Why is testicle skin so thin?

Why is testicle skin so thin?

In hot conditions, the skin loosens to prevent the testicles from overheating. The looser skin allows the balls to hang away from the warm body and encourages airflow around the scrotum to keep the area cool. As such, even in younger people, the testicles will typically sag a bit.

How thick is a testicle?

Each testis weighs 0.35 to 0.5 ounces (10 to 15 grams), according to Virtual Medical Centre (VMC). They are typically 2 inches (5 centimeters) long, 1.2 inches (3 cm) wide and 1 inch (2.5 cm) thick.

What does the skin of the scrotum look like?

The skin of the scrotum is thin and wrinkly. Before puberty, the scrotal skin is the same color as the skin found elsewhere on the body. However, during puberty the scrotum will change color and become darker and thinner. The scrotal skin also contains blood vessels and nerves. One particular nerve, the posterior scrotal nerve, is worthy of note.

What is the normal temperature of the human scrotum?

The temperature in the human scrotum is 3.1 °C (5.6 °F) lower than the normal temperature within the body (37 °C, or 98.6 °F). Spermatogenesis requires this lower temperature, and an increase in scrotal temperature of 3 °C (5.4 °F) can lead to a decrease in viable sperm.

What is the pathophysiology of the scrotum?

Embryologically, the scrotum originates from the genital swellings that meet ventral to the anus and unite to form the two scrotal sacs. A median raphe of fibrovascular connective tissue separates both halves. Median raphe cysts of the perineum are uncommon congenital lesions of the male genitalia.

What is Scrotodynia (male genital skin burning syndrome)?

Scrotodynia has also been referred to as ‘the male genital skin burning syndrome’. Men have described pain, burning or abnormally sensitive scrotal skin over a prolonged period of time. There are no abnormalities visible when the scrotal skin is examined.
