Phosphodiesterases, particularly the type 5 isoform (PDE5), have gained recognition as pivotal regulators of male reproductive physiology, exerting significant influence on testicular function, sperm maturation, and overall fertility potential. Over the past several decades, investigations have expanded beyond the original therapeutic intent of PDE5 inhibitors for erectile dysfunction, exploring their broader reproductive implications. This narrative review integrates current evidence from in vitro studies, animal models, and clinical research to clarify the roles of PDEs in effecting the male reproductive tract, with an emphasis on the mechanistic pathways underlying cyclic nucleotide signaling, the cellular specificity of PDE isoform expression, and the effects of PDE5 inhibitors on Leydig and Sertoli cell functions.

The microbiome-gut-testis axis has emerged as a significant area of interest in understanding testicular cancer, particularly testicular germ cell tumors (TGCTs), which represent the most common malignancy in young men. The interplay between the gut and testicular microbiomes is hypothesized to influence tumorigenesis and reproductive health, underscoring the complex role of microbial ecosystems in disease pathology. The microbiome-gut-testis axis encompasses complex interactions between the gut microbiome, systemic immune modulation, and the local microenvironment of the testis.

Objectives: Nonalcoholic fatty liver disease (NAFLD) is known to disrupt testicular anti-oxidant capacity, leading to oxidative stress (OS) that can negatively affect male fertility by damaging sperm DNA. Heat shock proteins (HSP70 and HSP90), in association with transitional proteins (TP1 and TP2), play crucial roles in protecting sperm DNA integrity in oxidative conditions. Whiteleg shrimp protein hydrolysates (HPs) exhibit anti-oxidant properties, prompting this study to explore the potential of HPs in ameliorating NAFLD-induced testicular damage.

Objectives: This experiment was carried out to investigate the protective effects of curcumin (CUR) on testicular damage induced by the valproic acid (VPA) administration.
Materials And Methods: Male Wistar-Albino rats (n=28, 250-300 g) were randomly divided into four groups: Control (1 ml saline, oral), VPA (500 mg/kg, IP), CUR (200 mg/kg, oral), or VPA+CUR (500 mg/kg, VPA, IP plus 200 mg/kg CUR, oral). The treatments were applied for 14 days.
