Abstract

To investigate the prepubertal serum inhibin B levels in monorchid boys with compensatory testicular hypertrophy (CTH) and in surgically treated cryptorchid boys with normal testicular volume. Prospective study. Pediatric Division, University of Verona, Italy. Thirty-two prepubertal boys: 11 monorchids with CTH and 21 cryptorchids. For comparison we analyzed 15 healthy boys. All patients underwent a GnRH agonist test. Inhibin B measurement was performed at basal time. There was a significant difference in mean testicular volume between monorchid and cryptorchid or healthy children, with boys with CTH evidencing larger testicle volume. There was no significant difference in inhibin B levels between boys with CTH and cryptorchid, but the levels were significantly lower in both groups than in the control group. Boys with CTH had significantly higher serum levels of basal FSH than children with cryptorchid. The FSH peak response to GnRH agonist stimulation was significantly higher in boys with CTH than in those with cryptorchid. Monorchid infants with CTH showed low inhibin B and high FSH levels. Our finding may confirm the hypothesis that CTH is unable to prevent testicular insufficiency in adulthood. We suggest an early hormonal ...Continue Reading

COVID-19

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
