Infants
A hard, enlarged painless testicle may indicate:
Tumor
Varying degrees of maturation should be classified according to the:

Protrusion of a peritoneal-lined sac through some defects in the abdominal wall
Hernia
Hernias that are more common in women
Femoral hernias (fossa ovalis)
The inability to replace the foreskin to its usual position after it has been retracted behind the glans
Paraphimosis

Peyronie Disease
Penile carcinomas typically occur in:
Uncircumcised men who practice poor hygiene
Nontender, smooth, firm mass that results from fluid accumulation in the tunica vaginalis.
Will transilluminate.
Hydrocele
