture the cells have over 95% viability. Confocal microscopy of the developed organoids reveals a structure containing the various stages of spermatogenesis up to and including meiosis II: premeiotic, meiotic and post-meiotic germ cells. The organoid structure also contains the supporting Sertoli and peritubular cells. The responsiveness of the system to the addition of testosterone and retinoic acid to the culture medium during the experiment are also investigated. As a benchmark, the Testis-on-a-Chip is compared to a conventional three-dimensional methylcellulose cell culture in a well plate. Analysis via FACS (Fluorescence-activated cell sorting) shows more haploid cells in the chip as compared to the plates. Immunofluorescence staining after seven weeks of culture shows more differentiated cells in the chip as compared to the well plate. This demonstrates the feasibility of our platform as well as its advantages. This research opens new horizons for the study and realization of spermatogenesis in-vitro. It can also enable the implementation of microfluidic technologies in future therapeutic strategies for pre pubertal male fertility preservation and adults with maturation arrest. Lastly, it can serve as a platform for drug and toxin testing.

Abstract
Klinefelter syndrome (KS) is characterized by a masculine phenotype, supernumerary sex chromosomes (usually XXY), and spermatogonial stem cell (SSC) loss in their early life. Affecting 1 out of every 650 males born, KS is the most common genetic cause of male infertility, and new fertility preservation strategies are critically important for these patients. In this study, testes from 41, XXY prepubertal (3-day-old) mice were frozen-thawed. Isolated testicular cells were cultured and characterized by qPCR, digital PCR, and flow cytometry analyses. We demonstrated that SSCs survived and were able to be propagated with testicular somatic cells in culture for up to 120 days. DNA fluorescent in situ hybridization (FISH) showed the presence of XXY spermatogonia at the beginning of the culture and a variety of propagated XY, XX, and XXY spermatogonia at the end of the culture. These data provide the first evidence that an extra sex chromosome was lost during innate SSC culture, a crucial finding in treating KS patients for preserving and propagating SSCs for future sperm production, either in vitro or in vivo. This in vitro propagation system can be translated to clinical fertility preservation for KS patients.

Abstract
Demystifying the mechanisms that underlie germline development and gamete production is critical for expanding advanced therapies for infertile couples who cannot benefit from current infertility treatments. However, the low number of germ cells, particularly in the early stages of development, represents a serious challenge in obtaining sufficient materials required for research purposes. In this regard, pluripotent stem cells (PSCs) have provided an opportunity for producing an unlimited source of germ cells in vitro. Achieving this ambition is highly dependent on accurate stem cell niche reconstitution which is achievable through applying advanced cell engineering approaches. Recently, hydrogel microparticles (HMPs), as either microcarriers or microcapsules, have shown promising potential in providing an excellent 3-dimensional (3D) biomimetic microenvironment alongside the systematic bioactive agent delivery. In this review, recent studies of utilizing various HMP-based cell engineering strategies for appropriate niche reconstitution and efficient in vitro differentiation are highlighted with a special focus on the capabilities of droplet-based microfluidic (DBM) technology. We believe that a deep understanding of the current limitations and potentials of the DBM systems in integration with stem cell biology provides a bright future for germ cell research.

Abstract
Germ cell production from stem cells allows for studying the mechanisms involved in gamete development with the aim of helping infertile couples with the generation of healthy gametes. In this context, improving the protocols for in-vitro germ cell induction from stem cells is very important. Recently, SB4 small molecule has been introduced as a potent agonist for bone morphogenic protein 4 (BMP4). Herein, we investigated whether BMP4, is replaceable by SB4 for having affordable protocol for in vitro germ cell differentiation. We demonstrated that SB4 can induce Blimp1 (as the first gene induced germ line differentiation) expression significantly but at a lower level compared to BMP4. However, Tfap2c (a putative downstream target of Blimp1 during germ cell differentiation) expression level in SB4-induced aggregates was significantly higher than in BMP4-induced aggregates. Moreover, co-presence of both BMP4 and SB4 could increase the expression level of Prdm14, Nnose3 and Stella (Dppa3), and thereby improve establishment of the germ cell fate during in-vitro differentiation of embryonic stem cells. In summary, our data suggest that SB4 could improve germ line gene expression pattern induced by BMP4 during embryonic stem cells in-vitro differentiation.

Abstract
In vitro spermatogenesis can be performed for marine medaka (Oryzias dancena) via whole testis organ cultures, but spermatogenesis could only be maintained during the early phase of culturing, suggesting that the culture conditions can be further optimized. To improve the culture conditions, we examined the effects of culture temperature, basal media, and medium supplements on spermatogonial proliferation levels during whole testis organ culturing by BrdU incorporation assays. Our results show that a 30°C culture temperature negatively affected spermatogonial proliferation compared to 26°C and 28°C and that the use of Dulbecco's Modified Eagle Medium and Minimum Essential Medium α (α-MEM) was more effective for spermatogonial proliferation than the use of Leibovitz's L-15 Medium (L15). When fetal bovine serum (FBS) was replaced with KnockOut Serum Replacement (KSR), a significantly positive effect was observed for the maintenance of spermatogonial proliferation. However, supplementation of the medium with 17α, 20β-dihydroxy-4-pregnen-3-one did not show any significant effect. Gene expression analyses of four genes, including Nanos2, SCP3, AMH, and StAR, indicated that the optimized culture conditions consisting of α-MEM and KSR had the most positive influence on the maintenance of spermatogonial proliferation levels in whole testis organ cultures compared to the original culture conditions consisting of L15 and FBS by maintaining the function of Sertoli and Leydig cells. The results from this study will provide useful information for the study of in vitro spermatogenesis in fish.

Abstract
Retrieving spermatozoa from the testicles has been a great hope for patients with non-obstructive azoospermia (NOA), but relevant methods have not yet been developed to the level necessary to provide resolutions for all cases of NOA. Although performing testicular sperm extraction under microscopic magnification has increased sperm retrieval rates, in vitro selection and processing of quality sperm plays an essential role in the success of in vitro fertilization. Moreover, sperm cryopreservation is widely used in assisted reproductive technologies, whether for therapeutic purposes or for future fertility preservation. In recent years, there have been new developments using advanced technologies to freeze and preserve even very small numbers of sperm for which conventional techniques are inadequate. The present review provides an up-to-date summary of current strategies for maximizing sperm recovery from surgically obtained testicular samples and, as an extension, optimization of in vitro sperm processing techniques in the management of NOA.

Abstract
Aggressive chemotherapy treatment may lead to male infertility. Prepubertal boys do not produce sperm at this age, however, they have spermatogonial stem cells in their testes. Here, we examined the effect of intraperitoneal injection of cyclophosphamide (CP) on the capacity of immature mice (IM) to develop spermatogenesis in vivo and in vitro [using methylcellulose culture system (MCS)]. Our results show a significant decrease in testicular weight, total number of testicular cells, and the number of Sertoli, peritubular, premeiotic, and meiotic/post-meiotic cells, but an increase in the percentages of damaged seminiferous tubules in CP-treated IM compared to control. The functionality of Sertoli cells was significantly affected. The addition of testosterone to isolated cells from seminiferous tubules of CP-treated IM significantly increased the percentages of premeiotic (CD9-positive cells) and meiotic/post-meiotic cells (ACROSIN-positive cells) developed in MCS compared to control. The addition of FSH did not affect developed cells in MCS compared to control, but in combination with testosterone, it significantly decreased the percentages of CD9-positive cells and ACROSIN-positive cells. The addition of IL-1 did not affect developed cells in MCS compared to control, but in combination with testosterone, it significantly increased the percentages of VASA-positive cells and BOULE-positive cells compared to IL-1 or testosterone. Addition of TNF significantly increased only CD9-positive cells in MCS compared to control, but in combination with testosterone, it significantly decreased ACROSIN-positive cells compared to testosterone. Our results show a significant impairment of spermatogenesis in the testes of CP-treated IM, and that spermatogonial cells from these mice proliferate and differentiate to meiotic/post-meiotic cells under in vitro culture conditions.

Abstract
In modern life, several factors such as genetics, exposure to toxins, and aging have resulted in significant levels of male infertility, estimated to be approximately 18% worldwide. In response, substantial progress has been made to improve in vitro fertilization treatments (e.g. microsurgical testicular sperm extraction (m-TESE), intra-cytoplasmic sperm injection (ICSI), and round spermatid injection (ROSI)). Mimicking the structure of testicular natural extracellular matrices (ECM) outside of the body is one clear route toward complete in vitro spermatogenesis and male fertility preservation. Here, a new wave of technological innovations is underway applying regenerative medicine strategies to cell-tissue culture on natural or synthetic scaffolds supplemented with bioactive factors. The emergence of advanced bioengineered systems suggests new hope for male fertility preservation through development of functional male germ cells. To date, few studies aimed at in vitro spermatogenesis have resulted in relevant numbers of mature gametes. However, a substantial body of knowledge on conditions that are required to maintain and mature male germ cells in vitro is now in place. This review focuses on advanced bioengineering methods such as microfluidic systems, bio-fabricated scaffolds, and 3D organ culture applied to the germline for fertility preservation through in vitro spermatogenesis.

Abstract
The main aim of current pediatric male fertility preservation programs is storing spermatogonia stem cell (SSC) prior to starting cancer treatment. From July 1st, 2014 to May 1st, 2020; 170 patients have been recruited in Wake Forest Testicular Tissue Banking Program. The existence of multiple testis biopsies in different time points and detailed histological analyses of a unique cancer patient, provided an educational opportunity to investigate testis condition in different phases of cancer management. A pediatric male cancer patient with B-cell acute lymphoblastic leukemia (ALL) had multiple testicular leukemia recurrences and went through several testicular biopsies, to identify leukemic infiltration as well as considering fertility preservation. Infiltration of leukemia cells into both testes was identified. Neither elongated spermatid nor sperm were detected, but germ cells including SSC, spermatocyte and round spermatid could be identified in the stored tissue even after initial cancer treatment. Different germ cells were identified by hematoxylin and eosin (H&E) staining and specific immunohistochemical (IHC) markers including PGP9.5/UCHL1 or MAGE-A4 (spermatogonia), SYCP3 (spermatocyte) and PRM1 (round spermatid). This emphasizes the importance of offering testicular biopsy to pediatric cancer patients at risk of infertility regardless to the stage of cancer treatment, although earlier biopsy is preferred. Promising research on in vitro spermatogenesis and auto-transplantation support the practice of SSC preservation. In addition, finding and storing round spermatids isolated from testicular biopsy provides a currently available option of round spermatid injection (ROSI). Given the complexity of managing cancer while considering fertility preservation, a multidisciplinary collaboration is important to achieve optimal overall outcomes.

Abstract
Cryopreservation of immature-testicular-tissue (ITT) prior to gonadotoxic treatment, while experimental, is the only recommended option for fertility preservation in prepubertal boys. The handling and manipulation of ITT before cryopreservation could influence the functionality of cells during fertility restoration, which this study explored by evaluating cellular niche and quality of mouse ITT subjected to various temperatures and time durations in vitro. ITT from 6-day-old mice were handled at ultraprofound-hypothermic, profound-hypothermic, and mild-warm-ischemic temperatures for varying time periods prior to 14-day organotypic culture. Viability, functionality, synaptonemal complex and chromatin remodeling markers were assessed. Results have shown that cell viability, testosterone level, and in vitro proliferation ability did not change when ITT were held at ultraprofound-hypothermic-temperature up to 24 h, whereas cell viability was significantly reduced (P < 0.01), when held at profound-hypothermic-temperature for 24 h before culture. Further, cell viability and testosterone levels in cultured cells from profound-hypothermic group were comparable to corresponding ultraprofound-hypothermic group but with moderate reduction in postmeiotic cells (P < 0.01). In conclusion, holding ITT at ultraprofound-hypothermic-temperature is most suitable for organotypic culture, whereas short-term exposure at profound-hypothermic-temperature may compromise postmeiotic germ cell yield post in vitro culture. This data, albeit in mouse model, will have immense value in human prepubertal fertility restoration research.

[PMID: 32992121 DOI: 10.1016/j.acthis.2020.151623] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 08/19/2020] [Accepted: 08/20/2020] [Indexed: 12/19/2022]
Abstract
Improvement of in vitro culture methods of Spermatogonial Stem Cells (SSCs) is known to be an effective procedure for further study of the process of spermatogenesis and can offer effective therapeutic modality for male infertility. Tissue decellularization by providing natural 3D and extracellular matrix (ECM) conditions for cell growth can be an alternative procedure to enhance in vitro culture conditions. In the present study, the testicular tissues were taken from brain death donors. After enzymatic digestion, the tissue cells were isolated and cultured for four weeks. Then the identity of the SSCs was confirmed using anti-GFRα1 and anti-PLZF antibodies via immunocytochemistry (ICC). The differentiation capacity of SSCs were evaluated by culture of them on a layer of decellularized testicular matrix (DTM) prepared from sheep testis, as well as under two-dimensional (2D) culture with differentiation medium. After four and six weeks of the initiation of differentiation culture, the pre-meiotic, meiotic and post- meiotic genes at the mRNA and protein levels was examined via qPCR and ICC methods, respectively. The results showed that pre-meiotic, meiotic and post-meiotic genes expressions were significantly higher in the cells cultured in DTM substrate (P ≤ 0.01).The present study indicated that, the natural structure of ECM prepare the suitable conditions for further study of the spermatogenesis process in the in vitro and contributes to the maintenance and treatment of male infertility.

Abstract
BACKGROUND Oncological procedures have irreversible side effects on germ cells for childhood cancer survival boys. In vitro culture of prepubertal testicular tissue has been proposed to restore fertility; however, recent data on animal models showed that meiotic and post-meiotic progression was impaired. OBJECTIVES As potential key inducers of the mitosis-meiosis switch, type 2 cannabinoid receptor (CB2 ) has been proposed to play a central role in the meiotic entry of male germ cells. Herein, the in vitro first spermatogenesis wave in mice was used to understand the impact of CB2 activation on the differentiation of spermatogonia until elongated spermatids. MATERIALS AND METHODS A first set of cultured testicular explants of 6.5 days post-partum (dpp) mice was performed to assess the impact of a range of JWH133 supplementation (10 nm, 100 nm, 1 µm, 10 µm). Then, the progressive development of germ cells at key timepoints of spermatogenesis was evaluated throughout (i) in vitro culture (day 2 [D2], D3, D6, D10, D18, and D30) coupled with (ii) in vivo counterparts (8.5, 9.5, 12.5, 16.5, 24.5, and 36.5 dpp). RESULTS CB2 was detected at the plasma membrane of cells, and a successful completion of spermatogenesis was obtained in vitro. One day after the activation of CB2 by 1 μm of the agonist JWH133, percentage of zygotene spermatocyte I increased. CONCLUSION After 30 days of culture, (i) an enrichment of haploid germ cells detected by flow cytometry, (ii) a reduced necrotic area, and (iii) an increase in the density of post-meiotic germ cells were observed. We showed that the activation of CB2 improves in vitro entry into meiosis and differentiation of spermatogonia, mimicking physiological meiotic transition.

Age-related presence of spermatogonia in patients with Klinefelter syndrome: a systematic review and meta-analysis. Hum Reprod Update 2020; 26:58-72. [PMID: 31822886 DOI: 10.1093/humupd/dmz038] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 09/15/2019] [Accepted: 09/30/2019] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Klinefelter syndrome (KS) has been defined by sex chromosome aneuploidies (classically 47, XXY) in the male patient. The peripubertal timeframe in KS patients has been associated with the initiation of progressive testicular fibrosis, loss of spermatogonial stem cells (SSC), hypogonadism and impaired fertility. Less than half of KS patients are positive for spermatozoa in the ejaculate or testis via semen analysis or testicular sperm extraction, respectively. However, the chance of finding spermatogonia including a sub-population of SSCs in KS testes has not been well defined. Given the recent demonstration of successful cell culture for mouse and human SSCs, it could be feasible to isolate and propagate SSCs and transplant the cells back to the patient or to differentiate them in vitro to haploid cells. OBJECTIVE AND RATIONALE The main objective of this study was to meta-analyse the currently available data from KS patients to identify the prevalence of KS patients with spermatogonia on testicular biopsy across four age groups (year): fetal/infantile (age ≤ 1), prepubertal (age 1 ≤ x ≤ 10), peripubertal/adolescent (age 10 < x < 18) and adult (age ≥ 18) ages. Additionally, the association of endocrine parameters with presence or absence of spermatogonia was tested to obtain a more powered analysis of whether FSH, LH, testosterone and inhibin B can serve as predictive markers for successful spermatogonia retrieval. SEARCH METHODS A thorough Medline/PubMed search was conducted using the following search terms: 'Klinefelter, germ cells, spermatogenesis and spermatogonia', yielding results from 1 October 1965 to 3 February 2019. Relevant articles were added from the bibliographies of selected articles. Exclusion criteria included non-English language, abstracts only, non-human data and review papers. OUTCOMES A total of 751 papers were identified with independent review returning 36 papers with relevant information for meta-analysis on 386 patients. For the most part, articles were case reports, case-controlled series and cohort studies (level IV-VI evidence). Spermatogonial cells were present in all of the fetal/infantile and 83% of the prepubertal patients' testes, and in 42.7% and 48.5% of the peripubertal and adult groups, respectively were positive for spermatogonia. Additionally, 26 of the 56 (46.4%) peripubertal/adolescent and 37 of the 152 (24.3%) adult patients negative for spermatozoa were positive for spermatogonia (P < 0.05). In peripubertal/adolescent patients, the mean ± SEM level for FSH was 12.88 ± 3.13 IU/L for spermatogonia positive patients and 30.42 ± 4.05 IU/L for spermatogonia negative patients (P = 0.001); the mean ± SEM level LH levels were 4.36 ± 1.31 and 11.43 ± 1.68 IU/L for spermatogonia positive and negative, respectively (P < 0.01); the mean ± SEM level for testosterone levels were 5.04 ± 1.37 and 9.05 ± 0.94 nmol/L (equal to 145 ± 40 and 261 ± 27 and ng/dl) for the spermatogonia positive and negative groups, respectively (P < 0.05), while the difference in means for inhibin B was not statistically significant (P > 0.05). A similar analysis in the adult group showed the FSH levels in spermatogonia positive and negative patients to be 25.77 ± 2.78 and 36.12 ± 2.90 IU/L, respectively (mean ± SEM level, P < 0.05). All other hormone measurements were not statistically significantly different between groups. WIDER IMPLICATIONS While azoospermia is a common finding in the KS patient population, many patients are positive for spermatogonia. Recent advances in SSC in vitro propagation, transplantation and differentiation open new avenues for these patients for fertility preservation. This would offer a new subset of KS patients a chance of biological paternity. Data surrounding the hormonal profiles of KS patients and their relation to fertility should be interpreted with caution as a paucity of adequately powered data exists. Future work is needed to clarify the utility of FSH, LH, testosterone and inhibin B as biomarkers for successful retrieval of spermatogonia.

Abstract
Male fertility preservation is required when treatment with an aggressive chemo-/-radiotherapy, which may lead to irreversible sterility. Due to new and efficient protocols of cancer treatments, surviving rates are more than 80%. Thus, these patients are looking forward to family life and fathering their own biological children after treatments. Whereas adult men can cryopreserve their sperm for future use in assistance reproductive technologies (ART), this is not an option in prepubertal boys who cannot produce sperm at this age. In this review, we summarize the different technologies for male fertility preservation with emphasize on prepubertal, which have already been examined and/or demonstrated in vivo and/or in vitro using animal models and, in some cases, using human tissues. We discuss the limitation of these technologies for use in human fertility preservation. This update review can assist physicians and patients who are scheduled for aggressive chemo-/radiotherapy, specifically prepubertal males and their parents who need to know about the risks of the treatment on their future fertility and the possible present option of fertility preservation.

Abstract
OBJECTIVE The introduction of alternative systems in vivo is very important for cancer patients who are treated with gonadotoxic treatment. In this study, we examine the progression of the spermatogenesis process after human spermatogonial stem cell (SSCs) transplantation in vivo and in tissue culture conditions. MATERIALS AND METHODS Human SSCs were obtained from a Testicular Sperm Extractions (TESE) sample, and characterization of these cells was confirmed by detecting the promyelocytic leukemia zinc finger (PLZF) protein. These cells, after being labeled with Di-alkyl Indocarbocyanine (DiI), were transplanted to adult azoospermia mouse testes treated with Busulfan 40mg/kg. The host testicular tissue culture was then considered a test group and in vivo transplant a control group. After 8 weeks, immunohistochemical, morphometric and molecular studies were performed. RESULTS The results of morphometric studies indicated that the mean number of spermatogonia, spermatocytes, and spermatids in the test groups was significantly lower than in the control group (P<0.05) and most of the cells responded positively to DiI tracing. Immunohistochemical study in both groups revealed expression of PLZF, Synaptonemal complex protein 3 (SCP3) and Acrosin Binding Protein (ACRBP) proteins in spermatogonial cells, spermatocyte and spermatozoa, respectively. Also, PLZF, Transition Protein 1 (TP1) and Tektin-1 (Tekt1) human-specific genes had a significant difference in the between test groups and control groups (P<0.05) in molecular studies. CONCLUSION These results suggest that the conditions of testicular tissue culture after transplantation of SSCs can support spermatogenesis resumption, as well as in an in vivo condition.

Abstract
Optimization of tissue culture systems able to complete male germ cell maturation to post-meiotic stages is considered as an important matter in reproductive biology. Considering that hypoxia is one of the factors limiting the efficiency of organ culture, the aim of this study was to use isolated seminiferous tubules (STs), having more surface and less thickness, in an organotypic culture system in order to improve oxygen diffusion and reduce hypoxia. The mechanically separated STs embedded in agarose or alginate and 1-3-mm3 testicular tissue fragments of 3 adult mice were separately placed on the flat surface of agarose gel that was half-soaked in the medium. Survival and differentiation of germ cells using PLZF and SCP3 markers, identity of Sertoli cell using GATA4, cell proliferation with the Ki67 marker, and ST integrity using a ST scoring were evaluated up to 36 d at different culture times, each corresponding to the duration of one spermatogenic cycle. We observed a significantly reduced ST integrity in STs embedded in agarose or alginate on day 9 (versus tissue fragments p ≤ 0.05). There was no difference in the number of PLZF-positive cells between groups, but the number of SCP3 (in all-time points) and GATA4-positive cells was significantly higher in the culture of embedded STs. Although embedding STs can be useful for the progress of in vitro spermatogenesis, it makes them sensitive to degeneration. Further improvements are required to modify the air-liquid interface method to maintain ST integrity.

Abstract
Infertility is defined as the inability of couples to have a baby after one year of regular unprotected intercourse, affecting 10 to 15% of couples. According to the latest WHO statistics, approximately 50-80 million people worldwide sufer from infertility, and male factors are responsible for approximately 20-30% of all infertility cases. The diagnosis of infertility in men is mainly based on semen analysis. The main parameters of semen include: concentration, appearance and motility of sperm. Causes of infertility in men include a variety of things including hormonal disorders, physical problems, lifestyle problems, psychological issues, sex problems, chromosomal abnormalities and single-gene defects. Despite numerous efforts by researchers to identify the underlying causes of male infertility, about 70% of cases remain unknown. These statistics show a lack of understanding of the mechanisms involved in male infertility. This article focuses on the histology of testicular tissue samples, the male reproductive structure, factors affecting male infertility, strategies available to find genes involved in infertility, existing therapeutic methods for male infertility, and sperm recovery in infertile men.

Abstract
This paper aims at reviewing the fertility preservation strategies that could be considered in several conditions at risk of spermatogonial depletion such as 46,XY disorders of sexual development, Klinefelter syndrome and after gonadotoxic treatment in males highlighting current knowledge on diseases and processes involved in infertility as well as future directions along with their specific ethical issues. While sperm cryopreservation after puberty is the only validated technique for fertility preservation, for prepubertal boys facing gonadotoxic therapies or at risk of testicular tissue degeneration where testicular sperm is not present, cryopreservation of spermatogonial cells may be an option to ensure future parenthood. Promising results with transplantation and in vitro maturation of spermatogonial cells were achieved in animals but so far none of the techniques was applied in humans.

Abstract
Recently, significant progress has been made in ART for the treatment of male infertility. However, current ART has failed to help infertile patients with non-obstructive azoospermia, unless donor sperm is used. In fact, most couples wish to have their own genetically related child. Human induced pluripotent stem cells (hiPSCs) can be generated from patients’ somatic cells and in vitro derivation of functional germ cells from patient-specific iPSCs may provide new therapeutic strategies for infertile couples. The overall developmental dynamics of human primordial germ cells are similar to that in mice, but accumulating evidence suggests that there are crucial differences between human and mouse PGC specification. Unlike mouse iPSCs (miPSCs) in naive state, hiPSCs exhibit a primed pluripotency which possess less potential for the germ cell fate. Based on research in mice, male germ cells at different stages have been derived from hiPSCs with different protocols, including spontaneous differentiation, overexpression of germ cell regulators, addition of cytokines, co-culture with gonadal cells in vitro and xeno-transplantation. The aim of this review is to summarize the current advances in derivation of male germ cells from hiPSCs and raise the perspectives of hiPSCs in medical application for male infertility, as well as in basic research for male germ cell development.

Abstract
While in mice various studies have described the completion of spermatogenesis in vitro using either organotypic culture of prepubertal testicular tissue or 3D culture of isolated cells, in humans it has not been possible to achieve germ cell differentiation from immature testicular tissue (ITT). In our study, we evaluated the ability of human ITT to differentiate via a long-term organotypic culture of frozen–thawed 1 mm3 testicular fragments from five prepubertal boys in two different culture media. Tissue and supernatants were analyzed at regular intervals up to day 139. Sertoli cell (SC) viability and maturation was evaluated using immunohistochemistry (IHC) for SOX9, GDNF, anti-Mullerian hormone (AMH) and androgen receptor (AR), and AMH concentration in supernatants. Spermatogonia (SG) and proliferating cells were identified by MAGE-A4 (for SG) and Ki67 (for proliferating cells) via immunohistochemistry (IHC). Apoptotic cells were studied by active caspase 3. To evaluate Leydig cell (LC) functionality testosterone was measured in the supernatants and steroidogenic acute regulatory protein (STAR) IHC was performed. Germ cell differentiation was evaluated on Hematoxylin-Eosin histological sections, via IHC for synaptonemal complex 3 (SYCP3) for spermatocytes, Protein boule-like (BOLL) for spermatocytes and round spermatids, angiotensin-converting enzyme (ACE), protamine 2 and transition protein 1 (for elongated spermatids) and via chromogenic in situ hybridization (CISH). We reported the generation of meiotic and postmeiotic cells after 16 days of culture, as shown by the histological analyses, the presence of differentiation markers and the increase of haploid germ cells. We showed SC viability and maturation by a decrease of AMH secretion in the supernatants (p ≤ 0.001) while the number of SOX9 positive cells did not show any variation. A decrease of spermatogonia (p ≤ 0.001) was observed. The number of apoptotic cells did not vary. LC functionality was shown by the increase in STAR expression (p ≤ 0.007) and a peak in testosterone secretion, followed by a reduction (p ≤ 0.001) with stabilization. According to our knowledge, this is the first report of generation of haploid cells in human ITT. Differentiating germ cells have to be further evaluated for their ability to complete differentiation, their fecundability and epigenetic characteristics.

Abstract
Objective In vitro transplantation (IVT) of spermatogonial stem cells (SSCs) is one of the most recent methods in
transplantation in recent decades. In this study, IVT and SSCs homing on seminiferous tubules of host testis in organ culture
have been studied.
Materials and Methods In this experimental study, human SSCs were isolated and their identities were confirmed by tracking
their promyelocytic leukemia zinc finger (PLZF) protein. These cells were transplanted to adult azoospermia mouse testes
using two methods, namely, IVT and in vivo transplantation as transplantation groups, and testes without transplantation of
cells were assigned in the control group. Then histomorphometric, immunohistochemical and molecular studies were done
after 2 weeks.
Results After two weeks, histomorphometric studies revealed that the number of subsided spermatogonial cells (SCs)
and the percentage of tubules with subsided SCs in IVT and in vivo groups were significantly more than those in the
control group (P<0.05). Immunohistochemical studies in the transplantation groups confirmed that the PLZF protein
was expressed in the cells subsided on the seminiferous tubule. Quantitative reverse-transcription polymerase chain
reaction (qRT-PCR) demonstrated that the PLZF gene expression was only positive in the transplantation groups, but
it was not significantly different between the IVT group and the in vivo group (P>0.05).
Conclusion Testicular tissue culture conditions after SSC transplantation can help these cells subside on the seminiferous
tubule basement membrane.

Abstract
While the survival rate of children with cancer is increasing, preserving fertility for prepubertal boys is still a challenge. Although intracytoplasmic sperm injection (ICSI) using frozen sperms has revolutionized infertility treatment, it is not applicable for the patients who undergo chemotherapy before puberty since spermatogenesis has not begun. Therefore, preserving spermatogonial stem cells (SSCs) as an experimental option can be provided to prepubertal patients at a risk of damage or loss of their SSCs due to cancer treatments and developmental or genetic disorders. Using frozen SSCs in testicular tissue, successful SSC autotransplantation in mouse and nonhuman primates has shown a promising future for SSC-based cell therapy. Cryopreservation of testicular tissue containing SSCs is the first step to translate SSC-based cell therapy into clinical male infertility treatment, and in the investigation into SSCs, it is very important to evaluate their quantity and functionality during this process. This systematic review summarizes the published data on cryopreservation techniques in human testis tissue for potential utilization in future clinical applications.

Abstract
Meiotic progression in males is a process that requires the concerted action of a number of highly regulated cellular events. Errors occurring during meiosis can lead to infertility, pregnancy loss or genetic defects. Commencing at the onset of puberty and continuing throughout adulthood, continuous semi-synchronous waves of spermatocytes undergo spermatogenesis and ultimately form haploid sperm. The first wave of mouse spermatocytes undergoing meiotic initiation appear at day 10 post-partum (10 dpp) and are released into the lumen of seminiferous tubules as mature sperm at 35 dpp. Therefore, it is advantageous to utilize mice within this developmental time-window in order to obtain highly enriched populations of interest. Analysis of rare cell stages is more difficult in older mice due to the contribution of successive spermatogenic waves, which increase the diversity of the cellular populations within the tubules. The method described here is an easily implemented technique for the cytological evaluation of the cells found within the seminiferous tubules of mice, including spermatogonia, spermatocytes, and spermatids. The tubule squash technique maintains the integrity of isolated male germ cells and allows examination of cellular structures that are not easily visualized with other techniques. To demonstrate the possible applications of this tubule squash technique, spindle assembly was monitored in spermatocytes progressing through the prophase to metaphase I transition (G2/MI transition). In addition, centrosome duplication, meiotic sex chromosome inactivation (MSCI), and chromosome bouquet formation were assessed as examples of the cytological structures that can be observed using this tubule squash method. This technique can be used to pinpoint specific defects during spermatogenesis that are caused by mutation or exogenous perturbation, and thus, contributes to our molecular understanding of spermatogenesis.

Abstract
Infertile couples including cancer survivors stand to benefit from gametes differentiated from embryonic or induced pluripotent stem (ES/iPS) cells. It remains challenging to convert human ES/iPS cells into primordial germ-like cells (PGCLCs) en route to obtaining gametes. Considerable success was achieved in 2016 to obtain fertile offspring starting with mouse ES/iPS cells, however the specification of human ES/iPS cells into PGCLCs in vitro is still not achieved. Human ES cells will not yield patient-specific gametes unless and until hES cells are derived by somatic cell nuclear transfer (therapeutic cloning) whereas iPS cells retain the residual epigenetic memory of the somatic cells from which they are derived and also harbor genomic and mitochondrial DNA mutations. Thus, they may not be ideal starting material to produce autologus gametes, especially for aged couples. Pluripotent, very small embryonic-like stem cells (VSELs) have been reported in adult tissues including gonads, are relatively quiescent in nature, survive oncotherapy and can be detected in aged, non-functional gonads. Being developmentally equivalent to PGCs (natural precursors to gametes), VSELs spontaneously differentiate into gametes in vitro. It is also being understood that gonadal stem cells niche is compromised by oncotherapy and with age. Improving the gonadal somatic niche could regenerate non-functional gonads from endogenous VSELs to restore fertility. Niche cells (Sertoli/mesenchymal cells) can be directly transplanted and restore gonadal function by providing paracrine support to endogenous VSELs. This strategy has been successful in several mice studies already and resulted in live birth in a woman with pre-mature ovarian failure.

Abstract
Although the technique of intracytoplasmic sperm injection (ICSI) has been a revolution in the alleviation of male infertility, the use of testicular sperm for ICSI was a formerly unseen breakthrough in the treatment of the azoospermic man with primary testicular failure. At the clinical level, different procedures of testicular sperm retrieval (conventional TESE, micro-TESE, FNA/TESA, MESA, PESA) are being performed, the choice is mainly based on the cause of azoospermia (obstructive versus non-obstructive) and the surgeon's skills. At the level of the IVF laboratory, mechanical procedures to harvest the sperm from the tissue may be combined with enzymatic treatment in order to increase the sperm recovery rates. A number of techniques have been developed for viable sperm selection in males with only immotile testicular sperm available. However, large, well-designed studies on the benefit and safety of one over the other technique are lacking. Despite all the available methods and combinations of laboratory procedures which have a common goal to maximize sperm recovery from testicular samples, a large proportion of NOA patients fail to father a genetically own child. Advanced technology application may improve recovery rates by detection of the testicular foci with active spermatogenesis and/or identification of the rare individual sperm in the testicular suspensions. On the other hand, in vitro spermatogenesis or sperm production from embryonic stem cells or induced pluripotent stem cells might be future options. The present review summarizes the available strategies which aim to maximize sperm recovery from surgically retrieved samples.

Abstract
STUDY QUESTION Is an organotypic culture system able to provide the appropriate testicular microenvironment for in-vitro maturation of human immature testicular tissue (ITT)? SUMMARY ANSWER Our organotypic culture system provided a microenvironment capable of preserving seminiferous tubule (ST) integrity and Leydig cell (LC) functionality and inducing Sertoli cell (SC) maturation. WHAT IS KNOWN ALREADY Cryopreservation of human ITT is a well-established strategy to preserve fertility in prepubertal boys affected by cancer, with a view for obtaining sperm. While spermatogenesis in mice has been replicated in organotypic culture, yielding reproductively efficient spermatozoa, this process has not yet been achieved in humans. STUDY DESIGN, SIZE, DURATION The aim of this study was to in vitro mature frozen-thawed ITT. To this end, 1 mm3 tissue fragments from three prepubertal patients aged 2 (P1), 11 (P2) and 12 (P3) years were placed in organotypic culture for 139 days. Culture media, supplemented with either testosterone or hCG, were compared. PARTICIPANTS/MATERIALS, SETTING, METHODS ST integrity and tissue viability were assessed by histological score and lactate dehydrogenase (LDH) levels in supernatants. Spermatogonia (SG), proliferating cells and proliferating SG were identified by the use of MAGE-A4 and Ki67 immunohistochemical markers. Glial cell line-derived neurotrophic factor (GDNF) was used as a marker of SC functionality, while SC maturation was evaluated by androgen receptor (AR), anti-Müllerian hormone (AMH) immunohistochemistry (IHC) and AMH immunoenzymatic assay. LC functionality was determined by testosterone levels in supernatants and by 3β-hydroxysteroid dehydrogenase (3β-HSD) IHC. Apoptosis was studied by IHC with active caspases 3 and 8 and by TUNEL (terminal deoxynubocleotidyl transferase-mediated dUTP nick end labeling) analysis. MAIN RESULTS AND THE ROLE OF CHANCE Tissue viability was preserved, as demonstrated by the decrease in and stabilization of LDH release, and evolution of ST scoring, with the percentage of well-preserved STs showing no statistical differences during culture in either medium. GDNF was expressed until Day 139, demonstrating SC functionality. Moreover, a significant reduction in AMH expression and release indicated SC maturation. Testosterone concentrations in supernatants increased in both culture media, demonstrating LC functionality with paracrine interactions. SG were present up to Day 139, although the ratio between MAGE-A4-positive cells and well-preserved tubules was significantly reduced over the course of culture (P ≤ 0.001). SCs exhibited a decreased proliferation rate over time (P ≤ 0.05). The proliferation rate of SG remained stable until Day 64, but over the total culture period (139 days), it was found to have decreased (P ≤ 0.05). The number of apoptotic cells did not vary during culture, nor was any statistical difference observed between the two culture media for any of the studied parameters. LARGE SCALE DATA N/A LIMITATIONS, REASONS FOR CAUTION: Loss of SG constitutes a limitation for evaluating full functionality of spermatogonial stem cells and warrants further investigation. The scarcity of human immature material is the reason for the limited amount of tissue available for experiments, precluding more comprehensive analysis. WIDER IMPLICATIONS OF THE FINDINGS Our culture system, mimicking the peripubertal testicular microenvironment with SC maturation, LC functionality and preserved paracrine interactions, and the first to use human ITT, opens the door to a deeper understanding of niche and culture conditions to obtain sperm from cryostored ITT, with the ultimate goal of restoring fertility after gonadotoxic treatments. STUDY FUNDING/COMPETING INTERESTS This project was supported by a grant from the Fond National de la Recherche Scientifique de Belgique (grant Télevie N° 7.4554.14F and N° 7.4512.15F) and the Fondation Salus Sanguinis.
