Cryptorchidism(Site not responding. Last check: )
Cryptorchidism is a condition in which either one or both testes (testicles) fails to descend fully into the scrotum.
It appears that cryptorchidism is polygenetic (involves multiple genes), and therefore elimination of this condition from a gene pool is difficult.
In spite of the fact that bilateral cryptorchid dogs are sterile, both bilateral and unilateral cryptorcids should be neutered, to reduce the risk of possible future complications.
International braz j urol - Study on the incidence of testicular and epididymal appendages in patients with ...(Site not responding. Last check: )
In patients with cryptorchidism we found testicular appendages in 23 cases (41.8%), epididymal appendage in 9 (16.3%), testicular and epididymal appendage in 8 (14.5%), 2 epididymal appendages and 1 testicular in 1 (1.8%), and absence of appendages in 14 (25.4%) cases.
Cryptorchidism is one of the most common congenital pathologies in males, with an incidence of 2 to 5% in full-term births, which can reach 30% in premature births (9-11).
Johansen TEB: Anatomy of the testis and epididymis in cryptorchidism.
Cryptorchidism is a medical term referring to absence from the scrotum of one or both testes.
Surgical correction is by palpation of the retained testicle and subsequent exploration of the inguinal canal or abdomen.
Cryptorchidism is also common in infants with abdominal wall defects, such as exomphalos or omphalocele, gastroschisis and extrophy of the bladder (19).
Cryptorchidism is distinct from the situation when the testicle is "retractile," meaning that it can be brought into the scrotum by external manipulation or is seen in the scrotum sometimes.
Cryptorchidism occurs when the testis fails to descend into its normal postnatal location and may be found in the abdomen, in the inguinal canal, or at the external ring (prescrotal).
The incidence of cryptorchidism in premature male infants is 9.2~30%, and in full-term infants is 3.4~5.8%.
Cryptorchidism is also common in infants with abdominal wall defects, such as exomphalos or omphalocele, gastroschisis and extrophy of the bladder (19).
Ectopic cryptorchidtestes are rare (< 5%), and occur in the perineum, prepubic region, thigh, or the contralateral inguinal canal (transverse testicular ectopia) (27).
Hormone therapy remains controversial (45,46) and is based on the assumption that cryptorchidism is secondary to a deficiency of the hypothalamic-pituitary-gonadal axis.
In the even smaller minority of cryptorchid infants who have other obvious birth defects of the genitalia, further testing is crucial and has a high likelihood of detecting an intersex condition or other anatomic anomalies.
The reduction with unilateral cryptorchidism is subtle, with a reported infertility rate of about 10%, compared with about 6% reported by the same study for the general population of adult men.

Cryptorchidism or undescended hidden testis is the most common disorder of sexual differentiation in man with an incidence of 4.5 % at birth and decreases to 0.8 % at 1 year of age until adulthood.
Cryptorchidism is associated with impaired spermatogenesis due to high intra-abdominal temperature and increased incidence of testicular cancer.
Cryptorchidism can be considered as a cause of infertility in 2 %~9 % of infertile patients, and in testicular cancer 5 %~10 % of men have a history of cryptor-chidism.
Cryptorchidism is the absence of at least one testis in the scrotum.
The incidence of cryptorchidism is high and almost 3% of boys in the western countries are operated on for this condition.
Abnormalities in the hypothalamo-pituitary-testicular axis may result in cryptorchidism, and cryptorchidism is nearly almost present in individuals with a testis and abnormal sexual differentiation.
Cryptorchidism and hypospadias in sons of gardeners and farmers.
use extensive health and occupational data from Danish population databases to test a prediction that maternal use of estrogenic or anti-androgenic pesticides may be a risk factor for cryptorchidism (undescended testes) and hypospadias in their sons.
Statistical analyses of the data included included examination of a series of potential confounding variables, including year of birth, gestational age, parity, twin birth, a maternal history of previous stillbirth, parental age, nationality and professional status (self-employed, salaried employee, skilled worker, unskilled worker), and the occurrence of the same malformation in an older brother.

Cryptorchidism is one of the most common congenital pathologies in males, with an incidence ranging from 2 to 5% of term births, and can reach up to 30% in premature birth (1-3).
The positioning of the 140 cryptorchidtestes studied and its relation to the persistence of the processus vaginalis is shown in Table-1.

Cryptorchidism is the condition where one or both of a stallion's testicles do not descend from the abdominal cavity into the scrotum
It is also thought by some that cryptorchidism may be a genetic trait and passed on from a "crypt" stallion to his male offspring causing them to be "crypt" as well.
Upon admission, the surgeon stated that the colt was a cryptorchid and he would have to go into the abdomen of the horse to remove the large testicle that could not pass through the inguinal canal.
The major symptom of cryptorchidism is not being able to feel one or both of the testicles in the scrotum.
To diagnose cryptorchidism, the doctor, usually an urologist, may palpate the scrotum and abdomen to locate the testicles while the patient is in the squatting position or in a warm bath.
The patient should be aware if undergoing surgery for cryptorchidism, injury to the testicular blood vessels or vas deferens (the tube that carries sperm) might occur when performing an orchidopexy.
Cryptorchidism is a condition in which the testes fail to descend into the scrotum (unilateral cryptorchidism/monorchidism describes the condition in which only one testis descends).
Cryptorchidism is inherited as a sex-limited autosomal recessive trait.
Once cryptorchidism is diagnosed, ultrasonogram is frequently employed to locate the undescended testes or testis within the abdominal cavity or tissues adjacent to the scrotum.
Cryptorchidism is a condition present at birth in which one or both testicles fail to descend into the scrotum from where they develop in the abdomen.
Cryptorchidism is believed to be an inherited trait that could be passed on to the next generation if the animal is allowed to reproduce.
Cryptorchidism is an inherited disease and its occurrence cannot be prevented in the individual animal; however, castrating animals diagnosed with this condition may help reduce the incidence in the general population as a whole.
