Cryptorchidism is a very common anomaly of the male genitalia, affecting 2%-4% of male infants and is more common in premature infants. There are two separate stages of testicular descent. The first stage occurs at 8-15 weeks' gestation in the human fetus and is characterized by enlargement of the genito-inguinal ligament, or gubernaculum, and ...

Cryptorchidism remains a major cause of male infertility and can be associated with germ cell tumors. Recent reports regarding cause, diagnosis, treatment and outcome of this disorder continue to inform our understanding of this common and important problem.

Pathogenesis of Cryptorchidism
Hormone Research, 2008Cryptorchidism was induced experimentally by treating pregnant mice on the 14th day of pregnancy with 5 mg estrogen. Testes from cryptorchid and control newborn and adult mice were investigated with radioimmunoassay and electron microscopy. It was concluded that a normal Leydig cell function plays a decisive role in testicular descent.

The majority of instances of undescended testes occur sporadically, but cryptorchidism in more than one member of a family is not rare in our experience despite the paucity of published reports. Occurrence of cryptorchidism among siblings has been reported by several investigators.1-3 Charny and Wolgin described left-sided undescended testes in a ...

This paper is a historic review of two studies of the treatment of cryptorchidism. One was concluded 20 years ago with native LHRH, while the other took place 14 years ago and involved one of the potent LHRH analogues. The first study was initiated at the end of 1971-at a time when the different modes of action of the decapeptide were by far not ...

Semicastration in cryptorchidism of adults is the preferential therapy. A positive effect on fertility is usually to be expected. An aggravation did not occur in any case. If for any reason, in cases of cryptorchidism or especially if only one testis is present orchidopexy is carried out, there should be a periodical check-up of the patients in order ...

Pediatrics, 1973
The incidence of cryptorchidism in newborn infants is stated to be 3% to 4% by Curran and Curran in a recent article.1 The reference cited is a report by Scorer published in 1957.2 However, a review of the literature shows that the incidence of cryptorchidism in the full-term new born infant is slightly lower and in the low birth weight infant (birth ...

SUMMARY The incidence of cryptorchidism after the first year of age approximates 0.8 per cent of the male population. Prior to age one, spontaneous descent of cryptorchid testes may occur especially during the first three months of age but relatively rarely thereafter.

Nomenclature of cryptorchidism
European Journal of Pediatrics, 1993Despite the fact that cryptorchidism is a common congenital anomaly, our understanding of this problem is hampered by confusion and uncertainty regarding diagnosis and treatment. A major factor producing this confusion is the lack of a common terminology that describes to the reader (or listener) exactly what the author means by a given term. Herein is

Spermatogenesis in Cryptorchidism
2011Cryptorchidism or undescended testis is the most frequent congenital abnormality in newborn boys. The process of testicular descent to the scrotum is controlled by hormones produced in Leydig cells, insulin-like3, and androgens. Variation in genetic and environmental factors might affect testicular descent.
