Objective- Release of free radicals and oxidants following increased temperature of testis in cryptorchidism, play an important role in the producing testicular damage. The present study investigated the role of vitamin C as an antioxidant in protecting the testis against damage in experimental unilateral cryptorchidism. Design- Experimental study Animals- Forty five male adult Wistar–Albino ...

Cryptorchidism: When the testes do not descend, the condition is called ‘cryptorchidism’. The condition occurs in about 3% of full-term infants and about 30% of premature infants. Untreated cryptorchidism on both sides results in sterility because the cells involved in the initial development of sperm are destroyed by the higher temperature of the pelvic cavity. The chance of testicular cancer ...

PURPOSE To evaluate the relationship between unilateral or bilateral criptorchidism, patient age, primary location of the gonad and modality of treatment with testicular volume and hormonal status at 18 years in patients diagnosed and treated for cryptorchidism during childhood. MATERIALS AND METHODS Testicular volume, LH, FSH, and testosterone were evaluated in 143 young men at 18 years trea...

A clinical case of acquired unilateral cryptorchidism after herniotomy was described. Extensive degenerative changes were histologically observed not only in the cryptorchid testis but also in the scrotal one, and were regarded as underlying processes of sterility in the case of unilateral cryptorchidism . In experimental unilateral cryptorchidism in dogs, histologically demon strable spermatog...

Cryptorchidism is common in infants born preterm, yet the mechanism for its occurrence is still debated. In a study of 21 premature babies with cryptorchidism at 18 months post-term and 21 case matched controls, cryptorchid preterm infants failed to show the normal rise in plasma testosterone in the first postnatal week. This rise is thought to relate to residual maternal human chorionic gonado...

Germ cell death and their removal from the seminiferous epithelium are common in the affected testis in conditions of unilateral ischemia or cryptorchidism; the similarities and differences, however, have not been studied between these two conditions. The present study was designed to examine the severity of the effect on testicular germ cells during the initial stages of both ischemia and cryp...

The aim of this study was to evaluate the efficiency of low-dose hCG (human chorionic gonadotropin) (500 IU/week for 3 weeks) in the treatment of cryptorchidism and in the assessment of Leydig cell functions. We include 35 male patients who had been diagnosed with cryptorchidism by the pediatric endocrinology specialist in the study. Twenty-one cases (Group I) received 500 IU/week of hCG while ...

PURPOSE The frequency, significance and possible etiology of testicular ascent (acquired cryptorchidism) are characterized in light of the known incidence and natural history of congenital cryptorchidism, and data provided by longitudinal and epidemiological studies of ascended testes and orchiopexy rates. MATERIALS AND METHODS We comprehensively reviewed the literature addressing the epidemi...

BACKGROUND Recently, over-the-counter mild analgesic use during pregnancy has been suggested to influence the risk of reproductive disorders in the offspring. We examined the influence of maternal exposure to mild analgesics during pregnancy on the occurrence of cryptorchidism and hypospadia in their offspring. METHODS Associations between maternal exposure to mild analgesics during pregnancy...

BACKGROUND Androgens are crucial for normal testicular descent. Studies show that some pesticides have estrogenic or antiandrogenic effects, and that female workers exposed to pesticides have increased risk of having a boy with cryptorchidism. The main objective of the present study was to investigate whether pregnant women exposed to pesticides due to their work in horticulture experience exce...
