... of testicular cancer is increased two- to eight-fold in isolated cryptorchidism and usually occurs before the age of 40 years. By contrast, when cryptorchidism is associated with congenital hypogonadotropic hypogonadism, the risk of testicular cancer is unknown. Objective: The aim of this study was to determine...

These normative values are useful both for the evaluation and follow-up of cryptorchid, suboptimally descended, and retractile testes, as well as for the evaluation and follow-up...

...S.M.P.F. de Muinck Keizer-Schrama Hormonal treatment of cryptorchidism with a gonadotropic substance from pregnancy urine or with an anterior-pituitary-like substance dates from the early 1930s. Success rates varied from 25 to 100%. Subsequently, human chorionic gonadotropin (hCG) administered...

...M.B. Jackson A total of 3,559 boys were examined for cryptorchidism over a 2-year period. At birth, 5.9 % (210/3,534) had one or both testes undescended and at 3 months of age 1.61 % (57/3,534) still had an undescended testis. These figures represent an increase in undescended testis of 40...

... have conducted a modified double-blind study on the effect of human chorionic gonadotropin (hCG), gonadotropin releasing hormone (GnRH) and placebo on bilateral and unilateral maldescended testes. One hundred and fifty-five boys with bilateral and 88 boys with unilateral cryptorchidism fulfilled...

...V. Hesse; G. Fischer Two schedules of human chorionic gonadotropin (hCG) administration were compared in a study of 332 boys (473 testes) aged 1–13 years with cryptorchidism. One group of patients received 10 hCG injections according to the International Health Foundation (IHF) schedule while...

...P.E. Waaler; L. Aksnes The 24-hour urinary excretion of cyclic AMP was determined in 102 normal boys aged 1.9-16.9 years and in 136 cryptorchids aged 2.5 – 16.9 years. A marked increase of the normal cyclic AMP excretion was found in pubertal years. There was a positive correlation between urinary...

...F. Hadziselimovic; J. Girard; B. Höcht; M. von der Ohe; G. Stalder 62 cryptorchid boys aged 2–6 years were selected at random either for surgical or for hormonal LH-RH treatment. As all biopsies from boys operated show typical histological and ultrastructural signs of cryptorchidism, it can...
