## Summary

The **testes** are found in the **scrotum**. The **epididymis** is located on the **posterolateral testicular wall**. The testes are held inferiorly to the abdomen via the spermatic cord. In **embryonic life** the testes are found on the posterior abdominal wall, but during development they descend to the scrotum.

## Anatomy

The testes **contain seminiferous tubules** that are lined by **Sertoli cells **that are involved in the reproductive functioning of males. Within the scrotum the testes are protected by the **tunica vaginalis**. The tunica vaginalis is enclosed by the fibrous **tunica albuginea**.

The **epididymis** is an important connection of the testes that transports sperm from the testes to the prostatic urethra for ejaculation.

The **cremaster** muscle arises from the internal oblique and inserts in the tunica vaginalis.

Its action is movement (raising and lowering) of the scrotum.

It is supplied by the **cremasteric artery**, and innervated by the **genital branch of the genitofemoral nerve (L1,L2)**. The testes also receive blood from the testicular arteries. Their venous drainage is via the pampiniform plexus of the scrotum that course around the testicular artery.

## Clinical points

- Abnormal amounts of fluid can accumilate betwen the layers of the tunica vaginalis. This is called a hydrocele.
- Twisting of the spermatic cord can lead to compromise of the blood supply to the testis. This is called testicular torsion and it is a urological emergency.
