Endocrinological studies in undescended testes

Acta paediatrica Scandinavica
P E Waaler


A cross-sectional study was carried out on 168 boys aged 2.5-16.8 years with unilateral or bilateral testicular maldescent. Urinary excretion of testosterone, delta4-androstenedione, LH and FSH was investigated. The results were related to chronological age, bone age and sexual maturation stage. Urinary testosterone excretion was elevated in unilateral and bilateral cases of undescended testis under 9 years of age. The pubertal increase of testosterone excretion seemed to be moderately delayed in the patients. In pubertal stage V the testosterone excretion was normal. The mean testosterone/androstenedione relationship was normal in all age groups up to 14.9 years and increased in patients above this age. After HCG stimulation, the testosterone excretion increased at all ages studied whereas the androstenedione excretion increased only in bilateral cases under 11 years of age. Urinary LH excretion was diminished in bilateral cases aged 6.0-7.9 years and elevated in unilateral cases in pubertal stage V. Urinary FSH excretion was normal below 8 years of age, moderately elevated in bilateral cases aged 8.0-11.9 years and increased in unilateral cases in pubertal stage V. Patients with bilateral anorchia in pubertal stage I, had nor...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Cell Atlas Along the Gut-Brain Axis

Profiling cells along the gut-brain axis at the single cell level will provide unique information for each cell type, a three-dimensional map of how cell types work together to form tissues, and insights into how changes in the map underlie health and disease of the GI system and its crosstalk with the brain.
