The NLRP3 inflammasome: molecular activation and regulation in spermatogenesis and male infertility; a systematic review. Basic Clin Androl 2022; 32:8.

Abstract
Background Infertility related to varicocele, infections, metabolic dysfunctions, oxidative stress and environmental toxicants is also associated with inflammatory processes that ultimately lead to the activation of the inflammasome pathway (IP). IP is classically activated by DAMPs, MAMPs or LAMPs, which stand for Damage-, Microbe- or Lifestyle-Associated Molecular Patterns, respectively. The most important player in IP activation is the NLRP3 (NOD[Nuclear oligomerization domain]-, LRR[Leucine rich repeat]- and pyrin domain-containing protein 3) which functions as an intracellular sensor of D/M/L-AMPs resulting in activation of caspase-1, promotion of apoptosis, pyroptosis and generation of inflammatory cytokines. This review addresses the question of whether IP activation might be associated with male infertility situations. Results & conclusions We conducted a systematic review of articles published in the Google Scholar, and PubMed databases through October 2021. It turns out that inflammasome activation and its consequences including cytokine storms, apoptosis and pyroptosis could be associated with the reduced sperm count as well as the structural and functional sperm defects recorded in several situations associated with male infertility suggesting that anti-inflammatory therapeutic strategies could be possibly considered to restore male fertility in future research.

Abstract
Spermatogenesis is fundamental to the establishment and maintenance of male reproduction, whereas its abnormality results in male infertility. Somatic cells, including Leydig cells, myoid cells, and Sertoli cells, constitute the microenvironment or the niche of testis, which is essential for regulating normal spermatogenesis. Leydig cells are an important component of the testicular stroma, while peritubular myoid cells are one of the major cell types of seminiferous tubules. Here we addressed the roles and mechanisms of Leydig cells and myoid cells in the regulation of spermatogenesis. Specifically, we summarized the biological features of Leydig cells and peritubular myoid cells, and we introduced the process of testosterone production and its major regulation. We also discussed other hormones, cytokines, growth factors, transcription factors and receptors associated with Leydig cells and myoid cells in mediating spermatogenesis. Furthermore, we highlighted the issues that are worthy of further studies in the regulation of spermatogenesis by Leydig cells and peritubular myoid cells. This review would provide novel insights into molecular mechanisms of the somatic cells in controlling spermatogenesis, and it could offer new targets for developing therapeutic approaches of male infertility.

Abstract
Spermatogenesis is the process of the proliferation and differentiation of spermatogonial stem cells (SSCs) to generate sperm. Leukemia patients show impairment in some of the endocrine hormones that are involved in spermatogenesis. They also show a decrease in semen parameters before and after thawing of cryopreserved samples compared to a control. The mechanisms behind these effects have not yet been described. This review summarizes the effect of leukemia on semen parameters from adult patients and highlights feasible suggested mechanisms that may affect impairment of spermatogenesis in these patients. We suggest the possible involvement of leukemia in disturbing hormones involved in spermatogenesis, and the imbalance in testicular paracrine/autocrine factors involved in the formation of SSC niches that control their proliferation and differentiation. Understanding the mechanisms of leukemia in the impairment of spermatogenesis may lead to the development of novel therapeutic strategies mainly for prepubertal boys who do not yet produce sperm.

Abstract
PROBLEM The aim of this study was to examine the expression levels of IL-1 family members, IL-6, IL-10, TNF family, SCF, and c-kit in infertile patients with idiopathic non-obstructive azoospermia (NOA) compared with men with normal spermatogenesis. METHOD OF STUDY We analyzed 20 testicular biopsy samples with Affymetrix Human Gene 1.0 ST microarrays (Affymetrix, Santa Clara, CA, USA). Sixteen of them were obtained from patients with various types of NOA and four with normal spermatogenesis. RESULTS The comparative analysis of normal and pathological group demonstrated a different expression level of IL1-RA gene. It was also observed that the gene expression levels for IL1-R1, CASP1, and stem cell factor (SCF) were upregulated in the Sertoli-cell-only syndrome group in comparison with the control one (P < 0.05). CONCLUSION The microarray analysis showed the expression level of all investigated paracrine/autocrine factors at one go, and therefore, the possible interaction between these genes could be examined.

Abstract
Azoospermia due to obstructive and non-obstructive mechanisms is a common manifestation of male infertility accounting for 10-15% of such cases. Known genetic factors are responsible for approximately 1/3 of cases of azoospermia. Nonetheless, at least 40% of cases are currently categorized as idiopathic and may be linked to unknown genetic abnormalities. It is recommended that various genetic screening tests are performed in azoospermic men, given that their results may play vital role in not only identifying the etiology but also in preventing the iatrogenic transmission of genetic defects to offspring via advanced assisted conception techniques. In the present review, we examine the current genetic information associated with azoospermia based on results from search engines, such as PUBMED, OVID, SCIENCE DIRECT and SCOPUS. We also present a critical appraisal of use of genetic testing in this subset of infertile patients.
