PATHOLOGY

Detailed explanation-1: -The beginning of testicular development is with the formation of the genital ridge. The origin of the genital ridge is from the intermediate mesoderm. The intermediate mesoderm forms paired structures that reside beside the dorsal mesentery, specifically in the coelomic cavity.

Detailed explanation-2: -They are typically 2 inches (5 centimeters) long, 1.2 inches (3 cm) wide and 1 inch (2.5 cm) thick. The scrotum is a loose sack of skin that protects the testicles and acts as a climate control system. The testes must be at a temperature slightly cooler than the body temperature for normal sperm development.
