testis [tes´tis] (L.) the male gonad; either of the paired, egg-shaped glands normally found in the scrotum; called also testicle. The testes produce the spermatozoa (the male reproductive cells) and testosterone (the male sex hormone), which is responsible for the secondary sex characters of the male. A, Testis; B, production of spermatozoa. If the. Cryptorchidism is the most common genital problem encountered in pediatrics. Cryptorchidism literally means hidden or obscure testis and generally refers to an undescended or maldescended testis. Despite more than a century of research, many aspects of cryptorchidism are not well defined and remain controversial.
Cryptorchidism is the absence of one or both testes from the word is from the Greek κρυπτός, kryptos, meaning hidden, and ὄρχις, orchis, meaning is the most common birth defect of the male genital tract. About 3% of full-term and 30% of premature infant boys are born with at least one undescended lty: Medical genetics. Start studying Chapter Reproductive System (study guide, book, evolve).

Developed in a male fetus near the kidneys, and descend to the scrotum about 2 months before birth. Each testis is enclosed by a layer of fibrous connective tissue called tunica Size: 1MB. Testis, in animals, the organ that produces sperm, the male reproductive cell, and androgens, the male hormones.
In humans the testes occur as a pair of oval-shaped organs. They are contained within the scrotal sac, which is located directly behind the penis and in front of the anus. In humans each. The testes are two oval-shaped organs in the male reproductive system.
We’ll go over the different structures within each testis and how they function. You’ll also learn about the kinds of. Lisa Jones MD, PhD, E. Scott Pretorius MD, in Radiology Secrets Plus (Third Edition), 15 Describe the normal appearance of the testis and epididymis on US.
Each testis is ovoid, homogeneous in echotexture, and measures approximately 3 × (2 to 4) × (3 to 5) cm. Centrally within each testis is an echogenic linear structure, the mediastinum testis, which is an invagination of the.
Testicular cancer is a disease in which malignant (cancer) cells form in the tissues of one or both testicles. The testicles are 2 egg-shaped glands located inside the scrotum (a sac of loose skin that lies directly below the penis).The testicles are held within the scrotum by the spermatic cord, which also contains the vas deferens and vessels and nerves of the : PDQ Adult Treatment Editorial Board.

Note: In cases of the removal of one testis as the result of a service-incurred injury or disease, other than an undescended or congenitally undeveloped testis, with the absence or nonfunctioning of the other testis unrelated to service, an evaluation of 30 percent will be assigned for the service-connected testicular loss.
Testis, underscended, or congenitally undeveloped is not a ratable disability. Treat the diseases affecting large animals. Veterinary Medicine, 11th Edition provides up-to-date information on the diseases of horses, cattle, sheep, goats, and pigs.

Figure 2. The Scrotum and Testes. This anterior view shows the structures of the scrotum and testes. Testes. The testes (singular = testis) are the male gonads—that is, the male reproductive produce both sperm and androgens, such as testosterone, and are active throughout the reproductive lifespan of the male.
Types of Scrotal and Testicular Conditions There are quite a few types of testicular and scrotal conditions. Testicular cancer is likely the most well-known condition, but there are many other benign conditions of the testes and scrotum that range from minor to life-threatening.
The testes are twin oval-shaped organs about the size of a large grape. They are located within the scrotum, which is the loose pouch of skin that hangs outside the body behind the penis. While this location makes the testes vulnerable to injury (they have no muscles or bones to shield them), it provides a cooler temperature for the organs.

Undescended testicle: Testicular cancer happens more often in men who were born with a condition called cryptorchidism. Early in a pregnancy, the testes form in the male baby’s lower belly. Testicular pain, or pain in the testicle or testicles are caused by a variety of diseases or conditions such as testicular trauma, testicular torsion, varicoceles, testicular cancer, epididymitis caused by infections such as STDs, and orchitis.
Common symptoms of pain in the testicle or testicles are abdominal pain, urinary pain or incontinence.Clinically evident testicular disease at diagnosis is a rare event. 86, 87 Before the advent of modern-day chemotherapy regimens, testicular relapse was a significant obstacle to cure.
87, 88 Because of the high rate of relapse and because of the high frequency of leukemic infiltration of testes (64% to 92%) demonstrated in autopsy series, Therefore, if the testicular artery is ligated, e.g., during a Fowler-Stevens orchiopexy for a high undescended testis, the testis will usually survive on these other blood supplies.
Lymphatic drainage of the testes follows the testicular arteries back to the paraaortic lymph nodes, while lymph from the scrotum drains to the inguinal lymph : Testicular artery.
