Undescended testes: a consensus on management

European Journal of Endocrinology
E Martin Ritzén

Abstract

The mode of treatment best for undescended testes is controversial, and local traditions often override knowledge gained from randomized controlled studies. In order to reach a consensus within the Nordic countries on the current state-of-the-art of treatment, a group of specialists in testicular physiology, paediatric surgery/urology, endocrinology, andrology, pathology and anaesthesiology from all the Nordic countries met for 2 days. Before the meeting, reviews of the literature had been prepared by the participants. Judging from published meta-analyses, hormonal treatment has low efficacy. Although 15-20% of retained testes descend during hormonal treatment, one-fifth of these re-ascend later on. Also, treatment with human chorionic gonadotropin (hCG) may be harmful to future spermatogenesis through increased apoptosis of germ cells. Orchiopexy, on the contrary, results in about 95% anatomical success, with a low (about 1%) risk of complications. The optimal time for orchiopexy has also been debated. However, a recent randomized controlled study shows that surgery at 9 months of age is followed by a better post-operative growth of the testes than surgery at 3 years, which supports previous arguments for early surgery.

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
