Male Anatomy • Primary Organ – testes, genetically determined in mammals - testis releases hormones that then control the development of secondary sex characteristics - Secondary Organs – internal duct system • e.g., vas deferens, epididymus – external genitalia • Secondary Sexual Characters – e.g., antlers, coloration, facial hair. Mature testis is approximately plum-shaped, cm long. In its usual position in the scrotum, it has a wider margin pointing posteriorly and a narrower margin pointing anteriorly. At its posterior border, the mediastinum testis, also called rete (net) testis, contains the blood vessels, nerves and ductus deferens, that enter and leave the. pathology. This procedure was once mainly used for the diagnosis and for treatment schedule of male infertility. Presently, the procedure can be used also to evaluate endocrinopathies and disorders of other organs which may manifest their effects on testicular function, such as adrenogenital syndrome.

Topics discussed in this compilation include the roles and regulatory mechanism of proton pumping V-ATPase in spermatozoa and epididymis physiology; oxidative stress as a converging mechanism of testicular damage; the pathophysiology of the testis after.
In this lecture, you’re going to learn about the histological structure and function of the testis. It’s a major organ in the male reproductive system.
In another lecture, I’m going to talk about the accessory glands, and also ducts that are involved with transporting products from the testis, the spermatozoa. At the end of this lecture, I’d like you to be clearly. or heat gain. Now let’s look at the testis in more detail.

Drawing showing the appendix of testis. (WC/Gray's Anatomy) Appendix of the testis is a benign structure of the testis that is a remnant of the Muellerian duct.
It should not be confused with the appendix of the epididymis. Embryology – formation of a testis. A brief review of testis formation is essential to understand how disorders of this process could lead to seemingly diverse abnormalities, such as cryptorchidism, abnormal spermatogenesis, tumors of the testis or male excurrent duct system, or aplasia of male genitalia [21, 22].The sex-determining region of the genome is located on the Cited by: Yield of Testis Pathology in Older Children and Adolescents with Cryptorchidism Joseph W.

Sertoli cells: surround the germ cells and have important tasks in support and nutrition of germ cells, formation of the blood-testis barrier, phagocytosis of spermatid remains, secretion of inhibin (control of FSH), and transmission of hormonal stimuli.
Sertoli cells are located on the basement membrane of seminiferous tubules and reach with its cytoplasm to luminal. 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. Retractile testis is often bilateral and most common in boys between 5 and 6 years of age.
Hypospadias and inguinal hernias are the most common associated anomalies seen with undescended testis. Undescended testis (UDT) is a common abnormality, affecting about 1/20 males at birth.
Half of these have delayed testicular descent, with the testis in the scrotum by weeks after term. Beyond this spontaneous descent is rare.
Current treatment recommendations are that UDT beyond 3 months need surgery between months of age. Some children have scrotal Cited by: 2.

Torsion of the appendix testis is not an uncommon cause of acute hemiscrotum. It is frequently misdiagnosed as acute epididymitis, orchitis, or torsion of testis.
Though conservative management is the treatment of choice for this condition, prompt surgical intervention is warranted when testicular torsion is suspected.

Welcome to the updated version of Pathology for Urologists. This program was designed to help Urology residents and fellows familiarize themselves with the pathologic features of common urologic entities.

The male gonad is the testis (pl, testes). The initial difference in male and female gonad development are dependent on testis-determining factor (TDF) the protein product of the Y chromosome SRY gene. Recent studies have indicated that additional factors may also be required for full differentiation.
Undescended testis (UDT) is the most common disorder of sexual development in boys and affects % of male newborns. Although approximately half of newborn UDTs descend spontaneously, some boys develop an ascending testis later in childhood.

The book’s emphasis on functional interpretation of the images, supplemented by clinical data, make it a unique tool for clinical management. This approach is intended to increasingly familiarize clinicians with the Author: Andrea M. Isidori, Andrea Lenzi.
The natural history of acquired UDT is that the testes are in the scrotum at six months of age, but ascend out of the scrotum between one and five years of age. 16 From about five years of age, the testes are located in the groin, but then spontaneously descend again at puberty (thought to be a secondary effect of androgen).
