The Testes and their Coverings -The testes are two glandular organs, which secrete the semen; they are suspended in the scrotum by the spermatic cords. The average testicular volume is 20 cc in healthy young men and decreases in elderly men. Normal longitudinal length of the testis is approximately 4.5 to 5.1 cm.
At an early period of foetal life the testes are contained in the abdominal cavity, behind the peritoneum. Before birth they descend to the inguinal canal, along which they pass with the spermatic cord, and, emerging at the subcutaneous inguinal ring, they descend into the scrotum, becoming invested in their course by coverings derived from the serous, muscular, and fibrous layers of the abdominal parietes, as well as by the scrotum.
Below are some some common conditions, diagnostics and treatments in relation to testes.
