The testes and epididymis are paired structures, located within the scrotum. The testes are the site of sperm production and hormone synthesis, while the epididymis has a role in the storage of sperm. In this article, we shall look at the anatomy of the testes and epididymis - their structure, vasculature, innervation and clinical correlations.

The testes are male sex glands that have both an endocrine and exocrine function. The testes are oval-shaped reproductive structures that are found in the scrotum and separated by the scrotal septum. The shape of the testes is bean-shaped and measures three cm by five cm in length and 2 cm to 3 cm in width. When palpated through the scrotum, the testes are smooth and soft.

The two testes, or testicles, which usually complete their descent into the scrotum from their point of origin on the back wall of the abdomen in the seventh month after conception, are suspended in the scrotum by the spermatic cords.Each testis is 4 to 5 cm (about 1.5 to 2 inches) long and is enclosed in a fibrous sac, the tunica albuginea.This sac is lined internally by the tunica vasculosa

An image depicting the testes and epididymis can be seen below. Male reproductive organs, sagittal section. The testis (from the Greek word orchis) is the male gland important for both reproductive (exocrine) and endocrine functions. Initially, it begins as an undifferentiated gonad in the retroperitoneal area.

Testes. The male gonads, testes or testicles, begin their development high in the abdominal cavity, near the kidneys.During the last two months before birth, or shortly after birth, they descend through the inguinal canal into the scrotum, a pouch that extends below the abdomen, posterior to the penis.Although this location of the testes, outside the abdominal cavity, may seem to make them

At birth, testes measure approximately 1.5 cm (length) x 1 cm (width), reaching ~4 mL volume at puberty 1. Normal adult testes are ovoid and measure approximately 3 cm (AP) x 2-4 cm (TR) x 3-5 cm (length), with a volume of 12.5-19 mL 2. However, the size of the testes decreases with age. From the mediastinum testis, several radiating septa
