Ectopic Testis
A ectopic testis is a testicle that, although not an undescended testicle, has taken a non-standard path through the body and ended up in an unusual location. The positions of the ectopic testis may be: in the lower part of the abdomen, front of thigh, femoral canal, skin of penis or behind the scrotum. The testis is usually developed, and accompanied by an indirect inguinal hernia. It may be divorced from the epididymis which may lie in the scrotum. See also * Cryptorchidism * Orchiopexy Orchiopexy (or orchidopexy) is a surgery to move and/or permanently fix a testicle into the scrotum. While orchiopexy typically describes the operation to surgically correct an undescended testicle, it is also used to resolve testicular torsion. ...

Urology
Urology (from Greek οὖρον ''ouron'' "urine" and '' -logia'' "study of"), also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary-tract system and the reproductive organs. Organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate, and penis). The urinary and reproductive tracts are closely linked, and disorders of one often affect the other. Thus a major spectrum of the conditions managed in urology exists under the domain of genitourinary disorders. Urology combines the management of medical (i.e., non-surgical) conditions, such as urinary-tract infections and benign prostatic hyperplasia, with the management of surgical conditions such as bladder or prostate cancer, kidney stones, congenital abnormalities, traumatic injury, and stress incontinence.

Testicle
A testicle or testis (plural testes) is the male reproductive gland or gonad in all bilaterians, including humans. It is homologous to the female ovary. The functions of the testes are to produce both sperm and androgens, primarily testosterone. Testosterone release is controlled by the anterior pituitary luteinizing hormone, whereas sperm production is controlled both by the anterior pituitary follicle-stimulating hormone and gonadal testosterone. Structure Appearance Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's anatomy. For 85% of men, the right testis hangs lower than the left one. Measurement and volume The volume of the testicle can be estimated by palpating it and comparing it to ellipsoids of known sizes. Another method is to use caliper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undescended Testicle
Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Greek () 'hidden' and () 'testicle'. It 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 testis. However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall. Cryptorchidism may develop after infancy, sometimes as late as young adulthood, but that is exceptional. Cryptorchidism is distinct from monorchism, the condition of having only one testicle. Though the condition may occur on one or both sides, it more commonly affects the right testis. A testis absent from the normal scrotal position may be: # Anywhere along the "path of descent" from high in the posterior (retroperitoneal) abdomen, just below the kidney, to the inguinal ring ...

Orchiopexy
Orchiopexy (or orchidopexy) is a surgery to move and/or permanently fix a testicle into the scrotum. While orchiopexy typically describes the operation to surgically correct an undescended testicle, it is also used to resolve testicular torsion. Indications Undescended testicle Undescended testicles affect 1% of males and are 10% bilateral. The cause is unknown, with a small percentage associated with developmental abnormalities or chromosomal aberrations. Early orchiopexy reduces the risks for cancer and sterility in males with cryptorchidism, or undescended testes. Cryptorchidism is definitively diagnosed after 1 year of age, as testicular descent may occur after birth. Surgical placement into the scrotum is recommended by 18 months to decrease the likelihood of testicular cancer, testicular atrophy, and sterility. Cryptorchidism is associated with tubular atrophy and sterility. In addition, cryptorchid testes carry a three to five times higher risk for testicular cancer (ge ...

Andrology
Andrology (from grc, ἀνήρ, ''anēr'', genitive , ''andros'', "man"; and , ''-logia'') is a name for the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. It is the counterpart to gynaecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health. Process Andrology covers anomalies in the connective tissues pertaining to the genitalia, as well as changes in the volume of cells, such as in genital hypertrophy or macrogenitosomia. From reproductive and urologic viewpoints, male-specific medical and surgical procedures include vasectomy, vasovasostomy (one of the vasectomy reversal procedures), orchidopexy and circumcision as well as intervention to deal with male genitourinary disorders such as the following: History Unlike gynaecology, which has a plethora of medical board certification programs worldw ...
