Organ-on-a-chip culture systems using human organ tissues provide invaluable preclinical insights into systemic functions . This study aimed to develop a novel human testicular tissue chip within a microfluidic device employing computer-aided design software and photolithography technology. Polydimethylsiloxane was used as the primary material to ensure marked gas permeability and no biotoxicity, enabling effective mimicry of the testicular microenvironment.

Cisplatin is an antineoplastic drug that exhibits toxicity dependent on dosage and has adverse reproductive effects. (Bitter melon) is a natural vegetable plant; its active ingredients possess antioxidant, apoptotic, antiproliferative, hypoglycemic, and other therapeutic properties. This study evaluates the effect of the administration of bitter melon extract, cisplatin, and cisplatin/bitter melon cotreatment on liver and kidney functions, serum and testicular oxidative status, testis histology, and sperm parameters.

Context: Pathogenic variants in the TBCE gene, encoding tubulin-specific chaperone E crucial for tubulin folding, are linked to three severe neurodevelopmental disorders: Hypoparathyroidism-retardation-dysmorphism (HRD) syndrome, Kenny-Caffey syndrome type 1, and progressive encephalopathy with amyotrophy and optic atrophy.

Objective: We identified patients with a novel, milder TBCE-associated phenotype and aimed to characterize it at the clinical and molecular levels.

Materials And Methods: We conducted splicing analysis using deep NGS sequencing of RT-PCR products and detected TBCE through Western blotting.

Background: Di(2-ethylhexyl) phthalate (DEHP) is a commonly used plasticizer known for its toxic effects on the male reproductive system. Green tea polyphenols (GTPs), recognized for their antioxidant and anti-inflammatory properties, have demonstrated protective effects on various organs, but the mechanisms by which GTPs mitigate DEHP-induced testicular damage remain unclear.

Methods: Healthy male C57BL/6 J mice were divided into five groups: Control, DEHP, DEHP + GTP treatment, GTP, and Oil groups.

Background: Congenital hypothyroidism (CH) is a pathology that affects various organs, including the testicles. The mechanisms by which this condition alters fertility is unknown. This study aimed at determining if experimental CH affects gonocyte differentiation and arrests meiosis; and the possible role of the Sertoli cell (SC) in this condition.
