cryptorchidism/fever

Decreased sperm count and motility were observed in men after induction of local testicular hyperthermia by raising the testicles into the inguinal canal during the day in adult volunteers. A similar technique in which the testicles were better maintained in the inguinal canal resulted in more

Artificial cryptorchidism or local testicular heat treatment can induce reversible oligospermia or azoospermia in monkeys and rats via germ cell apoptosis. Local warming of monkey testes in water at 43°C for 2 consecutive days (30 min per day) decreased the number of sperm in the semen by up to 80%

This study examined the capacity of abdominal organs, such as the scrotal testis, exposed to environmental temperature to hydrolyze pregnenolone sulfate. The cryptorchid state of exposure to 34 degrees C during 14 days decreased testis weight by 38 and 23%. But the enzymatic activity (nanomoles of

OBJECTIVE To investigate the role played by transforming growth factor beta receptor II (TGFbetaRII) in cryptorchidism-induced spermatocyte apoptosis. METHODS A unilateral cryptorchidism rat model was surgically established in 20-day-old male SD rats. Testis samples were collected 0, 4, 7, 14, and

Cryptorchidism, the most common endocrine disturbance in the newborn, is still present in 0.3% of all postpubertal men as monolateral or bilateral condition. The undescended testis, in postpubertal age, is permanently damaged, so about 80% of cryptorchids are subfertile or definitively sterile. In

Heterogeneity in malignant hyperthermia is being recognized with increasing frequency. In 1973, King described a subgroup of malignant hyperthermia patients with slowly progressive myopathy, short stature, kyphoscoliosis, pectus carinatum, cryptorchidism, and a characteristic facial appearance.

A 36-year-old man referred to our hospital with the chief complaint of painful left inguinal mass and fever. He had undergone left orchiopexy for undescended testis at 10 years of age. With the suspicion of an incarceration of inguinal hernia, an operation was performed. However, there was no hernia

King's syndrome is a sporadic genetic syndrome exhibiting characteristic facial features, short stature, and subclinical myopathy. Affected individuals are susceptible to malignant hyperthermia (MH) induced by anesthesia, stress, or trauma. The incidence of King's syndrome is uncertain as all

The mRNA of the mitochondrial uncoupling protein 2 (UCP2) was up-regulated by cryptorchidism, a testicular hyperthermic condition under which germ cells undergo severe apoptosis. We investigated whether UCP2 was able to protect germ cells from hyperthermia-induced apoptosis. UCP2 was predominantly

We report two cases of torsion of the spermatic cord in undescended testis. Case 1: A 23-year-old man was admitted to our hospital with the complaints of fever and left inguinal pain. He had cerebral palsy in his past history. Tentative diagnosis of acute epididymitis of left undescended testis was

A Negative correlation between spermatozoa output and serum gonadotropin levels, as well as between scrotal temperature and spermatozoa output, has been found in man. However, no studies have been done on the relationship between scrotal temperature and serum gonadotropin levels. This paper reports

Cryptorchidism, the failure of one or both testes to descend into the scrotum prenatally, occurs in 2.4%-5% of newborns. Many of these testes will descend spontaneously shortly after birth, but ~23% will remain undescended unless surgery is performed. Bilaterally cryptorchid men have a six times

OBJECTIVE Does elevated temperature-induced cystic fibrosis transmembrane conductance regulator (CFTR) down-regulation in Sertoli cells in cryptorchid testis disrupt testicular tight junctions (TJs) through the nuclear factor kappa B (NF-κB)/cyclooxygenase-2 (COX-2)/prostaglandin E(2) (PGE(2))

Leydig cells were isolated from testes of normal, cryptorchid and induced- varicocele rats. These cells were counted and coincubated with and without human Chorionic Gonadotropin (hCG) during 3 hours; thereafter, steroids were measured in the incubation media. Cryptorchid animals showed the lowest
