Scrotum. The bag of skin that holds and helps to protect the testicles.

What is around the testis?

Each cremaster muscle surrounds one of the testicles and its spermatic cord. The muscle helps to move the testicle toward and away from the body to maintain the ideal temperature for sperm production. This is why the scrotum hangs lower in warm conditions and closer to the body in cold weather.

Why are testis located outside the abdominal cavity?

Solution: The testes is located outside the abdominal cavity because sperm formation requires a temperature lower than the body temperature. It is because scrotum has a temperature 1-3 degree Celsius lower than the normal body temperature, which is essential for the production of sperm or male gametes.

What is Dartos muscle?

The dartos muscle is the thin rugated fascial muscle of the scrotum made of smooth muscle. Hence it is also referred to as dartos fascia or simply the dartos. It forms from the subcutaneous tissue of the scrotum and base of the penis and attaches to the scrotal skin and fibrous midline septum between the testes.

What are testicular lobules?

The testicle is divided into parts called lobules. Each lobule contains tiny U-shaped tubes called seminiferous tubules. There are about 800 seminiferous tubules tightly coiled within each testicle. The seminiferous tubules open into a series of uncoiled, interconnected channels called the rete testis.

What is Buck’s fascia?

Buck’s fascia is the deep layer of the penile fascia that covers both the corpora cavernosa and the corpus spongiosum in separate fascial compartments.

What is the function of Bulbourethral gland?

Bulbourethral glands are also known as Cowper glands, provide mucus proteins that lubricate the urethra and counteract the acidity of any urine leftover in the urethra.

How are the testes protected from the scrotum?

As they descend, the testes also push layers of the anterior abdominal wall (internal and external oblique muscles and the transversalis fascia) and extend them into the scrotum. These extensions of the anterior abdominal wall create a musculofascial pouch that protects the testes within the scrotum.

What do you need to know about the testes?

What is the function of the testicle in a male?

Testicle or testis (plural testes) is the male reproductive gland or gonad in all animals, including humans. It is homologous to the female ovary . The functions of the testes are to produce both sperm and androgens , primarily testosterone .

Why are the testes located outside the abdomen?

The location of the testes outside the abdomen has evolved, at least in part, because the testes need to stay cooler than body temperature to fully function. Most males are born with two testicles, collectively known as the testes. These soft, egg-shaped organs are located inside the scrotum.
