A developmental defect in which a TESTIS or both TESTES failed to descend from high in the ABDOMEN to the bottom of the SCROTUM. Testicular descent is essential to normal SPERMATOGENESIS which requires temperature lower than the BODY TEMPERATURE. Cryptorchidism can be subclassified by the location of the maldescended testis.
Urogenital Surgical Procedures
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
Exogenous agents, synthetic and naturally occurring, which are capable of disrupting the functions of the ENDOCRINE SYSTEM including the maintenance of HOMEOSTASIS and the regulation of developmental processes. Endocrine disruptors are compounds that can mimic HORMONES, or enhance or block the binding of hormones to their receptors, or otherwise lead to activating or inhibiting the endocrine signaling pathways and hormone metabolism.
Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER.
A number of syndromes with defective gonadal developments such as streak GONADS and dysgenetic testes or ovaries. The spectrum of gonadal and sexual abnormalities is reflected in their varied sex chromosome (SEX CHROMOSOMES) constitution as shown by the karyotypes of 45,X monosomy (TURNER SYNDROME); 46,XX (GONADAL DYSGENESIS, 46XX); 46,XY (GONADAL DYSGENESIS, 46,XY); and sex chromosome MOSAICISM; (GONADAL DYSGENESIS, MIXED). Their phenotypes range from female, through ambiguous, to male. This concept includes gonadal agenesis.
Prenatal Exposure Delayed Effects
Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. It includes pre-conception maternal exposure.
Spermatic Cord Torsion
The twisting of the SPERMATIC CORD due to an anatomical abnormality that left the TESTIS mobile and dangling in the SCROTUM. The initial effect of testicular torsion is obstruction of venous return. Depending on the duration and degree of cord rotation, testicular symptoms range from EDEMA to interrupted arterial flow and testicular pain. If blood flow to testis is absent for 4 to 6 h, SPERMATOGENESIS may be permanently lost.
International trends in rates of hypospadias and cryptorchidism. (1/499)Researchers from seven European nations and the United States have published reports of increasing rates of hypospadias during the 1960s, 1970s, and 1980s. Reports of increasing rates of cryptorchidism have come primarily from England. In recent years, these reports have become one focus of the debate over endocrine disruption. This study examines more recent data from a larger number of countries participating in the International Clearinghouse for Birth Defects Monitoring Systems (ICBDMS) to address the questions of whether such increases are worldwide and continuing and whether there are geographic patterns to any observed increases. The ICBDMS headquarters and individual systems provided the data. Systems were categorized into five groups based on gross domestic product in 1984. Hypospadias increases were most marked in two American systems and in Scandinavia and Japan. The increases leveled off in many systems after 1985. Increases were not seen in less affluent nations. Cryptorchidism rates were available for 10 systems. Clear increases in this anomaly were seen in two U.S. systems and in the South American system, but not elsewhere. Since 1985, rates declined in most systems. Numerous artifacts may contribute to or cause upward trends in hypospadias. Possible "real" causes include demographic changes and endocrine disruption, among others. (+info)
Management of the impalpable testis: the role of laparoscopy. (2/499)PURPOSE: To evaluate the use of laparoscopy in the management of the impalpable testis. DESIGN: A retrospective analysis of the clinical findings, interventions, and outcome in 87 consecutive boys undergoing laparoscopy for 97 impalpable testes. RESULTS: Fifty seven testes were either absent (n = 35) or present as a small remnant (n = 22), which was removed at contemporaneous groin exploration. There were 27 intra-abdominal testes, including four hypoplastic testes, which were removed laparoscopically. The 13 remaining viable testes were located in the groin. Conventional orchidopexy followed laparoscopy for 21 testes, and was successful in 17 cases. Two stage laparoscopically assisted Fowler Stevens orchidopexies were performed for 13 intra-abdominal testes, with eight satisfactory results. Ultrasound evaluation significantly reduced the number of conventional orchidopexies following laparoscopy. IMPLICATIONS: Laparoscopy is a rational and safe approach for precise localisation of the impalpable testis. Laparoscopically assisted two stage orchidopexy is a successful treatment procedure for intra-abdominal testes. (+info)
Experimental cryptorchidism induces a change in the pattern of expression of LH receptor mRNA in rat testis after selective Leydig cell destruction by ethylene dimethane sulfonate. (3/499)In the rat, the cytotoxic drug ethylene dimethane sulfonate (EDS) selectively eliminates mature Leydig cells (LCs) from testicular interstitium, activating a complex process of proliferation and differentiation of pre-existing LC precursors. We observed previously that after EDS treatment, the early LC precursors persistently express a truncated 1.8 kb form of LH receptor (LHR) mRNA. This prompted us to study whether experimental cryptorchidism, known to alter the process of LC repopulation, can influence the pattern of testicular LHR mRNA expression after EDS administration. EDS treatment completely eliminated mature LCs both in control and unilaterally cryptorchid (UC) rats. This response was followed by gradual reappearance of newly formed, functionally active LCs, as evidenced by the recovery in testicular LHR content and plasma testosterone levels in both experimental groups. Noteworthy, the rate of LC repopulation was higher in the abdominal testes of UC rats, in keeping with previous findings. Interestingly, the 1.8 kb LHR transcript was persistently expressed in scrotal testes at all time-points, but undetectable upon Northern hybridization in abdominal testes at early stages after EDS administration, when low levels of expression of truncated LHR transcripts could only be detected by semi-quantitative RT-PCR analysis. In addition, the faster LC repopulation in cryptorchid testes was associated with precocious recovery of the complete array of LHR mRNA transcripts, including the 1.8 kb species. These changes appeared acutely and irreversibly, as unilateral positioning of scrotal testes into the abdomen resulted in a rapid loss of expression of the 1.8 kb LHR transcript, whereas scrotal relocation of the UC testes failed to alter the pattern of LHR gene expression. In conclusion, experimental cryptorchidism changes the pattern of LHR mRNA expression in rat testis after selective LC destruction by EDS. This change, i.e. repression of the 1.8 kb LHR transcript after EDS administration, is acute and irreversible, and likely related to the impairment of testicular microenvironment following cryptorchidism. However, even though at low levels, the expression of truncated forms of LHR mRNA appears to be a universal feature of proliferating LC precursors. The UC testis may represent a good model for analysis of the regulatory signals involved in the control of LHR gene expression. (+info)
Ooplasmic injections of rabbit round spermatid nuclei or intact round spermatids from fresh, cryopreserved and cryostored samples. (4/499)We compared the outcome of ooplasmic round spermatid nuclear injections (ROSNI) versus intact round spermatid injections (ROSI). Rabbit round spermatid nuclei and intact round spermatids were recovered and injected into rabbit oocytes (groups A and B, respectively). Fertilization, cleavage and embryonic development rates were compared. In additional studies, five protocols for cryopreservation of round spermatids and two protocols for cryostorage of round spermatids were applied. The outcome of ROSNI techniques using frozen-thawed or cryostored-warmed round spermatids was evaluated. The cleavage rate and the overall morula plus blastocyst development rate were significantly larger in group A than group B. ROSNI procedures are superior to ROSI techniques in the rabbit. The largest fertilization, cleavage and embryonic development rates after ROSNI techniques using cryopreserved or cryostored round spermatids were demonstrated in groups of round spermatids in which a mixture of seminal plasma plus test yolk buffer was employed as an extender, and dimethyl sulphoxide plus a high concentration of glycerol served as cryoprotectants. It appears that the seminal plasma contains factors protecting round spermatids during cryopreservation or cryostorage, and/or the employment of two cryoprotectants has a beneficial role in the maintenance of round spermatid reproductive capacity.

Risk factors for testicular cancer: a case-control study in twins. (5/499)Early life and anthropometric risk factors for testicular cancer were examined in a case-control study in England and Wales in which affected male twins were compared with their unaffected male co-twins. Questionnaire data was obtained for 60 twin pairs. Significantly raised risk of testicular cancer occurred in twins who had longer arms and legs than their co-twin. There was a significant excess of testicular cancer reported in non-twin brothers, as well as in twin brothers, of cases. Risk was also significantly raised in relation to cryptorchidism. The results on limb length suggest that factors, perhaps nutritional, affecting growth before puberty, may be causes of testicular cancer. The results on risk in brothers add to evidence of a large genetic component in aetiology of the tumour. The risk associated with cryptorchidism in the twins accords with the hypothesis that cryptorchidism is causally associated with testicular cancer because it is a cause of the malignancy, rather than because the same maternal factors experienced in utero cause both conditions.

Improvement of spermatogenesis in adult cryptorchid rat testis by intratesticular infusion of lactate. (6/499)In order to test the hypothesis that a lack of energy could be a cause of germ cell death at high temperatures, cryptorchid rats testes were infused with lactate, delivered by osmotic pumps over 3-15 days. In cryptorchid testes, the spermatids and spermatocytes were lost between 3 and 8 days. In cryptorchid testes supplemented with lactate, elongated spermatids persisted in a few seminiferous tubules at Day 15. Elimination of round spermatids occurred progressively between 3 and 15 days, mostly at stage VIII. The loss of spermatocytes increased after 8 days, and 30% of seminiferous tubules still contained meiotic or meiotic plus spermiogenetic cells at Day 15. After 8 days, the chromatin of step 8 round spermatids was abnormal and nuclear elongation did not commence. The Sertoli cell cytoplasm that was retracted toward the basal compartment of the seminiferous epithelium could not hold the germ cells of the adluminal compartment. Therefore, attachment of germ cells to Sertoli cells and the supply of lactate seem necessary for the development of germ cells at high temperatures. The improvement in spermatogenesis in cryptorchid supplemented testes for several days is a new finding. (+info)
Incidence of testicular cancer in the United States: has the epidemic begun to abate? (7/499)In response to a report that testicular cancer incidence in non-Hispanic White males in Los Angeles county had fallen in the 1990s, particularly in young men, the authors analyzed data collected by the Surveillance, Epidemiology, and End Results (SEER) program from 1973 to 1995. While the incidence rate of testicular cancer in US White males ages 15-64 years did stabilize in the first half of the 1990s, after a number of years of a steady increase, there was no indication of an actual decline.

Arrest of spermatogonial differentiation in jsd/jsd, Sl17H/Sl17H, and cryptorchid mice. (8/499)The nature of the spermatogenic arrest in cryptorchid C57Bl mice and in jsd/jsd and Sl17H/Sl17H mutant mice was identified by studying whole mounts of seminiferous tubules. In all three types of mice, virtually only A spermatogonia were found, topographically arranged in clones of 1 to 16 (rarely more) cells. These clonal sizes are typical for undifferentiated spermatogonia. The proportion of these cells lying in chains of more than 2 cells (50-70%) was comparable to that seen in epithelial stages VII-VIII in the normal epithelium. It is concluded that in all three types of mice, spermatogenesis is arrested at the point where the undifferentiated A spermatogonia, specifically A(al) spermatogonia, differentiate into the first generation of the differentiating-type spermatogonia, the A1 spermatogonia. The remaining A spermatogonia were proliferating, but no accumulation of spermatogonia was present, as spermatogonial apoptosis also took place. Spermatogonial clones of all sizes were seen to undergo apoptosis, but there were relatively many large apoptotic clones, indicating that the clones became more vulnerable when they became larger. In contrast to what is seen in the normal epithelium, odd-numbered clones, not composed of 2(n) cells, were present, as well as clumps of 2 or more spermatogonial nuclei in the same cytoplasm, in all three types of mice. This indicates a lack of integrity of spermatogonial clones, also observed in other situations with a relative paucity of cells on the basal membrane. It is concluded that the differentiation of the undifferentiated spermatogonia, affected in all three types of mice as well as in vitamin A-deficient animals, is a rather vulnerable point in the spermatogenic developmental pathway.

Impaired Sertoli cell function in experimental cryptorchidism in the rat | Meta
The production of testicular androgen-binding protein (ABP), as a measure of Sertoli cell function, was studied after unilateral or bilateral experimental cryptorchidism in adult rats. Two or 4 weeks after the testis had been translocated to the abdomen, no major changes were found in the concentration of ABP per mg protein, although there was a marked and progressive decrease in ABP content per testis. However, the rate of ABP production was greatly decreased, as measured by the accumulation of ABP during 16-h ligation of the efferent ducts or by the production of ABP by testis mince in an in vitro system. This indicates that the Sertoli cell function is severly impaired by the intra-abdominal position. ...
SPAG5 mRNA is over-expressed in peripheral blood leukocytes of patients with Downs syndrome and cryptorchidism. | IRIS...
Men with Downs syndrome (DS) have an increased risk of cryptorchidism, but the mechanisms causing its onset are not clear. Cryptorchidism causes a primary testiculopathy responsible for infertility. SPAG5 mRNA is predominantly expressed in testis in pachytene spermatocytes. This observation prompted us to evaluate the expression of SPAG5 gene in five DS men with cryptorchidism and five normal healthy men (controls) by quantitative real-time PCR in peripheral blood leukocytes. We found that SPAG5 is over expressed in the five men with DS and cryptorchidism compared with five age- and sex-matched normal controls. This finding suggests that the increased expression of this gene may play a pathogenic role durin testicular development in subjects with DS and cryptorchidism.. Men with Downs syndrome (DS) have an increased risk of cryptorchidism, but the mechanisms causing its onset are not clear. Cryptorchidism causes a primary testiculopathy responsible for infertility.

OCT 4 immunohistochemistry in postpubertal cryptorchidism - Open Medicine - Volume 6, Issue 2 (2011) - PSJD - Yadda
Patients with cryptorchidism are at an increased risk for germ cell testicular cancer. OCT 4 has been shown to be a sensitive and specific marker for some types of germ cell testicular cancer. We undertook this study to establish whether OCT 4 immunohistochemistry is a useful tool in the pathohistologic evaluation of postpubertal patients with cryptorchidism. Seventeen postpubertal patients underwent orchidectomy for cryptorchidism at our center since 1997. Immunohistochemical staining with OCT 4 was performed on these samples. Characteristic OCT 4 nuclear staining was positive in two patients. One patient was correctly diagnosed on previous pathohistological evaluation, while OCT4 immunohistochemical staining revealed previously unidentified intratubular germ cell neoplasia in the other patient. OCT 4 immunohistochemistry can be useful in diagnosing a testicular germ cell tumor in patients with cryptorchidism. If we consider a low number of postpubertal patients with cryptorchidism a benefit of ...
The Fate of Spermatogonial Stem Cells in the Cryptorchid Testes of RXF by Lydia Ferguson, Javier J. How et al.
The environmental niche of the spermatogonial stem cell pool is critical to ensure the continued generation of the germ cell population. To study the consequences of an aberrant testicular environment in cryptorchidism we used a mouse model with a deletion of Rxfp2 gene resulting in a high intra-abdominal testicular position. Mutant males were infertile with the gross morphology of the cryptorchid testis progressively deteriorating with age. Few spermatogonia were identifiable in 12 month old cryptorchid testes. Gene expression analysis showed no difference between mutant and control testes at postnatal day 10. In three month old males a decrease in expression of spermatogonial stem cell (SSC) markers Id4, Nanos2, and Ret was shown. The direct counting of ID4+ cells supported a significant decrease of SSCs. In contrast, the expression of Plzf, a marker for undifferentiated and differentiating spermatogonia was not reduced, and the number of PLZF+ cells in the cryptorchid testis was higher in three month

Undescended testicles (cryptorchidism) is the most significant risk factor for testicular cancer.. About 3-5% of boys are born with their testicles inside their abdomen. They usually descend into the scrotum during the first year of life, but in some boys the testicles dont descend. In most cases, testicles that dont descend by the time a boy is one year old descend at a later stage. If the testicles dont descend naturally, an operation known as an orchidopexy can be carried out to move the testicles into the correct position inside the scrotum.. Its important that undescended testicles move down into the scrotum during early childhood because boys with undescended testicles have a higher risk of developing testicular cancer than boys whose testicles descend normally. Its also much easier to observe the testicles when theyre in the scrotum.. Men with undescended testicles are about three times more likely to develop testicular cancer than men whose testicles descend at birth or shortly ...

Cortes D, Thorup J, Petersen BL. Testicular neoplasia in undescended testes of cryptorchid boys-does surgical strategy have an impact on the risk of invasive testicular neoplasia? Turk J Pediatr 2004; 46 (supplement): -42.. We investigated whether or not surgical strategy has an impact on the risk of invasive testicular neoplasia in cases of cryptorchidism. We made a database study of the incidence of testicular neoplasia at surgery for cryptorchidism in childhood, and evaluated if such abnormalities were found in special categories of patients, and also of the incidence of testicular neoplasia after orchiopexy with a simultaneous testicular biopsy in childhood.. At surgery for cryptorchidism the risk of testicular neoplasia was 7/182 (4%) in cases with intra-abdominal testis, abnormal external genitalia other than cryptorchidism, or diagnosed abnormal karyotype, versus no case in the 1281 patients without these characteristics (Fisher\s exact test, ...

Cryptorchidism - Eugonia
Cryptorchidism is the congenital abnormality in which the testicle has not descended into the scrotum.. Testicles are formed in the fetal abdomen and migrate through the groin into the scrotum in the 6th month of pregnancy. If this doent happen, cryptorchidism appears.. Cryptorchidism due to testicular overheating (temperature, 34 ° C) when the testis is outside the scrotum, causes atrophy of the cells that produce the spermatozoa. Testicular overheating also increases the incidence of malignant tumors. For these reasons, in case of persistent cryptorchidism, it is preferable to operate in a young age (about 1.5 years old). It has been shown that men who havent performed a surgery till the age of two, show problems with the quality of semen in their adult life.. ...
Undescended Testes (Cryptorchidism) | Department of Urology
Cryptorchidism (or undescended testes) is a condition seen in newborns when one or both of the male testes have not passed down into the scrotal sac. About 10% of cases involve both testes. Cryptorchidism is more commonly seen in premature males because the testes do not descend from the abdomen to the scrotal sac until the seventh month of fetal development. ...
Surgical findings in cryptorchidism in children with Zika-related microcephaly: a case series | BMC Urology | Full Text
Complications in the urinary tract related to congenital Zika syndrome have recently been reported. One complication, cryptorchidism, has been reported by the Microcephaly Epidemic Research Group/MERG, in Pernambuco/Brazil. The present article describes for the first time the surgical findings in a case series of boys with Zika-related microcephaly and cryptorchidism, who underwent surgical testicular exploration as a contribution to better understand the possible mechanisms involved in gonads formation and descent. A total of 7 children (11 testicular units), aged 3 to 4 years, were submitted to inguinal or scrotal orchidopexy for the treatment of palpable cryptorchidism between August 2019 and January 2020. Characteristics of the gonads and its annexes related to appendixes, testis-epididymis dissociation, gubernacular insertion, and associated hydroceles and/or hernias were described. Measures in centimetres were taken for volume calculate. We found a low prevalence of testicular and epididymal

Sonographic evaluation of fetal scrotum, testes and epididymis
Cryptorchidism or undescended testicles involves the failure of the testes to descend permanently in their terminal scrotal position . The estimated incidence at birth is 2-3.4% [7,17,81], although up to one-third of the cases resolve spontaneously during the first 3 months . Seventy-five percent of the cases are usually unilateral and the undescended testes can be palpated in the inguinal canal . Etiology is not clear, although a variety of risk factors such as defects in specific genes, prematurity, low birth weight, intrauterine growth restriction, alcohol consumption, and maternal smoking have been suggested [26,80,81,83-86]. The main complications include reduced fertility, an increased risk of testicular cancer, and the possibility of associated abnormalities. Evidence suggests that both the location and the time of cryptorchidism correlate with the loss of germ cells and Leydig cells . Paternity rates are similar in case of unilateral cryptorchidism, but significantly ...
Non-visible Testis (Cryptorchidism) - Pediatric Surgery
Non-visible Testis (Cryptorchidism). External genitals in a toddler with a non-visible testis of the right side. The left testis is visible and palpable in the corresponding scrotum. The right testis is neither visible nor palpable in the scrotum. The diagnosis is cryptorchidism of the right side. First of all, the history and the clinical examination can possibly tell which type of cryptorchidism is present. Because the right scrotum is smaller than the left, the right testis must (if present at all) always lie above the scrotum. Notice the relatively high position of the left testis within the left scrotum. ...
Normally testicles develop in the abdomen, near the kidney, and descend through the abdominal wall, then through the inguinal canal, and enter the scrotum. Cryptorchidism (or undescended testes) is a condition seen in newborns when one or both of the male testes have not passed down into the scrotal sac. Thirty percent of cases are bilateral (involve both testes).. Undescended testes may occur for several reasons. Known causes may include hormonal disorders, abdominal wall disorders, and chromosomal defects. Retractile testes can occur in boys where the testicle descended completely but a muscle reflex causes a testicle to move back and forth from the scrotum to the groin.. ...
Undescended Testes - The Paediatric Urology Partnership
The majority of undescended testicles - i.e. those that can be found and palpated in the groin - are brought down by a simple day case operation called an orchidopexy. The procedure takes about 45 minutes, and involves moving the testicle into the scrotum and fixing a small hernia, which is often associated with an undescended testicle.. If the testicle cannot be felt, it primarily needs to be located. This is achieved with laparoscopy, placing a telescope into the abdomen via the belly button, and seeking out the testicle in a higher position. When located, it may be possible, usually through a 2 step laparoscopic approach, to bring the testicle down into the scrotum. If it is an abnormal testicle, or has failed to completely develop, it would be necessary to protect the remaining testicle on the other side, by performing a fixation of this testicle, within the scrotum. This prevents the possibility of twisting and/or damage, later in life.. ...
Combined Anomalies 2 (Cryptorchidism) - Pediatric Surgery
Combined Anomalies 2 (Cryptorchidism). Operative findings in a toddler with right cryptorchidism. Below, the testis, and above, the epididymis is visible. The distance between the two organs is twice the width of the testis corresponding to 1.5 to 2.0 cm. This anomaly is called testicular-epididymal fusion abnormality. The sperm which is produced later in life has no connection to the epididymis and spermatic cord. The latter may be interrupted, too, as an additional combined malformation. Both anomalies may be detrimental to the fertility which is often already diminished by the cryptorchidism, and must be described in the protocol of the surgeon. ...

MONDAY, June 17 (HealthDay News) -- Fetal exposure to the chemical bisphenol A (BPA) has been linked to low levels of a key developmental hormone in newborn boys with undescended testicles, according to an early new study.. The research adds to the list of growing health concerns related to BPA, which is widely used in food packaging. Government studies have shown that 92 percent of Americans have detectable levels of BPA in their bodies.. This study focused on boys with cryptorchidism, the medical term for undescended testicles. The condition occurs in 2 percent to 5 percent of newborn boys, according to the authors, and requires surgery to bring the testes out of the abdominal cavity. Boys born with cryptorchidism have an increased risk of fertility problems and testicular cancer in adulthood.. The researchers found that boys with cryptorchidism who had high levels of BPA in their fetal cord blood also had low levels of the hormone insulin-like 3, or INSL3, one of two hormones that regulate ...

Twin boys, both of whom had hypospadias and bilateral cryptorchidism, each developed a left-sided Wilmss tumour. The first twin was found to have an advanced multifocal tumour at the age of 15 months and died with local recurrence and pulmonary metastases. The diagnosis was made in the second twin one month later and at nephrectomy the tumour was found to be encapsulated without metastases; he is disease-free 12-years later. Although the histological appearances were similar in each twin, the tumours did not develop at the same rate and did not show the mirror-image pattern suggested for embryonal tumours in identical twins.. ...

Management of Cryptorchism and Risk of Testicular Cancer : American Journal of Epidemiology - oi
Cryptorchism is an established risk factor for testicular cancer, but the role of age at surgical correction is unclear. The authors investigated this relation using information obtained from comprehensive medical records dating to childhood. They conducted a case-control study of 183 Kaiser Permanente members, who were diagnosed with testicular cancer during 1973-1996 and who were 15 years or younger when they first joined the health plan, and 551 controls. Notes pertaining to the testes were reviewed up to the cases diagnosis date or comparable date among the controls. The odds ratio for the association of a history of cryptorchism with testicular cancer risk was 4.8 (95% confidence interval (CI): 1.9, 11.8). Compared with no history of cryptorchism, men with a history who had natural descent or successful orchiopexy by the 11th birthday were not at increased risk of testicular cancer (odds ratio = 0.6, 95% CI: 0.08, 5.4). However, successful treatment of cryptorchism only after the 11th ...
Magnetic Resonance Imaging for Locating Nonpalpable Undescended Testicles: A Meta-analysis | Review Articles | Pediatrics
Cryptorchidism is a common anomaly that often warrants early surgical management. Preoperative identification and location of testicles can help to determine the optimal type of procedure and allow for appropriate advance planning. On the basis of the imaging findings, the surgeon can appropriately counsel the patient and alter the operative approach as needed. In the case of absent or vanishing testicles, imaging findings could obviate the need for surgical exploration altogether.. Various imaging techniques have been suggested for use in identifying and locating nonpalpable testicles preoperatively in young boys, with varying limitations including expense, invasiveness, technical difficulty, radiation risk, need for contrast medium, effectiveness in particular groups of subjects, and need for sedation. Because ultrasound, which is the least expensive and frequently used technique of all imaging tools, had been shown to have low sensitivity in identifying nonpalpable testicles preoperatively in ...

Ridgling - Wikipedia
A ridgling (also spelled ridgeling), or rig, is a cryptorchid; a male animal with one or both testicles undescended, usually describing a ram, bull, or male horse, but cryptorchidism also can be an issue in dogs and cats. Because the heat inside the body is too high for sperm to survive, an undescended testicle is non-functional. The condition is most often discussed in the horse world, as the health behavioral issues surrounding adult males with the condition are of concern to owners and handlers of such animals. Although the rate that testicles descend varies between individual animals, horses over three years with the condition are generally castrated. Surgery called a cryptorchidectomy is used to remove the retained testicle, but different procedures are used, depending on the location inside the body cavity. An undescended testicle is not a serious or life-threatening condition, though it may cause the animal discomfort at times. This condition can be corrected by surgery to place the ...

Chapter 24. Genital Tumors | Smith & Tanaghos General Urology, 18e | AccessMedicine | McGraw-Hill Medical
Although the cause of testicular cancer is unknown, both congenital and acquired factors have been associated with tumor development. The strongest association has been with the cryptorchid testis. Approximately 7-10% of testicular tumors develop in patients who have a history of cryptorchidism; seminoma is the most common form of tumor these patients have. However, 5-10% of testicular tumors occur in the contralateral, normally descended testis. The relative risk of malignancy is highest for the intra-abdominal testis (1 in 20) and is significantly lower for the inguinal testis (1 in 80). Placement of the cryptorchid testis into the scrotum (orchiopexy) lowers the risk of malignancy if it is performed prior to the age of 13 (Pettersson et al, 2007). ...
Use of mild painkillers in pregnancy is associated with an increased risk of male reproductive problems - Healthcanal.com :...
Research published in Europes leading reproductive medicine journal Human Reproduction today (Monday 8 November) shows that women who took a combination of more than one mild analgesic during pregnancy, or who took the painkillers during the second trimester of pregnancy, had an increased risk of giving birth to sons with undescended testicles (cryptorchidism) - a condition that is known to be a risk factor for poor semen quality and testicular germ cell cancer in later life. . The researchers from Denmark, Finland and France found that women who used more than one painkiller simultaneously (e.g. paracetamol and ibuprofen) had a seven-fold increased risk of giving birth to sons with some form of cryptorchidism compared to women who took nothing.. The second trimester appeared to a particularly sensitive time. Any analgesic use at this point in the pregnancy more than doubled the risk of cryptorchidism. Of the individual painkillers, ibuprofen and aspirin approximately quadrupled the risk of ...

TY - JOUR. T1 - The effect of experimental cryptorchism on the isozymes of lactate dehydrogenase in mouse testes. AU - Goldberg, Erwin. AU - Hawtrey, Christopher. PY - 1968/1/1. Y1 - 1968/1/1. N2 - Unilateral cryptorchism produced by experimental retention of one testis in the abdomen of the mouse results in a rapid decrease in the weight of that testis. At the same time the specific activity of lactate dehydrogenase (LDH) decreases to 70% of the normal value. The sperm‐specific isozyme, LDH‐X, declines from 41% of the total activity to only 16% after eleven days in the abdomen. All LDH‐X activity is lost by post‐operative day 24. The relative proportion of the other isozymes of LDH increase following the operation. LDH‐5, absent from the mature testis, is detectable in the cryptorchid testis at post‐operative day 28 and represents 15% of the total LDH activity. These observations provide further support of the suggestion that LDH‐X is only found in the testes when meiosis is ...
Morphologic and endocrinologic characteristics of retained canine tests | accedaCRIS
The objective of this study was to assess macroscopic and microscopic characteristics of the testes in unilaterally cryptorchid dogs (n=16 and n=13, respectively). An additional goal was to measure and compare plasma levels of testosterone between the cryptoid (n=13) and control dogs (n=16). The size and weight of the retained tested were lower (P ,0.01) compared with the descended testes in the unilaterally cryptoid dogs of different breeds, but there was no difference between the inguinal and abdominal cryptoid testes (P ,0.01). Spermatogenesis was significantly suppressed in the cryptorchid testes compared with the contralateral testes of the unilaterally cryptorchid dogs. The number of Leydig cells was higher (P ,0.01) in the cryptorchid than in scrotal testes. Plasma concentration of testosterone did not vary (P ,0.1) between the cryptoid and control dogs. Normal endocrine function could be maintained in the cryptorchid dogs, despite the smaller testicular size of the retained testes ...

Dont count your chickens: December 2012
I have been running non stop since Friday night. The holiday parties and errands for our foster son. I was bone tired last night and looking forward to some rest but Titus decided to have a fussy night. I slept in 40 minute intervals and was awoken for good at 4:45. I know, its a high class problem to have. I grumbled but treasured the hour of snuggle time he allowed me before he decided to play. Titus saw the pediatric urologist for his final post op checkup. He did spring a leak mid shaft. This is called a fistula and there was a 20% chance of it occurring. He will have a second surgery in February. He also has an undescended testicle. I suppose they will correct that within a couple of months of the fistula repair. Hypospadias and undescended testicles are on the same gene and often go together. If we get everything corrected Titus should have normal sexual function as an adult. The urologist really wants him to see the pediatric endocrinologist. Titus is still so very small. He is 13 months ...

A baby boy with cryptorchism, inguinal hernia and internal female genitalia: the persistent Mullerian duct syndrome]
During operation for a right inguinal hernia, a baby boy aged 3 months was discovered to have internal female genitalia. Biopsies were taken from the gonads and blood was sent for karyotyping. The biopsies showed normal testicular tissue and the karyotyping result was 46XY, so the diagnosis of persistent Mullerian duct syndrome (PMDS) was made. Recovery was uneventful. At the age of 2 he underwent bilateral orchidopexy. PMDS is a rare disorder of the MIF synthesis or receptor. Patients present with cryptorchism, inguinal herniation of Mullerian structures, or problems related to the abnormal urinary tract, such as infection or stone formation. In cryptorchism, orchidopexy and life-long palpatory follow-up are advised. If urological symptoms occur, surgical removal of the Mullerian remnants may be considered. The prognosis for fertility is poor ...
Increased Testicular Cancer Risk | Urology Care Alliance
According to a new study, boys whose testes have not descended into the scrotum at birth, may be nearly three times more likely to develop testicular cancer later in life.. Previous studies of the condition called cryptorchidism (undescended testes) have shown that in 5 to 10 percent of testicular cancer patients undescended testes were present.. However, it has remained unclear exactly how much a boys risk of testicular cancer is increased if he was born with undescended testes.. The new study was designed to answer that question and concluded that boys with undescended testes were 2.9 times more likely to develop testicular cancer. About 6 percent of newborn boys are born with undescended testes.. Researchers must now consider whether this degree of increased cancer risk means that boys born with the condition should undergo heightened surveillance for testicular cancer in addition to current close followup.. The study was published in the journal Archives of Disease in Childhood.. ...
Testicular Examination and Testicular Self-Examination - North Kansas City Hospital, Kansas City, MO
This is a complete physical exam of the groin and the genitals, which are the penis, scrotum, and testicles. Your doctor will feel the organs and check them for lumps, swelling, shrinking, and other signs of a problem. A genital exam is an important part of a routine physical exam for every teenage boy and man. Baby boys should also have their genitals checked for problems they were born with, such as an undescended testicle. An undescended testicle is more common in premature babies than in full-term babies.. Testicular cancer is rare, but it is the most common cancer in men younger than age 35. It often appears as a painless lump or swollen testicle. In the early stages of the cancer, the lump may be about the size of a pea. In many cases, this cancer is found by the man himself or by his sex partner. The chance of cure is very high when this cancer is found early and treated right away.. ...

Alström syndrome (AS) is a rare, autosomal recessive disorder characterized by progressive cone-rod dystrophy, childhood obesity, sensorineural hearing impairment, type 2 diabetes, hypogonadism, and additional abnormalities. Herein we report a 29-year-old man with progressive cone-rod dystrophy, hearing impairment, liver cirrhosis, bilateral cryptorchidism with hypergonadotropic hypogonadism, and type2 diabetes. He had severe insulin resistance and required high-dose insulin to treat his hyperglycemia. Genetic testingrevealed a mutation in exon 8 (c.4746C | A) of the Alström syndrome protein 1 (ALMS1) gene and this is the first report of this mutation in AS. It is difficult to lead to correct diagnosis without genetic test, and physicians should suspect AS when patients show early onset visual dysfunction, obesity, or type 2 diabetes.

Orchiopexy, also known as orchidopexy, is a surgical technique that can correct cryptorchidism and was successfully performed for one of the first times in 1877 in Scotland. Cryptorchidism, a condition where one or both of the testicles fail to descend before birth, is one of the most common male genital birth defects, affecting approximately 2 to 8 percent of full-term male infants, and around 33 percent of premature infants. Typically in the womb, male testes form within the abdomen, then descend into the scrotal area between twenty-five to thirty-five weeks gestation..

Several biological problems affecting the male testicles have been occurring with greater frequency over the past 50 years. The summary of the problem, which appeared in the 1993 journal, Environmental Health Perspectives(13), discussed the observed rise in testicular cancer and the medical conditions hypospadias and cryptorchidism, as well as the apparent declining sperm count among the overall male population. Hypospadias is when the testicles do not descend and cryptorchidism is when the opening to the penis appears on the underside of the penis.. According to the researchers at the Statistical Research Unit, University of Copenhagen, Denmark, cancer of the male testicles has increased over 3-fold from 1940 to 1980. The frequency of hypospadias (the opening of the penis on the underside) in England has doubled from 0.15% in 1964 to 0.36% in 1983. Similar increases were also reported from Sweden and Hungary. Recent British data also detected a near doubling of cryptorchidism. This problem has ...
Testicular Cancer | The MD Anderson Manual of Medical Oncology, 3e | AccessHemOnc | McGraw-Hill Medical
Cryptorchidism is one of the few identifiable risk factors for the development of GCTs, although representing at most about 10% of cases. When present, cryptorchidism imparts a relative risk between 2.5 and 17.1 (7,8). This increased risk includes the contralateral testicle, even if descended normally or via orchiopexy. It is unclear if orchiopexy reduces the lifetime risk of GCTs, although data showing increased incidence even in the contralateral testicle support the theory that the etiology of GCTs lies in abnormal gonadal development rather than anatomic malposition (9,10). Men with a prior history of GCTs also have an increased risk of GCTs in the contralateral testicle, suggesting a genetic predisposition, although men with a family history of GCTs account for only 1.5% of patients with new diagnosis (11). A personal history of GCT carries an increased lifetime risk of secondary cancers, irrespective of histologic type (12). ...
AKC Canine Health Foundation
Background: Cryptorchidism, or retained testicles, is one of the common congenital problems in dogs. The testes of cryptorchids are more prone to testicular cancer and infertility. Therefore, cryptorchids and animals carrying genes for cryptorchidism should be eliminated from the breeding population. Some evidence exists to suggest that it appears to be a multigenic trait but single genes with large effects may exist. In earlier studies, the researchers utilized a candidate gene approach using 50 polymorphisms (called SNPs) in 22 candidate genes and found that collagen 2A1 (COL2A1) was significantly associated with cryptorchidism in Siberian Huskies. Now, they need to use the whole genome association analysis which typically provides more comprehensive analyses of chromosomal regions associated with a particular trait. This will then allow them to confirm previous findings or suggest other contributing regions or genes. Objective: The researchers will utilize a new tool called the canine SNP chip

Recent studies have revealed that testicular cancer is more common in men whove had an undescended testicle as a child and have a higher chance of getting testicular cancer; however it is treatable by surgery. Cancer in the testicles is called testicular cancer, which is part of the male reproductive system. It may be hereditary. People who suffer from infertility are at a major risk. After being treated for testicular cancer in one testis there is a risk of the other being affected, precautions must be taken after the first treatment is over and regular checkups is a must. Men who are taller have a higher risk of testicular cancer for some unknown reason. People who suffer with HIV or AIDS have a risk of developing testicular cancer. ...
Difference between revisions of 2014 Group Project 9 - Embryology
Testicular descent, which beings during the early foetal period, has been an area of research from the 1700s, when anatomists such as John Hunter began to notice the origin and development of the testicles and their location    . The mechanisms behind testicular descent has been debated for at least two centuries, beginning with anatomical dissections on both human and animal foetuses during the eighteenth and nineteenth centuries  , then enhancing with endocrinological discoveries during the twentieth century  . Many theories were proposed and revoked since the discovery of testicular descent. One of the earliest debates was between John Hunter and Albretch von Haller, who concluded that the foetal testis is intra-abdominal and the processus vaginalis remains opened, contrary to the results published by Hunter  . Hunters description of the gubernaculum, as a vascular and fibrous foetal structure, and the covering cremaster muscle led to further research ...
